As recently as a few years ago, not a lot of people talked about Jaguar as a worthy contender in the full-size luxury sedan segment. But times sure have changed and not only has Jaguar completely reinvented itself, but the likes of BMW and Mercedes are starting to understand why messing with this cat with evil intentions may not be such a good idea anymore.
The 2014 Jaguar XJ is far from the unquestioned best in its segment, but it sure has some pretty sharp claws. A new distinctive design has turned the XJ into a head-turner and when you combine that with a plush and luxurious cabin and a hefty engine under its hood, it’s become apparent that when you’re looking for a loaded luxury sedan, you’re window shopping won’t be complete without taking a long and hard look at the Jaguar XJ.
That’s how far Jaguar has come and there’s no telling the heights it can reach once people start noticing the brand even more.
Updated 08/01/2014: Jaguar announced prices on the 2015 XJ and as expected they are the same as for the 2014 model year: $74,200 for the base V-6 version and up to $119,000 for the XJR Long Wheelbase. No changes were made to both the exterior and the interior.

The 2014 Jaguar XJ isn’t your dad’s old Jaguar. Nope, those boxy sedans are long gone and in their place, the British automaker has a luxury sedan that boasts of an aggressive stance, a sleek and aerodynamic body shape, and sweeping coupe-like roofline that its predecessors would definitely be proud of.
But the best thing Jaguar probably did with the XJ is to keep its designed relatively restrained. Sure, it could have gone the way of trying too hard and making it more distinctive, but it didn’t, opting for that modern classic look swept back look befitting a car of its stature.
Modest integration was also a key factor in the XJ’s design, particularly the plethora of exterior upgrades that you can do the XJ without the car losing its aesthetic appeal.

Once you go inside the cabin of the XJ, you’ll immediately smell the upscale luxury from all that fancy leather covers and trim. But here’s the thing, even with the cabin boasting of some materials you didn’t think could be put inside a car, it’s still ergonomically efficient, specifically the spacious front seats and the impressive legroom on both ends of the car.
If there’s a caveat to the XJ’s cabin, and really, it’s a necessary sickness for all luxury sedans with sweeping roofs, headroom at the back could be a problem for taller people, but not to the extent where it becomes increasingly uncomfortable.
At the front, the polished dashboard makes plenty of room for a neatly designed instrument panel with the standard infotainment display sliding integrated into all the cursory buttons in a one-piece, sliding design that properly divides both front seats..

For a car of its stature, the XJ has a pretty modest 3.0-liter, V-6 engine as its base powertrain. That produces 340 horsepower and 332 pound-feet of torque, good enough to hit 60 mph in 5.7 seconds to go with a top speed of 121 mph. It’s alright, but really it gets a lot better.
Customers can opt to go fully loaded and get the performance-oriented XJ-R, which comes with a 5.0-liter V-8 that packs an impressive 550 horsepower and 502 pound-feet of torque. It can hit 60 mph in just 4.7 seconds and the 174-mph top speed is well within the vicinity if you decide to stretch the cat’s legs.

Understandably, the 2014-2015 Jaguar XJ doesn’t come cheap. A starting price of $74,200 for the supercharged V-6 is the lowest amount you can buy the car for. But if money isn’t a problem, the XJR can be yours for a tidy $116,000.
The full-size luxury sedan market is where the big boys really come out and play and there’s no better player in that segment thatn BMW’s current-generation 7 Series.
The current 7 Series is offered in three versions: 740i, 750i and 760i. The 740i makes use of a 3.0-liter, TwinPower Turbo I-6 engine with 315 horsepower; the 750i features a 4.4-liter V-8 with 445 horsepower; and the 760i comes with a 6.0-liter V-12 with a monstrous 535 horsepower.
The current BMW 7 Series is priced from $74,000 for the 740i and peaks at $141,200 for the 760 Li version.
