I found this and thought I would share:

"
And the Volta's 408-hp Hybrid Synergy Drive® (a 3.3-liter V6 with an electric motor for each axle) not only delivers 435 miles on a 13.7-gallon tank, but 0-60 acceleration in a mere four seconds."
Impressive numbers. It's a looker to. The mileage works out to 31.75 miles per gallon. Not bad for a car that has a 0-60 time of 4 seconds.
