Jaguar XK leaves the lineup

Production of the Jaguar XK stretched from 1996 with the XK8 and will wrap up as the final 50 limited edition XK models roll off the assembly line this summer. The farewell XKs will be branded as "Final Fifty Limited Edition" cars, and will carry the same specification as the current XKR model, along with some added features that celebrate the history of Jaguar and the evolution of the brand's grand touring coupes and convertibles. Under the hood, a supercharged 510-hp 5.0-liter V8 is capable of bringing the XK to 60 mph in 4.6 seconds according to Jag, and an active exhaust system helps ensure the engine note remains prominent.

The Miura was undeniably gorgeous, but wasn't yet on the same level as the Ferraris in terms of performance.
