Jaguar XF will benefit from a new 2.2 litre diesel with 190PS and 450Nm (332 lb-ft). The superbly efficient power unit returns 52.3 mpg on combined cycle and just 149 g/km of CO2.

The engine is four-cylinder 16-valve common rail diesel with 2 179 cc of displacement. It features a water-cooled turbocharger with low-friction pistons, new injectors and a new crankshaft. There are also a new oil pan and new electronic systems affecting the crankshaft to allow the new intelligent Stop-Start system to operate more efficiently.

i-Stop-Start will reduce the time spent in the shutdown and start-up phase. Along with it, there is an advanced 8-speed ZF automatic gearbox.

The acceleration is satisfying – 0 to 100 km/h in 8.5 seconds and a top speed of 225 km/h (140 mph).

Jaguar XF diesel will be announced at the New York Auto Show.
