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.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes CLS higher (6 out of 10) than the Genesis G80 (3 to 5). This means the CLS produces up to 23.4 pounds less smog-producing pollutants than the G80 every 15,000 miles.

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

The CLS’ standard 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. The CLS’ optional 245/35R20 front and 275/30R20 rear tires have a lower 35 series front and 30 series rear profile than the G80’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the CLS 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 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The CLS’ height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The G80 doesn’t offer a load leveling suspension.

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.

The CLS 450 4MATIC executes Motor Trend’s “Figure Eight” maneuver quicker than the G80 5.0 (25.8 seconds @ .72 average G’s vs. 26.7 seconds @ .7 average G’s).

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.

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, starting, stopping and changing direction automatically. The G80 doesn’t offer an automated parking system.

J.D. Power and Associates rated the CLS second among midsize premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The G80 isn’t in the top three.
