In heavy traffic or at stoplights the XJ’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The G90 doesn’t offer an automatic engine start/stop system.

Brakes and Stopping

For better stopping power the XJ Supercharged/XJR’s front brake rotors are larger than those on the G90:

Tires and Wheels

For better traction, the XJR’s tires are larger than the largest tires available on the G90 (F:265/35R20 & R:295/30R20 vs. F:245/45R19 & R:275/40R19).

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 G90’s 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the XJ offers optional 20-inch wheels. The G90’s largest wheels are only 19-inches.

Suspension and Handling

The rear suspension of the XJ uses air springs for a smoother, controlled ride than the G90, 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 G90 doesn’t offer a load leveling suspension.

The XJ Supercharged handles at .87 G’s, while the G90 5.0 pulls only .83 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 G90 3.3T AWD (26 seconds @ .71 average G’s vs. 26.9 seconds @ .67 average G’s).

Chassis

The Jaguar XJ may be more efficient, handle and accelerate better because it weighs about 750 pounds less than the Genesis G90.

Ergonomics

If the windows are left open on the XJ the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the G90 can only operate the windows from inside the vehicle, with the ignition on.

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 G90 doesn’t offer headlight washers.

The XJ RWD’s optional Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The G90 doesn’t offer an automated parking system.

Recommendations

The XJ was chosen as one of Automobile Magazine’s “All Stars” in 2011. The G90 has never been an “All Star.”
