The CLA’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the A4’s standard 50 series tires.

For better ride, handling and brake cooling the CLA has standard 18-inch wheels. Smaller 17-inch wheels are standard on the A4.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the CLA can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The A4 doesn’t offer run-flat tires.

The CLA’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 A4 doesn’t offer drift compensation steering.

For better handling and stability, the track (width between the wheels) on the CLA is 1.6 inches wider in the front and 1.9 inches wider in the rear than on the A4.

For better maneuverability, the CLA’s turning circle is 2 feet tighter than the A4’s (36.1 feet vs. 38.1 feet).

The CLA has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The A4 doesn’t offer a remote starting system.

Unlike the driver-only memory seat and mirrors optional at extra cost in the A4, the CLA has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The A4’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The CLA’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes CLA offers an optional wireless phone charging system (Qi) in the center console. The A4 doesn’t offer wireless personal charging.

The CLA’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The A4 doesn’t offer an automated parking system.
