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 BMW 5 Series Sedan doesn’t offer pretensioners for the rear seat belts.

The XJ offers optional crash mitigation brakes, which use forward mounted sensors to detect an immediately impending crash and automatically apply the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The 5 Series Sedan doesn't offer crash mitigation brakes.

Both the XJ and the 5 Series Sedan have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, plastic fuel tanks, four wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The XJ comes with a full 5 year/50,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The 5 Series Sedan’s 4 year/50,000 mile basic warranty expires 1 year sooner.

Jaguar pays for scheduled maintenance on the XJ for 1 year longer than BMW pays for maintenance for the 5 Series Sedan (5/50,000 vs. 4/50,000).

Tires and Wheels Comparison

For better traction and acceleration, the XJ has larger rear tires than the 5 Series Sedan (275/40R19 vs. 245/45R18).

The XJ’s standard 245/45R19 front and 275/40R19 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the 528i Sedan’s standard 55 series tires. The XJ’s optional 245/40R20 front and 275/35R20 rear tires have a lower 40 series front and 35 series rear profile than the 5 Series Sedan’s optional 45 series tires.

For better ride, handling and brake cooling the XJ has standard 19 inch wheels. Smaller 17 inch wheels are standard on the 528i Sedan. The XJ’s optional 20 inch wheels are larger than the 19 inch wheels optional on the 5 Series Sedan.

The XJ has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the 5 Series Sedan, it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some models of the 5 Series Sedan don’t even offer run-flats.

Suspension and Handling Comparison

The rear suspension of the XJ uses air springs for a smoother, controlled ride than the 5 Series Sedan, 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 5 Series Sedan doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the XJ’s wheelbase is 2.5 inches longer than on the 5 Series Sedan (119.4 inches vs. 116.9 inches). The XJL’s wheelbase is 7.4 inches longer than on the 5 Series Sedan (124.3 inches vs. 116.9 inches).

The XJ Supercharged handles at .87 G’s, while the 535i Sedan pulls only .86 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 550i Sedan (26 seconds @ .71 average G’s vs. 26.1 seconds @ .7 average G’s).

Chassis Comparison

The design of the Jaguar XJ amounts to more than styling. The XJ has an aerodynamic coefficient of drag of .29 Cd. That is lower than the 5 Series Sedan (.29 to .3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the XJ get better fuel mileage.

As tested by Car and Driver, the interior of the XJ Supercharged is quieter than the 535i Sedan:

XJ

5 Series Sedan

Full-Throttle

74 dB

78 dB

70 MPH Cruising

Passenger Space Comparison

The XJL has .1 inches more front legroom and 8 inches more rear legroom than the 5 Series Sedan.

Cargo Capacity Comparison

The XJL has a much larger trunk than the 5 Series Sedan (15.2 vs. 14 cubic feet).

Ergonomics Comparison

Unlike the driver-only memory system in the 5 Series Sedan, 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 air conditioned front seats cool the driver and front passenger and help take the sting out of hot leather in Summer. Air conditioned front seats costs extra on the 5 Series Sedan.

To help keep rear passengers entertained, the XJ offers optional rear seat controls for the radio. The 5 Series Sedan doesn’t offer rear seat audio controls.
