The2019 Jaguar XF Details

The Jaguar XF brings an unrivalled blend ofdesign, luxury, technology and refinement to lead the business car segment,underpinned by class-leading driving dynamics and refinement.

The dynamic, coupé-like design is formedaround Jaguar’s aluminium-intensive architecture and combines the outstandingproportions, elegant surfaces and perfect lines which define all Jaguar cars.The cabin is a seamless blend of contemporary luxury materials and finishes,traditional Jaguar craftsmanship and intuitive technology.

The XF uses Jaguar’s aluminium-intensivearchitecture to provide a unique combination of lightweight construction andoptimised driving dynamics. Double wishbone front suspension and Integral Linkrear suspension – combined with near 50:50 weight distribution – deliver theideal balance between ride and handling.

In rear-wheel drive form, the All-SurfaceProgress Control (ASPC), developed for low-speed driving in adverse conditions,automatically manages the brakes and the throttle to deliver the best possibletraction, enabling the car to pull away smoothly and without drama: the driveronly has to steer. ASPC is fitted to all automatic models and operates between3.6km/h and 30km/h, and the desired speed is set by the driver using the cruisecontrol switches.

The Touch Pro system, when enhanced withConnect Pro, customers benefit from InControl Apps, Remote, Navigation Pro and4G Wi-Fi hotspot through the vehicle’s advanced and intuitive 10-inch Touchscreen.

Audio systems include the exceptional 380WMeridian Surround Sound System.

Touch Pro features a high-performancequad-core processor and runs on state-of-the-art, ultra-fast Ethernet, anetwork technology that offers exceptional data transfer rates. Combined, theydeliver faster response times.

As part of this update, a new SmartphonePack which features Apple CarPlay for enhanced smartphone compatibility isstandard on all models. The technology mirrors the user’s smartphone allowingthem to access a selection of apps on the car’s 10-inch Touchscreen.

It looks like a grown-up XE

RANGESUMMARY

The XF will be available in Prestige andR-Sport in 250PS Ingenium 2.0-litre four-cylinder turbocharged petrol automaticRWD.

DESIGN

Staying true to the principles of elegantlines and disciplined surfacing, the Jaguar XF is one of the most visuallydynamic cars in the executive segment.

Integrity,simplicity: Perfect proportions, aerodynamic efficiency

“In creating the XF, as a design team wewere driven by discipline, the discipline of simplicity. Every exterior line onthe XF has a clear purpose – nothing is superfluous. Achieving that simplicitytakes time and requires great determination; it’s all too easy to add lines toa car, but much harder to add character by leaving lines out.

Inside too, we have been driven by thedesire to ensure the XF’s cabin is as comforting as it is comfortable.Innovative technology, including the 10-inch Touchscreen, is combined carefullywith materials that cosset and reassure.” – Ian Callum, Director of Design,Jaguar

From any angle the XF is instantlyrecognisable as a Jaguar. The sleek, coupé-like profile, long bonnet with deeppower bulge and the short front overhang mark this car out as a sporting saloonthat stands apart from the crowd.

Aerodynamic performance is optimised byapertures in the front bumper, which channel air over the front wheels. Thishelps to prevent the turbulent wheel wake from disturbing the smooth laminarairflow passing around the car.

The headlights are flush with thesurrounding panels, improving not only aesthetics but also aerodynamics. Theyalso feature Jaguar’s signature DRL.

The power bulge on the long aluminiumbonnet runs all the way through to the nose cone, emphasising the car’sperformance potential, integrating Jaguar’s latest-generation deployable bonnettechnology to the rear hinge assembly. Not only does this contribute to thesleek styling but also optimises visibility and pedestrian protection.

The one-piece aluminium bodyside pressingsemphasise Jaguar’s philosophy that surfacing should always be executed with thediscipline of simplicity and purity. Designing and manufacturing these panelsfrom a single sheet is extremely challenging but contributes not only to theoverall stiffness of the body, but also to surfacing purity and quality becausethere are no visible joints.

The elegant daylight opening graphicfeatures a full return, the form inspired by past Jaguar sports saloons. Withradii honed to within fractions of a millimetre to deliver the complexcurvature, the feature is testament to Jaguar’s expertise in working withaluminium.

