Over 200 people are killed each year when backed over by motor vehicles. The CT6-V has standard Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The AMG CLS doesn’t offer backup collision prevention brakes.

An active infrared night vision system standard on the CT6-V helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The AMG CLS doesn’t offer a night vision system.

Both the CT6-V and the AMG CLS 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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

Cadillac’s powertrain warranty covers the CT6-V 2 years and 20,000 miles longer than Mercedes covers the AMG CLS. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the AMG CLS ends after only 4 years or 50,000 miles.

The CT6-V’s corrosion warranty is 1 year longer than the AMG CLS’ (6 vs. 5 years).

There are over 2 times as many Cadillac dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the CT6-V’s warranty.

An engine control system that can shut down some of the engine’s cylinders helps improve the CT6-V’s fuel efficiency. The AMG CLS doesn’t offer a system that can shut down part of the engine.

The CT6-V has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The AMG CLS doesn’t offer a cap-less fueling system.

For better ride, handling and brake cooling the CT6-V has standard 20-inch wheels. Smaller 19-inch wheels are standard on the AMG CLS. The AMG CLS’ largest wheels are only 20-inches in the front and 19-inches in the rear.

The CT6-V has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the AMG CLS; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the AMG CLS don’t have a run-flat feature, either.

The CT6-V’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The AMG CLS does not have an oil pressure gauge.

A power rear sunshade and manual rear side window sunshades are standard in the CT6-V to help block heat and glare for the rear passengers. The AMG CLS doesn’t offer rear side window sunshades.
