Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Jaguar XF are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Infiniti M Series has only front height-adjustable seat belts.

Both the XF and the M Series have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Tires and Wheels Comparison

For better traction, the XFR/Supercharged’s tires are larger than the largest tires available on the M Series (F:255/35R20 & R:285/30R20 vs. 245/40R20).

The XF’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the M Series’ standard 50 series tires. The XFR/Supercharged’s 255/35R20 front and 285/30R20 rear tires have a lower 35 series front and 30 series rear profile than the M Series’ optional 40 series tires.

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

Suspension and Handling Comparison

The XF offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The M Series’ suspension doesn’t offer adjustable shock absorbers.

The XFR handles at .89 G’s, while the M37 pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

The XFR goes through Road & Track’s slalom faster than the M56 (67.2 vs. 66.7 MPH).

The XFR executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the M Hybrid (25.9 seconds @ .74 average G’s vs. 26.9 seconds @ .68 average G’s).

Chassis Comparison

The Jaguar XF may be more efficient, handle and accelerate better because it weighs about 100 to 200 pounds less than the Infiniti M Series.

As tested by Road & Track, the interior of the XFR is quieter than the M56:

Cargo Capacity Comparison

The XF has a much larger trunk than the M Series (17.7 vs. 14.9 cubic feet).

The XF’s optional rear seats fold to accommodate long and bulky cargo. The M Series doesn’t offer folding rear seats, only a ski pass-through.

Ergonomics Comparison

The power windows standard on both the XF and the M Series have locks to prevent small children from operating them. When the lock on the XF is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The M Series prevents the driver from operating the other windows just as it does the other passengers.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The XF has standard headlight washers to keep headlight output high. The M Series doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the XF detect other vehicles which could be blinded and automatically switch to low beams. The M Series doesn’t offer automatic dimming high beams.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the XF is less expensive to operate than the M Series because it costs $315 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost less on the XF than the M Series, including $44 less for a water pump, $156 less for an alternator and $141 less for front struts.
