By Harvey Schwartz Challenging the rules and standing out from the crowd, the new 2010 Jaguar XFR fuses sports car styling and high-performance with the refinement and sophistication of a luxury sedan. It is a defining example of Jaguar’s dedication to creating beautiful fast cars-and with a magnificent new engine, that are quite simply the best ever setting new standards across the board. When it was introduced last year, the all-new XFR was recognized as a dramatic expression of a bold new Jaguar design language. It also soon became apparent that here was a car where the driving experience exceeded the expectations created by the striking exterior styling. The new XFR takes this driving experience to new levels, shifting the balance even further towards dynamic super high performance while still retaining the XF’s core values as a refined and luxurious sports sedan. Power comes from an all-new 5.0 liter DOHC direct-injected V8 with an integrated roots-type twin vortex supercharger utilizing twin-intercoolers that generates 510 horsepower and 461 pound-feet of torque. Immediately recognizable thanks to unique 20x9-inch Nevis alloy wheels with Jaguar Supercharged engraving and wrapped with Dunlop’s finest ultra-high-performance tires, a new front end design with a centered mesh grille with the Jaguar’s growling signature head, beautifully formed lamp clusters with Bi-Xenon adaptive headlamps, revised lower chrome air intake, side intakes to cool down the giant internally ventilated discs clamped with six-piston calipers, two working hood louvers, front fender heat extractors, four polished tailpipes, an aerodynamically functional rear spoiler, coupe-like profile with a slingshot C-pillar surrounded by a thick chrome strip, and deeper side sills, the new 2010 XFR is also the first XF to carry ‘R’ badging.
It was love at first sight when I picked up this liquid silver painted, long, low and sexy coupe-like sedan. It quickened my heartbeat when I pushed the red pulsing start button and fired up the all-new supercharged 5.0-liter V8 engine. Compared to last year’s XFR with a supercharged 4.2-liter V8, power has increased by a remarkable 23 percent and torque has increased by 12 percent. This new mighty engine gives the XFR a 0-60 mph time of only 4.7 seconds. More relevant in everyday driving, an excellent indicator of the XFR’s great flexibility is the time it takes to accelerate from 50-70 mph, just 1.9 seconds. Sound quality is a key characteristic of all Jaguars and is one particular aspect that customers relish. The new XFR has received special attention to deliver the required V8 intake sound character commonly absent on supercharged engines. Intake manifold pressure pulsations are fed into an acoustic filter at the rear of the engine that is tuned to ‘tenor C’, with the output from the filter ducted into the cabin. The filter is controlled by the engine management system which allows the acoustics to enter the cabin only under certain conditions, such as when the engine is accelerating hard, thus maintaining the desired sound quality at all times. It is music to any performance enthusiast’s ears. Mated to the more powerful supercharged engine is an enhanced version of Jaguar’s acclaimed ZF 6HP28 electronically controlled, six-speed automatic transmission. Additional clutch plates and an upgraded torque converter are incorporated into the XFR model to facilitate the extra power. You can keep the transmission in Drive for everyday driving with extremely smooth gear changes and optimizes performance and economy at all times, or you can shift it into Sport that changes the engine mapping, stiffens the suspension and changes the ratio of the power steering for quicker response. For even more thrills, you can also shift the XFR sequentially with either of the steering-wheel mounted paddle shifts to quickly shift up or down the six forward gears for sharper acceleration and de-acceleration. This is pure sports car fun at your fingertips.
