Safety

The 6 Series Gran Turismo has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The E-Class Wagon doesn’t offer a whiplash protection system.

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 Wagon doesn’t offer a night vision system.

Both the 6 Series Gran Turismo and the E-Class Wagon 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, all wheel drive, 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 Wagon’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 Wagon.

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 Wagon’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 Wagon’s 850-amp battery isn’t as powerful.

Fuel Economy and Range

On the EPA test cycle the 640i Gran Turismo gets better fuel mileage than the E 450 4MATIC Wagon (20 city/28 hwy vs. 19 city/26 hwy).

Regenerative brakes improve the 6 Series Gran Turismo’s fuel efficiency by converting inertia back into energy instead of wasting it. The E-Class Wagon doesn’t offer a regenerative braking system.

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 Wagon’s optional 40 series 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 Wagon. The 6 Series Gran Turismo’s optional 20-inch wheels are larger than the 19-inch wheels optional on the E-Class Wagon.

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 Wagon doesn’t offer an active sway bar system.

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 Wagon.

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 Wagon (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 .6 inches wider in the front and 1.2 inches wider in the rear than on the E-Class Wagon.

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 Wagon doesn’t offer active grille shutters.

Passenger Space

The 6 Series Gran Turismo has 1.9 inches more front headroom, 2.2 inches more front shoulder room and 4.6 inches more rear legroom than the E-Class Wagon.

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

Cargo Capacity

The 6 Series Gran Turismo has a larger cargo volume with its rear seat folded than the E-Class Wagon with its rear seat folded (65 vs. 64 cubic feet).

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 Wagon doesn’t offer headlight washers.

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