Compare the2025 Ford Mustang GTDVS 2025 Porsche 911

The Ford Mustang GTD has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The 911 doesn’t offer knee airbags.

The Mustang GTD has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 911 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.

Both the Mustang GTD and the 911 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, lane departure warning systems, rearview cameras and driver alert monitors.

The Ford Mustang GTD weighs 474 to 1287 pounds more than the Porsche 911. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Ford’s powertrain warranty covers the Mustang GTD 1 year and 10,000 miles longer than Porsche covers the 911. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the 911 ends after only 4 years or 50,000 miles.

There are over 14 times as many Ford dealers as there are Porsche dealers, which makes it much easier should you ever need service under the Mustang GTD’s warranty.

The Mustang GTD has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The 911 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

The Mustang GTD’s 5.2 supercharged V8 produces 427 more horsepower (815 vs. 388) and 333 lbs.-ft. more torque (664 vs. 331) than the 911’s standard 3.0 turbo 6-cylinder. The Mustang GTD’s 5.2 supercharged V8 produces 342 more horsepower (815 vs. 473) and 274 lbs.-ft. more torque (664 vs. 390) than the 911 S’ standard 3.0 turbo 6-cylinder. The Mustang GTD’s 5.2 supercharged V8 produces 313 more horsepower (815 vs. 502) and 333 lbs.-ft. more torque (664 vs. 331) than the 911 GT3’s standard 4.0 DOHC 6-cylinder. The Mustang GTD’s 5.2 supercharged V8 produces 175 more horsepower (815 vs. 640) and 74 lbs.-ft. more torque (664 vs. 590) than the 911 Turbo S’ standard 3.7 turbo 6-cylinder.

As tested in Car and Driver the Ford Mustang GTD is faster than the Porsche 911 3.0 turbo 6-cylinder (automatics tested):

The Mustang GTD has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The 911 doesn’t offer a cap-less fueling system.

For better stopping power the Mustang GTD’s brake rotors are larger than those on the 911:

The Mustang GTD stops much shorter than the 911:

For better traction, the Mustang GTD has larger tires than the 911 (F:325/30R20 & R:345/30R20 vs. F:235/40R19 & R:295/35R20). The Mustang GTD’s tires are larger than the largest tires available on the 911 (F:325/30R20 & R:345/30R20 vs. F:275/30R20 & R:335/30R21).

The Mustang GTD’s tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the 911 Dakar’s standard 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the Mustang GTD has standard 20-inch wheels. Smaller 19-inch front wheels are standard on the 911.

The Mustang GTD has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The 911 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Mustang GTD’s wheelbase is 10.6 inches longer than on the 911 (107.1 inches vs. 96.5 inches).

For better handling and stability, the track (width between the wheels) on the Mustang GTD is 5.1 inches wider in the front and 6.7 inches wider in the rear than the average track on the 911.

The Mustang GTD’s front to rear weight distribution is more even (50% to 50%) than the 911’s (39.5% to 60.5%). This gives the Mustang GTD more stable handling and braking.

The Mustang GTD handles at 1.17 G’s, while the 911 Carrera 4 GTS Coupe pulls only 1.03 G’s of cornering force in a Car and Driver skidpad test.

As tested by Car and Driver, the interior of the Mustang GTD is quieter than the 911 GT3:

The Mustang GTD has 2.3 inches more front legroom and 3.7 inches more front shoulder room than the 911.

The Mustang GTD has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 911 doesn’t offer a remote starting system.

On a hot day the Mustang GTD’s driver can lower all the windows from a distance using the keyless remote. The driver of the 911 can only operate the windows from inside the vehicle, with the ignition on.

The Mustang GTD has standard Intelligent Access that allows you to unlock the doors from either outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. The 911 GT3 doesn’t offer Comfort Access.

The Mustang GTD’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The 911’s cruise control switches are unlit, making them difficult to find at night and operate safely.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Mustang GTD has standard extendable sun visors. The 911 doesn’t offer extendable visors.

The Ford Mustang outsold the Porsche 911 by almost three to one during 2024.
