Safety

The CLS has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The K900 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the CLS and the K900 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, around view monitors and rear cross-path warning.

Warranty

The CLS’ 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the K900 runs out after 100,000 miles.

Engine

The AMG CLS 53’s standard 3.0 turbo 6 cyl. hybrid produces 64 more horsepower (429 vs. 365) and 8 lbs.-ft. more torque (384 vs. 376) than the K900’s 3.3 turbo V6.

Regenerative brakes improve the CLS’ fuel efficiency by converting inertia back into energy instead of wasting it. The K900 doesn’t offer a regenerative braking 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 K900.

Brakes and Stopping

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 K900 are solid, not vented.

Tires and Wheels

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 K900’s standard 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the CLS offers optional 20-inch wheels. The K900’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 CLS can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The K900 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 K900 doesn’t offer drift compensation steering.

Chassis

The CLS is 4.9 inches shorter than the K900, making the CLS easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The CLS’ standard rear seats fold to accommodate long and bulky cargo. The K900 doesn’t offer folding rear seats, only a ski pass-through.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Kia. J.D. Power ranks Mercedes 6th in service department satisfaction (above the industry average). With a 42% lower rating, Kia is ranked 18th.

Ergonomics

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 K900 doesn’t offer an automated parking system.

Model Availability

The CLS is available in both rear-wheel drive and all-wheel drive configurations. The K900 doesn’t offer a two-wheel drive configuration.

Recommendations

The Mercedes CLS outsold the Kia K900 by almost three to one during the 2018 model year.
