2013 Jaguar Models | XF and XJ

2013 Jaguar XJ
Posted by: CarbAdmin , January 10, 2013

Jaguar’s multi-award winning XF and aluminium-bodied XJ saloon ranges feature significant enhancements for the 2013MY.

2013 JAGUAR MODELS | XF AND XJ | GREATER CHOICE, EFFICIENCY AND TECHNOLOGY

Key features across the 2013MY XF and XJ ranges are:

  • All XF and XJ models offer significantly improved efficiency through a newly expanded powertrain range. Eight-speed transmissions are now mated to all engines
  • Meridian sound systems – first introduced to Jaguar with the exclusive XJ Ultimate model – are now available throughout the XF and XJ ranges for an unparalleled automotive audiophile experience
  • Technology upgrades introduce enhancements, new features and optimise ease of use for audio and infotainment systems across all XF and XJ models. Suspension enhancements for the XJ flagship further optimise passenger comfort

2013MY XF and XJ : Powertrains

AT-A-GLANCE 

  • Expanded engine choice sees two new highly efficient, forced induction petrol powerplants– 340PS Supercharged Petrol Engine and 240PS Turbocharged Petrol Engine – join the existing line-up of both naturally-aspirated and Supercharged 5.0-litre V8 petrols
  • Eight-speed automatic transmissions are now fitted to all XJ and XF variants for greater efficiency and performance
  • The supercharged V8 petrol engine has fuel economy gains of up to 11% with emissions reductions of more than 8%, while the naturally-aspirated V8 sees economy improvements of up to 8% with emissions down by more than 6% 

Powertrain introduction 

Having introduced a host of new technologies for the 2012 Model Year and following the two new highly-efficient forced induction petrol engines announced earlier in the year, Jaguar is once again broadening its global product offering and improving customer choice with its 2013MY XF and XJ ranges.

The acclaimed eight-speed ZF automatic transmission is now made standard across the entire XJ and XF range for all powerplants

Eight-speed transmission

The eight-speed ZF transmission is now extended across the entire XF and XJ ranges for the 2013MY offering better economy, reduced emissions and smoother acceleration compared to the previous six-speed equipped models

For all installations the transmission’s operating software has been specifically tuned to ensure it perfectly matches the power delivery of the engines to which it is mated and offers the sporting feel, precision and smooth shifting expected of a Jaguar

With both a wider spread of ratios and more even spacing between them, the gearbox provides more seamless acceleration both from rest and when overtaking, while fuel consumption at high speeds is reduced. Gearshifts are executed in just 200 milliseconds while driver intervention is possible through the use of steering wheel-mounted paddleshifts which allow multiple downshifts, allowing the desired gear to be selected almost instantaneously

The use of lightweight, compact components including a rear differential with an aluminium casing means there is no weight or packaging penalty when compared with the outgoing six-speed models, while efficiency is improved through the use of an improved pump design and greater control of the gear elements

 

5.0-litre V8 Petrol

Now in its third generation, Jaguar’s powerful and charismatic 5.0 V8 petrol has won plaudits across the globe in both naturally-aspirated and supercharged variants. This all-alloy engine features a host of technologies that allow it to generate its power in a highly efficient manner, including direct injection, dual independent variable cam timing and, in the range-topping forced-induction variants, a Roots-type twin-vortex, intercooled supercharger

In the XJ flagship, both the naturally-aspirated and supercharged versions lend the car performance that creates a new facet to its personality and this is now extended through the fitment of the eight-speed gearbox for even smoother and more impressive acceleration while the broader spread of ratios improve economy and emissions. The naturally aspirated engine sees a fuel economy gain of 8% over the EU combined cycle while its emissions are reduced by more than 6%. The supercharged range-topper achieves a fuel economy improvement in excess of 6% while its CO2 emissions reduce by more than 7%

The 510PS XFR sports saloon benefits from the same combination of eight-speed automatic gearbox allowing it to offer an unrivalled blend of efficiency and excitement. The car’s economy on the EU Combined cycle improves by 11% with its emissions reduced by more than 8% 

240PS Turbocharged Petrol Engine

Belying its compact dimensions and low weight of just 138kg, the new all-aluminium 240PS Turbocharged Petrol Engine has an astonishing specific output of 120PS-per-litre. It achieves this through a combination of innovative technologies which results in peak power of 240PS at 5500rpm and 340Nm of torque available between 2000 and 4000rpm

Its low inertia turbocharger ensures smooth, lag-free power – seamlessly delivered via the eight-speed transmission – while integrating the turbine housing with the lightweight, thin-walled exhaust manifold shortens the engine and catalyst warm up times, reducing emissions. Chain-driven variable timing of both exhaust and intake valves maximises the spread of torque and optimises fuel consumption at part throttle while delivering maximum performance at high revs

