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 GS F 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 GS F doesn’t offer backup collision prevention brakes.

The AMG GT 4-Door has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The GS F doesn’t offer all-wheel drive.

The AMG GT 4-Door offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The GS F only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

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 GS F doesn’t offer a driver alert monitor.

Both the AMG GT 4-Door and the GS F have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.

The Mercedes AMG GT 4-Door weighs 605 to 724 pounds more than the Lexus GS F. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.


There are over 59 percent more Mercedes dealers than there are Lexus dealers, which makes it much easier should you ever need service under the AMG GT 4-Door’s warranty.


The AMG GT 63’s standard 4.0 turbo V8 produces 110 more horsepower (577 vs. 467) and 201 lbs.-ft. more torque (590 vs. 389) than the GS F’s 5.0 DOHC V8. The AMG GT 63 S’ standard 4.0 turbo V8 produces 163 more horsepower (630 vs. 467) and 275 lbs.-ft. more torque (664 vs. 389) than the GS F’s 5.0 DOHC V8.

Fuel Economy and Range

On the EPA test cycle the AMG GT 53 gets better fuel mileage than the GS F (19 city/24 hwy vs. 16 city/24 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 GS F 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 GS F doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the AMG GT 4-Door’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 GS F doesn’t offer an automatic engine start/stop system.


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 GS F.

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 GS F doesn’t offer launch control.

Brakes and Stopping

For better stopping power the AMG GT 63 4-Door’s brake rotors are larger than those on the GS F:

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 GS F doesn’t offer ceramic brake rotors.

Tires and Wheels

For better traction, the AMG GT 63 S’ tires are larger than the largest tires available on the GS F (F:265/40R20 & R:295/35R20 vs. F:255/35R19 & R:275/35R19).

For better ride, handling and brake cooling the AMG GT 4-Door offers optional 21-inch wheels. The GS F’s largest wheels are only 19-inches.

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 GS F doesn’t offer a load leveling suspension.

The AMG GT 4-Door’s drift compensation steering can automatically compensate for road conditions that would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The GS F doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the AMG GT 4-Door’s wheelbase is 4 inches longer than on the GS F (116.2 inches vs. 112.2 inches).

For better handling and stability, the average track (width between the wheels) on the AMG GT 4-Door is 4.6 inches wider in the front and 4 inches wider in the rear than the track on the GS F.

Passenger Space

The AMG GT 4-Door has 5.2 cubic feet more passenger volume than the GS F (96 vs. 90.8).

Cargo Capacity

The AMG GT 4-Door’s optional rear seats fold to accommodate long and bulky cargo. The GS F doesn’t offer folding rear seats, only a ski pass-through.

To make loading and unloading groceries and cargo easier when your hands are full, the AMG GT 4-Door’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The GS F doesn’t offer a power or hands-free opening trunk.


Heated windshield washer nozzles are standard on the AMG GT 4-Door to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The GS F doesn’t offer heated windshield washer nozzles.

Both the AMG GT 4-Door and the GS F have standard heated front seats. The AMG GT 4-Door also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the GS F.

On extremely cold winter days, the AMG GT 4-Door’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The GS F doesn’t offer a heated steering wheel.

The AMG GT 4-Door offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The GS F doesn’t offer a house-current electrical outlet.

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 GS F doesn’t offer an automated parking system.
