Mazda 6 US-spec

Mazda 6 US-spec

The Mazda 6, made Zoom-Zoom the two most evocative words in the automotive lexicon. The sport sedan was the first Mazda vehicle to benefit from the spirit of a true sports car infused in a five-passenger, 4-door sedan. That revolutionary combination created a commotion in the mid-size class where strict practicality, affordability, and economy of operation usually leave no room for driving enjoyment. The original Mazda 6's vitality is what set it apart from competitors.

Times and tastes change. The all-new 2009 Mazda 6 takes everything learned in that first-generation car, as well as lessons learned from volumes of customer feedback, and proves Mazda's commitment to continuous improvement. Most important, though, this is the first Mazda vehicle designed, engineered, developed, and manufactured on US soil with the intention of surpassing American customer needs in countless categories.

To be widely recognized as the best vehicle available in the mid-size market, the Mazda 6's underlying concept rests solidly on three fundamental pillars:

A Sporty Appearance Integrated With A Highly Dynamic Character. Mazda's Zoom-Zoom spirit influences every aspect of the Mazda 6's visual appearance, driving personality, and core disposition. Kajiyama explains, "We sought an exterior design capable of stirring any observer's emotions and distinguishing the Mazda 6 from the competition. We also strived to achieve a dynamic character that encourages a strong level of interaction with the driver."

The Unique Experience. The Mazda 6 inspires pride of ownership. Notes Kajiyama, "By elevating the quality level with exquisite craftsmanship, each Mazda 6 will form a strong bond and a powerful emotional connection with its owner. This relationship is reinforced by driving pleasure keyed to adult tastes, comfort that the driver and every passenger can feel and appreciate, and numerous special features that make every trip, long or short, a highly memorable and pleasurable experience."

The Mazda 6 goes beyond existing mid-size sedan solutions to provide innovative packaging inside a larger envelope, highly flexible seating and storage space, and an unusually attractive appearance. Kajiyama adds, "By building on our strengths and accomplishments, we're able to make the Mazda 6 the most versatile, comfortable, and enjoyable automobile this company has ever produced. This is what we mean by the evolution of Zoom-Zoom."

TARGET MARKET

Over 2 million US buyers purchase a new mid-size automobile each year. Second only to full-size pickup trucks, the mid-size car segment is greater than that of SUVs, crossovers, minivans, and luxury models by a wide margin. Nearly one out of five American buyers believe that an affordable, mid-size sedan best fits their wide-ranging needs and lifestyles. With fuel costs rising, the mid-size segment is expected to experience strong growth.
Naturally, with such a large volume of cars sold, the competition is intense. There are more than a dozen worthy import and domestic brands and models striving to win the hearts and minds - and wallets - of mid-size customers.

While the original Mazda 6 won many faithful and passionate customers, a larger role is intended for its successor. The new 2009 Mazda 6 is aimed at a broader audience with the intention of offering the Zoom-Zoom experience to customers unaware of what they've been missing. The strategy is to move this vehicle to a distinctly different location on the premium versus sporty positioning map.

The strength of the 2003-2008 model was that its sporty design and demeanor exceeded the character of key competitors - Honda Accord, Nissan Altima, Toyota Camry. In other words, the original Mazda 6 was steeped in Zoom-Zoom spirit. This sets the stage for the new Mazda 6 to make its move into uncharted territory. This is the mid-size sport sedan that excels in both premium and sporty directions thanks to its exceptional quality, roomy comfort, high-performance powertrains, aggressive dynamic character, and distinctive appearance. Add to that evolved Zoom-Zoom. The Mazda 6 represents an evolution in how enjoyable a mid-size sedan can be.

THE NEW Mazda 6
While the fresh, attractive design and advanced features of the Mazda 6 are sure to attract a broad audience, this vehicle was designed and engineered with a sharp focus on specific types of customers. The following five profiles don't necessarily define the length and breadth of that constituent base but they do aid in understanding how the Mazda 6 differs from mainstream mid-size models:

The style-conscious individuals anxious to enjoy the Next New Thing. The new Mazda 6 is a trend-setter in several respects, not the least of which is its exterior design. This car is a striking standout at the leading edge of styling trends. The sleek and elegant curvature of the roof, for example, sets the Mazda 6 apart in the mid-size category.

The sophisticated consumers who treasure top-quality possessions. Mid-size car customers have high standards for creature comforts and attention to detail. Mazda is targeting those with highly cultivated tastes because they are less concerned about bargain-basement prices than they are interested in obtaining a carefully made, thoughtfully designed car capable of fulfilling their expectations.

Mature individuals with youthful tastes and attitudes. Age is no longer a trustworthy indicator of buying habits. The Mazda 6 will definitely appeal to customers belonging to all age groups with this common interest: owing a comfortable, attractive sport sedan that's uniquely entertaining to drive.

