Both the Thunderbird and the XK8 have standard driver and passenger side airbags, front side-impact airbags, head airbags, front seatbelt pretensioners, Isofix Child Safety Seat Latches, four wheel antilock brakes and available traction control.
There are over 27 times as many Ford dealers as there are Jaguar dealers, which makes it much easier to get service under the Thunderbird’s warranty.
The Thunderbird 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 XK8 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.
The XKR adds an expensive supercharger, for added power. This extra component turns much faster than the engine, and is an additional component to maintain.
The battery on the Thunderbird is in the trunk, which protects it from hot underhood temperatures which can degrade battery life. By keeping the Thunderbird’s battery 20 to 30 degrees cooler, its life is increased by years. The XK8’s battery is in the hot engine compartment.
The Thunderbird gets better fuel mileage than the XK8 with its standard engine (17 city/23 hwy vs. 16 city/22 hwy).
The Thunderbird with its standard antilock brakes stops shorter than the XK8 with antilock brakes:
