The XJ has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The A6 doesn’t offer a whiplash protection system.

The XJ’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The A6 doesn’t offer a driver alert monitor.

Both the XJ and the A6 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, rearview cameras and available around view monitors.


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 A6’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 A6.


The XJ’s standard 3.0 supercharged V6 produces 5 more horsepower (340 vs. 335) than the A6’s 3.0 turbo V6 hybrid. The XJ Supercharged’s standard 5.0 supercharged V8 produces 135 more horsepower (470 vs. 335) and 55 lbs.-ft. more torque (424 vs. 369) than the A6’s 3.0 turbo V6 hybrid. The XJR575’s standard 5.0 supercharged V8 produces 240 more horsepower (575 vs. 335) and 148 lbs.-ft. more torque (517 vs. 369) than the A6’s 3.0 turbo V6 hybrid.

Tires and Wheels

For better traction, the XJR’s tires are larger than the largest tires available on the A6 (F:265/35R20 & R:295/30R20 vs. 255/40R20).

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 A6’s standard 45 series tires. The XJR’s 295/30R20 rear tires have a lower 30 series profile than the A6 Prestige’s optional 35 series tires.

Suspension and Handling

The rear suspension of the XJ uses air springs for a smoother, controlled ride than the A6, 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 A6 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the XJ’s wheelbase is 4.3 inches longer than on the A6 (119.4 inches vs. 115.1 inches). The XJL’s wheelbase is 9.2 inches longer than on the A6 (124.3 inches vs. 115.1 inches).

The XJ’s front to rear weight distribution is more even (51.1% to 48.9%) than the A6’s (55% to 45%). This gives the XJ more stable handling and braking.


The Jaguar XJ may be more efficient, handle and accelerate better because it weighs about 100 to 400 pounds less than the Audi A6.

Passenger Space

The XJ has 1.5 inches more front headroom, .2 inches more front legroom, 1.5 inches more rear legroom and .1 inches more rear shoulder room than the A6.

For enhanced passenger comfort on long trips the XJ L’s available rear seats recline. The A6’s rear seats don’t recline.

Cargo Capacity

The XJ has a much larger trunk than the A6 (15.2 vs. 13.7 cubic feet).


The XJ’s standard towing capacity is much higher than the A6’s (4080 vs. 3500 pounds).


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 A6 doesn’t offer a remote starting system.

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 A6 doesn’t offer air-conditioned seats in the rear.

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 A6.

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 A6 doesn’t offer an automated parking system.

Model Availability

The XJ is available in both rear-wheel drive and all-wheel drive configurations. The A6 doesn’t offer a two-wheel drive configuration.


The XJ was chosen as one of Automobile Magazine’s “All Stars” in 2011. The A6 has never been an “All Star.”
