Audi Q7 Hybrid
Launched as a concept in 2005, the Audi Q7 Hybrid looks to be on sale this year. The electric motor helps the 4.2 liter V8 make 148 pound-feet more torque and shortens acceleration to 62 mph from 7.4 to 6.8 seconds.
Everything else is pretty hum-ho, but the Q7 Hybrid's roof solar panels allow air-conditioning to run when the car is off, a trick feature all dogs should love.(Audi AG)
