Tires and Wheels Comparison

For better ride, handling and brake cooling the Accord Coupe Touring has standard 19-inch wheels. The ATS Coupe’s largest wheels are only 18-inches.

The Accord Coupe has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the ATS Coupe, it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling Comparison

The Accord Coupe’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The ATS Coupe doesn’t offer drift compensation steering.

Cargo Capacity Comparison

The Accord Coupe has a much larger trunk than the ATS Coupe (13.7 vs. 10.4 cubic feet).

With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the Accord offers cargo security. The ATS Coupe’s non-lockable folding seat defeats cargo security.

Ergonomics Comparison

If the windows are left down on the Accord Coupe the driver can raise them all using the key in the outside lock cylinder.

The driver of the ATS Coupe can only operate the windows from inside the vehicle, with the ignition on.

The Accord Coupe’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The ATS Coupe’s standard manually variable intermittent wipers have to be constantly adjusted.