The current Mercedes S-Class was unveiled back in May 2013 when the model was updated with a new exterior and interior look, plus a new series of engines under the hood and since then, it has emptied more than a few bank accounts from drooling buyers the world over.
The S-Class offers a choice of two models — the S550 and S550 4MATIC — and both powered by a twin-turbocharged, 4.7-liter, V-8 powerplant that produces 455 horsepower between 5,250 and 5,500, and 516 pound-feet of torque between 1,800 and 3,500 rpm.
On the U.S. market the model is priced from $92,900.
It’s easy to see why a lot of people have gravitated towards Jaguars in recent years. The company has done a remarkable job in reinventing itself and no more is that evident than with the 2014 Jaguar XJ. It’s got a unique design, a tricked out and classy interior, plus a choice of engines that includes a massively impressive 550-horsepower V-8.
It still belongs in a market that has well-established contenders, but for the most part the XJ has done a good job in making itself a contender amongs all those elite luxury sedans.

The Jaguar XJ, which debuted for 2011, brings dramatic design and a decidedly sporty driving spirit to the large luxury sedan segment, along with a nearly bespoke-level of interior luxury. Traditional Jaguar attention to design combined with advanced user technology, and a distinctly sporty driving character; creates a unique proposition that distinguishes the XJ from premium luxury competitors.
The 2014 XJ range offers two wheelbase lengths, two supercharged engines, and Jaguar Instinctive All Wheel Drive™3. This all-wheel drive system, which debuted for model year 2013, is teamed exclusively with the 340hp 3-liter supercharged V6. An active torque-management system, Jaguar Instinctive All Wheel Drive offers a performance-oriented rear-drive bias and can shift power to the front wheels to either pre-empt or counter wheel slip.3 The XJ Supersport has been replaced for 2014 by the new XJR models, featuring an even higher-performance 550hp supercharged V8.
Coupled to the eight-speed ZF automatic transmission that was also new for 2013, the supercharged V6 delivers performance on par with the normally aspirated 5-liter V8 it replaces while offering better fuel economy. All XJ engines feature Intelligent Stop/Start system for improved fuel economy.
The XJ model line for 2014 includes standard and long-wheelbase (XJL) versions, the latter offering 44.1-inches of rear seat legroom, 5.1-inches more than in the standard-wheelbase model. The interior of the XJ is the most luxurious offered in a Jaguar, blending a wide choice of leather and wood finishes with the latest infotainment technology. Even with a very high level of luxury, the Jaguar XJ remains very much an agile and spirited driver’s car, thanks to lightweight aluminum construction, sophisticated suspension technology and standard 19- or 20-inch wheels, depending on the model and options selected.
In addition to the supercharged 3-liter V6, the 2014 Jaguar XJ line continues with a 470hp supercharged 5-liter V8 in the XJ Supercharged and introduces a 550hp supercharged V8 in the new XJR models.
Instinctive All Wheel Drive™ System
The Jaguar Instinctive All Wheel Drive™ system introduced for 2013 has proven popular in the XJ model. The system employs an active power transfer control technology that adds the benefit of enhanced all-season traction while retaining the sporty agility and steering feel of the rear-wheel drive version. Instinctive All Wheel Drive™ is exclusively paired with the supercharged 3-liter V6 engine3.
In dry-road conditions, the Jaguar all-wheel drive system normally sends most torque to the rear wheels to preserve the agile driving feel and response of a rear-wheel drive XJ. An active electronically controlled system, Jaguar Instinctive All Wheel Drive™ constantly monitors grip levels, steering and throttle inputs. Using special control algorithms, the system can proactively predict rear-tire slip. It can transfer up to 50 percent of the torque to the front wheels when needed, such as in slippery conditions, and also to pre-empt potential rear-wheel slip.
The Jaguar Instinctive AWDTMsystem offers other benefits, as well. When accelerating from a stop, the system applies "pre-load" torque to the front wheels to help optimize traction. Once underway, if no slip of the rear wheels is detected, Jaguar Instinctive All Wheel Drive™ seamlessly switches to its rear-biased configuration.
