Safety Comparison

Over 200 people are killed each year when backed over by motor vehicles. The 7 Series offers an optional backup collision prevention system which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The S-Class doesn’t offer backup collision prevention brakes.

To help make backing safer, the 7 Series’ optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The S-Class doesn’t offer a cross-path warning system.

Both the 7 Series and the S-Class 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, daytime running lights, rearview cameras, driver alert monitors, available crash mitigating brakes, night vision systems, lane departure warning systems, blind spot warning systems and around view monitors.

Warranty Comparison

The 7 Series’ corrosion warranty is 8 years and unlimited miles longer than the S-Class’ (12/unlimited vs. 4/50,000).

BMW pays for scheduled maintenance on the 7 Series for 4 years and 50,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the S-Class.

There are over 12 percent more BMW dealers than there are Mercedes dealers, which makes it easier should you ever need service under the 7 Series’ warranty.

Tires and Wheels Comparison

For better ride, handling and brake cooling the 7 Series offers optional 21-inch wheels. The S-Class’ largest wheels are only 20-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 7 Series 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 S-Class.

Suspension and Handling Comparison

The 7 Series 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 S-Class doesn’t offer an active sway bar system.

For a smoother ride and more stable handling, the 7 Series’ wheelbase is 1.8 inches longer than on the S-Class (126.4 inches vs. 124.6 inches).

For better handling and stability, the track (width between the wheels) on the 7 Series is .4 inches wider in the front and 1.8 inches wider in the rear than on the S-Class.

The 750i xDrive handles at .88 G’s, while the S550 pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The 750i xDrive executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the S550 (25.4 seconds @ .75 average G’s vs. 26.5 seconds @ .7 average G’s).

Chassis Comparison

The BMW 7 Series may be more efficient, handle and accelerate better because it weighs about 400 to 500 pounds less than the Mercedes S-Class.

The front grille of the 7 Series uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The S-Class doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the 750i xDrive is quieter than the S550:

7 Series

Passenger Space Comparison

The 7 Series has 1.1 inches more front headroom and 1.4 inches more rear legroom than the S-Class.
