Arlington, VA - The Chevrolet Bolt is the first all-electric vehicle to earn a 2017 "Top Safety Pick Award" from the Insurance Institute for Highway Safety.

To qualify for 2017 TOP SAFETY PICK, a vehicle must earn good ratings in five crash-worthiness tests — small overlap front, moderate overlap front, side, roof strength and head restraints — as well as an advanced or superior rating for front crash prevention  system with a superior or advanced rating. Vehicles that meet those criteria and also have good or acceptable headlights earn TOP SAFETY PICK+.

The small car is new for the 2017 model year. Unlike the Chevrolet Volt, it has no back-up gas engine.

The Bolt earns good ratings in all five of the Institute's crashworthiness tests — small overlap front, moderate overlap front, side, roof strength and head restraints. It also has an optional front crash prevention system that earns a superior rating. The car avoided collisions in IIHS track tests at 12 mph and 25 mph, and the system has a forward collision warning component that meets National Highway Traffic Safety Administration criteria.

The Chevrolet Bolt was introduced in the 2017 model year. The car is a plug-in battery-electric vehicle with no gasoline or diesel engine to help power the car. The EPA city and highway values listed below are based on a comparison of the energy content of a kWh of electricity vs. a gallon of gasoline.

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. As the dummy moved forward into the frontal airbag and during rebound, its head also contacted the side curtain airbag.

The Chevrolet Bolt was introduced in the 2017 model year. The car is a plug-in battery-electric vehicle with no gasoline or diesel engine to help power the car. The EPA city and highway values listed below are based on a comparison of the energy content of a kWh of electricity vs. a gallon of gasoline.

Structure

The driver space was maintained well, with maximum intrusion of the lower interior of 12 cm at the lower hinge pillar. Upper interior intrusion measured 7-8 cm at the hinge pillar and instrument panel.

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

The dummy’s movement was well controlled. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects.

The Chevrolet Bolt was introduced in the 2017 model year. The car is a plug-in battery-electric vehicle with no gasoline or diesel engine to help power the car. The EPA city and highway values listed below are based on a comparison of the energy content of a kWh of electricity vs. a gallon of gasoline.

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.

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

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.

Headlights Test

The Bolt is available only with poor-rated headlights. They provide fair to good visibility but produce excessive glare for oncoming drivers.

Low beams

On the straightaway, visibility was good on both sides of the road. On curves, visibility was good on both right curves and fair on both left curves. The low beams created excessive glare.

High beams

On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was fair in all 4 tests.
