Small overlap front: driver-side
Tested vehicle: 2014 Chevrolet Volt 4-door
Rating applies to 2014-15 models
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 38 miles for 2014 models according to the EPA. After the electric-only mode ends, the gas engine kicks in to power the vehicle.
Beginning with 2014 models, the front structure was modified to improve occupant protection in small overlap frontal crashes.

| Driver restraints and dummy kinematics The dummy’s head barely contacted the frontal airbag before sliding off the left side, leaving the head vulnerable to contact with forward structure. The side curtain airbag deployed and had sufficient forward coverage to protect the head from contact with side structure and outside objects. |
