Overview
The XF was launched at the 2007 Frankfurt Motor Show[3][4] following the public showing of the C-XF concept in January 2007 at the North American International Auto Show. Designed by Jaguar's design director Ian Callum,[5] it was a significant design change from its predecessor. The styling of the finalised production XF varies from that of the C-XF, most notably around the front lights and nose, which incorporates an oval mesh grille harking back to the original Jaguar XJ of 1968. The boot lid retained the S-Type's chromed blade to its edge, but also included a "leaper" Jaguar logo as well.
The interior included some unique features such as the air conditioning vents which are flush-fitting in the dash, rotating open once the engine is started, and a rotating gearshift dial called the JaguarDrive Selector which rises out of the centre console.[6] Another departure from the traditional Jaguar cabin ambiance is the use of pale-blue backlighting to the instruments, switchgear, and around major control panels. Some minor systems, such as the interior lighting, are controlled simply by touching the light covers. The glove compartment also opens to the touch. Unusually the XF has no cloth interior option, with even the entry level model being fully trimmed in leather - even areas that have employed plastic on previous Jaguars. Real wood veneers are available, but have been joined by aluminium, carbon fibre and piano black lacquer trims to create a modern look to the passenger compartment.
Customer deliveries commenced in March 2008[7] with a range of V6 and V8 engines.[8]
Facelift (2011-)
The facelift includes front and rear styling changes which are based on the original Jaguar C-XF concept car, internal trim enhancements, adaptive cruise control, and a new four-cylinder 187 bhp (139 kW; 190 PS) 450 N·m (332 lb·ft) 2.2-litre diesel engine, which is combined with a new eight-speed automatic transmission and stop-start technology to emit 149 g/km CO2 and fuel consumption of 52.3 mpg-imp (5.40 L/100 km; 43.5 mpg-US).[10]
XF Models
The XF was launched with a variety of models called, depending on country, 'SE', 'Luxury', 'Premium Luxury' (or 'Premium'), 'Portfolio' (or 'Premium Portfolio'), 'SV8' (or 'Supercharged') and 'R'. For the UK market, company car friendly 'Executive Edition' and 'SE Business' models with a lower tuned versions of the 3.0 L and 2.2 L diesel engines respectively are available.XF Supercharged (2009–)
The 2008 4.2 supercharged engined was replaced by the new 5.0-litre supercharged engine rated 470 PS (346 kW; 464 hp), and came with Adaptive Dynamics (computer controlled continuously variable damping) and Active Differential Control (electronically controlled rear differential).[11]XFR (2009–)
Police car (2009-)
A special version of the XF Diesel S was announced in 2009 for the UK police car market, with the first police force orders in 2010.[14] It included a roof-mounted light bar with 3,600 light elements, side alley lights, blue and white strobing LEDs in the grille and blue flashing LEDs along the side of the car, blue and red flashing LED lights in the rear light clusters.[15][16]XF Sportbrake (2012-)
At the end of 2011 a camouflaged XF estate was spotted and indicated that the Sportbrake was nearing its Autumn 2012 on-sale date.[17] In March 2012 the Jaguar Sportbrake was formally revealed along with some technical information. When the Sportbrake goes on sale it will be available with all of the saloon's engines and has a loading capacity of 550 litres with the seats up and 1,675 litres with them folded[18] - the maximum capacity surpasses that of the BMW 5-Series Touring, Cadillac CTS Sport Wagon[19] and Volvo V70. The extended roofline increases rear headroom by 48 mm and the rear bench includes a 60:40 split and remote-controlled 'one-touch' folding function. The load area is fitted with multi-function rails and is 1,970 mm long and 1,064 mm wide.[20]Specifications
Aerodynamics
The car body was developed using Computational Fluid Dynamics (CFD) before the car ever saw a wind tunnel. Every area from the outer skin to the lightweight, composite undertray to the cooling airflow (even the shape of the exterior mirrors) was optimised using this process. The higher, squarer tail is more efficient aerodynamically than a lower, rounded one, and the XF’s coupé-like roofline and raised bootlid lip improve airflow over the rear of the car. As a result, the XF has the best aerodynamic performance, in terms of drag, of any production Jaguar ever and is better than the race-bred, limited edition XJ220 supercar.The XF’s drag coefficient is 0.29, and the front-to-rear lift balance is precisely zero. This aerodynamic performance minimises wind noise, reduces fuel consumption, and aids strong high-speed stability and handling.[citation needed]
Chassis
The basic sub-structure of the XF has been carried over from the S-Type, although the body has been stretched to meet crash safety requirements, and heightened to provide additional headroom while still retaining the "saloon within a coupé" proportions. The suspension and mountings are the same as that used on the XK, while the engine line-up is basically similar to that used in the S-Type.Sound and vibration insulation is provided by the addition of a special underbody tray and engine mounts, a tuned exhaust system, and a double bulkhead between the engine bay and passenger compartment.

