The AMG CLS’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GS F doesn’t offer pre-crash pretensioners.

The AMG CLS has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The GS F doesn’t offer all-wheel drive.

The AMG CLS offers an optional Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The GS F 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 AMG CLS and the GS F have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available lane departure warning systems.

The Mercedes AMG CLS weighs 413 pounds more than the Lexus GS F. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

On the EPA test cycle the AMG CLS 53 gets better fuel mileage than the GS F (21 city/27 hwy vs. 16 city/24 hwy).

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

In heavy traffic or at stoplights the AMG 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 GS F doesn’t offer an automatic engine start/stop system.

The AMG CLS has 3.7 gallons more fuel capacity than the GS F (21.1 vs. 17.4 gallons), for longer range between fill-ups.

The AMG CLS’ optional 275/30R19 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the GS F’s 35 series tires.

For better ride, handling and brake cooling the AMG CLS offers optional 20-inch front wheels. The GS F’s largest wheels are only 19-inches.

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

The front and rear suspension of the AMG CLS uses air springs for a smoother, controlled ride than the GS F, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The AMG CLS has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The AMG 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 GS F doesn’t offer a load leveling suspension.

The AMG 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 GS F doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the AMG CLS’ wheelbase is 3.5 inches longer than on the GS F (115.7 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the AMG CLS is 3.6 inches wider in the front and 3.1 inches wider in the rear than on the GS F.

The design of the Mercedes AMG CLS amounts to more than styling. The AMG CLS has an aerodynamic coefficient of drag of .26 Cd. That is significantly lower than the GS F (.33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the AMG CLS get better fuel mileage.
