Safety Comparison

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

The XF offers an optional Intelligent Emergency Brake, which uses 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 IS F doesn't offer crash mitigation brakes.

The XF 3.0 offers all wheel drive to maximize traction under poor conditions, especially in ice and snow. The IS F doesn’t offer all wheel drive.

The XF’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The IS F doesn’t offer a system to reveal objects in the driver’s blind spots.

Both the XF and the IS F 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.

Engine Comparison

The XF Supercharged’s standard 5.0 supercharged V8 produces 54 more horsepower (470 vs. 416) and 53 lbs.-ft. more torque (424 vs. 371) than the IS F’s 5.0 DOHC V8. The XFR’s standard 5.0 supercharged V8 produces 94 more horsepower (510 vs. 416) and 90 lbs.-ft. more torque (461 vs. 371) than the IS F’s 5.0 DOHC V8.

Fuel Economy and Range Comparison

On the EPA test cycle the XF 3.0 Supercharged RWD gets better fuel mileage than the IS F (18 city/28 hwy vs. 16 city/23 hwy).

In heavy traffic or at stoplights the XF V6/V8’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The IS F doesn’t offer an automatic engine start/stop system.

The XF has 1.5 gallons more fuel capacity than the IS F (18.4 vs. 16.9 gallons), for longer range between fill-ups.

Brakes and Stopping Comparison

For better stopping power the XFR/Supercharged’s front brake rotors are larger than those on the IS F:



Front Rotors

15 inches

14.2 inches

Rear Rotors

14.8 inches

13.6 inches

The XF’s brakes have 28% more swept area (the area covered by the brake pads) than the IS F (774 vs. 606 square inches), so the XF has more braking power available.

The XF stops much shorter than the IS F:

Tires and Wheels Comparison

For better traction, the XF has larger standard tires than the IS F (235/35R20 vs. 225/40R19). The XFR/Supercharged’s tires are larger than the largest tires available on the IS F (F:255/35R20 & R:285/30R20 vs. F:225/40R19 & R:255/35R19).

The XFR/Supercharged’s 255/35R20 front and 285/30R20 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 IS F’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the XF offers optional 20-inch wheels. The IS F’s largest wheels are only 19-inches.

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 IS F 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 IS F’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the XF’s wheelbase is 7 inches longer than on the IS F (114.5 inches vs. 107.5 inches).

For better handling and stability, the average track (width between the wheels) on the XF is 2.9 inches wider in the rear than the track on the IS F.

Chassis Comparison

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



At idle

Passenger Space Comparison

Because it has more passenger and cargo room, the XF is rated a Mid-size car by the EPA, while the IS F is rated a Subcompact.

The XF has standard seating for 5 passengers; the IS F can only carry 4.

The XF has 12.3 cubic feet more passenger volume than the IS F (98 vs. 85.7).

The XF has 2.5 inches more front shoulder room, .9 inches more rear headroom, 6 inches more rear legroom and 3.7 inches more rear shoulder room than the IS F.

Cargo Capacity Comparison

The XF has a much larger trunk than the IS F (17.7 vs. 13.3 cubic feet).

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

Ergonomics Comparison

The power windows standard on both the XF and the IS F 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 IS F prevents the driver from operating the other windows just as it does the other passengers.

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 IS F doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the XF offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The IS F doesn’t offer cornering lights.

The XF’s optional air conditioned front seats cool the driver and front passenger and help take the sting out of hot leather in Summer. The IS F doesn’t offer air conditioned front seats.

Economic Advantages Comparison

Insurance will cost less for the XF owner. The Complete Car Cost Guide estimates that insurance for the XF will cost $4545 less than the IS F over a five-year period.

Intellichoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Jaguar XF will be $7908 less than for the Lexus IS F.
