The XJ Supersport is a diesel? It’s fast. Very fast.

The 4.4 liter diesel engine will deliver a total of 375bhp and a peak torque of more than 600lb.-ft. The sprint from 0 to 60 mph will be made quicker than the supercharged XJ and will return 40mpg. Same engine is also rumored to be offered in the Jaguar XF.

It hits 60 in 4.7 seconds, only 0.01 of a second behind the Jaguar XKR sports car. Oh, that 40 mpg figure actually drops to 24 mpg in the Supersport, but it’s still impressive for a sports car today.

It also has a high-tech interior. The dashboard is a dynamically changing TFT flat-screen panel, as described in a CNET review.

All the graphics shown there are dynamic and context-sensitive, so the visuals change, depending on what the driver requires. Receive new directions from the sat-nav, for example, and the fuel gauge is temporarily replaced by a full-colour map showing new directions. Access the engine computer and the rev counter is swapped for a colour menu that gives you access to vehicle setup functions.

It’s so fast, despite being fuel efficient, the police even have a model. Actually, the police model gets the smaller 40mpg engine but it still runs under 6 seconds to 60:

The Jaguar XF Diesel S is powered by a 3.0-liter AJ-V6D Gen III diesel engine that delivers 275 hp. The Diesel S accelerates from 0-60mph in just 5.9 seconds, while top speed is limited to 155 mph.

Send Ford an email and tell them to take the lessons learned from Jaguar and offer diesel options in America. What are they waiting for?
