Car and Driver

Tires and Wheels

For better traction and acceleration, the CLS has larger rear tires than the 5 Series Sedan (275/35R19 vs. 245/45R18).

The CLS’ 245/40R19 front and 275/35R19 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 5 Series Sedan’s standard 45 series tires.

For better ride, handling and brake cooling the CLS 450 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 5 Series Sedan.

Suspension and Handling

The CLS’ 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 5 Series Sedan doesn’t offer drift compensation steering.

The CLS 450 4MATIC handles at .93 G’s, while the 540i pulls only .87 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the CLS’ turning circle is .4 feet tighter than the 5 Series Sedan’s (39.1 feet vs. 39.5 feet). The CLS’ turning circle is 1 foot tighter than the 5 Series Sedan xDrive’s (39.1 feet vs. 40.1 feet).

Passenger Space

The CLS has .5 inches more front legroom and .6 inches more rear shoulder room than the 5 Series Sedan.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than BMW. J.D. Power ranks Mercedes 6th in service department satisfaction (above the industry average). With a 11% lower rating, BMW is ranked 8th.

Ergonomics

The CLS 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 5 Series Sedan doesn’t offer a remote starting system.

The CLS offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The 5 Series Sedan doesn’t offer a house-current electrical outlet.
