Jaguar XF

Jaguar XF available with the naturally aspirated 5.0-liter V8, the Portfolio model includes ultimate craftsmanship details such as contrast stitching on leather trim, Jaguar Suedecloth Premium headlining, deep-pile carpet mats with contrast edging and embroidered logos, unique veneer and ventilated heated and cooled seats. But it is the new powertrain options that are at the heart of the changes for 2010 model year. The all-new 5.0-liter AJ-V8 Gen III engines - in 385bhp/380lb-ft of torque naturally aspirated and 510bhp/461lb-ft supercharged 'R' guise - add an entirely new, even more sporting dimension to the Jaguar XF range.

These new engines are Jaguar's most efficient ever, and they deliver power and performance at a higher level across the board. In the case of the supercharged engine, compared to the 4.2-liter V8, power has increased by a remarkable 23 percent and torque by 12 percent.

The result in the new Jaguar XFR is a 0-60mph sprint time of just 4.7 seconds(0-100kph in 4.9 seconds). More relevant in everyday driving, an excellent indicator of XFR's great flexibility is the time it takes to accelerate from 50-70mph - just 1.9 seconds.

The comparisons for the naturally aspirated engine are equally impressive. Power is increased by 29 percent and torque by 25 percent. The benchmark 0-60mph acceleration time is 5.5 seconds (0-100kph in 5.7 seconds) - some 0.8 seconds quicker than the 4.2 Jaguar XF. Better still, these improvements are achieved without hindering fuel economy and emissions performance. The new engines meet US ULEV II/Tier 2 Bin 5 emissions regulations.

And alongside these new engines, the naturally aspirated 4.2-liter V8 engine will continue to play a key role for the Jaguar XF and will be available starting January 2009. Customers will be able to order the latest naturally aspirated 5.0-liter V8 versions of the new Jaguar XF range from January 2009. The 510bhp supercharged V8 XFR will be available to order from February 2009.