Enhancing the enjoyment and thrilling ride offered by the new XFR are fully independent suspension, control arms, coil springs, gas-charged shocks and a sway bar up front with a multi-link rear that features coil springs, gas-charged shocks and a sway bar. The new changes to the XFR’s chassis dynamics come from two new advanced technologies, Adaptive Dynamics and Active Differential Control, which gives a more comfortable, and controlled ride when needed or by turning off the system you can let the rear slide when slicing through steep curving roads. Active Differential Control (ADC) with traction-only functionality and handling functionality is an electronically controlled alternative to the traditional, wholly mechanical differential, offering more subtle control strategies. ADC can vary its locking torque (and therefore the proportion of torque to each driven wheel) depending on surface conditions and power applied. Its control strategies optimize traction at each wheel, improving acceleration on low-grip surfaces while also enhancing cornering ability. ADC has no adverse effect on either refinement or stability-where the traditional, mechanical differential can compromise stability under hard applications of power, demanding more corrective input from the driver. Whereas a mechanical differential is permanently active, the XFR’s new ADC system is switched off when not required, so unlike the mechanical alternative, it does not risk undesirable understeer, and creates no issues with noise, vibration or harshness (NVH) at low speeds. The differential is operated by an internal electric motor and ‘ball-and-ramp’ mechanism, and contains a multi-plate clutch, which transmits or ‘vectors’ torque to the wheel with the most grip. The multi-plate clutch assembly is designed to prevent excessive differential slip, but differs fundamentally from a conventional traction control which uses the brakes to counteract slip after it has occurred.
Adaptive Dynamics (AD) is a sophisticated active damping system which automatically adjusts suspension damper settings to suit both road conditions and the way in which the car is being driven. By removing the need for compromise between a fixed, softer setting for ride comfort and a fixed, firmer setting for tauter body control and handling, AD allows the balance between rides and handling to be optimized whatever the circumstances. Unlike earlier systems with only a small number of steps in the damper settings, it offers a progressively variable damping strategy between wide extremes, to deliver a comfortable but sporty ride with impressively sharp handling responses to your inputs. The three primary functions of AD are to control vertical movement, roll rate and pitch rate of the body. It does this by analyzing induced body motions one hundred times a second, and setting each damper to an appropriate level in order to maintain a constant and level body attitude, thereby optimizing control without compromising ride. Also one hundred times a second, it predicts the roll-rate due to steering inputs, and selectively increases damping forces to reduce that roll rate-improving handling feel and driver confidence-as well as analyzing fore and aft pitch rates due to throttle and braking inputs, and again varies damping forces to reduce pitch, further improving comfort and control. Additionally, AD improves ride by monitoring wheel position five hundred times a second and automatically increases damping rate as the suspension approaches the limits of its travel. Similarly, it controls wheel ‘hop’ by varying damping to move any wheel out of a natural bouncing frequency, again benefitting ride comfort, handling and even grip.
The new XFR also features Handling functionality, which is unique in this class. In conjunction with the DSC Off option and JaguarDrive Control with Dynamic Mode, this supplements all the advantages of Traction Only Functionality with a number of more driver-focused dynamic characteristics. Dynamic Mode modifies the throttle, stability and transmission parameters, and also modifies the AD responses. The combination of ADC and Dynamic mode with DSX Off allows controllable power-on oversteer, and improves off-throttle stability, allowing quicker, more spirited cornering when you want to take the new XFR to its limits of adhesion. It can also improve stability in situations such as an emergency lane-change maneuver at high speed and, in combination with DSC, reduce the brake interventions which the more enthusiastic driver might see as intrusive. So working with DSC, the TCS traction control system and ABS braking function, ADC can significantly improve overall vehicle performance, and provide even more precise driving feel. It is amazing how quickly the XFR reacts to my inputs at the wheel and at the throttle when the systems are turned on or off. It is the perfect combination of electronic intervention when wanted and when no wanted to take the XFR to its limits with no electronic intervention. The perfect Jaguar! Improving handling and response even more is