Compare the2025 Porsche 911VS 2024 Maserati GranTurismo

To maximize occupant safety, the front seat shoulder belts of the Porsche 911 have pretensioners to eliminate dangerous slack in the event of a collision. The Maserati GranTurismo doesn’t offer pretensioners.

A passive infrared night vision system optional on the 911 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The GranTurismo doesn’t offer a night vision system.

The 911’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GranTurismo.

Both the 911 and GranTurismo offer rear cross-traffic warning, but the 911 with Rear Cross Traffic Alert also has Rear Cross Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The GranTurismo’s Rear Cross Path doesn’t automatically brake.

Both the 911 and the GranTurismo 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, rearview cameras, available crash mitigating brakes, blind spot warning systems and around view monitors.

The 911’s corrosion warranty is 8 years and unlimited miles longer than the GranTurismo’s (12/unlimited vs. 4/50,000).

There are over 83 percent more Porsche dealers than there are Maserati dealers, which makes it much easier should you ever need service under the 911’s warranty.

J.D. Power and Associates rated the 911 second among premium sporty cars in their 2024 Initial Quality Study. The GranTurismo isn’t in the top three in its category.

The 911 has more powerful engines than the GranTurismo:

As tested in Car and Driver the 911 GT3 4.0 DOHC 6-cylinder is faster than the GranTurismo Trofeo (automatics tested):

The flat cylinder configuration of the boxer engine in the 911 lowers its center of gravity, enhancing handling stability. The GranTurismo doesn’t offer a boxer engine configuration.

Regenerative brakes improve the 911 GTS’ fuel efficiency by converting inertia back into energy instead of wasting it. The GranTurismo doesn’t offer a regenerative braking system.

The 911’s optional fuel tank has 3.6 gallons more fuel capacity than the GranTurismo (22.1 vs. 18.5 gallons).

The 911 offers a manual transmission for better acceleration, control and sportiness. The GranTurismo doesn’t offer a manual transmission.

The 911 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The GranTurismo doesn’t offer an SMG.

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

The 911 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 GranTurismo doesn’t offer ceramic brake rotors.

The 911 stops much shorter than the GranTurismo:

For better traction, the 911 GT3 RS’ optional tires are larger than the largest tires available on the GranTurismo (F:275/30R20 & R:335/30R21 vs. F:265/30R20 & R:295/30R21).

The 911 (except Base/GT3) 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 GranTurismo doesn’t offer an active sway bar system.

The 911 GT3 handles at 1.17 G’s, while the GranTurismo Trofeo pulls only .97 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the 911 GT3’s turning circle is 6.6 feet tighter than the GranTurismo’s (34.1 feet vs. 40.7 feet). The 911’s turning circle is 4 feet tighter than the GranTurismo’s (36.7 feet vs. 40.7 feet).

The Porsche 911 may be more efficient, handle and accelerate better because it weighs about 350 to 1000 pounds less than the Maserati GranTurismo.

The 911 is 1 foot, 4.7 inches shorter than the GranTurismo Modena, making the 911 easier to handle, maneuver and park in tight spaces.

The 911’s standard rear seats fold to accommodate long and bulky cargo. The GranTurismo doesn’t offer folding rear seats, only a ski pass-through.

The 911’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The GranTurismo doesn’t offer an easy entry system.

To improve rear visibility by keeping the rear window clear, the 911 (except Cabriolet/GT3) offers an optional rear wiper. The GranTurismo doesn’t offer a rear wiper.

The 911 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the GranTurismo.

The 911 (except Manual/GT3)’s optional Active Parking Support can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Optional Remote ParkAssist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The GranTurismo doesn’t offer an automated parking system.

The Porsche 911 comes in coupe and convertible bodystyles; the Maserati GranTurismo isn’t available as a convertible.

The 911 is available in both rear-wheel drive and all-wheel drive configurations. The GranTurismo doesn’t offer a two-wheel drive configuration.

J.D. Power and Associates rated the 911 second among premium sporty cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The GranTurismo isn’t in the top three.