In the XF sports saloon this engine is capable of accelerating the car to 100kph in just 7.9 seconds and on to 241kph while at the same time achieving 8.9l/100km on the EU Combined cycle and CO2 emissions of 207g/km. In the all-aluminium XJ, this same engine accelerates the car to 100kph in 7.5 seconds and on to a top speed of 241kph while returning 9.3l/100km and 216g/km of CO2

340PS Supercharged Petrol Engine

Jaguar’s latest supercharged petrol engine, the 340PS Supercharged Petrol Engine, features new combinations of cutting edge technology allowing it to deliver a smooth, refined and thrilling 340PS at 6500rpm and 450Nm of torque between 3550 and 5000rpm. Dual independent variable cam timing (DIVCT) and spray-guided direct injection (SGDI) is allied to new spark plug orientation that aligns the electrode precisely for enhanced combustion efficiency. These features, allied to a compression ratio of 10.5:1, optimise power, torque and economy throughout the rev range

The latest twin-vortex Roots-type supercharger is mounted in the ‘V’ of the engine and features electronically managed boost control which offers operating efficiencies of up to 20 per cent

The 340PS Supercharged Petrol Engine is capable of accelerating both the XF sports saloon and XJ limousine to 100kph in 5.9 seconds and on to limited top speeds of 250kph. Both cars also return identical fuel economy figures of 9.4l/100km on the combined cycle and emit just 224g/km of CO2

N.B. All quoted fuel economy figures are EU mpg and EU l/100km.

2013MY XF and XJ : Meridian audio 

AT-A-GLANCE

  • Optional premium sound systems developed by British ultra-premium specialist Meridian, a world leader in audio technologies and digital signal processing
  • Available in two power outputs – 380W and 825W – both featuring multiple channel amplifiers and Digital Signal Processing software powering an array of loudspeakers
  • Meridian audio systems are benchmarked against real instruments and voices rather than competitors
  • Meridian apply Psychoacoustics research and experience to produce sounds so true to life that they are perceived as real by the listener
  • Meridian Trifield technology, featured on the top-of-the-range 825W Meridian Surround Sound System, delivers perfect surround sound to every occupant of the vehicle

Meridian

The 2013 Model Year XF and XJ mark the start of a new partnership – previewed in the flagship XJ Ultimate – for Jaguar with British audio experts Meridian. The company has been creating ultra-premium home sound systems for more than 35 years and worked closely with Jaguar’s engineers to integrate this expertise seamlessly into the luxurious environs of the XJ and XF interiors

The XJ and XF each offer two Meridian options. The 380W Meridian Sound System offers a 12-channel system which feeds 11 loudspeakers in the XF and 15 loudspeakers in the XJ. The top-of-the-range 825W Meridian Surround Sound System utilises 15 audio channels sending their information to 17 loudspeakers in the XF and 20 in the XJ

Meridian has pioneered a number of technologies that deliver sound reproduction that is second to none and has won plaudits worldwide. The company considers the vehicle cabin environment as a unique opportunity to create and engineer audio solutions, making Meridian the ideal audio partner. Unlike other manufacturers which test their systems against competitors, Meridian benchmarks the fidelity of their audio reproduction against the original source of the sound itself, whether a real instrument such as a Steinway piano or a professional singer

The basis of the Meridian philosophy is perfectly matching speakers and amplifiers, achieving premium sound quality without large power demands and avoiding overwhelming listeners with high volume. Meridian worked closely with both Jaguar and its suppliers to ensure that speaker construction utilises the latest techniques and materials and that they are perfectly placed within the cabin

Meridian’s proprietary Digital Signal Processing optimises the relationship between amplifier and speakers, with each receiving its own dedicated signal to achieve clear, distortion-free sound. The result is a Total Harmonic Distortion (THD) – the measure of accuracy of sound reproduction – of just 0.2% which is 50 times greater than the outgoing systems. By comparison, a THD of less than 1% is regarded as inaudible to the human ear

To optimise their sound systems to an automotive application in which the audio environment can change rapidly, Meridian refined their proprietary technologies and innovations specifically for automotive audio

The two range-topping Meridian Surround Sound Systems feature the company’s proprietary Trifield technology which creates an all-enveloping sound field, placing each listener at the centre of their own exclusive music experience, no matter where they are seated

In order to account for resonances that occur within a vehicle, the company created a detailed acoustic analysis of both models’ interiors to identify resonances and apply bespoke digital filters – Meridian Cabin Correction – to maximise definition

The Meridian audio systems accept a number of digital inputs such as MP3 players, CDs, TV tuners, and USB interfaces. As such, it was important that every source be accurately converted to maintain sound quality. Meridian’s Digital Dither Shaping seamlessly processes each digital input to maximise detail and quality whatever the source media

Dynamic Volume Control is also incorporated, which monitors extraneous noise levels within the cabin and smoothly and unobtrusively alters the system volume to account, for example, for an opened window or a rough road surface.
