The Volt is a little soft off the line, as it overcomes its nearly 3800 pound curb weight (3781 lbs., to be exact). Target Speed: 65 MPH (when permitting), A/C on low, windows up: 44.2 MPG.Target Speed: 68-70 MPH (when permitting), A/C on low, windows up: 41.5 MPG.Our test unit was equipped with the identically-sized polished aluminum wheels.

The test vehicle was delivered with slightly over 5000 miles on the odometer. Temperatures spanned the fifties through the eighties, with Interstate highway testing temperatures running near the top of that range. The Volt turned in a very respectable 42.9 MPG in our Interstate test in late-spring/early summer temperatures. So we ran down the Volt’s battery, took to the highway for a long-distance test, and were not disappointed. Fuel-efficiency out on the open road was the big question. While rolling up close to 600 miles on our Viridian Joule Tricoat review unit, it soon became clear that the 35 mile range is conservative when the Volt is driven conscientiously. The official fuel economy estimates for the 2011 Chevy Volt are different from what we’ve long been accustomed to, with 93 miles per gallon (MPG) combined and 37 MPG in gas only mode. When the battery is depleted, the Voltec system’s range-extender kicks in to provide electricity. With a full charge, the Volt’s EPA (city) electric range is 35 miles. A 1.4-liter inline four cylinder engine and 55 kW generator motor are used as a range-extender. The game-changing 2011 Chevrolet Volt is equipped with a 111 kW electric drive motor that produces 149 horsepower (HP) and 273 foot pounds of torque. If you should exceed the Volt’s range before recharging, a fuel-efficient gasoline-powered engine will kick in to provide electricity to power the electric motor. Top off the battery overnight and you’ll have approximately 40 miles of pure electric range in the morning. ![]() MPG-o-Matic 2011 Chevrolet Volt Review Summary: The 2011 Chevrolet Volt is both futuristic and familiar, with a range-extended Voltec drivetrain designed to provide efficiency, as well as flexibility.
