Safety

The XJ offers an optional Surround Camera System to allow the driver to see objects all around the vehicle on a screen. The G80 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Compared to metal, the XJ’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Genesis G80 has a metal gas tank.

Both the XJ and the G80 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.

Warranty

Jaguar pays for scheduled maintenance on the XJ for 2 years and 24,000 miles longer than Genesis pays for maintenance for the G80 (5/60,000 vs. 3/36,000).

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 G80 doesn’t offer an automatic engine start/stop system.

Brakes and Stopping

For better stopping power the XJ’s brake rotors are larger than those on the G80:

Rear Rotors

The XJ’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the G80 3.8 are solid, not vented.

The XJ stops much shorter than the G80:

Tires and Wheels

For better traction, the XJR’s tires are larger than the largest tires available on the G80 (F:265/35R20 & R:295/30R20 vs. F:245/40R19 & R:275/35R19).

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 G80 3.8’s standard 45 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 G80’s optional 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 G80 3.8. The XJ’s optional 20-inch wheels are larger than the 19-inch wheels optional on the G80.

Suspension and Handling

The rear suspension of the XJ uses air springs for a smoother, controlled ride than the G80, 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 G80 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the XJ’s wheelbase is .9 inches longer than on the G80 (119.4 inches vs. 118.5 inches). The XJL’s wheelbase is 5.8 inches longer than on the G80 (124.3 feet vs. 118.5 inches).

The XJ Supercharged handles at .87 G’s, while the G80 AWD pulls only .84 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 G80 5.0 (26 seconds @ .71 average G’s vs. 26.7 seconds @ .7 average G’s).

Chassis

The Jaguar XJ may be more efficient, handle and accelerate better because it weighs about 300 to 550 pounds less than the Genesis G80.

As tested by Car and Driver while cruising at 70 MPH, the interior of the XJL Supercharged is quieter than the G80 5.0 (65 vs. 70 dB).

Passenger Space

For enhanced passenger comfort on long trips the XJ L’s available rear seats recline. The G80’s rear seats don’t recline.

Towing

The XJ has a 4080 lbs. towing capacity. The G80 has no towing capacity.

Ergonomics

Unlike the driver-only memory system in the G80, the XJ offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, seatbelt height and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The XJ’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the G80.

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 G80 can only operate the windows from inside the vehicle, with the ignition on.

Standard air conditioned seats in front and rear seats keep the XJ’s passengers comfortable and take the sting out of hot leather in summer. The G80 only offers an air-conditioned driver’s seat.

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 G80.

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 G80 doesn’t offer an automated parking system.

Recommendations

The XJ was chosen as one of Automobile Magazine’s “All Stars” in 2011. The G80 has never been an “All Star.”
