For enhanced safety, the front and rear seat shoulder belts of the Audi TT have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Ford Mustang doesn’t offer pretensioners for its rear seat belts.
The TT has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Mustang 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 TT has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Mustang doesn’t offer all-wheel drive.
The TT has standard Parking System Plus to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The Mustang doesn’t offer a front parking aid.
Both the TT and the Mustang have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems and rearview cameras.
