The new Jaguar XK has new 3.0 Litre V6 Diesel engine, new exterior and a redesigned interior.
The range comprises three models: the XK, XK Portfolio and supercharged XKR, and each are available in Coupe or Convertible body style.
The new 510 PS 5.0 Litre AJ-V8 GEN III R supercharged engine is said to be Jaguar's most powerful and efficient ever.
The new XF range are available with the naturally aspirated version of the new 5.0-litre petrol V8 and the new 3.0-litre V6 diesel engines (in two versions -500 and 600Nm).
Extras include a 7-inch Touch-screen, Portable Audio Interface, Driver Information Centre and the industry-leading JaguarDrive Selector used to control the all-new ZF 6HP28 six speed automatic transmission.
According to their press release, the new XF Diesel S model has a powerful 275PS engine and goes from 0-60mph speed in just 5.9 seconds. Available as Premium Luxury and Portfolio models. It was interesting to note that the maximum speed is electronically limited to 155mph.
If you are worried about the green credential (if you really are, why don't you drive a Prius) the average fuel consumption in both models is 42.0mpg and has a CO2 emissions rating of only 179g/km.
The new XFR - XF's new sporting flagship model, has two new generation 5.0 litre V8 petrol engines that goes from 0-60mph in 4.7 seconds. The AJ-V6D Gen III engine - available in either 240PS/500Nm form or 275PS/600Nm 'S' features parallel sequential turbochargers to help deliver the high levels of power and torque. The engine is coupled with a six-speed ZF 6HP28 automatic transmission.
Of course you don't buy a Jaguar just to drive fast. There's the comfort and craftsmanship. The new Jaguar cars offer a wider choice of veneers and trim colours. For audiophiles, a Bowers and Wilkins 440W surround sound system with portable audio interface and DAB radio is also included.
The new XK and XF range will be on sale from March 2009.
