For enhanced safety, the front and rear seat shoulder belts of the Maserati GranTurismo have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Porsche 911 doesn’t offer pretensioners for the rear seat belts.
For enhanced safety, the front seat shoulder belts of the Maserati GranTurismo are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Porsche 911 doesn’t offer height-adjustable seat belts.
Both the GranTurismo and the 911 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.
The Maserati GranTurismo weighs 607 to 1104 pounds more than the Porsche 911. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The GranTurismo has 5.8 gallons more fuel capacity than the 911 RWD/Turbo/GT3’s standard fuel tank (22.7 vs. 16.9 gallons), for longer range between fill-ups.
For better traction, the GranTurismo has larger tires than the 911 (F:255/35R20 & R:295/35R20 vs. F:235/40R19 & R:285/35R19). The GranTurismo’s front tires are larger than the largest tires available on the 911 (255/35R20 vs. 245/35R20).
The GranTurismo’s tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the 911’s standard 40 series front tires.
For better ride, handling and brake cooling the GranTurismo has standard 20-inch wheels. Smaller 19-inch wheels are standard on the 911.
For a smoother ride and more stable handling, the GranTurismo’s wheelbase is 19.3 inches longer than on the 911 (115.8 inches vs. 96.5 inches).
For better handling and stability, the track (width between the wheels) on the GranTurismo is 1.9 inches wider in the front and 2.1 inches wider in the rear than the average track on the 911.
The GranTurismo’s front to rear weight distribution is more even (48.5% to 51.5%) than the 911’s (39.3% to 60.7%). This gives the GranTurismo more stable handling and braking.
The GranTurismo has 1 inch more front headroom, 3.4 inches more front shoulder room, 4.8 inches more rear headroom, 5.1 inches more rear legroom and 3.8 inches more rear shoulder room than the 911 Coupe.
The GranTurismo has a much larger trunk than the 911 Coupe with its rear seat up (9.2 vs. 4.76 cubic feet).
The GranTurismo’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the 911.
The GranTurismo has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable. The 911 doesn’t offer a rear seat center armrest.
For greater rear passenger comfort, the GranTurismo has standard rear a/c vents to keep rear occupants more comfortable. The 911 doesn’t offer rear vents.
