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.
