Jaguar XFR

In the spring of 2009 reached the Jaguar XFR, sportier version of the XF range. It is distinguished mainly by its V8 engine of 5.0 liters and 510 horsepower. The Jaguar XF is a four-door sedan. For size and power, the XFR is an alternative version of the Audi RS6, the BMW M5 or the new Mercedes-Benz E63 AMG.

The XFR costs 98,900 euros, about 5,000 euros less than the BMW M5 (103,400 euros) and 20,000 euros less than the RS6 (121,550 euros). The Jaguar XFR reaches 100 km / h coming from standstill in 4.9 s, slightly higher than its rivals. The Audi RS6 does the 0-100 km / h in 4.5 seconds and 4.7 seconds BMW M5. The XFR's maximum speed is electronically limited to 250 km / h.

The average consumption is 12.5 Jaguar approved l/100 km. It is slightly smaller than Jaguar's supercharged V8 engine of 4.2 liters and 416 hp (12.6 l/100 km) which replaces the XF range, and far below those of its competitors. The Audi RS6 costs 13.9 l/100 km and the BMW M5 14.8 l/100 km (failure to know the consumption of the E63 AMG E-Class, 2009).

The new Jaguar XFR is distinguished from other versions of the XF by the chrome front air tickets, that are on the hood, the rear skirt in body color, four exhaust outlets, a spoiler on the trunk lid , new intermittent lateral smaller, LED, and the initials 'R' present in different areas of the body and interior. It is bringing some new alloy wheels and seven-spoke 20-inch double.

The brakes are larger, 380 mm to 355 mm in front of the XF V8 of 4.2 liters and 416 hp, which no longer marketed, and calipers are painted silver gray and bear the logo 'R'.

The XFR is available in eight body colors, six shared with the rest of the line XF ( "Ultimate Black", "Indigo," "Liquid Silver", "Lunar Gray", "Porcel Hain 'and' Botanical Green ') and two exclusive ( "Kyanite Blue" and "Salsa").

It also takes a few seats different from the other versions of the XF. In court sports, with more electric setting options are heated, ventilated and are lined with skin from one of the following colors: 'Warm Charcoal', 'Warm' Charcoal with Red Zone ',' Warm Charcoal with Tan and London Ivory.

All seats have saved the logo XFR 'R', present also on the steering wheel in leather finishing. XFR All surfaces are finished in dark oak wood. The dashboard has aluminum accents and includes the latest version of Jaguar's browser, which opens a new feature: the driver gets some of the instructions on two screens in the dashboard and in the navigation system itself.

The Jaguar XFR has all the systems driving aid that takes the XF, as obstacle detectors in "blind spot" BSM "that works with radar and the warning is displayed directly on the glass of the mirror (more information), the programmer active speed "ACC" (more information) and the speed limiter.

Motor

The XFR engine is a V8 5.0-liter, turbocharged and direct fuel injection. Da 510 hp and maximum torque of 625 Nm. Compared with the engine it replaces, the V8 4.2 liter, power increases from 416 to 510 horsepower and torque from 560 to 625 Nm.

Overfeeding is via a Roots-type volumetric compressor. It has some liquid-cooled intercoolers from its own cooling circuit. According to Jaguar, just hear the noise of the compressor. The maintenance of this new engine has to be done every 24,000 km or 12 months, whereas in the previous V8 was every 16,000 km or one year.

The XF 4.2-liter supercharged engine sound was spectacular. The XFR is an acoustic filter to the rear of the engine whose output is directed to the carrier for the driver to better perceive the sound of the V8. In this filter pressure pulses enter the air from the intake manifold under certain circumstances (the control unit is controlled by the engine).

The new V8 has variable valve timing 5.0 liters (62 º to 50 º on admission and exhaust). The compression ratio is 9.5 to 1. The block is made of high-pressure cast aluminum. The cylinder heads are also of this material, while the connecting rods are forged steel. This engine is 24 mm shorter in length than the 4.2 because it has changed the location of the oil pump.

As in the rest of the line XF, the XFR has automatic gearbox six relations (ZF), although the sportiest version has been enhanced with a more capable converter and additional clutch plates. The frame is more rigid XFR, an improvement that will share with all XF 2009.

The XFR is an active control of the differential ( "ADC"). Electrically operated, can vary the torque automatically lock. It consists of a multi-plate clutch and an electric motor which actuates it, thus changing the force that makes each wheel.

It also has a suspension that automatically adjusts the dampers to adjust the hardness to the track conditions and driving style ( "Adaptive Dynamic Suspension). This type of suspension eliminates the need of having to choose between two fixed settings, one soft (comfort) and a hard (more control over the car).

The main function of this device is to control the vertical movement and the rate of rolling and pitching. To perform these operations, the system can analyze a hundred times per second induced movement of the body and five hundred times per second the position of the wheels.

The "Adaptive Dynamic Suspension 'is of similar characteristics to the previous carrying the most powerful XF (4.2 of 416 hp), known as Computer Adaptive Technology Suspension" ( "CATS"). He had a button on the center console that allowed modify the response of the engine (which was made more directly to each movement of the accelerator) and gear (to be faster than the serial configuration) and adding a function more stability control called "Trac DSC". It allowed some extra slip out of the corners.
