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 S7 doesn’t offer backup collision prevention brakes.

Both the CT6-V and the S7 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, lane departure warning systems, rearview cameras and available around view monitors.

Cadillac’s powertrain warranty covers the CT6-V 2 years and 20,000 miles longer than Audi covers the S7. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the S7 ends after only 4 years or 50,000 miles.

There are almost 3 times as many Cadillac dealers as there are Audi dealers, which makes it much easier should you ever need service under the CT6-V’s warranty.