A new 5.0 L V8 AJ133 GEN III engine was launched in 2009, which replaced the 4.2 V8 in most markets. The North American market retained the 4.2 L V8 as an option until 2010, as the 3.0 V6 was not made available. The supercharged version of the new V8 engines was used in the new XFR sports model.
The 2.7 L V6 diesel engine, replaced in 2009 with a new 3.0 V6 diesel AJ-V6D Gen III,[22] came in two states of tune.[23] The diesel engines are a product of the joint venture between Ford and Peugeot-Citroën.[24]
Transmissions
The XF was launched with only an automatic gearbox. The ZF 6HP28 six-speed automatic with torque converter lock-up is programmed to shift 10% quicker than before and is fitted to all petrol engines. Diesel engines are fitted with an advanced eight-speed ZF automatic transmission. On both transmissions gears can either be selected using a rotary dial that rises from the centre console on start-up or can be manually controlled using paddles behind the steering wheel.Engine specifications
All XFs are automatic and are Euro 5 compliant. The petrol 3.0 V6 was discontinued in Europe in 2010, but continues to be sold elsewhere.Next Green Car an organisation that analyses vehicle emissions and rates them from 0 (cleanest) to 100 (dirtiest) - analysed the emissions from Jaguar's current XF range:[25] ADAC's EcoTest has also rated two of the diesel engines.

Equipment
Sound system
The XF's standard audio system comprises a 10 speaker, 400W set-up that includes a radio, CD player, WMA and MP3 compatibility as well as USB storage devices. The optional upgrade boosts power to 600W which is fed through 11 speakers (including sub-woofer) and comes with a DSP amplifier. A digital radio tuner is optional on all systems.[26]There is also an optional Bowers & Wilkins (B&W) surround sound system available. At its core there are 17 speakers which (with the exception of the aluminium high-frequency tweeters) employ B&W's Kevlar composite speaker cones. Each front door contains a 168 mm (6.6 in) woofer, a 100 mm (4 in) mid-range speaker and a 25 mm (1.0 in) dome tweeter (the latter two wired in parallel with a crossover), while each rear door houses a similar 168 mm (6.6 in) woofer and 25 mm (1.0 in) tweeter. As a centre speaker there is a 100 mm (4 in) full-range driver, similar to the two 100 mm (4 in) full-range 'surround' speakers located on the rear parcel shelf.
The B&W system has been reviewed by journalists at Autocar magazine, who proclaimed it the best in-car system they have ever heard.[27]
Multimedia interaction
A 7" full-colour screen is fitted to the dashboard of all XFs and can be used to control most multimedia systems. The same screen can also be upgraded with analogue and digital television capability. Available as an option is JaguarVoice™ which allows the driver to speak commands in order to control everything from the sound and navigation systems to telephone calls and the climate control system.[26]Safety
The XF was crash tested in 2010 by EuroNCAP and it gained a four star rating. The XF's result was seen as a disappointment by some car magazines.[28][29] When retested in 2011 the Jaguar turned in improved scores in adult occupant, child occupant and pedestrian areas.| Euro NCAP test results | ||

The Australasian New Car Assessment Program (ANCAP) also tested the XF and gave it a score of 32.38 points out of 37, fiving it an ANCAP rating of 4 out of 5.[31]
Thatcham's New Car Whiplash Ratings awarded the XF 'good' score for Geometric, Dynamic and Overall ratings.[32]
Security
Deadlocks, an alarm and an engine immobiliser are fitted as standard to the XF. The car also locks itself when it reaches a pre-set speed to help protect against carjackings.[33] The XF was tested by Thatcham's New Vehicle Security Ratings (NVSR) organisation and achieved the following ratings:[34]| NVSR | Rating |

Critical reception
James May of Top Gear during episode 10 of series 10 reviewed the XF. Among his remarks were: "[the XF] goes like a four-door XK" and that the XF was "better value for money" than the BMW 5-series.[citation needed]Jeremy Clarkson of Top Gear reviewed the XFR during episode 5 of series 13. During the review he said: "I'm not going to, even for a minute suggest that it's [XFR] better than the M5, but it's as-good-as. And praise does not get higher than that". During the same episode The Stig managed a lap time of 1:26.7 s with the XFR. Making the XFR only 0.5 s slower than its rival the BMW M5 (1:26.2).[35]
Jaguar speed record
On 7 November 2008, a modified XFR was driven by Paul Gentilozzi of Rocketsports, who prepared the car, to a new Jaguar record of 225.675 mph (363.189 km/h) on the Bonneville Salt Flats. The new record beat the previous Jaguar record of 217.1 mph (349.4 km/h) in a XJ220 in 1992.[36] Changes to the stock vehicle included low-mounted rear spoiler, increased power to 510 PS (375 kW; 503 hp) by a remapped ECU, a modified air intake and exhaust system and revised supercharger settings.[37] Although it should be noted that the unqualified 'Jaguar record' claim is somewhat dubious given that the XJR5 to XJR15 vehicles Jaguar campaigned in the late 1980's and early 1990's and the Jaguar Formula 1 vehicles of the 2000s would have in some trims been significantly faster.Awards
