Mazda Ibuki Sports Car Concept | Part Two

Mazda Ibuki Concept


Advanced Safety

The super front-midship layout assures an adequate crushable zone, making a significant contribution to safety including the protection of pedestrians in accidents. A four-point active roll bar has been installed to improve safety. Under impact the active roll bar instantly lifts up via sensor control to reduce occupants’ injuries in the event of a roll over.

Powerful LED headlamps give improved visibility, and a keyless entry by ID card is provided.

Balanced, responsive engine

The Mazda Ibuki is powered by a new, lightweight and compact 16-valve MZR 1.6-litre inline four-cylinder engine equipped with sequential valve timing and lift for both intake and exhaust valves.

The engine also features an electric hybrid motor boost acceleration from standing start and partly controls engine vibration. When the car is stationary, the hybrid motor automatically stops the engine to save fuel and reduce emissions. During deceleration the hybrid motor functions as a generator, using regenerative braking to recharge the battery.

Mazda Ibuki features a six-speed manual transmission with a decisive yet smooth shift feel thanks to reinforced synchronisers.

Strong body structure and ultra-lightweight design

Mazda engineers developed a twin backbone body structure for Mazda Ibuki, based on the high-mount backbone frame concept employed with Mazda RX-8. This unique construction helps achieve extremely high rigidity, a level of stiffness comparable with a closed body structure.

Practical use of lightweight materials placed at key strategic points keeps overall weight down and recyclable materials were used wherever possible.

Independent left/right rear-mounted air conditioning system

Mazda engineers located the air conditioning system behind the seats allowing the engine to be mounted much further to the rear and enabling improved independent left/right zoning. Spot-cooling zones provide cool air during summer, while a heating zone traps warm air between the occupants ensuring a comfortable cabin environment during open-top driving even on the coldest of days.

In addition, a new audio system that combines the seat air conditioning ducts and speaker in one, delivers much clearer sounds.
