Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Chevrolet Volt was introduced in the 2011 model year. The car is a plug-in battery-electric/gasoline hybrid, featuring an electric-only mode with a range of 35 miles for 2011 models according to the EPA. After the electric-only mode ends, the gas engine kicks in to power the vehicle. Estimated gas mileage in this mode is listed in the specifications below.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints and dummy kinematics

Dummy movement was well controlled. The driver side curtain airbag deployed during the crash. After the dummy moved forward into the frontal airbag, its head contacted the side curtain airbag.

The Chevrolet Volt was introduced in the 2011 model year.

After the electric-only mode ends, the gas engine kicks in to power the vehicle. Estimated gas mileage in this mode is listed in the specifications below.

Injury measures

Driver — Measures taken from the dummy indicate that rib fractures would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.

Passenger — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof and a side airbag that deployed from the seat.

Passenger — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