Running from front to back, peaking abovethe rear wheel in terms of height and then tapering away, is a chamfered featureline known as ‘the spear of light.’ The reflections make the car appear evenmore lithe, more agile, and more elegant.

At the rear, the LED tail lights featurethe signature Jaguar graphic from F-TYPE – a line intersecting a roundel – alsoused on the XE. But here, the graphic is repeated, creating a clear hierarchyfrom XE, and an unmistakable pattern at night: everybody knows that this is theXF.

The chrome signature blade running acrossthe boot lid between the light clusters emphasises the XF’s taut surfaces anddynamic visual balance.

To deliver the flush fit of the lightclusters and perfect integration of the chrome blade, the boot lid is made fromtwo steel pressings joined by laser brazing. As well as being highlyenergy-efficient, this state-of-the-art process was selected for its precisionand neat, clean finish.

Interiordesign: simplicity, strength, space

The interior of the XF has always attractedpraise, especially the start-up sequence bringing the car to life as the rotarygear selector rises up from the centre console and the air vents rotate intoposition.

The brief was to retain that sense ofoccasion – and the strong, simple lines and horizontal feel of the instrumentpanel – but mature the design language and the use of materials, befitting theXF’s status now that XE is in position as the entry-level Jaguar sports saloon.

The layered instrument panel, with Jaguarsignature ‘Riva Hoop’ inspired by XJ, continues into the door, creating aunique cabin feel. This is enhanced by the generous application of veneers suchas Gloss Figured Ebony and textured aluminium trim such as Dark Hex.

Appreciation of the XF’s interior startsfrom outside – there’s an approach sequence leading you into the car as theJaguar Intaglio at the centre of the Riva Hoop is lit up.

Once in your seat, you notice how the doorsshut with reassuring precision and a sound painstakingly engineered to matchthe premium materials and perfect execution of the interior. Press the enginestart button and watch the backlighting fade: the effect is calming – this isyour personal space.

Look around and you notice the height ofthe waistline and the centre console: this enhances the feeling of being sat inthe seat rather than on it, creating a sense of safety, comfort and security.The strong horizontal theme of the instrument panel, the layering of it, andthe materials used for each layer creates a rich, luxurious, handcrafted feel.

Enhanced front seats provide even morecomfort for driver and front passenger as the upgraded ‘Luxury’ seats nowprovide powered ‘Z’ headrests with manually adjustable wings.

The XF’s 2,960mm wheelbase means that rearpassengers enjoy traditional Jaguar comfort while options such as the four-zoneclimate control system, heated seats and window blinds make the second row aneven more comfortable place to be.

ARCHITECTUREAND BODY STRUCTURE

The XF features a light, stiff bodystructure made predominantly from aluminium

Materialbenefit: aluminium-intensive construction

Aluminium alloys, self-piercing rivets, andstructural adhesives: these are the essential elements around which everyJaguar is designed. Used to create inherently light, stiff body structures,they enable the highest standards of performance, efficiency, safety anddynamics.

These attributes were engineered intoJaguar’s aluminium-intensive architecture from the very beginning. It is fromthis state-of-the-art modular structure that the XF was developed. Alsofeaturing advanced high-strength steels, the aluminium-intensive monocoque usesmaterials intelligently, exploiting each to its full potential.

Aluminium is also used to make the bonnetand front fenders, while the front-end carrier and cross- car beam are castfrom even lighter magnesium alloys.

The aluminium-intensive monocoque leveragesmore than a decade’s experience of manufacturing luxury cars from aluminium inhigh volume. The one-piece bodysides of the XF are testament to Jaguar’sworld-leading expertise in working with the material.

 Stamped from a single sheet of high-strength 6000-series alloy, thebodysides weigh less than 6kg and are among the most technically-challengingpanels Jaguar has developed and push the very limits of what is possible interms of designing and manufacturing in aluminium. Perfecting the deep haunchesand the sixth-light incorporated all of the learnings from F-TYPE in terms ofdepth of draw and tightness of radii.

Assembly to the rest of the structure usesa two-stage framing process. The technique allows for greater joint efficiencythrough optimised positioning of the rivets. This translates to increasedtorsional rigidity of the body.

