The famous British carmaker has unveiled its new, most fuel efficient engine to date in the form of a 2.2-liter diesel that develops in the region of 190 horsepower and is capable of returning 52.3 mpg (UK standard) on the combined cycle while emitting 149 g/km of CO2.
Jaguar has also revealed a couple of images showing a test mule version of the XF that has hit British roads sporting partial camouflage and the new oil-burner.
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. Advanced technologies making their way under the bonnet include a water-cooled turbocharger with low-friction pistons, new injectors and a new crankshaft.
The new engine configuration allowed Jag’ engineers to fit the new intelligent Stop-Start system, which is aimed at reducing the prolonged time spent in the shutdown and start-up phase usually experienced in such systems.
Before you judge Jaguar for jumping on the green bandwagon, let us tell you that the new car will deal with the spring to 62 mph (100 km/h) in 8.5 seconds and will have a top speed of 140 mph (225 km/h). The complete specifications and on-sale date of the 2.2-liter XF will be announced at the New York Auto Show, so stay tuned for more info.