the new fast ratio steering rack. Additional benefits come from improvement to the front-to-rear aerodynamic balance resulting from the new rear spoiler and deep front bumper. The wider stance, lower chassis height and its low overall aerodynamic drag coefficient of only 0.29 contributes to both low wind noise and inherent high-speed stability. Contributing even more is the already stiff body shell, the stiffest in its class, is a new rear subframe, a trunk cross-brace and a front cross brace. Quickly and safely slowing the new XFR down from speed are massive 14.9-inch front and 13.6-inch internally ventilated power brakes. The front discs are clamped with six-piston calipers while the rear features four-piston calipers. Enhancing braking power and control are standard ABS, Brake Assist and Electronic Brake Force Distribution. The pedal feel is very linear, a solid feel all the way from high speed to stop. These brakes completed the circle of super-high-performance acceleration and handling prowess. The interior cabin truly matches the sportiness, comfort, and luxury under the skin of the new XFR. It is both modern, individual and uniquely Jaguar and hints at the car’s super-performance. It features a full soft grain leather interior standard including suede on the pillars and headliner. An electric sunroof to let in more air and sunlight when desired, and a new Dark Oak veneer set on the dashboard and door trim. Its new 18x14-way, heated/cooled front adjustable sports seats have newly shaped electrically adjustable squab bolsters for significantly improved lateral support at higher cornering speeds. Each XFR seat, front and rear, has the ‘R’ logo embroidered on it squab and the front seats have leather seat-back map pockets. The leather-trimmed, heated, power tilting/telescoping, three-spoke steering wheel feels perfect in your hand and is the right size for quick inputs. It also features its own ‘R’ logo at the bottom. The dashboard introduces a unique, dark mesh aluminum finish, and another discreet ‘R’ badge on the passenger side of the instrument panel. The easy to see instrument cluster’s speedometer and tachometer have the unique sporting signature of red dial pointers and carry the ‘supercharged’ motif. At startup, the ‘R’ logo appears on the Touch-screen as part of the XFR’s ‘driver handshake’ sequence.
The XFR is packed with user-friendly technologies such as full shift-by-wire transmission controlled by the JaguarDrive Selector, plus adaptive cruise control with Automatic Speed Limiter plus a radar-based Blind Spot Monitor warning you when there is another vehicle nearby in a different lane, and a rear parking aid TV camera with a clear view of the area behind the car on the Touch Screen while in reverse. The Touch-screen is now upgraded with on-screen guidance lines that move according to steering wheel angle to indicate the area into which the car will reverse. The Jaguar navigation system now includes turn-by-turn instructions in the message center. An Acoustic Laminated Windscreen is also set in place to help lower outside noise levels. The XFR also comes with the incredible Bowers & Wilkins 440-watt system with Dolby ProLogic II surround sound and 14 speakers. The Portable Audio Interface allows simple, direct connection of iPod and MP3 players with full control via the Touch-screen or steering wheel-mounted controls. JaguarSense allows touch-sensitive operation for the glovebox release and interior lights-and those lights feature soft, Phosphor Blue interior mood lighting with Halo illumination around the key switch packs to ensure easy and positive night-time operation. Digital and SIRIUS satellite radio with HD is also standard. Other standard equipment not mentioned above includes all-express up/down windows, dual-zone climate control through the Touch-screen, electronic parking brake, variable-rate wipers/washers, center console with three cupholders, storage slots in each door, rear air vents to more directly channel cool or heated air to the rear seats including a pull-down armrest with dual cupholders, self-dimming rearview mirror, two-person memory seats/outside mirrors, new exterior mirror design offers aerodynamic improvements plus improved functionality with its LED side repeaters, Jaguar signature door scuff plates, thick cut-pile carpeting with front and rear floor mats including the Jaguar logo leaping cat embroidered up front, dual map lamps, grab handles above each door for easy entry/exit and dual, lighted vanity mirrors. To keep all safe in the event of a collision is standard safety features including front/rear crush zones, steel beams in each door, tire pressure monitoring system, anti-theft engine immobilizer, driver and front passenger front and side airbags, active head restraints, side curtain airbags for all outboard seats, three-point safety belts with front pretensioners/load limiters, latch restraint anchor system, and remote security system. The new 2010 Jaguar XFR is a tour d’ force in super-high-performance driving with elegant, luxury on the inside.
