Safety Comparison

A passive infrared night vision system optional on the 6 Series 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 Coupe doesn’t offer a night vision system.

Both the 6 Series and the E-Class Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

Tires and Wheels Comparison

For better traction, the 6 Series has larger standard tires than the E-Class Coupe (245/45R18 vs. 235/40R18). The M6’s tires are larger than the largest tires available on the E-Class Coupe (F:265/40R19 & R:295/35R19 vs. F:235/40R18 & R:255/35R18).

For better ride, handling and brake cooling the 6 Series offers optional 20-inch wheels. The E-Class Coupe’s largest wheels are only 19-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 6 Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The E-Class Coupe doesn’t offer run-flat tires.

Suspension and Handling Comparison

The 6 Series offers an available 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 Coupe.

The 6 Series 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 M6’s wheelbase is 3.5 inches longer than on the E-Class Coupe (112.2 inches vs. 108.7 inches).

Cargo Capacity Comparison

To allow full utilization of available cargo room, the 6 Series’ 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.

Ergonomics Comparison

The 6 Series offers an optional heads-up display which projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The E-Class Coupe doesn’t offer a heads-up display.

Heated windshield washer nozzles are standard on the 6 Series to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The E-Class Coupe doesn’t offer heated windshield washer nozzles.

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 has standard headlight washers to keep headlight output high. The E-Class Coupe doesn’t offer headlight washers.

Recommendations Comparison

J.D. Power and Associates rated the 6 Series first among midsize premium sporty cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The E-Class Coupe isn’t in the top three.