When selecting "Winter Mode" using the Jaguar Drive Control, the vehicle will optimize its systems for slippery conditions. Winter mode also preloads more torque to the front wheels at start-up and defaults to a 30:70 torque share between front and rear to maximize traction on slippery surfaces3.
Control is further bolstered by the full integration of the AWD control with Dynamic Stability Control and ABS, which can apply braking to individual wheels as a second measure against wheel slip and also apportion torque side-to-side3.
Jaguar All Wheel Drive System6 Components
A transfer case connected to the rear of the eight-speed automatic transmission houses a multi-plate wet clutch, which controls power transfer via a driveshaft to the front differential. The Transfer Case Control Module (TCCM) is the electronic control unit that monitors grip levels and driver inputs, and then signals the transfer clutch to apportion the torque appropriately.
To package the AWD system as efficiently as possible and retain a low center of gravity, the front half- shafts run through the engine oil pan. Special acoustic materials in the transmission tunnel ensure refinement comparable to the rear-wheel drive model.
Jaguar engineers spent 18 months testing the new Instinctive All Wheel Drive™ system in a variety of conditions, including the frozen lakes and split-friction coefficient surfaces of the Jaguar Land Rover development facility in northern Sweden.
Supercharged V6 and Eight-Speed Automatic Transmission
The supercharged V6 combines a broad powerband with high efficiency, along with the refined performance expected from a Jaguar engine.
All 2014 XJ engines are mated to a Jaguar-tuned ZF® eight-speed automatic transmission, which offers a broad spread of ratios for an optimally balanced combination of performance and efficiency and allows manual shifting with steering wheel paddles.
Jaguar engineered its DOHC 3-liter supercharged V6 from the all-aluminum architecture of the brand’s acclaimed 5-liter supercharged V8. As in the V8, the lightweight die-cast block is reinforced with cross-bolted main bearing caps to increase rigidity and therefore refinement. Counter-rotating front and rear balancer weights help the supercharged 90-degree V6 match the smoothness and refinement of the V8 on which it is based.
The 3-liter supercharged V6 provides performance comparable to the discontinued naturally aspirated 5-liter V8, but with better fuel efficiency. The Intelligent Auto Stop/Start system helps increase efficiency in urban driving situations. In the 2014 XJ, the V6 engine produces 340hp at 6,500 rpm. More telling about the powerplant’s flexibility in everyday driving is the broad torque curve, with the peak of 332 lb.-ft. available from 3,500-5,000 rpm.
The XJ 3-liter can accelerate the rear wheel drive standard-wheelbase model from zero to 60 mph in 5.7 seconds5.
Fuel economy, meanwhile, is an impressive EPA 18 mpg city / 27 mpg highway compared to 16 mpg city /23 mpg highway for the outgoing 5-liter V8 model2.
Like the Jaguar supercharged V8, the supercharged V6 combines high compression, direct fuel injection, dual independent variable cam timing (DIVCT) and an engine-driven supercharger to deliver performance of a larger-displacement engine. A Roots-type twin vortex supercharger is mounted in the engine’s "V," and a water-cooled intercooler reduces the temperature of the intake air to optimize power and efficiency.
The Intelligent Stop/Start system uses a twin solenoid starter, enabling the system to restart the engine in less time than it takes for the driver’s foot to move from the brake pedal to the accelerator. There is also a strategy for engine stop-start "change of mind" scenarios. As the engine is shutting down, but before it has completely stopped, it is able to restart by rapidly injecting fuel into the cylinders.
Meridian™ Premium Audio Systems
The 2014 Jaguar XJ models offer a choice between three premium audio systems from Meridian™, the renowned British maker of high-end home audio equipment and speakers. Meridian™ technology emphasizes ultra-low distortion, natural detail and realism. For example, a total harmonic distortion (THD) rating of less than 1 percent is considered to be high fidelity and inaudible to the human ear; the 2014 Jaguar XJ Meridian™ systems have a THD of just 0.2 percent.
