Jaguar XFR speed record
The video behind the quest to reach 225mph in a Jaguar
Two new five litre direct injection V8 engines have been added to the 2010 model Jaguar XF range for the NZ market. These engines in the 5.0V8 and XFR models produce more performance with the same economy and two percent less emissions than the 4.2 litre V8 they replace.
The 5.0V8 model produces 283 kWs and 515 Nm of torque, while the supercharged XFR has 375 kWs and 625 Nm. They will sell for $159,990 and $209,990 respectively.
The new XFR is the first XF to carry the R badge, which defines Jaguar’s most performance focused cars. The XFR has had a 23 percent power hike, while torque is up 12 percent and with a 0-100 km/h acceleration time of 4.9 seconds. The naturally aspirated 5.0V8 has gained 29 percent more power and 25 percent more torque. Both V8s meet Euro5 emission regulations which are not mandatory until 2011.
The XFR has a sixth generation twin vortex supercharger, while the central spray direct fuel injection increases efficiency and torque. Variable camshaft timing improves throttle response and efficiency and a variable geometry inlet manifold on the naturally aspirated engine increases low and high end torque.
The new XFR has the active differential control and adaptive dynamics suspension previously only available in the top models of the XK and XJ range. The active differential is electronically controlled to vary its locking torque to each wheel depending on surface conditions and the amount of power applied to optimise traction. The adaptive dynamics suspension automatically adjusts the damper settings to suit road conditions and the way the car is driven, optimising the balance between ride comfort and handling and road holding. Both V8s have variable ratio speed sensitive power steering.
The six speed automatic has been given additional clutch plates and an uprated torque converter to handle the XFR’s added zest. The 2010 XFR is distinguished by 20 inch alloy wheels, revised bumpers and lower front air intakes, sill extensions, bonnet louvres and grille, four tailpipes and a boot lid spoiler.
The XFR’s front brakes at 380 mm diameter are the largest ever fitted to a Jaguar and come with ABS, EBD, EBA and cornering brake control.
Inside there are more unique details with soft grain leather and a dark oak veneer in the wood trimmed areas to complement the XFR specific dark aluminium mesh finish. Fourteen way adjustable sports seats include adjustable squab bolsters.
There is a keyless entry with the smart key system, automatic climate control, trip computer and split folding rear seats. The V8 has a 320 watts, eight speaker sound system, while the XFR comes with a 440 watts Bowers & Wilkins 13 speaker system.
The same new five litre V8 engine options are also fitted to the 2010 XK and XKR coupe and convertible models.
The XK has similar comprehensive specification and equipment to the V8 engined XFs. The XK pricing starts from $229,990 for the V8 Coupe, with the flagship XKR convertible tagged at $274,990.
The XFR and all the XK models will only be available to customer factory forward order. The XF 5.0 V8 and other XF models will be available as Jaguar dealer stock items.

Wing Commander Andy Green OBE – the fastest man on earth and the World Land Speed Record Holder — drove up Goodwood’s famous hill on the weekend in Jaguar’s fastest car ever, the XFR Prototype* that recorded 225.675mph (363 kph) on the Bonneville Salt Flats towards the end of last year.
Andy Green was the first person to break the sound barrier on land when he recorded 763.035mph (1,228 kph) in the Thrust SSC in 1997. He said: “It is always a thrill to drive at the Festival of Speed and all the more so in a ‘proper’ race car. I hugely enjoyed the Bonneville Jaguar, and the crowd loved it too — this is the sort of car that they come to watch. Now I want to go and drive it at Bonneville!”
Rocketsports Racing owner, Paul Gentilozzi, was behind the wheel when the car made its record-breaking run in Utah, so it was fitting when he attended Goodwood over the weekend to drive the car up the hill in the First Glance run throughout Friday and Saturday.
Paul Gentilozzi said: “During my career, I’ve raced worldwide from the southern tip of New Zealand to Le Mans. Along the way, I have been privileged to drive and own so many exciting cars but I’ve never driven one that was as exciting to drive fast as this Jaguar.”
Jaguar also showcased a unique XKR in the supercar run at Goodwood, driven by Mike Cross, Jaguar’s Chief Engineer of Vehicle Integrity. Developed to explore the harder side of the XKR’s character and unfettered by the requirements of a road car, the engine torque and power were both significantly increased to continue the Jaguar tradition of special cars for Goodwood.
The standard XKR features a new 5.0-litre V8 supercharged engine which has significantly enhanced the sporting character of the car. This special Goodwood XKR’s engine torque was increased from 625Nm to 700Nm and with power up from 503hp to 522hp, it will accelerate from 0-100kph in around 4.2 seconds.
Fitted with 21-inch wheels and a lowered ride-height, the XKR had an ‘interesting’ one-off lime green paint scheme with satin graphite detailing to the front grilles, headlights, door mirrors, side window surrounds, rear signature blade and bonnet louvers. The car also featured a unique graphic on the side and bonnet of the car proudly stating that it is an XKR.
*Running with minor aerodynamic and safety modifications to meet the requirements for a Bonneville run, the 225mph top speed was achieved with additional horsepower liberated by a remapped ECU, a modified air intake and exhaust system and revised supercharger settings. No internal engine components were changed and the six-speed automatic transmission was standard, including the gear ratios.
The new Jaguar XFR has just been shown off for the first time at the Detroit Auto Show and it has some serious claws. Set to go head-to-head with the big dogs in the high-performance luxury sedan segment, the XFR draws its power from a new version of Jaguar’s AJV8 that’s larger at 5.0 litres of displacement and supercharged to produce 510 bhp and 460 lb-ft of torque. This will take the new Jag from 0-100 kph in just 4.7 seconds and to an electronically limited top speed of 250 kph. The XFR is also fitted with new 20-inch Nevis alloy wheels and larger brakes with calipers bearing the “R” logo.
The XFR features a number of exterior tweaks over the standard XF that emphasise its sporting nature, including a new front end with a new bumper design incorporating large, chrome trimmed air inlets on either side, hood vents, new fenders, side sills, a decklid spoiler, and a new rear bumper that houses four exhaust pipes.
The interior is also dressed up with new dark aluminum trim, sports seats bearing the “R” logo and a sport steering wheel. The new range-topping XF can be had in eight colors: Botanical Green, Indigo, Kyanite Blue, Liquid Silver, Lunar Grey, Porcelain and Salsa.
