For enhanced safety, the front and rear seat shoulder belts of the Ford F-150 Lightning have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The GMC Sierra EV doesn’t offer pretensioners for its rear seat belts.
The F-150 Lightning has standard Post-Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Sierra EV doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
When descending a steep, off-road slope, the F-150 Lightning’s optional Hill Descent Control allows you to creep down safely. The Sierra EV doesn’t offer Hill Descent Control.
Both the F-150 Lightning and the Sierra EV have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