Features such as the high-pressure die-castaluminium front suspension towers increase local stiffness and make asignificant contribution to the XF’s benchmark ride, handling and steering.

Quieterby design

The body of the XF is designed to behave asone homogeneous structure: wherever vibration energy finds a discontinuity itwill concentrate and then radiate noise through to the cabin. As a result,reducing structure-borne noise is an important way of delivering customaryJaguar refinement.

Every part of the body has been analysed toensure as many potential sources of noise have been designed-out. In someareas, such as the crash structure behind the front bulkhead, fully-sealed,double-wall structures are used. Where sound deadening has been applied, thelatest spray-on materials are used due to their combination of higherperformance and lower weight.

Foam baffles inside the aluminium sectionsalso contribute. These pieces are fitted during assembly: as the body passesthrough the e-coating ovens the heat causes the foam to expand so that itcompletely fills the section.

A further example of the painstakingattention to detail that delivers XF’s benchmark low levels of cabin noise istypified by the way in which the high-level brake light is fitted to the body.Running all the way along the full length of the rear screen, this full-LEDlight has a seal and an acoustic barrier behind to minimise any noise leakagethrough to the interior.

Closingthe loop: Recycled aluminium alloy

Aluminium pressings used where stiffness isa key criterion, such as under frame reinforcements, are typically formed from5000-series alloys. These include RC5754, a grade unique to Jaguar, which ismade predominantly from recycled material and also used on the XE sportssaloon.

Around half of this is scrap sourced fromthe press shops, helping not only the move towards closed- loop recycling butalso reductions in overall electricity consumption and therefore lifecycle CO2emissions. Innovations like this are a further example of Jaguar’s world-classaluminium expertise and drive for environmental sustainability.

Structuralintegrity: World-class safety

The XF has been engineered to meet the mostdemanding crash test requirements in the world, achieving the maximum five-starEuro NCAP rating. As part of the intelligent material mix in the body, the rearlongitudinal members and the B-pillar reinforcements are made from ultra-highstrength hot- formed boron steels, providing exceptional rigidity and stabilityof the occupant safety cell.

Pedestrian protection is provided by theenergy-absorbing properties of the front bumper and enhanced by Jaguar’slatest-generation deployable bonnet technology.

The system uses pressure sensors mounted inthe front bumper to detect collisions with pedestrians. When deployment isinitiated, pyrotechnic piston actuators integrated into the rear bonnet hingesfire, and, in 40 milliseconds, can lift the trailing edge of the bonnet byapproximately 130mm. This increases clearance between the pedestrian’s head andhard points in the engine compartment, helping to mitigate head injuries.

Jaguar’s commitment to improving pedestrianprotection in this way began back in 2006 with the launch of the XK.

CHASSIS

The Jaguar XF exceeds all expectations ofhow a business saloon should ride, handle and steer.

Dynamic,agile, composed

Whether on a mountain road or a motorwaycruise, from behind the wheel or relaxing in the back, the XF is designed todeliver a driving experience that sets the class standard.

The light yet exceptionally stiff body,with its combination of aluminium and advanced high-strength steels, deliversnear 50:50 weight distribution – the ideal starting point for dynamicsdevelopment.

Double-wishbone front and Integral Linkrear suspension systems provide the inherently high levels of stiffness neededfor agile handling and steering precision with the compliance essential forfirst- class comfort and refinement. Advanced damper technologies – bothpassive and continuously variable – improve ride quality still further andextend the XF’s breadth of dynamic capability.

“The XF has to deliver driver rewardthrough agility and immediacy of response when it’s called for, and yet greatride composure and comfort too. The XF’s light and rigid aluminium intensivearchitecture is a key enabler for us delivering those attributes, as itprovides an optimal basis for finely tuning the ride and handlingcharacteristics of the car. The result is that the XF is as satisfying to drivequickly, as it is comfortable to be driven in.” – Mike Cross, Chief Engineer ofVehicle Integrity, Jaguar

With components made entirely fromlightweight aluminium, the XF’s double-wishbone front suspension is modelledclosely on F-TYPE’s and was chosen because, fundamentally, there is no betterconfiguration.

Its exceptionally high camber stiffnessmeans the tyres are able to generate lateral force immediately – whichtranslates to sharper and more immediate turn-in. And the high roll camber gainmeans that the tyre’s contact patch is maintained, generating more grip anddelivering better feel.