The hard-core drivers. Mazda's reputation for spreading its Zoom-Zoom sports-car spirit into every vehicle is well known. Driving enthusiasts who shop here are always well satisfied by Mazda's dedication to responsive handling, sharp acceleration, and all-around nimble behavior.

Mazda MX-5 Superlight Concept

The Mazda MX-5 Superlight Concept is an answer to the world of automobiles and individual mobility moving towards energy efficiency, environmental compatibility and uncompromised safety - along with dynamic attributes and driving fun. In its efforts to offer pure driving enjoyment, while meeting its ecological and social responsibilities, Mazda has been focusing on weight reduction as a core base technology. For 20 years, reducing weight has been a tradition with the Mazda MX-5. It provided the inspiration for the radical design of Mazda's latest show car and its radical interpretation of the cult roadster.

This year Mazda celebrates the 20th anniversary of the first Mazda MX-5 roadster, which laid the cornerstone for its Zoom-Zoom brand philosophy - reason enough for Mazda designers to create a fully-drivable show car, the Mazda MX-5 Superlight Concept. There are no plans to build this car, but it demonstrates how individual mobility can be maintained in a way that uses fewer natural resources.

Mazda's European R+D centre in Oberursel has created a show car that represents the essence of Mazda's fun-to-drive aspect. Based on the brand icon Mazda MX-5 Roadster, the Mazda MX-5 Superlight Concept is a pure, uncompromising two-seat sports car meant to be affordable to just about anyone. The main challenge for the design team in creating this roadster was "to evolve the MX-5, developed to perfection during the last 20 years, to a higher and extreme level," says Project Lead Designer Hasip Girgin. The result of their efforts is a roadster show car with an exciting design that is especially lightweight and distilled down to the very basics of sporty driving, that still manages to provide modern safety technologies. In an increasingly digitalized world, it creates a linear, direct bond between man and machine. Its conceptual purity means even better driving dynamics and fuel efficiency, which is accomplished by keeping the vehicle below the 1000 kg threshold. As a show car for lightweight construction and driving enjoyment, the Mazda MX-5 Superlight Concept is the ideal ambassador for Mazda's brand values.
Mazda MX-5 Superlight Concept

Exterior Design

The Mazda MX-5 Superlight Concept was to strengthen these bonds even further. By doing this without a windshield, the retractable top and its frame, designers achieved an important step in this direction. As the Mazda MX-5 Superlight Concept, the allweather production roadster has mutated into a driving machine that lets sports car enthusiasts enjoy the natural surroundings unfiltered and tangible. Not only does the wind blow unimpeded during driving, pilot and co-pilot can also experience the sounds, smells and temperature changes of their immediate surroundings. And finally, the show car's intense bond between the driver and the technology of the vehicle gives it a unique closeness that can only be found in stronger form in the cockpit of a race car.

Mazda designers created special roll-over bars, not only because they are very sporty-looking, but also to contribute to aerodynamic efficiency. These also make it clear that roll-over protection is important in this concept. And they prevent wind turbulence around the heads of the passengers, from whom the law would require the wearing of helmets while driving.

By removing equipment not vital to driving, and by replacing vital things with components that support the unique concept of the vehicle, designers sharpened the character of the Mazda MX-5 Superlight Concept.

Because there is no windshield, for instance, there is obviously no need for wipers. The roadster show car's completely open design makes the need for outer door handles, side windows and their openers unnecessary. A single, filigree aluminium, wide-angle mirror gives a good view of the road behind. It's placed inside an extension of the bonnet. Front and rear lights are the same as those of the production model with additional LED lamps at the front, and brake lights at the back of each roll-over bar, which contribute to the roadster's sporty look.

The lack of a windshield required an extension of the original aluminium bonnet into the cabin. The attached sheet here is made of lightweight carbon fibre and provides a hood for the dashboard frame.

This also changed the proportions of the body's design, making the front of the car longer and the passengers seem like they are sitting further back towards the rear-drive axle, all of which is enhanced by the massive roll-over bars and their aerodynamic cladding. The Mazda MX-5 Superlight Concept translates the dramatic proportions of historical race cars into a very modern form.

Interior Design

The purity in design of the exterior also characterizes the interior design, which does not have aesthetics as ultimate goal, but was conceived to contribute to reducing vehicle weight. Driver and passenger of the Mazda MX-5 Superlight Concept are greeted by racing bucket seats made of ultra-lightweight carbon fibre. They are slide adjustable and upholstered with the same saddle coloured leather as the armrests, the steering wheel, and the lightweight aluminium shift lever and hand brake. Colour-coordinated four-point seatbelts hold the driver and passenger firmly in their seats.

