Both the CLS and the LS Series have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems, around view monitors and rear cross-path warning.


There are over 59 percent more Mercedes dealers than there are Lexus dealers, which makes it much easier should you ever need service under the CLS’ warranty.

Car and Driver

Tires and Wheels

For better traction and acceleration, the CLS has larger rear tires than the LS Series (275/35R19 vs. 245/50R19).

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 LS Series’ standard 50 series tires. The CLS’ tires are lower profile than the LS Series F Sport’s 45 series front and 40 series rear tires.

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 LS Series doesn’t offer drift compensation steering.

The CLS 450 4MATIC handles at .93 G’s, while the LS 500 pulls only .88 G’s of cornering force in a Car and Driver skidpad test.


The Mercedes CLS may be more efficient, handle and accelerate better because it weighs about 550 to 850 pounds less than the Lexus LS Series.

The CLS is 9.4 inches shorter than the LS Series, making the CLS easier to handle, maneuver and park in tight spaces.

The design of the Mercedes CLS amounts to more than styling. The CLS has an aerodynamic coefficient of drag of .27 Cd. That is lower than the LS Series (.27 to .3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the CLS get better fuel mileage.

Passenger Space

The CLS has .9 inches more front legroom and .1 inches more rear shoulder room than the LS Series.

Cargo Capacity

The CLS’ standard rear seats fold to accommodate long and bulky cargo. The LS Series doesn’t offer folding rear seats.


The CLS’ optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The LS Series doesn’t offer an automated parking system.
