2010 jaguar xfr

 The XFR receives a new, direct-injected 5.0L V-8 (also available for the 2010 XF). But the XFR's mill receives pressurization from a Roots-type, twin-intercooled supercharger. Despite a mighty output of 510 hp and 461 lb-ft of torque, the new engine comes sans weight or fuel mileage penalty -- its 15/23-mpg rating is the same as the outgoing supercharged 4.2L. Jaguar attributes this to a variety of new and altered components, including a direct-injection system, a variable-length intake manifold, and variable camshaft timing.
The new cam timing system relies on forces generated by the valves, rather than by oil pressure. The oil pump has been decreased in size and relocated as a result, reducing engine length by 0.94-in. These new technologies allow Jaguar to raise the compression of the engine to 9.5:1 (up from 9.1:1 on the 4.2L). Service intervals have been lengthened to 15,000 miles as well.
To transmit the engine's enthusiasm to the ground (and the driver), Jaguar employs two new electronically controlled systems in the XFR. The first, Active Differential Control, varies torque between the rear wheels depending on the surface. It attempts to prevent excessive wheel slip, but does not impede slippage with brake application. The press materials read: "The traditional, mechanical differential can compromise stability under hard applications of power, demanding more corrective input from the driver." Translation: This Jag allows easy power slides.