The bonnet extension into the passenger cell provides a canopy for the dashboard, which makes the dashboard look smaller than the production Mazda MX-5. Made of lightweight plastic reinforced with fibreglass, it contains the same instruments as the production Mazda MX-5. These are held in place by a dashboard frame made of lightweight carbon fibre. Like a purebred race car, the Mazda MX-5 Superlight Concept has an ignition button in the centre of the dashboard, along with two emergency kill buttons for immediate fuel and electricity cut-off.

Supplying air and climate control to the open passenger compartment is only possible in limited form, so the show car has no air conditioning and no fans. Air-flow is increased when the roadster accelerates, and only small air vents are needed. The interior is made without any trim. Sound insulation mats and rugs do not meet the requirements of a purist roadster like this and are not used at all.

Made of ultra-lightweight carbon fibre is the "floating-design" centre console with iPod® adaptor and the triangular reinforcements in the trimless doors. Driver and passenger can rest their arms here while driving.

Driving Dynamics

The Mazda MX-5 Superlight Concept is fully-drivable, but there are no plans to produce it in the near future. Under the bonnet is the cultivated and frugal MZR 1.8-litre four-cylinder engine paired to the production roadster's five-speed manual transmission. It develops 93 kW/126 PS of maximum power at 6,500 rpm. For an appealing engine sound, there's a Mazdaspeed cold-air intake made of polished and powder-coated aluminium and a Mazdaspeed exhaust system, both of them specific to the Mazda MX-5 Superlight Concept. These systems deliver more intake air-flow, and less exhaust-gas back pressure.

The engine sound is designed to suggest an engine with much higher displacement than the concept actually has. During charge cycles, a high-resonance bubbling sound in the muffler delivers the exciting sporty sound you expect from a very powerful engine.

The show car is designed to provide improved driving dynamics as well, and uses a four-piston, fixedcalliper brake system with perforated discs that, because of their size required an increase in track of 50 mm. A specially tuned chassis with a Bilstein® B16 coil-over suspension and Eibach® stabilisers give the body of the Mazda MX-5 Superlight Concept a ground clearance that is 30 mm lower than the production Mazda MX-5. Its sporty hydraulic power-assisted rack and pinion steering system is the same as that of the regular roadster. Its linear steering, coupled to a precise-shifting five-speed manual transmission with short shift travel, have contributed to the character of the world's most successful roadster for years.

Mazda 3 i-stop

The one way Mazda achieved this is to develop unique idle-stop technology that shuts down the engine when stopped in traffic jams and similar situations as a way to reduce fuel consumption.

The Mazda 3 will be powered by the MZR 2.0L DISI engine with green idle-stop technology - Mazda's unique i-stop system. Developed solely by Mazda, it is the world's only idle-stop system that restarts the engine using the remaining energy in the pistons (with a quick help of the starter motor) by injecting fuel directly into the cylinder and igniting it to force the piston down. The benefit of combining a DISI engine with i-stop (originally called SISS: Smart Idle Stop System) is that the system restarts the engine about twice as fast, and quieter, than conventional idle-stop systems.

Combining these two Mazda proprietary technologies and further measures like aerodynamic modifications, help the new Mazda 3 achieve approximately 14 percent lower fuel consumption (combined) than the previous Mazda 3.

When the driver stops the vehicle (red light, traffic jam) the engine stops automatically and sets itself to be ready for a prompt restart. As soon as the driver presses the clutch, the engine initiates the restart procedure automatically. This is a totally neutral operation for the driver.

The Mazda 3 i-stop Green Technology
When stopped at a traffic light or in a traffic jam, shutting off the idling engine can reduce fuel consumption by approximately 5 percent according to European city driving-mode tests. However, the drawback with conventional idle-stop systems is that they rely solely on the use of an electric motor to restart the engine. As such, they require a relatively long amount of time to achieve combustion in the engine when it restarts. In real-world driving, this means a lag between the moment the accelerator pedal is pressed down and the car begins to move, as well as vibration and noise.

The i-stop system for the new Mazda 3 leverages the DISI engine's direct-injection potential for improving fuel economy, restarting the engine quickly and quietly by injecting fuel directly into the cylinder and igniting it to force the piston down and set the crank in motion. The engine is controlled with precision to make this happen:

The Special engine requirements
In order to use combustion energy from the initial stage of restarting the engine, and to start the engine quickly, the following three conditions must be satisfied while the engine is stopped. (1) The engine must be able to inject fuel directly into the combustion chamber and ignite it; (2) an adequate amount of clean air must exist in the combustion chamber of the cylinder where the fuel is to be ignited; and (3) the computer control system must be able to determine which cylinder to fire immediately after starting the engine. The i-stop system, therefore, must use a direct-injection engine that can deliver fuel to the combustion chamber at high pressure, and that can easily ignite that fuel. Mazda's MZR 2.0-litre DISI petrol is the ideal engine to achieve this.

