Safety

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the 6 Series Gran Turismo. But it costs extra on the E-Class Sedan.

A passive infrared night vision system optional on the 6 Series Gran Turismo 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 E-Class Sedan doesn’t offer a night vision system.

Both the 6 Series Gran Turismo and the E-Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors and available around view monitors.

Warranty

The 6 Series Gran Turismo’s corrosion warranty is 7 years longer than the E-Class Sedan’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the 6 Series Gran Turismo for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the E-Class Sedan.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the 6 Series Gran Turismo has a standard 210-amp alternator. The E-Class Sedan’s 180-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the 6 Series Gran Turismo has a standard 900-amp battery. The E-Class Sedan’s 850-amp battery isn’t as powerful.

Power ranks BMW 11th in initial quality, above the industry average. With 5 more problems per 100 vehicles, Mercedes is ranked 14th.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Mercedes vehicles. J.D. Power ranks BMW 8th in reliability, above the industry average. With 20 more problems per 100 vehicles, Mercedes is ranked 15th.

Engine

The 6 Series Gran Turismo’s 3.0 turbo 6 cyl. produces 94 more horsepower (335 vs. 241) and 57 lbs.-ft. more torque (330 vs. 273) than the E 300 Sedan’s standard 2.0 turbo 4 cyl.

Brakes and Stopping

For better stopping power the 6 Series Gran Turismo’s standard brake rotors are larger than those on the E-Class Sedan:

13.7 inches

13.5 inches

Rear Rotors

13.6 inches

11.8 inches

Tires and Wheels

The 6 Series Gran Turismo’s optional 245/35R20 front and 275/30R20 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 E-Class Sedan’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 6 Series Gran Turismo has standard 19-inch wheels. Smaller 18-inch wheels are standard on the E-Class Sedan. The 6 Series Gran Turismo’s optional 20-inch wheels are larger than the 19-inch wheels optional on the E-Class Sedan.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 6 Series Gran Turismo can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. Run-flat tires aren’t available on some tire packages on the E-Class Sedan.

Suspension and Handling

The 6 Series Gran Turismo 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 E-Class Sedan doesn’t offer an active sway bar system.

The rear suspension of the 6 Series Gran Turismo uses air springs for a smoother, controlled ride than the E-Class Sedan, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The 6 Series Gran Turismo offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Mercedes doesn’t offer an active suspension on the E-Class Sedan.

For a smoother ride and more stable handling, the 6 Series Gran Turismo’s wheelbase is 5.2 inches longer than on the E-Class Sedan (120.9 inches vs. 115.7 inches).

For better handling and stability, the track (width between the wheels) on the 6 Series Gran Turismo is 1.5 inches wider in the rear than the average track on the E-Class Sedan.

The 6 Series Gran Turismo’s front to rear weight distribution is more even (50.9% to 49.1%) than the E-Class Sedan’s (54.2% to 45.8%). This gives the 6 Series Gran Turismo more stable handling and braking.

Chassis

The front grille of the 6 Series Gran Turismo uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The E-Class Sedan doesn’t offer active grille shutters.

Passenger Space

The 6 Series Gran Turismo has 2 inches more front headroom, 2.2 inches more front shoulder room, .3 inches more rear headroom and 4.2 inches more rear legroom than the E-Class Sedan.

For enhanced passenger comfort on long trips the 6 Series Gran Turismo’s available rear seats recline. The E-Class Sedan’s rear seats don’t recline.

Ergonomics

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The 6 Series Gran Turismo has standard headlight washers to keep headlight output high. The E-Class Sedan doesn’t offer headlight washers.

The 6 Series Gran Turismo has standard heated front seats. Heated front seats cost extra on the E-Class Sedan. The 6 Series Gran Turismo also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the E-Class Sedan.