That is one reason, along with Meridian™ proprietary digital signal processing, that the standard 380W system in the XJ 3.0 and XJL Portfolio models produces output on par with some 600W systems. The 825W system that is standard in all models with a supercharged V8 and optional in all others, produces the equivalent output of the 1,200W system used in model-year 2012 XJs, but with less power consumption.
The Meridian™ 380W premium sound system comes with AM/FM receiver, a single-slot CD/DVD player, MP3 disc compatibility, Radio Data system, HD RadioTM and a SiriusXM Satellite Radio™ receiver (with three-month complimentary service). In addition, the Media Hub provides flexible connectivity through a USB port, Bluetooth® v2.0
audio streaming and an auxiliary input jack4. Gracenote provides artist and track recognition.
Tuned by Meridian™ for the Jaguar XJ interior, the 380W audio system uses 14 speakers including two subwoofers, separate digital amplifier and Audyssey MultEQ sound equalization technology. The 825W version uses a 15-channel, 20-speaker surround sound system and adds the Meridian™ Trifield™ surround mode. This unique mode creates an all-enveloping sound field that places each occupant in the center of the sound field. Cabin Correction and Dynamic Volume Control maintain consistent volume level by monitoring extraneous noise levels and continually minimizing resonances.
For the ultimate in lifelike mobile audio, the XJ LWB models for 2014 introduces a third choice, the 1,300W Meridian™ Reference Audio system with a total of 26 speakers strategically placed around the cabin offering an uncompromised, personal and consistent musical experience for every passenger. With three additional speakers (two 80mm speakers and one 25mm tweeter) located in the rear of each of the front seats, the system provides rear seat passengers with a personal soundstage experience.
This top Meridian™ system integrates new Conversation Assist, which uses microphones located above each seating position to channel passengers’ voices through the audio system speakers, mixing music and speech volume accordingly, for clearer conversation.
The standard XJ navigation system provides a number of convenience-adding features.
The Dynamic Zoom feature automatically magnifies the image when the car is approaching an intersection or highway interchange. The Visual Lane Guidance function provides additional lane selection details at intersections, and the Road Sign Board feature displays overhead sign information in the split-screen view4.
The "My POI" feature includes easy access to the Points of Interest function from the main menu screen and the ability to download, import and edit POI lists from a personal computer into the navigation system via USB drive. There are fewer steps to set a destination, single/dual map view allows route comparisons, and the map viewing mode has been extended by moving soft-touch buttons to the periphery of the screen.
The Jaguar design language is exemplified on the XJ by a "face" defined by a bold mesh grille and slim standard Xenon headlights. The strong, muscular lower half of the car is contrasted with the slender and graceful quality of the roofline. The wrap-around rear window gives the impression of an exotic "floating" roof. A panoramic glass roof, standard on all XJ models, enhances the sense of light and space in the cabin.
The clean, elegant form of the leather-wrapped instrument panel sitting low across the vehicle dominates the cabin design. Bold architectural wood sweeps forward from the rear doors through the front doors, meeting at the upper dashboard center. An analog clock inspired by luxury wristwatches is located in the center of the lower dashboard. When open, the panoramic glass roof mechanism slides the front glass panel upward and outward, preserving headroom. The roof’s dark tint and reflective coating help limit heat gain, and twin power blinds provide another level of privacy and sun screening.
The Jaguar XJ employs interior electronics in luxuriously functional ways. The illuminated stop/start button pulsates like a heartbeat until pressed, when, as part of the "handshake" sequence, the JaguarDrive Selector™ rises from the center console. When the engine is stopped, the JaguarDrive Selector™ retracts automatically.
