New Hybrid Cars for 2011

Porsche Cayenne S
Dispensing with tradition, Porsche has begun selling a hybrid version of the Cayenne S, which it claims can accelerate from 0 to 60 m.p.h. in 6.1 seconds and travel 150 m.p.h. on a test track, while getting an estimated 21 to 25 m.p.g. It can drive on electric power at speeds under 37 m.p.h. and isn't subject to any kind of gas-guzzler tax even though its gas-electric power train can produce 380 horsepower. Its base price is $67,700.
