2014 Jaguar XJ

Safety Comparison

The 7 Series offers optional City Collision Mitigation, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The XJ offers an available collision warning system without the automated brake feature which would prevent or reduce the collision if the driver fails to react.

An active infrared night vision system optional on the 7 Series helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then projects the image on the windshield, near the driver’s line of sight. The XJ doesn’t offer a night vision system.

The 7 Series’ optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The XJ doesn’t offer a lane departure warning system.

The 7 Series offers an optional Side and Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The XJ 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.

The 7 Series’ 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 XJ doesn’t offer a driver alert monitor.

The 7 Series has standard BMW Assist, 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 XJ 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 7 Series and the XJ have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The 7 Series’ corrosion warranty is 6 years longer than the XJ’s (12 vs. 6 years).

BMW pays for scheduled maintenance on the 7 Series for 4 years and 50,000 miles. BMW will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. Jaguar only pays for the first scheduled maintenance visit on the XJ.

There are over 2 times as many BMW dealers as there are Jaguar dealers, which makes it much easier should you ever need service under the 7 Series’ warranty.

Reliability Comparison

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without their vehicle while it’s being repaired. Consumer Reports predicts that the 7 Series’ reliability will be 45% better than the XJ.

J.D. Power and Associates’ 2013 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Jaguar vehicles. J.D. Power ranks BMW 16th in reliability. With 31 more problems per 100 vehicles, Jaguar is ranked 27th.

Tires and Wheels Comparison

The Alpina B7’s 245/35R21 front and 285/30R21 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 XJ’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the Alpina B7 has standard 21-inch wheels. The XJ’s largest wheels are only 20-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 7 Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The XJ doesn’t offer run-flat tires.

Suspension and Handling Comparison

The 7 Series offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The XJ doesn’t offer an active sway bar system.

The 7 Series SWB offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Jaguar doesn’t offer an active suspension on the XJ.

For a smoother ride and more stable handling, the 7 Series’ wheelbase is longer than on the XJ:

7 Series


SWB Sedan

120.9 inches

119.4 inches

LWB Sedan

126.4 inches

124.3 inches

For better handling and stability, the track (width between the wheels) on the 7 Series is 1.9 inches wider in the rear than on the XJ.

The Alpina B7 LWB xDrive handles at .93 G’s, while the XJL Supercharged pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

The 750Li goes through Road & Track’s slalom 3.9 MPH faster than the XJL Supercharged (68.7 vs. 64.8 MPH).

The 750Li performs Car and Driver’s emergency lane change maneuver 10.1 MPH faster than the XJL Supercharged (68.3 vs. 58.2 MPH).

The 740i executes Motor Trend’s “Figure Eight” maneuver quicker than the XJL Portfolio (25.8 seconds @ .73 average G’s vs. 26.4 seconds @ .66 average G’s).

For better maneuverability, the 7 Series’ turning circle is tighter than the XJ’s:

7 Series

40.4 feet

LWB Sedan

41.7 feet

41.7 feet


40 feet

40.4 feet

Passenger Space Comparison

The 7 Series SWB has 7 cubic feet more passenger volume than the XJ (106 vs. 99).

The 7 Series SWB has 1.1 inches more front headroom, 3.8 inches more front shoulder room, 1.3 inches more rear headroom and 2.3 inches more rear shoulder room than the XJ.

Cargo Capacity Comparison

A low lift-over trunk design makes loading and unloading the 7 Series easier. The 7 Series’ trunk lift-over height is 27.1 inches, while the XJ’s liftover is 28.5 inches.

To make loading groceries and cargo easier when your hands are full, the 7 Series’ trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The XJ doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Ergonomics Comparison

The 7 Series offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The XJ doesn’t offer a heads-up display.

Heated windshield washer nozzles are standard on the 7 Series to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The XJ doesn’t offer heated windshield washer nozzles.

Standard BMW Apps for the 7 Series allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, tagging songs to buy them later, following twitter accounts and other connected activities without taking their eyes off the road or their hands from the wheel. The XJ doesn’t offer factory integrated smartphone program access.

The 7 Series’ optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The XJ doesn’t offer an automated parking system.

Recommendations Comparison

The BMW 7 Series won the Check it Out award in Kiplinger’s 2013 car issue. The Jaguar XJ didn't win any award.

Strategic Vision rates overall owner satisfaction with vehicle quality. The BMW 7 Series is ranked above average in the Luxury Car category. The Jaguar XJ is ranked below average.

The BMW 7 Series outsold the Jaguar XJ by over two to one during the 2013 model year.
