The XF has received a facelift from Jaguar and presented a fresh model with a diesel engine, the Jaguar XF S, which makes the saloon provide 24 mpg. The new engine of the Jaguar XF is an enhancement of the 2.7-liter AJ V6 that was mutually engineered with PSA and is also the power behind the Land Rover Discovery.
Enhanced capacity has reached 3.0-liter, and potency is boosted by about 33 per cent, from the original 207 hp to the new 272 hp. Increases in torque has reached 420 lb.ft from the original 320lb ft, a 66 percent boost.
This torque figure is higher than all of its rival except from the Bmw 535d. With the new engine the Jaguar XF S, which will be available to dealers by March, can accelerate from standstill to 60 mph in 5.9 seconds, 1.8 seconds quicker than the old 2.7-liter diesel engine. The vehicle's CO2 emissions have significantly decreased from 199 g/km to 179g/km.
The engineers of Jaguar have uprated the powerplant's forced induction system. Reaching 2800 rpm, the bigger of the two turbos does all the labor, at which point the smaller unit begins to operate.
It is claimed by Jaguar that this system enhanced efficiency and decreases fuel utilization. Together with the 272 hp powerplant, there will also be a 237 hp variant with identical fuel usage and CO2 discharge, however, that model's acceleration time from 0-60 mph is increased to 6.7 seconds. The latest diesel Jaguar XF S receives 20-inch rims and a boot lid lip spoiler to make it distinct from other XFs
A Portfolio model is going to be added by Jaguar to the XF lineup, which will get identical treatment to the XK and XF Portfolios; anticipate bespoke interior trim and colors, as well as lots of leather, and exterior touches such as shiny aluminum wing vents.
Its petrol V8s will be uprated by Jaguar in 2009, starting with a new 5.0-liter powerplant that's scheduled to be revealed in the XFR super-saloon at the Detroit Auto Show next month. This powerplant, which comes with a supercharger, will provide 503 hp.