The Controlling piston position
The pistons are stopped in the appropriate position when the engine is stopped, an adequate amount of air is held within the combustion chamber, and the combustion chamber is properly scavenged to reduce the amount of unburned petrol. To this end, piston position is controlled by applying current to the engine's generator while the engine is being shut down. In doing so, it operates much like an electric motor, while using the signal from the crank angle sensor that monitors piston position as control feedback to stop the piston in the appointed position within its expansion stroke.

Special valve and crankshaft balance control
To scavenge the combustion chamber, the new Mazda 3 i-stop system momentarily opens the throttle valve slightly during the shut down process. (The throttle valve is normally closed when shutting off the engine.) Regular crank angle sensors are only able to determine forward rotation, which leaves them unable to monitor reverse rotation or to determine the correct piston position. Mazda's i-stop employs a crank angle sensor that is able to monitor crank rotation in both directions, enabling it to accurately determine the correct piston position. To maintain the proper crankshaft balance when the engine is stopped, it is rotated slightly in the reverse direction.

Faster restart + lower fuel consumption
These measures make it possible to properly inject fuel when the engine is restarted and control ignition advance, thereby allowing combustion energy to be used while the engine is stopped and to restart the engine in 0.35 seconds, roughly half the time required by conventional idle-stop systems. While Mazda's new i-stop system employs combustion energy to restart the engine, it is assisted by the starter for only the first few turns of the crank. This achieves the optimum balance between maximizing fuel savings while minimizing the amount of time required to restart the engine. As a result, it allows i-stop to reduce fuel consumption beyond what would be possible using combustion energy alone to restart the engine.

Th Driver support communication system
On the new Mazda 3 powered by the MZR 2.0 DISI engine, the i-stop system supports the driver by allowing visual confirmation of engine operation in relation to driving style. There is an i-stop on/off switch on the dashboard, and the driver cluster contains a light that displays "i-stop" when the system shuts down the engine in front traffic lights, for instance. When deactivated, an amber light shows that the i-stop system is not on.

Ensuring reliable operation
The new Mazda 3 i-stop system (only available with the MZR 2.0-litre DISI petrol) is equipped with an auxiliary battery that powers the system in the event that the main battery isn't properly charged or some similar problem occurs. This added control measure ensures that the driver can use the system naturally, without giving it a second thought. In addition, the system does not shut off the engine if the car is stopped on a road with an extremely steep grade, (greater than 14 percent incline).

Mazda Kazamai Concept

The interior - SUV Functionality with Driving Safety
The Mazda Kazamai is a pure expression of speed and power, it also accommodates up to four passengers with compact SUV comfort and functionality. It was designed to fulfil many driver and vehicle interfaces so as to support the driver in enjoying safe and stress-free driving, with a well considered man/machine relationship, good visibility and an easy to operate cockpit. This is one of Mazda's important areas of the Sustainable Zoom-Zoom plan.

The Lightweight and Aerodynamic
Weight reduction and superior aerodynamic performance are core technologies to improve both driving pleasure and environmental performance, especially improving fuel economy. Mazda will further focus on these crucial factors in order to achieve the goals of the Sustainable Zoom-Zoom plan. Despite its powerful exterior look, the Mazda Kazamai Concept's excellent aerodynamic performance is achieved through a flat floor panel, a rear diffuser, and a low roof line. The aim was to make the Mazda Kazamai's aerodynamics more than 10% better than other vehicles in its class.
When Mazda set about reducing the bodyweight, they leveraged CAE applications and focused on four major areas: collision safety, handling, NVH, and strength. At the same time, lightweight materials and new processing/joining technologies were put to effective use. Aluminium or aluminium-alloy is used for the bonnet, chassis and engine block. The designers aimed to make Mazda Kazamai 100 kilograms lighter than similar models by employing plastics for the panels, fenders and the engine cover. These features also contribute to advanced handling and improved fuel economy and CO2 emissions.

Next-Generation Powertrain - 30 Percent Improvement in Fuel Consumption
The ideal powertrain match for the Mazda Kazamai Concept would be the next-generation 2.0-litre direct-injection petrol engine, which Mazda engineers are currently developing. This engine delivers a balance of sporty driving - especially in a compact car like the Mazda Kazamai - with good environmental performance. Mazda Kazamai will feature a DISI engine based on the current Mazda CX-7's engine, with advanced technologies to minimise energy loss and vastly improved thermal efficiency. Mazda's next generation 2.0-litre DISI petrol engine also has combustion control technology and variable valve control that deliver strong torque throughout the rev-range for excellent engine response as well as superior fuel economy. A next-generation catalyst also ensures superior emissions performance.

