Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Jaguar XJ have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Audi A8 doesn’t offer pretensioners for the rear seat belts.

To help make backing safer, the XJ’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The A8 doesn’t offer a cross-path warning system.

The XJ has standard InControl, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The A8 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the XJ and the A8 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes and around view monitors.

Warranty Comparison

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 A8’s 4 year/50,000 mile basic warranty expires 1 year and 10,000 miles sooner.

Jaguar pays for scheduled maintenance on the XJ for 5 years and 60,000 miles. Jaguar will pay for oil changes, lubrication and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the A8.

Car and Driver

Tires and Wheels Comparison

For better traction and acceleration, the XJ has larger standard rear tires than the A8 (275/40R19 vs. 255/45R19). The XJR’s rear tires are larger than the largest rear tires available on the A8 (295/30R20 vs. 275/35R21).

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 A8’s standard 45 series tires. The XJR’s 295/30R20 rear tires have a lower 30 series profile than the A8 4.0T’s optional 35 series tires.

Suspension and Handling Comparison

For a smoother ride and more stable handling, the XJL’s wheelbase is 1.4 inches longer than on the A8 (124.3 inches vs. 122.9 inches).

The XJ’s front to rear weight distribution is more even (51.1% to 48.9%) than the A8’s (55.9% to 44.1%). This gives the XJ more stable handling and braking.

The XJ Supercharged handles at .87 G’s, while the A8 L 4.0T pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the XJ’s turning circle is 2.7 feet tighter than the A8 L’s (39 feet vs. 41.7 feet).

Chassis Comparison

The Jaguar XJ may be more efficient, handle and accelerate better because it weighs about 500 to 550 pounds less than the Audi A8.

The XJ is 5.4 inches shorter than the A8, making the XJ easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver while cruising at 70 MPH, the interior of the XJL Supercharged is quieter than the A8 L 4.0T (65 vs. 67 dB).

Passenger Space Comparison

The XJ has 2.3 inches more front headroom and .1 inches more front legroom than the A8 L.

Cargo Capacity Comparison

The XJ has a larger trunk than the A8 L (15.2 vs. 14.2 cubic feet).

Ergonomics Comparison

If the windows are left down on the XJ the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the A8 can’t use the remote to operate the windows.

When the XJ is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The A8’s mirrors don’t automatically adjust for backing.

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 A8.

Standard InControl Apps for the XJ allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations and other connected activities without taking their eyes off the road or their hands from the wheel. The A8 doesn’t offer factory integrated smartphone program access.

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 A8 doesn’t offer an automated parking system.

Economic Advantages Comparison

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Jaguar XJ will be $143 to $5240 less than for the Audi A8.

Recommendations Comparison

The XJ was chosen as one of Automobile Magazine’s “All Stars” in 2011. The A8 hasn’t been picked since 2005.
