Safety Comparison

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 BMW M4 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 BMW M4 doesn’t offer height-adjustable seat belts.

Both the GranTurismo and the M4 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 560 to 820 pounds more than the BMW M4. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Tires and Wheels Comparison

For better traction and acceleration, the GranTurismo has larger standard rear tires than the M4 (285/35R20 vs. 275/40R18). The GranTurismo MC’s rear tires are larger than the largest rear tires available on the M4 (295/35R20 vs. 275/40R18).

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 M4’s standard 40 series tires.

For better ride, handling and brake cooling the GranTurismo has standard 20-inch wheels. Smaller 18-inch wheels are standard on the M4. The M4’s largest wheels are only 19-inches.

Suspension and Handling Comparison

For a smoother ride and more stable handling, the GranTurismo’s wheelbase is 5.1 inches longer than on the M4 (115.8 inches vs. 110.7 inches).

For better maneuverability, the GranTurismo’s turning circle is 4.9 feet tighter than the M4’s (35.1 feet vs. 40 feet).

Ergonomics Comparison

The GranTurismo’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The M4 doesn’t offer an easy entry system.

The GranTurismo’s front power windows open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The M4’s passenger windows don’t open or close automatically.
