A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The BMW 4 Series Coupe doesn’t offer height adjustable seat belts.

Cadillac’s powertrain warranty covers the ATS Coupe 2 years and 20,000 miles longer than BMW covers the 4 Series Coupe.

There are almost 3 times as many Cadillac dealers as there are BMW dealers, which makes it much easier should you ever need service under the ATS Coupe’s warranty.

For better traction and acceleration, the ATS Coupe has larger rear tires than the 4 Series Coupe (255/35R18 vs. 225/45R18).

The ATS Coupe’s 225/40R18 front and 255/35R18 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the 4 Series Coupe’s standard 45 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the ATS Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. Run-flat tires aren’t available on some tire packages on the 4 Series Coupe.
