Tires and Wheels

For better traction, the XJR’s tires are larger than the largest tires available on the S-Class (F:265/35R20 & R:295/30R20 vs. F:255/40R20 & R:285/35R20).

The XJ’s standard 245/45R19 front and 275/40R19 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the S-Class’ standard 50 series tires. The XJR’s 265/35R20 front and 295/30R20 rear tires have a lower 35 series front and 30 series rear profile than the S 63’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the XJ has standard 19-inch wheels. Smaller 18-inch wheels are standard on the S-Class.

The XJ has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the S-Class; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some models of the S-Class don’t even offer run-flats.

Suspension and Handling

The XJ Supercharged handles at .87 G’s, while the S-Class pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

The XJL Supercharged executes Motor Trend’s “Figure Eight” maneuver quicker than the S 560 (26 seconds @ .71 average G’s vs. 26.5 seconds @ .7 average G’s).

Chassis

The Jaguar XJ may be more efficient, handle and accelerate better because it weighs about 650 to 850 pounds less than the Mercedes S-Class.

The XJ is shorter than the S-Class, making the XJ easier to handle, maneuver and park in tight spaces:

Passenger Space

The XJ has .1 inches more front legroom and 4.8 inches more rear legroom than the S-Class.

Towing

The XJ has a 4080 lbs. towing capacity. The S-Class has no towing capacity.

Ergonomics

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 S-Class 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 S-Class.

Recommendations

The XJ was chosen as one of Automobile Magazine’s “All Stars” in 2011. The S-Class hasn’t been picked since 2008.