Other refinements include lighter springsmade from narrower-gauge steel and low-friction, PTFE- lined bushes for thetubular anti-roll bar.

IntegralLink: Forces separated

The optimum balance of ride and handlingrequires lateral and longitudinal stiffness to be tuned independently. Thissimply isn’t possible with a conventional multi-link suspension rearsuspension: changes to one will affect the other, leading to compromises in thevehicle’s dynamics attributes.

Integral Link is different, enabling the XFto realise exceptional levels of comfort and handling. Bushes soft in recessionallow the wheels to move rearwards and upwards upon impact, providing excellentenergy absorption characteristics.

At the same time, camber stiffness can beincreased, delivering greater responsiveness. Greater caster stiffness can alsobe achieved, for greater stability under braking.

Electricpower-assisted steering

Steering response and on-centre feel areamong the most important attributes to define Jaguar’s dynamics DNA and this isevident with the XF.

Everything from the tyres through to thesteering wheel itself makes a difference but one of the key enablers is theenormous tuning potential of electric power-assisted steering (EPAS). Fromfilters that damp unwanted disturbances caused by road surface irregularitiesto algorithms that compensate for changes in ambient temperature – EPAS has farmore to offer than hydraulic systems ever could.

Incorporating all of the learnings fromF-TYPE and XE, the advantages of EPAS give the XF an even more connected feelwith intuitive, linear responses.

TorqueVectoring by Braking

Another technology proven first on F-TYPEand standard on the XF is Torque Vectoring by Braking. On corner entry, lightlybraking the inner wheels individually can mitigate understeer and help thedriver to take the ideal line. Intervention is subtle and virtually transparentto the driver, but the increased agility is felt immediately.

Next-generationdamper technology: smooth progress

Making the XF’s body lighter and stifferdelivers inherent benefits in terms of ride control, but Jaguar’s dynamicsengineers looked closely at other fundamental improvements that could be madewhen developing the XF. One of the most effective is the integration ofnext-generation passive damper technology to enhance comfort.

Passive dampers enable frequency-dependentdamping – the ability to vary damping force not only with the velocity at whichthe damper piston moves, but also as a function of its frequency. Inputs fromroad surface imperfections are high frequency inputs and large road undulationsare low frequency.

An extra valve in the piston provides anadditional bypass. Over road surface imperfections this extra valve opens,allowing some fluid to flow through it instead of the main valve in the piston.This reduces the damping force and makes the ride smoother and the drivingexperience even more relaxing. On smooth road surfaces the valve is closed,forcing all of the fluid to pass through the piston: damping force increases andthe ride becomes more controlled.

POWERTRAIN.Responsive, refined, rewarding

The XF’s four-cylinder Ingenium petrolengines are engineered for exceptional response, smoothness and refinement, andall benefit from stop-start systems and smart regenerative charging.Characterised by a rapid build-up of torque from low speeds to give effortlessacceleration, the linear throttle response and refined soundtrack makes thedriving experience as intuitive as it is rewarding. The XF offers a trulyremarkable breadth of performance and capability.

Designed, developed and manufacturedin-house to meet Jaguar’s exacting requirements for power, torque andrefinement, Ingenium is a modular family, which will deliver a wide range ofworld-class diesel and petrol engines.

The XF is available 2.0-litre four-cylinderpetrol rated at 250PS/380Nm. Every measure has been taken to ensure theseengines are as clean as they are quiet and smooth-running.

Features such as the offset cylinder boresand roller bearings for the camshafts and balancer shafts contribute toIngenium’s benchmark low levels of internal friction.

The split-cooling system features a mappedthermostat, a variable-flow pump and crossflow channels in the cylinder head toensure a rapid warm-up from cold. A variable flow oil pump and switchablepiston cooling jets cut parasitic losses still further and therefore reducefuel consumption and emissions.

Ingenium is also one of the first dieselengines to feature variable valve timing. A cam phaser on the exhaust sideallows the catalysts to reach operating temperature even more quickly, furtherreducing emissions. The technology also enables more efficient and robustregeneration of the particulate filter.