A 12.3-inch high-definition screen displays "virtual gauges" to provide the functions of traditional instrument dials. When required, the tachometer fades to temporarily display a required warning message or menu — for example, if fuel is running low, or to operate the Interactive Voice™ control4. When the driver selects Dynamic mode, the dials change to a red hue and feature a gear position indicator that glows red as the engine speed rises.
An 8-inch touch-screen display in the center console provides easy access to many of the functions, including climate control, audio, communications and standard navigation. The Jaguar Interactive Voice™ control system provides easy control of the standard Bluetooth®, navigation or audio systems4.
Aluminum Construction for Performance, Agility and Efficiency
The XJ is based on the renowned Jaguar lightweight vehicle architecture. Primarily aluminum, but also utilizing magnesium and composite alloys, it yields a significantly lighter and stiffer body structure than one built from steel. The construction technique employs the same aerospace-based riveting and bonding processes refined by Jaguar on the XK grand touring models and previous-generation XJ sedans.
Advanced Chassis Dynamis
The XJ sedan’s light but stiff structure provides the foundation for both the car’s sporting character and its supple, refined ride. The double-wishbone front suspension features weight-saving forged aluminum components and uses coil springs. The front subframe is directly mounted to the body for enhanced steering response and handling precision. The subframe-mounted, multi-link rear suspension uses lightweight cast aluminum links and self-leveling air springs.
The 2014 XJ models are fitted with 19- or 20-inch alloy wheels in seven designs, some with the additional option of a polished finish. The rear wheels are wider than the front wheels and use lower-profile tires, the "staggered" array enhancing the vehicle’s grip and agility.
The standard Adaptive Dynamics active damping system automatically tailors damper settings to suit both road conditions and the way the car is being driven3.
The driver can select how the system responds using the JaguarDrive control™, which offers three modes: Normal, for comfortable, leisurely driving; Dynamic, for a more sporting and responsive character; and Winter, for greater capability in low-grip conditions. Each mode changes the characteristics of engine response, transmission shifts, Adaptive Dynamics and Dynamic Stability Control (DSC) intervention (and Active Differential Control on XJ Supercharged and XJR models). In Dynamic mode, gearshift points are raised, and the suspension damping is set firmer3.
In Winter mode, the transmission selects second gear to help provide greater traction from a standstill and also lowers engine rpm and shift points. When selecting "Winter Mode" using the Jaguar Drive control™, the vehicle will optimize its systems for slippery conditions. On AWD models, Winter mode also preloads more torque to the front wheels at start-up and defaults to a 30:70 torque share between front and rear to enhance traction on slippery surfaces3.
The 2014 Jaguar XJ Supercharged and XJR models also employ Active Differential Control in the rear axle, which helps to improve acceleration and also enhances cornering ability. The clutch-type rear differential transmits torque to the wheel with the most traction. This proactive system differs fundamentally from conventional traction control, which uses the brakes reactively to counteract slip.
New XJR Flagship Model
New for 2014, the XJR replaces the XJ Supersport models, offering greater performance in both standard and long-wheelbase versions. Functional aerodynamic improvements are provided by a new front air splitter, aerodynamic rocker sills, an additional rear spoiler, and hood vents.
The XJR models’ 5-liter supercharged V8 engine delivers 550hp and 502 lb/ft of torque, making the XJR capable of sprinting from zero to 60mph in 4.4 seconds (0-100km/h in 4.6 seconds) and reaching an electronically limited top track speed of 174mph (280km/h) 5.
The Electronic Active Differential and Dynamic Stability Control systems have been calibrated to match the handling characteristics of the XJR, allowing the driver to fully explore the performance envelope3. Working in parallel with the differential, the ’Trac DSC’ setting of the Dynamic Stability Control system now offers the enthusiast driver more opportunity to explore the outer edges of the handling envelope. The steering hydraulics and calibration have also been engineered to enhance steering feel, response and feedback under all driving conditions.
