The XF’s optional front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Quattroporte doesn’t offer pre-crash pretensioners.
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 Maserati Quattroporte has only front height-adjustable seat belts.
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 Quattroporte 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 Quattroporte 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 Quattroporte 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 Quattroporte doesn’t offer a system to reveal objects in the driver’s blind spots.
Both the XF and the Quattroporte 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.
The XF comes with a full 5 year/50,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The Quattroporte’s 4 year/50,000 mile basic warranty expires 1 year sooner.
The XF’s corrosion warranty is 2 years and unlimited miles longer than the Quattroporte’s (6/unlimited vs. 4/50,000).
Jaguar pays for scheduled maintenance on the XF for 5 years and 50,000 miles. Jaguar will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. Maserati doesn’t pay scheduled maintenance for the Quattroporte.
There are almost 3 times as many Jaguar dealers as there are Maserati dealers, which makes it much easier should you ever need service under the XF’s warranty.
The XF has more powerful engines than the Quattroporte:

On the EPA test cycle the XF 3.0 Supercharged RWD V6 gets better fuel mileage than the Quattroporte S (18 city/28 hwy vs. 12 city/18 hwy). The XFR/XF Supercharged gets better fuel mileage than the Quattroporte S (15 city/23 hwy vs. 12 city/18 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 Quattroporte doesn’t offer an automatic engine start/stop system.
For better stopping power the XFR/Supercharged’s front brake rotors are larger than those on the Quattroporte:
XFR/Supercharged |
Quattroporte |
|
Front Rotors |
15 inches |
14.2 inches |
Rear Rotors |
14.8 inches |
13 inches |
In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The XF has a standard Emergency Brake Assist to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Quattroporte doesn’t offer a brake assist feature.
The XF stops shorter than the Quattroporte:

For better traction, the XFR/Supercharged’s front tires are larger than the largest tires available on the Quattroporte (F:255/35R20 & R:285/30R20 vs. F:245/45R18 & R:285/40R18).
The XFR handles at .89 G’s, while the Quattroporte pulls only .83 G’s of cornering force in a Car and Driver skidpad test.
The XFR goes through Road & Track’s slalom 1.4 MPH faster than the Quattroporte (67.2 vs. 65.8 MPH).
The XFR executes Motor Trend’s “Figure Eight” maneuver quicker than the Quattroporte S (25.9 seconds @ .74 average G’s vs. 26.3 seconds @ .67 average G’s).
For better maneuverability, the XF’s turning circle is 2.8 feet tighter than the Quattroporte’s (37.7 feet vs. 40.5 feet).
The Jaguar XF may be more efficient, handle and accelerate better because it weighs about 250 to 700 pounds less than the Maserati Quattroporte.
The XF is 5.4 inches shorter than the Quattroporte, making the XF easier to handle, maneuver and park in tight spaces.
The design of the Jaguar XF amounts to more than styling. The XF has an aerodynamic coefficient of drag of .29 Cd. That is significantly lower than the Quattroporte (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the XF get better fuel mileage.
As tested by Car and Driver, the interior of the XFR is quieter than the Quattroporte Sport GT S:
XF |
Quattroporte |
|
At idle |
44 dB |

Full-Throttle |

The XF has .6 inches more front headroom and 2.6 inches more rear headroom than the Quattroporte.
The XF has a much larger trunk than the Quattroporte (17.7 vs. 15.9 cubic feet).
The XF’s optional rear seats fold to accommodate long and bulky cargo. The Quattroporte doesn’t offer folding rear seats.
The XF’s standard power windows have a locking feature to keep children in the rear seat from operating them. Maserati does not offer a locking feature on the Quattroporte’s standard power windows.
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 Quattroporte doesn’t offer automatic dimming high beams.
To keep a safe, consistent following distance, the XF offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Quattroporte doesn’t offer an adaptive cruise control.
The XF’s standard steering wheel mounted cruise control is close at hand. The Quattroporte’s standard cruise control is on an over-crowded turn signal stalk.
The XF’s available GPS navigation system has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service available in a limited number of metro areas.) The Quattroporte’s navigation system doesn’t offer real-time traffic updates.