The engine is coupled to a lightweight, next-generation compact six-speed automatic transmission that is highly responsive and delivers the direct feel of a manual transmission, and with four-wheel drive for superior traction. In combination with Mazda Kazamai's next-generation aerodynamics and its lightweight body outlined above, this powertrain would deliver an estimated 30 percent improvement in fuel consumption and emissions (versus the current MZR 2.0-litre petrol) - without compromising driving pleasure.

The Advanced Safety and Security : Mazda Kazamai is lightweight, fuel-efficient and fun-to-drive, it is designed with safety as a key element. Its advanced body shell is a product of a new body structure programme currently being refined at Mazda with a lightweight structure that provides high levels of crash safety. Mazda Kazamai also has a long list of active safety features including roll stability control, blind-spot monitoring to assist lane change, a pre-crash safety system and advanced dynamic stability control (DSC). And to meet future pedestrian safety requirements, it has soft plastic fenders and a shock-cone aluminium bonnet that is very efficient in absorbing impact energy.

onboard the Mazda Kazamai is a personal security system. This advanced system monitors the area around and inside the car, and has an automatic alert system which informs the driver in the event of an emergency to help to protect both the owner and occupants.

Mazda Kazamai Concept

Mazda Kazamai Concept

Mazda Kazamai Concept is dynamic and athletic looking on the outside and displays an evolved Mazda Nagare 'flow' design. Unlike previous concept cars, Mazda Kazamai's styling represents powerful natural movements that are emotionally expressed through three-dimensional motifs stretching over the whole body, representing a fusion of design and functionality.Mazda Kazamai is an impressive combination of packaging requirements and design aesthetics. With a width of 1,930mm and a length of 4,520mm, it is slightly larger than the current Mazda3, with room for SUV comfort and functionality on the inside. Yet, because it is only 1,500mm high, has a flat roofline and very short rear overhangs, it also has a sporty coupe look with the promise of driving fun.
The innovative body design features flared fenders that emphasise SUV-like strength and a cabin befitting a sports car. The wedge-shaped profile was designed to evoke the image of a sleek arrow cutting through a mighty wind. In particular, the body design between the front wheel arches and the roof pillars is intended to express the agility and dynamism of wind gusting along the side of the vehicle. The panel lines on the sides represent swift and elegant crosswinds, further accentuating the dynamic and stylish body design. The bonnet itself is lower in the centre than at the sides, which emphasises the car's powerful front fenders that accommodate large, 22-inch diameter wheels with 265/45 R22 tyres.The five-point Mazda grille is integrated into the body to create a clean and light image which, together with the flared front lower sides, contributes to excellent aerodynamic characteristics. The aerodynamics are further improved by making the air intakes as small as possible. The side sill panels and rear combination light covers also help to control the wind flow and reduce drag even further.

Mazda: Kiyora Concept

The Mazda revealed the direction its new technology development would take when it announced the Sustainable Zoom-Zoom plan in 2008. In line with this plan, Mazda is focused on making cars that achieve harmony between Mazda's hallmark driving pleasure and environmental and safety performance. Mazda Kiyora demonstrates how Mazda will achieve a 30 percent improvement in fuel economy in the near future and introduce new vehicles that are exciting to look at and drive. Featuring next-generation environmental technologies, Kiyora was envisaged as a fun and cool concept for young European urbanites, and one that only Mazda could produce.

Mazda Kiyora gives an indication where Mazda could go with a small, eco-friendly city car in the near future. It is highly fuel efficient, with a very small CO 2 footprint, delivering Zoom-Zoom driving fun and high levels of safety. The car achieves this by taking Mazda's acclaimed lightweight strategy to a new level by employing an extremely rigid and lightweight carbon-fibre body structure beneath a small, aerodynamic outer skin and a spirited, small-displacement 1.3-liter direct-injection engine. Mazda Kiyora also features Mazda's unique Smart Idle Stop System (SISS) and a newly developed six- speed automatic transmission with direct feel and fuel efficiency similar to that of a manual. With these technologies, the Mazda Kiyora concept would produce CO 2 emission of under 90g/km.