Complementing the inherently low levels ofvibration ensured by the design of the stiff, deep-skirt cylinder block areacoustic covers fitted to the cylinder head, the chain drive and the sump.These covers prevent radiated noise from the engine from reaching the cabin andcontribute to the XF’s exceptional levels of refinement. Switchable enginemounts provide extremely effective isolation from the body, further reducingthe transmission of structure-borne noise.

All petrol engines are now equipped with particulatefilters to make them even cleaner.** The highly efficient, close-coupledfilters are neatly integrated into the aftertreatment system and trap ultrafineparticles as the exhaust gas passes through them. Under normal drivingconditions, the trapped particles will be oxidised into CO2 and the filterregenerated whenever the driver lifts off the accelerator.

Four-cylinderpetrol power: Responsive and refined

The 2.0-litre four-cylinder Ingenium petrolengines have been developed entirely in-house.

All Ingenium engines deliver benchmark lowlevels of friction to optimise efficiency and refinement while the new petrolunits deploy twin scroll turbos to reduce lag and optimise power output.

Continuously Variable Valve Lift technologyimproves air delivery to the engine.

The powerplant features electrohydraulicvalve control to deliver unrivalled flexibility. This patented technologyprovides fully variable control of the intake valve lift for optimumefficiency, power and torque across the rev range.

In addition, cleaner combustion is ensuredby a new 200bar direct injection system, which features centrally mountedinjectors with optimised spray patterns to improve efficiency and reduceemissions.

In a first for Jaguar, the exhaust manifoldis also integrated with the cylinder head casting. Passing coolant through themanifold considerably reduces warm-up times, when engines are at their leastefficient, to enhance fuel consumption and control emissions.

Comfortablyahead: smooth 8-speed automatic transmissions

Every engine in the XF is available with aspecifically optimised version of ZF’s peerless eight-speed automatic. Combinedwith Jaguar’s unique rotary gearshift controller and paddle shifts, thesestate- of-the-art transmissions offer an unparalleled driving experience,blending exceptionally smooth launch behaviour with seamless shifting andefficiency.

The transmission controller monitorsdriving styles and adapts its shift patterns to suit. The ECU is also networkedto the Jaguar Drive Control, offering even quicker shifts and more dynamickickdown in Dynamic mode, and earlier up-shifts in Eco mode.

Complementing the stop-start system isTransmission Idle Control: if the vehicle is stationary and held against thebrakes with the engine running, one of the brakes inside the transmissionopens, reducing drag losses and therefore further reducing fuel consumption.

To improve driving comfort even furtherwhen running at very low engine speeds, all applications feature a pendulumdamper in the torque converter. This additional element is able to absorb verylow frequency vibrations and prevent them from passing through to the cabin.

INCONTROLINFOTAINMENT AND CONNECTIVITY

Touch Pro: World-class infotainmenttechnology

At the heart of Touch Pro is a 10-inchcapacitive Touchscreen. Like a smartphone, the home screen can be customised:widgets can be added to provide shortcuts to favourite features. It’s evenpossible to add extra home screens. And the Touchscreen accepts the ‘pinch tozoom’ gestures familiar to all smartphone users – nothing could be moreintuitive to use.

The optional enhanced 10-inch Touch ProDual View enables the central screen to display vehicle information, such assatellite navigation for the driver while the front seat passenger is able toaccess radio, USB or TV outputs simultaneously using the same screen.

XF Navigation Pro benefits fromdead-reckoning functionality, which interprets vehicle data up to 40 times asecond, and can accurately, position the vehicle even when GPS signals can nolonger be received – perfect for city centres.

When combined with Connect Pro, NavigationPro utilises a data connection to enable greater functionality andlocation-based features and information. This includes the Live Trafficfunction which alerts the driver to traffic jams on their route in order tomake their journey more seamless. The XF also offers door-to-door routeplanning and guidance incorporating public transport options, Commute Modewhich learns your daily drive so that it can automatically offer alternativeroutes to avoid congestion using historical and real-time traffic information,and Arrival Mode which shows a 360° interactive view of your destination whenyou’re 200m away – it will even advise on the nearest available car parkingspaces.

