For enhanced safety, the front and rear seat shoulder belts of the Jaguar XF 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 Infiniti Q50 doesn’t offer pretensioners for its rear seat belts.

Both the XF and Q50 have child safety locks to prevent children from opening the rear doors. The XF has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Q50’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The XF’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 Q50 doesn’t offer a driver alert monitor.

Both the XF and the Q50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The XF comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Q50’s 4-year/60,000-mile basic warranty expires 1 year sooner.

Jaguar pays for scheduled maintenance on the XF for 2 years and 24,000 miles longer than Infiniti pays for maintenance for the Q50 (5/60,000 vs. 3/36,000).

Fuel Economy and Range

On the EPA test cycle the XF gets better mileage than the Q50:

			MPG
XF
	RWD	2.0 turbo 4-cyl.	25 city/33 hwy
	AWD	2.0 turbo 4-cyl.	22 city/30 hwy
Q50
	RWD	3.0 turbo V6	20 city/29 hwy
		Red Sport 400 3.0 turbo V6	20 city/26 hwy
	AWD	3.0 turbo V6	19 city/27 hwy
		Red Sport 400 3.0 turbo V6	19 city/26 hwy

Regenerative brakes improve the XF’s fuel efficiency by converting inertia back into energy instead of wasting it. The Q50 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the XF’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. The Q50 doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Jaguar XF higher (7 out of 10) than the Infiniti Q50 (3). This means the XF produces up to 24.5 pounds less smog-producing pollutants than the Q50 every 15,000 miles.

Transmission

An eight-speed automatic is standard on the Jaguar XF, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Q50.

Brakes and Stopping

For better stopping power the XF’s brake rotors are larger than those on the Q50:

	XF	Q50
Front Rotors	14 inches	12.6 inches
Rear Rotors	12.8 inches	12.1 inches

Tires and Wheels

For better traction, the XF has larger standard tires than the Q50 (245/45R18 vs. 225/50R18). The XF’s optional tires are larger than the largest tires available on the Q50 (255/35R20 vs. 245/40R19).

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 Q50 Luxe’s standard 50 series tires. The XF’s optional tires have a lower 35 series profile than the Q50 Red Sport 400’s 40 series front tires.

For better ride, handling and brake cooling the XF offers optional 20-inch wheels. The Q50’s largest wheels are only 19-inches.

The XF 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 Q50; 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.

Suspension and Handling

For a smoother ride and more stable handling, the XF’s wheelbase is 4.3 inches longer than on the Q50 (116.5 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the XF is 2.6 inches wider in the front and 1.7 inches wider in the rear than the average track on the Q50.

Passenger Space

The XF has .2 inches more front shoulder room, 1.4 inches more rear headroom, 2.6 inches more rear legroom and .3 inches more rear shoulder room than the Q50.

Cargo Capacity

To make loading and unloading groceries and cargo easier when your hands are full, the XF’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The Q50 doesn’t offer a power or hands-free opening trunk.

Towing

Standard Trailer Stability Assist on the XF uses the Dynamic Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Q50 doesn’t offer electronic trailer sway control.

Servicing Ease

The XF has a maintenance free battery for long life without checking the battery’s water level. The Q50 doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

Ergonomics

Unlike the driver-only memory system in the Q50, the XF SE/R-Dynamic has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster) and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The XF SE/R-Dynamic offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Q50 doesn’t offer a heads-up display.

The XF’s power parking brake sets with one touch and releases with one touch or automatically. The Q50’s parking brake has to be released manually.

The power windows standard on both the XF and the Q50 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 Q50 prevents the driver from operating the other windows just as it does the other passengers.

Heated windshield washer nozzles are optional on the XF to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Q50 doesn’t offer heated windshield washer nozzles.

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 SE/R-Dynamic offers available headlight washers to keep headlight output high. The Q50 doesn’t offer headlight washers.

A power rear sunshade is optional in the XF SE/R-Dynamic to help block heat and glare for the rear passengers. The Q50 doesn’t offer a rear sunshade.

Both the XF and the Q50 have standard heated front seats. The XF SE/R-Dynamic also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Q50.

Optional air-conditioned seats in the XF SE/R-Dynamic keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q50 doesn’t offer air-conditioned seats.

The XF R-Dynamic offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Q50.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Jaguar XF has a standard wireless phone charging system (Qi) in the center console. The Q50 doesn’t offer wireless personal charging.

The XF 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 Q50 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the XF owner. The Complete Car Cost Guide estimates that insurance for the XF will cost $1170 to $9165 less than the Q50 over a five-year period.