Themes for the Mazda Kiyora concept include cleanliness, health and safety. These key aspects are essential for young city dwellers as well as any compact car in the current global environment. The concept was based on Mazda's sustainable technology vision, which aims to ensure customers can continue to enjoy a Zoom-Zoom experience in the future. Water was also selected as a theme for this concept, due to its association with the aspects mentioned above, and the car was named Kiyora (meaning 'clean and pure' in Japanese) to reflect this. It features next-generation technologies clothed in a friendly and cool design that is as functional as it is beautiful. This is the first concept to express Nagare 'low' in the patterns and colours of water.
Defining the Concept, "Urban Hub" - Advanced Product Strategy

Mazda Kiyora is a redefinition of the small coupe and is dedicated to embody the same fun-to-drive nature as every other Mazda vehicle, combined with innovative ideas that minimize its impact on the environment. This concept is the translation of Mazda's Sustainable Zoom-Zoom philosophy into a lifestyle vehicle for progressive urbanites.
The idea for this car was born from research that identified market opportunities to address future unmet customer needs with innovative concepts and ideas. The very first step taken by Mazda Motor Europe's Advanced Product Strategy (APS) team was an in-depth analysis of the small city car segment in Europe. Having defined several potential customer profiles in this segment, the team focussed on the urban customer with a post-modern lifestyle.

APS found that exterior styling, compact size, manoeuvrability and flexibility were just as important to these young people as high fuel efficiency. European urbanites, then, will continue to commute and use their cars in the city of the future; but they will expect them to use less fuel and produce fewer toxic emissions, while still being fun to drive, easy to park and use. To achieve this, the vehicle must be lightweight and small. Kiyora is even smaller than the new Mazda 2. Reducing vehicle weight is a key concept that is crucial to achieve the goals set out in the Sustainable Zoom-Zoom plan. Kiyora takes Mazda's 'gram strategy' — that has been used previously to produce new vehicles, all of them lighter and more fuel eficient than their predecessors — to the next level. It should also be flexible, a kind of 'urban HUB' that would allow you to go to university during the day, go shopping in the early evening, and take three friends clubbing at night before driving home, thanks to its lexible interior that can be used as a two-seater with boot, or as a 2+2 seating arrangement. The car should have a next-generation cockpit and be fun to use on a daily basis. And it should be safe and environmentally friendly.

Zoom-Zoom Experience and Environmental Performance Mazda Kiyora supports the active lifestyles of young people with its agility, cleanliness, and excellent economic performance. Mazda's next-generation 1.3-litre DISI petrol engine is an evolution of technologies used for the 2.3-liter DISI petrol engine that currently powers Mazda's sports crossover SUV, the Mazda CX-7. Improved direct- injection technology and newly designed combustion chambers enable more precise ignition control. The engine's efficiency is increased by a combination of advanced dual sequential-valvetiming (S-VT), variable-valve timing and lift mechanism, and optimal valve control. The engine is spirited as well as clean and efficient and, in combination with a compact and lightweight six-speed automatic transmission with manual shift control, it would make Mazda Kiyora powerful and cultivated, even at low engine speeds. In stop and go urban traffic conditions, Mazda's newly developed Smart Idle Stop System (SISS) would save fuel by automatically shutting down the engine when the vehicle is stationary, and achieves a quick and quiet restart for stress free driving. The system injects a small amount of fuel directly into the engine's cylinders and ignites it to generate downward piston force which, with the aid of an electric motor, rapidly returns the engine to idle speed. Emissions would be among the lowest thanks to a new catalyst that more effectively removes harmful exhaust materials by employing single-nanotechnology to control catalyst particles that are smaller even than those controlled by conventional nanotechnology. Combined with reduced weight and improved aerodynamics, these insightful technologies would result in CO 2 emissions of 90g/km or less.

Exterior - Fusing Form with Function
"Mazda Design has been working hard over the past two years to develop an exciting new design message with its Nagare series," says Peter Birtwhistle, Chief Designer, Mazda Motor Europe. "Mazda Kiyora is the latest iteration of that philosophy."
The Mazda Kiyora concept car is formed in the shape of a water droplet on its side, as are its two side windows. Its diminutive size and low roofline give it a small front cross-section. This is combined with an elaborate underbody that controls wind swirl, a rear roof spoiler, and specially sculptured body lines for a highly aerodynamic form with a coefficient of drag that is over 10 percent lower that of the current Mazda2. This outstanding fusion of engineering and the Nagare design was a key target.
"The architecture of the car has been rethought," says the concept's lead exterior designer, Mickael Loyer. "The main structure of the car is an 'in and out' frame, like a shell that protects you from the outside environment, and lets you be opened and linked to it at the same time, thanks to the transparency of the top and the side windows, which also gives a lightweight feeling."

