Vehicle Outline

Exterior design

•  Fun-to-drive with instinctively attractive styling

―  4SD

•   Dynamic and elegant sport styling has been achieved due to the fused form of the bonnet and compact cabin.

―  5HB

•  Advanced styling has been achieved due to the continuous form of the bonnet and body, and the flared fenders accentuating the body.

Interior design

•  A comfortable interior and sporty design incorporating Mazda’s inherited DNA

―  A simple, clean-cut dashboard with a spacious feel has been adopted.

―  An instrument cluster with an emphasized sportiness has been adopted.

―   Illumination that is both easily visible and comfortable for the eye has been adopted.

•  Interior space that fits four adults comfortably

―  An interior space that is surprisingly larger than thought when viewed from the exterior has been achieved due to the adoption of a long wheel base and elongated body.

―  An auto-light system that allows for constant visibility of the vehicle’s immediate surroundings has been adopted.

―  A full-auto wiper system allowing the driver to concentrate in any weather condition due to the steering wheel-integrated control has been adopted. This system features a rain sensor on the windshield which determines the rainfall conditions and automatically adjusts wipers to the optimal speed.

•  Storage spaces that are spacious, simple and highly functional

―  Front seat storage has been improved due to the adoption of a large glove compartment that can hold items such as a PET bottle or a small backpack, and featuring a lid that can hold a tissue box or other small item.

―  A double-layered center-console box with an upper tray that can hold mobile telephones and other small-sized items has been adopted.

•  Luggage space

―  The luggage area size is class-topping in terms of area and features clean, nearly flat surfaces due to the under-floor positioning of the coil springs.

―  4SD

•  Double-link hinges for the trunk do not interfere with or damage luggage during loading/unloading.

―  5HB

•  A storage space is provided under the floor.

•  A flat luggage space is achieved by folding the split rear seat backs forward.

Engine

Gasoline engine

•  Mechanical

―  ZJ (1.3 L), ZY (1.5 L), Z6 (1.6 L), LF (2.0 L), L3 (2.3 L), L3 Turbo (2.3 L with turbocharger) engines have been adopted.

―  Due to the adoption of direct injection and the turbocharger, high output and fuel economy at low to medium engine speeds have been achieved. (L3 Turbo)

―  Variable valve timing that optimally adjusts valve timing in accordance with driving conditions has been adopted to all engines.

•  Intake-air system

―  With the adoption of the variable valve timing system to all engines, which controls intake valve timing in accordance with driving conditions to attain highly efficient air charging, engine output is improved at all engine speeds.

―  An electronic throttle valve has been adopted for all models resulting in precise intake air control.

―  A turbocharger has been adopted, largely improving engine output. (L3 Turbo)

Diesel engine

•  MZ-CD 1.6 (Y6)

―  Diesel particulate filter systems have proved to be an effective means of reducing particulate emissions (High power-Euro 4).

―  The common rail injection system is a pressure accumulator injection system. This means that with this system the fuel pressure is constantly present, whilst on conventional systems (for example with the distributor type fuel injection pump), the fuel pressure always has to be generated for each injection process.

On the common rail injection system, therefore, pressure generation and fuel injection are separated. The injection pressure is, to a great extent, generated irrespective of engine speed and injected fuel quantity and is made available in a common rail ready for injection.

―  Advantages of the common rail injection system are:

•  high injection pressure up

•  injected fuel quantity, fuel pressure in the high pressure accumulator (rail) and start of injection all matched to the operating conditions

•  variable pilot injection to optimize combustion quality

•  advanced post injection to raise the exhaust gas temperature during the regeneration process of the diesel particulate filter (High power-Euro 4)

•  retarded post injection to raise the exhaust gas temperature during the regeneration process of the diesel particulate filter (High power-Euro 4)

•  low tolerances and high precision over the entire service life

•  MZR-CD (RF Turbo)

―  The following improvements have been realized due to the adoption of the common rail type fuel injection system.

•  Particulate matter (PM) reduction has been realized due to the extremely high pressure fuel injection system.

•  NOx and PM reduction have been realized due to an optimized combustion condition and enhanced flexibility in injection volume, timing, and pulse

―  A diesel particulate filter system has been adopted to remove particulate matter (PM) in the exhaust gas.

Suspension and steering

•  Front suspension

―  A strut-type front suspension has been adopted.

―  Due to the tight connection of the four-point rubber mounts to the body, high handling stability and improved riding comfort is provided together with low NVH (Noise, Vibration, Harshness) with no loss of mount rigidity.

•  Rear suspension

―   An E-type multi-link rear suspension has been adopted.

―   A wider luggage compartment is ensured due to the separated positioning of the shock absorber and coil spring.

―  Also due to the separated positioning of the shock absorber and coil spring, side force on the shock absorber is reduced so that the suspension system operates smoothly and riding comfort is improved.

•  Power steering

―  Engine-speed-sensing power steering has been adopted for vehicles with the ZJ, Z6, L3 Turbo engine, MZR-CD (RF-Turbo) engine.

―  For vehicles with the LF, L3, ZY, MZ-CD 1.6 (Y6) engine, excellent steering feel and smooth handling from low to high speeds is provided due to the adoption of Elector Hydraulic Power Assist Steering (EHPAS). Engine load is reduced, improving fuel economy, due to the adoption of an electric power steering oil pump.
