Jaguar’s new 225 mph XFR and XKR

Jaguar unveiled all-new supercharged 510bhp XFR and XKR at NAIAS today, and announced that the new XFR prototype has already run a top speed of 225.675mph (363.188km/h). The new XFR is the first XF to carry the ‘R’ designation which defines Jaguar’s most performance-focused models. Powered by a new supercharged 5.0-litre V8 engine developing 510PS and 625Nm of torque. But for the production car’s electronically limited 155mph top speed, it would be the fastest Jaguar ever, even faster than the 217.1mph (349.4 km/h) set by the XJ220 in 1992. The Jaguar XJ220 held the record for the highest top speed of a production car until the arrival of the McLaren F1 in 1994. High-speed runs play a large role in the history of the Jaguar marque, with this May seeing the 60th anniversary of the Jaguar XK120's record-breaking 132.6mph run set in 1949. Full details of the new models inside.

Mike O'Driscoll, Managing Director of Jaguar Cars said: "We've started 2009 with the introduction of advanced new generation petrol and diesel engines that set new benchmarks in terms of performance, economy and efficiency, including a new diesel for the XF that offers a marked improvement in CO2 and fuel economy. Our cars meet the challenges of the modern world and the needs of today's consumers – and they're also true to the Jaguar philosophy of creating beautiful fast cars."

The XF has already secured 'Car of the Year' awards from two major UK automotive magazines and more than 30 other commendations worldwide, so the new XFR, a new high performance diesel and a host of changes for the 2010 Model Year, including the launch of the new luxurious 'Portfolio' model, will make the XF an even more attractive proposition.

Featuring all-new AJ-V8 Gen III petrol engines and new AJ-V6D Gen III diesel engines, the XF now delivers more power and more performance with comparable or better fuel economy and emissions than the engines they supersede.

The XFR is powered by the all-new supercharged 510PS (510bhp SAE) V8 with acceleration from 0-60mph in just 4.7 seconds making it the ultimate Jaguar sport saloon. A naturally aspirated 5.0-litre V8, producing 385PS, powers other V8 XF models.

Distinguished by unique exterior and interior design features, the XFR includes revised bumpers and lower front air intakes, sill extensions, bonnet louvres and grilles, four tailpipes, a boot-lid spoiler, unique seats and 20-inch alloy wheels. The new XF 3.0-litre AJ-V6D Gen III diesel features a twin sequential turbocharged engine available as the 275PS/600Nm S or a 240PS/500Nm version. Both offer exceptional efficiency and refinement and in the case of the Diesel S accelerates from 0-60 in just 5.9 seconds.

With 275PS, the new XF 3.0-litre diesel S is 33 percent more powerful than the acclaimed 2.7-litre TDV6 it replaces. Torque peaks at a substantial 600Nm, with 61 percent more torque available from 1500rpm.

Every new engine for the XF range has highly competitive fuel economy and CO2 emissions figures. Both diesel versions deliver combined average fuel consumption of 42.0mpg – an improvement on the acclaimed 2.7-litre engine of nearly 12 percent – and a CO2 of 179g/km.

In the UK, pricing of the new XF range starts at UKP32,900 for the 3.0-litre petrol. The 3.0-litre diesel model is available from UKP33,900 while the new 3.0-litre Diesel S starts at UKP36,900. The XFR is priced at UKP59,900. These models are available from late March.
