Ford’s powertrain warranty covers the Mustang 1 year and 10,000 miles longer than Audi covers the S5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the S5 ends after only 4 years or 50,000 miles.

There are almost 10 times as many Ford dealers as there are Audi dealers, which makes it much easier should you ever need service under the Mustang’s warranty.

The Mustang has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The S5 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.