When operating in automatic mode, the eight-speed automatic transmission can detect the manner in which the car is being driven by monitoring acceleration, braking, cornering forces, throttle application, brake pedal activity, road load, and kick-down request. On detecting a more enthusiastic driving style, the transmission will automatically make the gearshifts more aggressively and move the upshift point to a higher RPM. Steering wheel-mounted gearshift paddles allow manual gear selection.
Corner Recognition senses when the XJ is negotiating a curve, and the transmission will hold the correct gear for the exit. The transmission will also recognize when the car is performing a series of overtaking maneuvers requiring rapid changes in throttle position and, rather than upshift, will remain in a lower gear ready for the next demand for acceleration. The suspension system has been extensively tuned on both road and track, using the legendary Nürburgring circuit in Germany, the high-speed Rockingham circuit in England, and the winding roads of England and Wales. Jaguar Adaptive Dynamics actively controls vertical body movement, roll, and pitch rates through the use of continuously variable dampers3.
Lightweight, forged 20-inch alloy wheels use 265/35-20 front tires and 295/30-20 rear tires specifically developed for Jaguar in conjunction with Pirelli. The 15-in. (380mm) front and 14.8-in. (376mm) rear discs of the Jaguar High Performance Braking System are internally ventilated.
Customers can choose from an extensive exterior color palette for the XJR, including: Polaris White, Ebony, Ultimate Black, Stratus Grey, Lunar Grey, Rhodium Silver, Cashmere, Caviar, Carnelian Red, British Racing Green and Italian Racing Red. The five-spoke, lightweight forged alloy wheels come in either Sparkle silver or Technical grey finishes. The assertive appearance of the XJR is further enhanced with a gloss black front grille and lower intake mesh, with chrome surrounds.
The XJR cabin is equipped with Sport Seats trimmed in Jet Black leather available with an exclusive choice of either Ivory, London Tan or Red Zone inserts on the seat facings or simply Red Zone or London Tan contrast stitching. The seats are embossed with the ’R’ logo. Jet Black suede cloth headlining is standard. Interior veneers are available in either Carbon Fiber or Piano Black. The 825W, 18-speaker surround-sound system from Meridian™ is standard.
A full secondary bulkhead, laminated windshield and door glass, optimized body structure and exemplary aerodynamics endow the Jaguar XJ with a tranquil cabin. Luxurious leather adorns the main interior surfaces. Twin-needle stitching highlights seams on the seats, and each door panel integrates a storage compartment inspired by high-quality, hand-stitched designer briefcases.
A wide range of color and trim selections, accented by elegant switchgear and soft blue lighting, offers expansive interior personalization. Eleven different woods are available, depending on the model, with carbon fiber and piano black finishes among the choices.
The 2014 XJ 3.0 is equipped with a dual-zone automatic climate control system, while all other models have a four-zone system with separate controls and ventilation outlets for the left and right rear seat passengers. The XJ 3.0 comes with 12-way power-adjustable heated front and rear seats. Optional for this model but standard for all others, are heated and cooled active-ventilated front and rear seats.
Standard amenities on all XJ models include a heated steering wheel, power trunk lid with adjustable opening height; auto dimming side mirrors with heat and power-folding; a power-adjustable steering column; Jaguar Smart Key system™ with keyless entry and start; rain-sensing windshield wipers, and approach illumination.
The comprehensive set of active technologies of the 2014 Jaguar XJ include Anti-lock Braking (ABS), Dynamic Stability Control (DSC), Cornering Brake Control (CBC), Understeer Control, Electronic Brake-force Distribution (EBD), Electronic Traction Control (ETC) and Engine Drag Torque Control3. On models equipped with Adaptive Cruise Control (ACC), the Advanced Emergency Brake Assist uses the ACC radar to help calculate distance from and closing speed to the vehicle traveling ahead. The system is designed to pre-charge brake-line pressure to help reduce impact speed if a collision is predicted, and provide an audible warning to the driver.
