Mazda announced that their latest generation Demio (aka Mazda 2) gets much better fuel economy than hybrids.  That mean no more expensive batteries to replace.

The Demio’s engine has uniquely shaped pistons to increase combustion efficiency, and, it has a computer that will shut off the engine when it’s idling beyond a certain time limit.

The Idling Stop System will automatically start the engine when you’re ready to go.

Mazda’s Chief Executive, Takashi Yamanouchi, says how well the car sells will determine the future of car design for Mazda.  He hopes that all Mazda cars will be produced with similar technology within five years.  No word on if the new gas saving Demio (Mazda 2) will be sold in the United States.
