Gasoline engines are getting better and better. Have you seen some of Mazda's latest engine innovations? Emissions have been improving rapidly, and fuel economy has been improving too (unfortunately these gains have been hidden by increasing size and curb weight)
- mkirklions 8y agoIs this a result of American regulations and competition?
- gascan 8y agoYes and yes, I believe. American regulations on emissions have been tightening, which (as one of the largest markets) drives requirements. Also, Mazda is one of the smaller fish, so they have to innovate to stay competitive.
- rconti 8y agoAmerican and Euro standards both. And yeah, Mazda's really been pushing the limits of high compression ratios and alternate cycle engines.
