The hunt for the Jaguar XF-R is now over. Engine details and plenty of pictures bearing the 5.0-litre powered British cat have been revealed ahead of its Detroit debut.

Official pictures and details of the new 2010 Jaguar XF-R have finally emerged. The executive British cat was designed to take on cars like the Audi RS6, BMW M5 and Mercedes-Benz E63/ CLS 63 AMG.

In order to play at this level Jaguar has provided a potent engine for the XF-R in the form of a 5.0-litre V8 with a whirling supercharger plugged into it plus an uprated 6-speed automatic gearbox. The engine produces 510hp (380kW) and 625Nm. In comparison the previous generation S Type R, the XF-R's spiritual predecessor, made 399hp (298kW) from its 4.2-litre supercharged motor. For this power the XF-R gives back a 0 - 60mph time of 4.7 seconds. Jaguar also did a 0 - 100km/h (62 mph) run which came back as 4.9 seconds on the clock. A combined fuel economy of 12.5l/100km (18.8mpg US) is stated by Jaguar.

In terms of specification Jaguar did not skimp on features for their new top-of-the-range XF. Wheels are 20-inch alloys coupled with larger ventilated disc brakes. A new body kit featuring wider side skirts and a bonnet with louvers gives the car a more purposeful stance even when standing still. There's a new front end with a shiny upper mesh grille and a black lower mesh grille. The XF-R also has a new rear spoiler and four round tailpipes. The "R" moniker placed on the four brake calipers as well as the rear end makes it clear where this car stands in the Jaguar hierarchy.

Interior comes with soft grain leather as standard, adjustable sports seats and a dark chequered aluminium trim on the dash. The "R" is also seen just above the glove box and at the bottom of the steering wheel. The XF-R will come with a choice of eight exterior colours including one called Salsa.

More of the Jaguar XF-R will be on display at the North American International Motor Show in Detroit.
