Safety

The CLS offers an optional Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The G80 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the CLS and the G80 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems and rear cross-path warning.

Regenerative brakes improve the CLS’ fuel efficiency by converting inertia back into energy instead of wasting it. The G80 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the CLS’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The G80 doesn’t offer an automatic engine start/stop system.

Transmission

A nine-speed automatic is available on the Mercedes CLS, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the G80.

Brakes and Stopping

For better stopping power the CLS’ brake rotors are larger than those on the G80:

14.2 inches

13.6 inches

Rear Rotors

The CLS’ standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the G80 3.8 are solid, not vented.

The CLS stops much shorter than the G80:

Car and Driver

Tires and Wheels

For better traction and acceleration, the CLS has larger rear tires than the G80 (275/35R19 vs. 245/45R18).

The CLS’ 245/40R19 front and 275/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the G80 3.8’s standard 45 series tires.

For better ride, handling and brake cooling the CLS 450 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the G80 3.8. The CLS’ optional 20-inch wheels are larger than the 19-inch wheels optional on the G80.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the CLS can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The G80 doesn’t offer run-flat tires.

Suspension and Handling

The CLS’ drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The G80 doesn’t offer drift compensation steering.

The CLS 450 4MATIC handles at .93 G’s, while the G80 AWD pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

Cargo Capacity

The CLS’ standard rear seats fold to accommodate long and bulky cargo. The G80 doesn’t offer folding rear seats, only a ski pass-through.

Ergonomics

Unlike the driver-only memory system in the G80, the CLS has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The CLS’ standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the G80.

If the windows are left open on the CLS the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the G80 can only operate the windows from inside the vehicle, with the ignition on.

Optional air conditioned seats in the CLS keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The G80 only offers an air-conditioned driver’s seat.

The CLS offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The G80 doesn’t offer a house-current electrical outlet.

The CLS’ optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The G80 doesn’t offer an automated parking system.