If you just want to enjoy the music,functions such as ‘Play more like this’ make it even simpler to access all ofyour favourite tracks. To make the most of it all there’s the option of a17-speaker, 825W Surround Sound System developed with renowned British audioexperts Meridian. The system benefits from Meridian’s Trifield and Audyssey’sMultEQ XT technologies to ensure optimum sound reproduction with benchmark lowlevels of distortion.

The modules that make up Touch Pro areconnected using Ethernet, and Jaguar is one of the very first vehiclemanufacturers to integrate this network technology into its electronicarchitectures. With a bandwidth of up to 1Gbit/ second, Ethernet can cope withhigh volumes of data, enabling very high infotainment system performance.

Together with a powerful quad-coreprocessor and Ethernet allows Touch Pro to deliver smooth graphics and fastresponse times. These technologies also ensure that the system’s capability canbe enhanced even further in the future.

Alwayson: The connected XF

Dialling-in to a conference call, booking ahotel room or just catching up with the news – with InControl Apps the XFensures drivers can seamlessly connect Apple and Android smartphones to thecar. Via a USB cable and the dedicated port in the centre console, InControlApps provides access to the compatible apps on the device using the vehicle’sTouchscreen.

Remote Essentials functionality, standardon all models, is accessed through the Remote app and enables customers to interactwith the XF from anywhere using a smartphone. It can display how much fuel isin the tank, whether the doors are locked and if the windows were left open.

For the last word in comfort andconvenience, on most models equipped with automatic transmissions, RemotePremium enables the driver to bring the cabin to a pre-set temperature byremotely starting the engine. A press of a smartphone button is all it takesfor the XF’s highly effective climate control system to heat or cool theinterior to the desired temperature before the journey even begins – perfectfor hot summer days or freezing winter mornings.

Using a SIM card and the vehicle antennafor the strongest and most reliable signal, the XF goes online and can functionas a Wi-Fi hotspot, providing a 4G connection for up to eight devices.

Online Media allows for the aggregation ofnumerous content providers and their personalised content – such as Deezer andSpotify – that gives access to more than 40 million music tracks and fourmillion on-demand programmes and podcasts. For the first time, these can bedirectly streamed from the vehicle without the need for a smartphone –providing a seamless and integrated experience.

Should car be involved in a collisionsevere enough to trigger the airbags, Protect will automatically notify theemergency services and provide the GPS location of the vehicle. Occupants canalso trigger an emergency call manually by pressing a button.

All-roundconvenience: Hands-free Gesture Boot Lid

Powered Gesture Boot Lid delivers greaterdriver convenience with a hands-free solution to access the bootspace even whenthe owner has their hands full. The system is available with keyless entry andparking aid and allows the owner to open and close the tailgate by simplywaving their foot underneath the rear bumper of the vehicle.

Sensors beneath the rear valance are ableto detect any movement as the customer swipes their foot underneath. Thistriggers the boot lid opening, making it possible to load any items into theloadspace without having to put them down.

DRIVERASSISTANCE

From traction systems which know the typeof surface you’re driving on to a stereo camera which read the road ahead: theXF features all of the intelligent technologies needed to reduce driverworkload and make even the longest journeys feel effortless and stress-free.

Gettingto grips: All-Surface Progress Control

Even the most expert drivers can struggleto pull away smoothly on very low-friction surfaces such as snow, ice or wetgrass – especially in a rear-wheel drive car. From a hill start it can be near-impossible because even the slightest pressure on the accelerator can be enoughto break traction.

Conventional traction control systemsattempt to modulate what happens after the wheels begin to slip – and oftenthat’s too late. Which is why the XF features Jaguar’s revolutionaryAll-Surface Progress Control (ASPC) system.

Leveraging the knowledge built up overdecades of Jaguar Land Rover experience in off-road technologies, ASPC deliversa step-change in capability because there’s no driver input on the pedals: thedriver just has to steer.

ASPC works like a low-speed cruise controland can operate between 3.6km/h (2.2mph) and 30km/h (19mph). The system isactivated by pressing a button on the centre console after which, the driveruses the cruise control switches on the steering wheel to set the maximumspeed. The system then does all the hard work.

What makes ASPC so effective is that itdoesn’t just provide fine control of the throttle: it also uses the brakes inopposition to the throttle so that, from standstill, only very low enginetorque is applied to the driven wheels. This unparalleled capability ensuressmooth progress with little or no wheel spin.
