2011 Chevrolet Volt 4dr Hatchback (gas/electric hybrid DD)
I have owned my Volt since mid-March, and have used exactly 20 gallons of gas over 3100 miles.
Most of my daily driving is done in all electric mode, but I did take one 80 mile trip and one 750 mile trip.
On the long trip I did not recharge and averaged 41 mpg in charge-sustaining mode.
I also own a Prius and feel that the Volt, though a bit smaller, is a big leap forward over that fine car.
The Volt is quicker, handles better, is quieter, has much lower operating cost/mile (i pay only $0.10 per kWh), and has been totally glitch free.
It's an astonishing achievement.
equivalent gas mileage near 100 mpg, very comfortable seats, great sound system, and a feature set that rivals many luxury cars.
