Both the XJ and the CLS have standard driver and passenger frontal airbags, front side-impact 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 and available around view monitors.


The XJ comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The CLS’ 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

The XJ’s corrosion warranty is 1 year longer than the CLS’ (6 vs. 5 years).

Tires and Wheels

For better traction, the XJR’s tires are larger than the largest tires available on the CLS (F:265/35R20 & R:295/30R20 vs. F:245/40R19 & R:275/35R19).

The XJR’s 265/35R20 front and 295/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the CLS’ 40 series front and 35 series rear tires.

Suspension and Handling

The rear suspension of the XJ uses air springs for a smoother, controlled ride than the CLS, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The XJ has a standard automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The CLS doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the XJ’s wheelbase is 3.7 inches longer than on the CLS (119.4 inches vs. 115.7 inches). The XJL’s wheelbase is 8.6 inches longer than on the CLS (124.3 inches vs. 115.7 inches).

The XJ’s front to rear weight distribution is more even (51.1% to 48.9%) than the CLS’ (53.9% to 46.1%). This gives the XJ more stable handling and braking.


The Jaguar XJ may be more efficient, handle and accelerate better because it weighs about 100 to 250 pounds less than the Mercedes CLS.

As tested by Car and Driver while under full throttle, the interior of the XJL Supercharged is quieter than the CLS 450 4MATIC (71 vs. 74 dB).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the XJ a Large car, while the CLS is rated a Compact.

The XJ has 9 cubic feet more passenger volume than the CLS (102 vs. 93).

The XJ has 2.6 inches more front headroom, 1.3 inches more rear headroom, 3.9 inches more rear legroom and .1 inches more rear shoulder room than the CLS.

Cargo Capacity

The XJ has a much larger trunk than the CLS (15.2 vs. 11.9 cubic feet).


In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The XJ offers available headlight washers to keep headlight output high. The CLS doesn’t offer headlight washers.

The XJ has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the CLS.


The XJ was chosen as one of Automobile Magazine’s “All Stars” in 2011. The CLS has never been an “All Star.”

The Jaguar XJ outsold the Mercedes CLS by 67% during 2018.
