Small overlap front: driver-side

Rating applies to 2017-19 models

Tested vehicle: 2017 Chevrolet Bolt EV Premier 4-door hatchback

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.

Restraints and dummy kinematics

Action shot taken during the small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

Restraints and dummy kinematics

Action shot taken during the moderate overlap frontal crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained very well.

Smeared greasepaint indicates where the dummy's head contacted the side curtain airbag during forward movement and rebound.

Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.

Headlights

Ratings are given for 2 different headlight variations available on this vehicle.

Trim level(s)

  • Premier trim equipped with Driver Confidence II package
Low-beam headlight type HID projector
High-beam headlight type HID projector
Curve-adaptive? No
High-beam assist? Yes
Overall rating
Distance at which headlights provide at least 5 lux illumination:

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.

High-beam assist compensates for some limitations of this vehicle's low beams on both left curves.
