The AMG GT 4-Door’s 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.

Over 200 people are killed each year when backed over by motor vehicles. The AMG GT 4-Door has a standard Rear Cross Traffic Brake that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Quattroporte doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG GT 4-Door. But it costs extra on the Quattroporte.

The AMG GT 4-Door’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 Quattroporte doesn’t offer a driver alert monitor.

The AMG GT 4-Door has standard Mercedes-Benz Emergency Call, 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 AMG GT 4-Door and the Quattroporte 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, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, available lane departure warning systems and around view monitors.

The Mercedes AMG GT 4-Door weighs 406 to 657 pounds more than the Maserati Quattroporte. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.


The AMG GT 4-Door’s corrosion warranty is 1 year and unlimited miles longer than the Quattroporte’s (5/unlimited vs. 4/50,000).

There are over 3 times as many Mercedes dealers as there are Maserati dealers, which makes it much easier should you ever need service under the AMG GT 4-Door’s warranty.

Fuel Economy and Range

On the EPA test cycle the AMG GT 53 gets better fuel mileage than the Quattroporte S Q4 (19 city/24 hwy vs. 16 city/23 hwy).

An engine control system that can shut down half of the engine’s cylinders helps improve the AMG GT 4-Door 63/63 S’ fuel efficiency. The Quattroporte doesn’t offer a system that can shut down part of the engine.

Regenerative brakes improve the AMG GT 4-Door 53’s fuel efficiency by converting inertia back into energy instead of wasting it. The Quattroporte doesn’t offer a regenerative braking system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG GT 4-Door higher (5 to 6 out of 10) than the Maserati Quattroporte (1). This means the AMG GT 4-Door produces up to 45.9 pounds less smog-producing pollutants than the Quattroporte every 15,000 miles.


A nine-speed automatic is available on the Mercedes AMG GT 4-Door, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Quattroporte.

The AMG GT 4-Door’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Quattroporte doesn’t offer launch control.

Brakes and Stopping

For better stopping power the AMG GT 4-Door’s brake rotors are larger than those on the Quattroporte:

The AMG GT 4-Door offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Quattroporte doesn’t offer ceramic brake rotors.

Tires and Wheels

For better traction, the AMG GT 4-Door has larger standard tires than the Quattroporte (F:255/45R19 & R:285/40R19 vs. F:245/45R19 & R:275/40R19). The AMG GT 63 S’ tires are larger than the largest tires available on the Quattroporte (F:265/40R20 & R:295/35R20 vs. F:245/40R20 & R:285/35R20).

Suspension and Handling

The AMG GT 53 has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The Quattroporte doesn’t offer a load leveling suspension.

For better handling and stability, the average track (width between the wheels) on the AMG GT 4-Door is 1.5 inches wider in the front and .6 inches wider in the rear than the track on the Quattroporte.


The AMG GT 4-Door is 8 inches shorter than the Quattroporte, making the AMG GT 4-Door easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The AMG GT 4-Door’s optional rear seats fold to accommodate long and bulky cargo. The Quattroporte doesn’t offer folding rear seats.


Unlike the driver-only memory system in the Quattroporte, the AMG GT 4-Door has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The AMG GT 4-Door 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 open on the AMG GT 4-Door the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Quattroporte can only operate the windows from inside the vehicle, with the ignition on.

The AMG GT 4-Door’s Active Parking Assist can parallel park by itself, with the driver only controlling speed with the brake pedal. The Quattroporte doesn’t offer an automated parking system.
