It is all about fuel economy right now, and the automakers are pulling out all the stops to ensure they might weather the stiffening CAFE standards in the coming years. Electric cars, hybrids, plug-in hybrids, diesels… all are about to become a lot more commonplace. Yet, still, there remains a seat at the table for fuel-efficient combustion engines, and there is plenty of room for improvement in the old standby.
Forgoing much of the hybrid craze, Mazda is focusing on clean petrol and diesel engines. And their work has not gone unrewarded. Comments from spokesmen suggest that the compact Mazda3 with a SKY-G engine got around 40 mpg on the highway. Not too shabby!
