Compare the2025 McLaren 750SVS 2025 Porsche 911

The McLaren 750S 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.

Both the 750S 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, rearview cameras and available around view monitors.

The 750S comes with a full 3-year/unlimited-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The 911’s 50,000-mile basic warranty expires sooner.

McLaren pays for scheduled maintenance on the 750S for 2 years and unlimited miles longer than Porsche pays for maintenance for the 911 (3/unlimited vs. 1/10,000).

The 750S’ 4.0 turbo V8 produces 352 more horsepower (740 vs. 388) and 259 lbs.-ft. more torque (590 vs. 331) than the 911’s standard 3.0 turbo 6-cylinder. The 750S’ 4.0 turbo V8 produces 267 more horsepower (740 vs. 473) and 200 lbs.-ft. more torque (590 vs. 390) than the 911 S’ standard 3.0 turbo 6-cylinder. The 750S’ 4.0 turbo V8 produces 238 more horsepower (740 vs. 502) and 259 lbs.-ft. more torque (590 vs. 331) than the 911 GT3’s standard 4.0 DOHC 6-cylinder. The 750S’ 4.0 turbo V8 produces 100 more horsepower (740 vs. 640) than the 911 Turbo S’ standard 3.7 turbo 6-cylinder.

As tested in Motor Trend the McLaren 750S is faster than the Porsche 911 3.0 turbo 6-cylinder (automatics tested):

On the EPA test cycle the 750S gets better mileage than the 911 Coupe:

On the EPA test cycle the 750S gets better mileage than the 911 Cabriolet:

The 750S has 2.4 gallons more fuel capacity than the 911’s standard fuel tank (19 vs. 16.6 gallons), for longer range between fill-ups.

The 750S 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 750S’ standard brake rotors are larger than those on the 911:

The 750S has standard air brakes, which adjust the Spoiler automatically during high-speed braking in order to shorten stopping distances. The 911 doesn’t offer air brakes.

The 750S stops much shorter than the 911:

For better traction, the 750S has larger tires than the 911 (F:245/35R19 & R:305/30R20 vs. F:235/40R19 & R:295/35R20).

The 750S’ 245/35R19 front and 305/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the 911 Dakar’s standard 45 series front and 40 series rear tires.

The 750S offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Porsche doesn’t offer an active suspension on the 911.

The 750S 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 750S’ wheelbase is 8.6 inches longer than on the 911 (105.1 inches vs. 96.5 inches). The 750S’ wheelbase is 8.4 inches longer than on the 911 GT3 (105.1 inches vs. 96.7 inches).

For better handling and stability, the track (width between the wheels) on the 750S is 3.3 inches wider in the front and 2.5 inches wider in the rear than the average track on the 911.

The 750S’ front to rear weight distribution is more even (41.2% to 58.8%) than the 911’s (39.5% to 60.5%). This gives the 750S more stable handling and braking.

The 750S handles at 1.13 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.

The 750S executes Motor Trend’s “Figure Eight” maneuver quicker than the 911 T Coupe (22.5 seconds @ .97 average G’s vs. 23.3 seconds @ .86 average G’s).

The 750S is 10.4 inches shorter in height than the 911, making the 750S much easier to wash and garage and drive (lower center of gravity).

The 750S’ standard power retractable hardtop allows a seamless transition from an open car, to a completely sealed coupe. The 911 doesn’t offer a retractable hardtop.

The 750S has a much larger trunk than the 911 Coupe with its rear seat up (12.7 vs. 4.8 cubic feet).

The 750S Spider has a much larger trunk with its top down than the 911 Cabriolet with its top down (7.3 vs. 4.8 cubic feet).

With its coupe body style and remote trunk release lockout, the 750S offers cargo security. The 911’s non-lockable folding seat defeats cargo security.

If the windows are left open on the 750S 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 also lower the windows the same way. The driver of the 911 can only operate the windows from inside the vehicle, with the ignition on.

In case of a sudden change of weather, the 750S Convertible has a standard remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. On a hot day the 750S Convertible has a standard remote opening feature, to lower the top from outside. The 911 doesn’t offer a remote top, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.

The 750S has standard Keyless Entry and Start that allows you to unlock the doors from either outside door handle and start the engine, all without removing the key from the pocket or purse. The 911 GT3 doesn’t offer Comfort Access.
