The AMG CLA’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GTI doesn’t offer pre-crash pretensioners.
The Mercedes AMG CLA has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GTI doesn’t offer knee airbags.
The AMG CLA has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The GTI doesn’t offer all-wheel drive.
The AMG CLA offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The GTI 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.
Both the AMG CLA and the GTI have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available lane departure warning systems.
The Mercedes AMG CLA weighs 414 to 608 pounds more than the Volkswagen GTI. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
