Mazda‘s upcoming SkyActiv-G engines will get a 14:1 compression ratio, the highest in the world for a gasoline engine, according to a report in Autoweek.
Most cars run compression ratios of 8.5:1, with high performance engines using ratios closer to 11:1. The SkyActiv-G motor takes that figure to a new level, and we’d really like to know how Mazda did it. High compression motors tend to allow for greater efficiency when it comes to making power, but too high of a compression ratio can make the engine more prone to going ka-boom.
Together with new transmissions, diesel engines, rigid chassis and weight reduction in all aspects of the car, the next-generation of Mazda’s should be pretty solid cars. Too bad they’re a few years away from hitting the market.
