Consumer Reports

Tires and Wheels

For better ride, handling and brake cooling the LS Series has standard 19-inch wheels. Smaller 18-inch wheels are standard on the E-Class Sedan. The LS Series’ optional 20-inch wheels are larger than the 19-inch wheels optional on the E-Class Sedan.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the LS 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 E-Class Sedan.

Suspension and Handling

The LS Series F-Sport 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 E-Class Sedan doesn’t offer an active sway bar system.

For a smoother ride and more stable handling, the LS Series’ wheelbase is 7.3 inches longer than on the E-Class Sedan (123 inches vs. 115.7 inches).

For better handling and stability, the average track (width between the wheels) on the LS Series is .9 inches wider in the front and 1.1 inches wider in the rear than the average track on the E-Class Sedan.

The LS Series’ front to rear weight distribution is more even (51% to 49%) than the E-Class Sedan’s (54.2% to 45.8%). This gives the LS Series more stable handling and braking.

For better maneuverability, the LS Series’ turning circle is 1.4 feet tighter than the E-Class Sedan’s (36.8 feet vs. 38.2 feet).


The LS Series uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The E-Class Sedan doesn’t offer active noise cancellation.

Passenger Space

The LS Series has 1 inch more front shoulder room and 2.7 inches more rear legroom than the E-Class Sedan.

For enhanced passenger comfort on long trips the LS Series’ available rear seats recline. The E-Class Sedan’s rear seats don’t recline.

Cargo Capacity

Servicing Ease

Consumer Reports rated the LS Series’ headlight performance “Very Good,” a higher rating than the E-Class Sedan’s headlights, which were rated “Poor.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The LS Series offers available headlight washers to keep headlight output high. The E-Class Sedan doesn’t offer headlight washers.

The LS Series has standard heated front seats. Heated front seats cost extra on the E-Class Sedan. The LS Series 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.

The LS Series has standard front air conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The E-Class Sedan doesn’t offer air-conditioned seats in the rear.