About 10 cm shorter than the new Mazda2 sub-compact, Kiyora is also an environmentally friendly city car that is cute and agile, and invites you to climb in for a ride. It uses a soft design language and lowing lines, while retaining an overall style that is really expressive and sporty. Here is the expressive five-point grille first used on the Mazda Sassou concept three years ago - backlit when the car is on with soft, red lighting - but now further developed with Nagare low lines that are carved and more three-dimensional. They are formed to guide air into the interior of the car without the use of fans, which saves weight. Its silhouette features character lines that are sleek and smooth, and move upwards and rearwards, fusing into the rear spoiler. Combine it all with 18-inch alloys and extremely small overhangs, and you have a truly sporty look in a small package.
Though small, Mazda Kiyora has a rear boot big enough to carry a large suitcase, a briefcase and a notebook. It is accessible via a liftgate that opens very high (with a low load floor level) for easy loading and unloading, and it's flexible. When the rear seats are not in use, you can push your luggage forward and stow even more, while the strong yet flexible seat material stretched over the seats holds the luggage in place. This system also has the advantage that it hides whatever is stored in the boot from prying eyes outside the car.

The roof of the new Mazda Kiyora is another example of how Mazda designers were able to combine functionality and design aesthetics. It is transparent, for an open-air feeling on the inside, and has photovoltaic solar cells which provide electricity for the car's interior systems.
"Kiyora is about water fluidity and transparency," says Mr. Loyer. "It's all about layers of perception. You start with a shape and there is a shape behind and another one behind that. It's like water; the deeper you go the more details appear. Nagare low here has different layers lowing into each other. Repeated layers lead you into the car. And because the inside of the car is visible, it becomes part of the exterior design."

The doors and side windows of Mazda Kiyora are fused into a single unit and function as both. These 'windoors' are made of plastic, which provides the same transparency and refraction properties as glass, and the strength of a thin-panel door, but with far less weight. They are also easy to use and practical. Touching the surface of the front tip of the door activates a sensor, which opens the doors up and away from the car, a plus when parking in tight city spaces. They also allow a view into the interior when the doors are closed. But looking into Mazda Kiyora is more than just looking through glass.
"Using various layers of materials, combined with forms and colours on the inside, gives the impression of looking into water with its depths and lowing shapes below the surface," says Luca Zollino, who assisted Mr. Loyer in creating the exterior. "For instance, there is a body shell side member shaped like sea grass that is visible just behind the surface of the doors and, when you look deeper into the car, there are the lowing shapes of the dashboard and centre console."
The design of the wheels also supports the water theme. Its front spokes are convex and shaped like the blades of a boat propeller, while the concave back spokes are joined to the wheel rim and have a reinforcement that seems to grow out of the spoke itself. Kept very smooth, the wheels of Mazda Kiyora give a twirling, twisting surface articulation.

New Liquid-Skin Display IP Concept
This display would be a simple yet very practical type of instrument panel that uses advanced touch-screen technology with tactile feedback. Using liquid-skin display technology, it would mimic the rippling that water makes when you touch it with your finger. When the car is off, the IP looks like ice, frozen and hard. When the car is switched on, the display appears to turn into water. Information icons would appear and float downwards to pre-programmed positions in front of the driver. The driver would be able to move the icons around with his finger and could even organise them however he wished. He could lip through menus, select settings for temperature, and even send an email.

"We call Kiyora's IP a liquid-skin display," said Gergory Vera, who designed the interior, "because it is conceived to ripple like water when you touch it. Icons bounce off each other as if they are floating in water. This would be a logical next step in intuitive-feedback, flexible-screen displays and is a natural and easy way to operate the systems of a car."

From this touch-screen display, you could also control a hard-disk drive with advanced sensors that would provide environmental information like how much fuel you used and how many grams of CO 2 you released into the atmosphere on a particular day. It could also calculate how many toxins the car filtered out of the air and water during the same period.

Considerations for the Cabin Environment

Mazda Kiyora concept would be able to filter out toxins from the outside air and use it inside the car. The right side of the dashboard consists of a large, single piece of thick activated carbon, which is a natural resource that has been used for centuries in Asia as a purifying material. The above-mentioned Nagare low lines at the front of the car guide outside air into the car and through this charcoal, which filters out and captures toxins better than most filter systems, without the need for an electric fan or inorganic materials. Taking advantage of rain as a natural resource the roof of the Mazda Kiyora channels rainwater firstly through an activated carbon filter and then into a specially commissioned drinks bottle designed for Mazda by LIFESAVER® systems. The LIFESAVER® bottle citi™ is located between the front seats for easy access, and uses state of the art ultra filtration hollow fibre membranes. With a pore size of 15 nano-meters these membranes remove microbiological contamination including bacteria and viruses without the aid of chemicals, delivering safe fresh drinking water to the user any time.

The bottle is removable so can be taken out of the car and used to gather water from other natural sources such as rivers, lakes and streams.

