Safety Comparison

Both the 5 Series and the E Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, front seatbelt pretensioners, plastic fuel tanks, four wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The 5 Series’ corrosion warranty is 8 years and unlimited miles longer than the E Class Sedan’s (12/unlimited vs. 4/50,000).

BMW pays for scheduled maintenance on the 5 Series for 4 years and 50,000 miles. BMW will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. Mercedes doesn’t pay scheduled maintenance for the E Class Sedan.

There are over 12 percent more BMW dealers than there are Mercedes dealers, which makes it easier to get service under the 5 Series’ warranty.

Reliability Comparison

The battery on the 5 Series is in the trunk, which protects it from hot underhood temperatures which can degrade battery life. By keeping the 5 Series’ battery 20 to 30 degrees cooler, its life is increased by years. The E Class Sedan’s battery is in the hot engine compartment.

J.D. Power and Associates’ surveys of the owners of three-year-old cars provide the long-term dependability statistics that show that BMW vehicles are more reliable than Mercedes vehicles. J.D. Power ranks BMW 15th in reliability, above the industry average. With 18 more problems per 100 vehicles, Mercedes is ranked 17th.

Car and Driver

Tires and Wheels Comparison

The 550i Sedan’s optional 245/35R19 front and 275/30R19 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 Sport’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 550i Sedan offers optional 19 inch wheels. The E Class Sedan’s largest wheels are only 18 inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 5 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 Sedan doesn’t offer run-flat tires.

Suspension and Handling Comparison

The 5 Series Sedan 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 Sedan.

The 5 Series Sedan handles at .90 G’s, while the E350 Sedan pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

Chassis Comparison

The BMW 5 Series may be more efficient, handle and accelerate better because it weighs up to about 300 pounds less than the Mercedes E Class Sedan.

As tested by Car and Driver while cruising at 70 MPH, the interior of the 550i Sedan is quieter than the E350 Sedan (66 vs. 69 dB).

Passenger Space Comparison

The 5 Series Sedan has 1.2 inches more front headroom, .2 inches more front legroom, .2 inches more rear legroom and .3 inches more rear shoulder room than the E Class Sedan.

Cargo Capacity Comparison

To allow full utilization of available cargo room, the 5 Series’ trunk lid uses concealed beam hinges that don’t intrude into the trunk. The E Class Sedan’s useful trunk space is reduced by its intrusive beam hinge.

Ergonomics Comparison

The 5 Series offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The E Class Sedan doesn’t offer a heads-up display.

When the 5 Series is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The E Class Sedan’s mirror doesn’t automatically adjust for backing.

To help keep rear passengers entertained, the 5 Series offers optional rear seat controls for the radio. The E Class Sedan doesn’t offer rear seat audio controls.
