2012 Jaguar XF shows off newish nose, 2.2-liter turbo diesel engine

Jaguar's announced that the soon-to-be-revealed 2012 Jaguar XF will be fitted with a new 2.2-liter turbo diesel. Great, a powertrain we won't get when it shows off this newish nose at next month's New York Auto Show.

The new diesel develops approximately 190 HP (190 PS) and 332 lb-ft of torque, and is capable of returning 52.3 mpg on the combined cycle while emitting 149 g/km of CO2. We have no idea what that means on the 'merican cycle.

And here it is, making its debut on UK roads fitted to a prototype face-lifted Jaguar XF, the new four-cylinder 16-valve common rail diesel engine displaces 2,179 cc and is installed in a north-south configuration for the first time. The new engine features a water-cooled turbocharger with low-friction pistons, new injectors and a new crankshaft.

This new configuration allowed Jaguar engineers to add a new oil pan and new electronic systems affecting the crankshaft to allow the new intelligent Stop-Start system to operate more efficiently.

Mated to a new eight-speed ZF automatic gearbox, the 190HP diesel can push the facelifted XF to 62 mph (100km/h) in 8.5 seconds before achieving a maximum speed of 140 mph (225 km/h).

Cool. Too bad none of that is relevant to us here in the colonies. Damn Brits, always keeping the turbo-diesels for themselves.
