2017 Maserati Quattroporte

Safety Comparison

The 7 Series’ pre-crash 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.

The 7 Series has standard Post-Crash Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Quattroporte doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The 7 Series offers an optional backup collision prevention system which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Quattroporte doesn’t offer backup collision prevention brakes.

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 Quattroporte doesn’t offer a night vision system.

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 Quattroporte 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 Quattroporte 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 Quattroporte have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty Comparison

The 7 Series’ corrosion warranty is 8 years and unlimited miles longer than the Quattroporte’s (12/unlimited vs. 4/50,000).

BMW pays for scheduled maintenance on the 7 Series for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Maserati doesn’t pay scheduled maintenance for the Quattroporte.

There are over 3 times as many BMW dealers as there are Maserati dealers, which makes it much easier should you ever need service under the 7 Series’ warranty.

Fuel Economy and Range Comparison

On the EPA test cycle the 740e on a full charge gets better fuel mileage than the Quattroporte S (62 city/68 hwy MPGe vs. 16 city/23 hwy).

On the EPA test cycle the 740e running on gasoline gets better fuel mileage than the Quattroporte S (25 city/29 hwy vs. 16 city/23 hwy).

On the EPA test cycle the 7 Series gets better fuel mileage than the Quattroporte:



7 Series





21 city/29 hwy

16 city/23 hwy




17 city/25 hwy

15 city/22 hwy




20 city/29 hwy

16 city/23 hwy




16 city/25 hwy




Alpina B7/Auto

16 city/25 hwy



The 740e can drive on battery power alone for up to 14 miles. The Quattroporte must run its internal combustion engine to move.

Regenerative brakes improve the 7 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. The Quattroporte doesn’t offer a regenerative braking system.

Brakes and Stopping Comparison

For better stopping power the 750i’s front brake rotors are larger than those on the Quattroporte:



Quattroporte S

Quattroporte GTS

Front Rotors

15.5 inches

14.2 inches

15 inches

Rear Rotors

14.5 inches

13.8 inches

13.8 inches

Tires and Wheels Comparison

For better traction, the Alpina B7’s optional tires are larger than the largest tires available on the Quattroporte (F:255/35R21 & R:295/30R21 vs. F:245/40R20 & R:285/35R20).

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available 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 Quattroporte 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 Quattroporte doesn’t offer an active sway bar system.

The front and rear suspension of the 7 Series uses air springs for a smoother, controlled ride than the Quattroporte, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

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

The 7 Series has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The 7 Series’ height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Quattroporte doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the 7 Series’ wheelbase is 1.6 inches longer than on the Quattroporte (126.4 inches vs. 124.8 inches).

Chassis Comparison

The design of the BMW 7 Series amounts to more than styling. The 7 Series has an aerodynamic coefficient of drag of .27 Cd. That is significantly lower than the Quattroporte (.31) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the 7 Series get better fuel mileage.

Passenger Space Comparison

The 7 Series has 1.3 inches more front headroom, 1.1 inches more rear headroom and 2.4 inches more rear shoulder room than the Quattroporte.

Cargo Capacity Comparison

With its sedan body style and remote trunk release lockout, the 7 Series offers cargo security. The Quattroporte’s non-lockable folding seat and non-lockable remote release defeat cargo security.

A standard locking glovebox keeps your small valuables safer in the 7 Series. The Quattroporte doesn’t offer locking storage for small valuables.

Ergonomics Comparison

Unlike the driver-only memory system in the Quattroporte, the 7 Series offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The 7 Series offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Quattroporte doesn’t offer a heads-up display.

If the windows are left down on the 7 Series the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the Quattroporte can only operate the windows from inside the vehicle, with the ignition on.

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 Quattroporte doesn’t offer an automated parking system.