Colours and Materials - A Triumph of Material Engineering Mazda Motor Europe's Colours + Materials team has distinguished itself in the development of new kinds of materials for its concepts. In Sassou, it was translucent plastic treated in a way to match the body colour and to hide light effects, and in Hakaze it was the brilliant use of surface textures that mimic the feel of natural materials. With the Mazda Kiyora, the colours and materials team faced its greatest challenge yet - to express the theme of 'pure water' in visible and touchable ways.

"Based on the extreme requirements of Kiyora, as a new eco-friendly car with a fully lexible interior, we needed to research in unusual fields," said Maria Greger, Senior Designer at Mazda Motor Europe and head of the Colours + Materials team. "We looked for materials and processes that are not yet used in the automotive industry. We had to find materials that not only work in covering parts, but are directly related to function. The best example is the material used for the floor and rear seats. This is the same textile, but treated differently to best adapt to the function it needs to fulfil."

The exterior of the Mazda Kiyora is blue-green and has transparent, polycarbonate doors, chosen to underscore the purity of water. On the inside you can see forms - like the wavy side member of the body structure - that look like lowing sea grass. These were given a colour scheme that, when seen through the doors from outside the car, makes it seem as though you are looking into water.

"We chose bluish and greenish colours, which is colour of water," said Luciana Silvares, Senior Designer at Mazda Motor Europe. "The deeper you go, the deeper the colour of water gets. We wanted to give this car the feeling of water and ice, sea or lake (from the surface to depth), showing transparency and gradient."

The interior is a masterpiece of materials engineering. The body shell is visible, like an inner skeleton, and supports the water theme with its wavy, lowing shapes, while functioning as a true body structure. And the interior has a colour scheme that makes the front seats seem to float above a floor that looks like frozen water. For the instrument panel and door inners, soft coatings and light metallic effects are employed to enhance this impression.

The rear seats are one of the concept's most interesting features and a perfect example of how to combine material and design to express the theme of water, while saving weight and losing nothing in functionality. They are made of only two components: a seat skeleton that is part of the body structure at the back of the cabin, and a flexible and robust textile stretched over this. This textile allows a person to sit down into the seat and acts as a irm surface to sit on like a lawn chair, and then to spring back to its original shape when the person leaves the car - effectively hiding the seats. This 'hidden seat' is designed for short trips in town, and is far lighter than traditional car seats.

"The material for the rear seats is an extremely stretchable textile that we developed with the Company Straehle und Hess," said Ms. Greger. "It is made of knitted polyester that has the ability to return to its original shape. With a special construction of two laminated layers, this material is, despite its extreme stretch ability, also extremely stable."

The rear seats also work in conjunction with the floor to contribute colour-wise to the overall theme of pure, watery depths. Both the seats and the floor are made of the same materials, but treated differently to maximise their functionality. Two-dimensional printing was employed for the colours and sea grass graphics on the seats, and a unique, three-dimensional (3D) casting process was used for the floor surfaces. The 3D casting process was inspired by the PU micro-injection printing process used on textiles for sportswear. This allowed the team to give the floor surface the durability and abrasion strength needed to function as a real floor, and to create the image of deep and layered surface to express the image of water and ice.

Interior Design - Visualised 'Nagare' Design and an Expression of Lightness

The interior shapes not only provide aesthetic motifs, they also function to stiffen the passenger compartment with minimal weight. Mazda's strategy of shedding excess grams wherever possible in its production cars was taken to a new level in Mazda Kiyora. The visible body structure is a real structural element of the car - stiff and crash-resistant. It is indicative of Mazda's approach to conduct a thorough structural analysis to solve complex issues such as safety and rigidity requirements instead of simply replacing materials with more expensive ones. The rear seats that are integrated into the body framework are also examples of this approach. Lightweight materials such as aluminium and a special resin foam, which is under development at Mazda, would be used not only for interior parts such as the instrument panel, but also for the bonnet, tailgate and sections of the chassis. Their effective usage contributes to improving the yaw moment of inertia and reducing the unsprung mass, and leads to superb handling.

The Mazda Kiyora concept has interior shapes that express Nagare 'low' by looking as though they are floating in a current of sea water that is moving from front to back. The instrument panel starts at a single point and lows around the driver and to the right of the front passenger as if it were several blades of sea grass growing out of a rock underwater. The front seats seem to float above the floor, and the arms of body structure twist like sea weed at the sides and top of the cabin. As well as being an integral design element, the door structure also functions as a side member and, in combination with the side sills, would effectively protect occupants in the event of a side impact.
"Rapid prototyping was used for most of the natural shapes," says Jo Stenuit, Assistant Chief Designer and Project Leader. "We have a very natural design with complex lowing shapes. Normal moulding processes would not have allowed us to produce such elaborate designs."
