Warranty

There are over 2 times as many Mercedes dealers as there are Jaguar dealers, which makes it much easier should you ever need service under the CLS’ warranty.

Regenerative brakes improve the CLS’ fuel efficiency by converting inertia back into energy instead of wasting it. The XJ doesn’t offer a regenerative braking system.

Transmission

A nine-speed automatic is available on the Mercedes CLS, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the XJ.

Brakes and Stopping

For better stopping power the CLS’ standard brake rotors are larger than those on the XJ:

Tires and Wheels

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 XJ’s standard 45 series front and 40 series rear tires.

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

The CLS 450 4MATIC handles at .93 G’s, while the XJL Supercharged pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The CLS is 5.3 inches shorter than the XJ, 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 XJ (.29) 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 .4 inches more front legroom and .2 inches more front shoulder room than the XJ.

Cargo Capacity

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

To make loading groceries and cargo easier when your hands are full, the CLS’ trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The XJ doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Jaguar. J.D. Power ranks Mercedes 6th in service department satisfaction (above the industry average). With a 27% lower rating, Jaguar is ranked 15th.

Ergonomics

The CLS offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The XJ doesn’t offer a heads-up display.

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 XJ doesn’t offer a house-current electrical outlet.
