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 Mercedes E-Class Coupe doesn’t offer height-adjustable seat belts.
Both the GranTurismo and the E-Class Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and front parking sensors.
The GranTurismo’s 4.7 DOHC V8 produces 125 more horsepower (454 vs. 329) and 30 lbs.-ft. more torque (384 vs. 354) than the E400 Coupe’s standard 3.0 turbo V6. The GranTurismo’s 4.7 DOHC V8 produces 52 more horsepower (454 vs. 402) than the E550 Coupe’s standard 4.7 turbo V8.
The GranTurismo has 1.6 gallons more fuel capacity than the E-Class Coupe (19 vs. 17.4 gallons), for longer range between fill-ups.
For better stopping power the GranTurismo’s standard brake rotors are larger than those on the E-Class Coupe:

Front Rotors |
13 inches |
12.7 inches |
Rear Rotors |

11.8 inches |
For better traction, the GranTurismo has larger standard tires than the E-Class Coupe (F:245/35R20 & R:285/35R20 vs. F:235/40R18 & R:255/35R18). The GranTurismo MC’s tires are larger than the largest tires available on the E-Class Coupe (F:255/35R20 & R:295/35R20 vs. F:235/40R18 & R:255/35R18).
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 E-Class Coupe’s standard 40 series front tires.
For better ride, handling and brake cooling the GranTurismo has standard 20-inch wheels. Smaller 18-inch wheels are standard on the E-Class Coupe. The E-Class Coupe’s largest wheels are only 19-inches.
The GranTurismo has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The E-Class Coupe’s suspension doesn’t offer adjustable shock absorbers.
For a smoother ride and more stable handling, the GranTurismo’s wheelbase is 7.1 inches longer than on the E-Class Coupe (115.8 inches vs. 108.7 inches).
For better handling and stability, the track (width between the wheels) on the GranTurismo is 1.6 inches wider in the front and 2 inches wider in the rear than on the E-Class Coupe.
The GranTurismo has 5 cubic feet more passenger volume than the E-Class Coupe (86 vs. 81).
The GranTurismo has 2.2 inches more front headroom, .1 inches more front shoulder room, .3 inches more rear headroom and 3.2 inches more rear shoulder room than the E-Class Coupe.
To allow full utilization of available cargo room, the GranTurismo’s trunk lid uses gas strut supported hinges that don’t intrude into the trunk. The E-Class Coupe’s useful trunk space is reduced by its intrusive beam hinge.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The GranTurismo has standard headlight washers to keep headlight output high. The E-Class Coupe doesn’t offer headlight washers.
