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.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 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.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.
