The XJ’s standard 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the E-Class Sedan’s standard 45 series tires. The XJR’s 295/30R20 rear tires have a lower 30 series profile than the E-Class Sedan’s optional 35 series tires.
For better ride, handling and brake cooling the XJ has standard 19-inch wheels. Smaller 17-inch wheels are standard on the E-Class Sedan. The XJ’s optional 20-inch wheels are larger than the 19-inch wheels optional on the E-Class Sedan.

The XJ 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 E-Class Sedan doesn’t offer a remote starting system.
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 E-Class Sedan doesn’t offer headlight washers.
