Let's not overlook the other option (aside from gas-electric hybrids) for fuel efficient cars that is also getting more play in Motown these days. At the NAIAS earlier this month, five automakers said they would introduce new diesel engine vehicles, according to Automotive News.
But even better news came from Ford, which showed off the Reflex concept car that integrates a diesel engine and electric motor. Mercedes is also working on a diesel hybrid.
Automaker's interest in Integrating diesel and hybrid technology makes sense because as I predicted 15 months ago, the technologies are extremely complimentary. The electric motor assist helps in acceleration and provides a battery only option at high speed, while diesel engines are more efficient than gasoline engines at hauling or maintaining highway speed.
Many city buses and locomotives take advantage of the diesel-electric technology today.
In France, Citroen will announce a diesel-electric hybrid later this month for sale by 2010.
Yes, there are still issues about cost and meeting the emissions standards, but expect more diesel hybrids in the coming years.
