The 3 Series Sedan’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The E-Class Sedan doesn’t offer launch control.

The 3 Series Sedan’s optional 225/35R20 front and 255/30R20 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 Sedan’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 3 Series Sedan offers optional 20-inch wheels. The E-Class Sedan’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 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. Run-flat tires aren’t available on some tire packages on the E-Class Sedan.

The 3 Series Sedan’s front to rear weight distribution is more even (51.5% to 48.5%) than the E-Class Sedan’s (54.2% to 45.8%). This gives the 3 Series Sedan more stable handling and braking.

For better maneuverability, the 3 Series Sedan’s turning circle is .8 feet tighter than the E-Class Sedan’s (37.4 feet vs. 38.2 feet).

The BMW 3 Series Sedan may be more efficient, handle and accelerate better because it weighs about 150 to 200 pounds less than the Mercedes E-Class Sedan.

The 3 Series Sedan is 8.1 inches shorter than the E-Class Sedan, making the 3 Series Sedan easier to handle, maneuver and park in tight spaces.

The front grille of the 3 Series Sedan 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 Sedan doesn’t offer active grille shutters.
