Consumer Reports

Tires and Wheels Comparison

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 3 Series Sedan 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 3 Series Sedan offers an optional 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 Sedan’s suspension doesn’t offer adjustable shock absorbers.

The 320i handles at .92 G’s, while the E250 BlueTEC Sedan 4MATIC pulls only .85 G’s of cornering force in a Motor Trend skidpad test.

The 335i xDrive executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the E250 BlueTEC Sedan 4MATIC (25.6 seconds @ .75 average G’s vs. 27.1 seconds @ .63 average G’s).

Chassis Comparison

The BMW 3 Series Sedan may be more efficient, handle and accelerate better because it weighs about 600 to 700 pounds less than the Mercedes E-Class Sedan.

The 3 Series Sedan is 9.6 inches shorter than the E-Class Sedan, making the 3 Series Sedan easier to handle, maneuver and park in tight spaces.

Cargo Capacity Comparison

To allow full utilization of available cargo room, the 3 Series Sedan’s 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 3 Series Sedan (except 320i) offers an available 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.

Heated windshield washer nozzles are standard on the 3 Series Sedan to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The E-Class Sedan 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 3 Series Sedan offers available headlight washers to keep headlight output high. The E-Class Sedan doesn’t offer headlight washers.

Both the 3 Series Sedan and the E-Class Sedan offer optional heated front seats. The 3 Series Sedan 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.

Economic Advantages Comparison

Insurance will cost less for the 3 Series Sedan owner. The Complete Car Cost Guide estimates that insurance for the 3 Series Sedan will cost $3090 less than the E-Class Sedan over a five-year period.
