For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG GLA 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 Jeep Grand Cherokee SRT doesn’t offer pretensioners for the rear seat belts.
The AMG GLA’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Grand Cherokee SRT doesn’t offer pre-crash pretensioners.
The AMG GLA offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Grand Cherokee SRT 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.
The AMG GLA offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Grand Cherokee SRT only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The AMG GLA’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Grand Cherokee SRT doesn’t offer a driver alert monitor.
Both the AMG GLA and the Grand Cherokee SRT have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.
