“Jaguar Focus this year is on meeting the needs of our customers for cars that combine excellent value for money with a driving experience that you can get from a Jaguar. That is why the 2006 range XJ has been significantly upgraded to ensure that each guest will find a model to meet its needs. From the introduction of our famous 2.7-liter V6 turbodiesel engine to a host of other groundbreaking advances for every model, such as acoustic laminated glass and Bluetooth ® wireless connectivity, the new 2006 Jaguar XJ held at the forefront of the premium sedan market. “Bibiana Boerio, Managing Director of Jaguar Cars
The introduction of the 2.7-liter twin-turbo Diesel to the XJ range marks an important step for Jaguar’s flagship model. Following the very successful introduction of diesel engines for the X-TYPE model ranges and S-TYPE, the new XJ 2.7 twin-turbo Diesel means Jaguar now offers a diesel alternative in its range of sedans together to ensure that the brand can meet the growing demand for diesel cars in the European market. And of course the 3.0 V6 and three V8 petrol engines – 3.5, 4.2 and 4.2 liter supercharged – remain as impressive as ever.
The XJ already ranks as the most technically accomplished Jaguar has ever built. It is the first production Jaguar to be constructed with a lightweight aluminum monocoque structure, a unique feature that gives the XJ significant competitive advantages over its rivals. A lighter car means faster acceleration and shorter braking distance and frugal fuel economy and range, especially when combined with the latest diesel fuel. The aluminum monocoque design of the XJ offers improved stiffness and performance of security throughout conventional steel body of the previous model, which means the client benefits not only the weight gain associated with aluminum, but obtains added benefit of exceptional ride and handling as well as being extremely quiet and safe.
Jaguar XJ (2006)
Therefore the addition of the diesel engine 2.7 bi-turbo XJ range complements the underlying set so well. Lightweight aluminum alloy with a modern diesel bi-turbo product dynamic, with precise handling and exceptional refinement. Producing 207PS (152kW) EEC a diesel-powered XJ saloon accelerates to 60 mph in just 7.8 seconds, while a powerful wave of torque (435Nm) is available virtually throughout the powerband to ensure instantaneous acceleration in each report.
Yet the efficient diesel engine and light total weight of the car means low running costs thanks to a figure of average fuel consumption of 35mpg (8.1l/100km) combined cycle. With the addition of a catalyzed diesel particulate filter (CDPF), the advanced design of the V6 engine ensures it exceeds Euro IV emission requirements stage.
A host of intelligent technology works in harmony with the driver and passengers to ensure optimum ride comfort on every trip. For example, electronically controlled air suspension self-leveling is standard on all models.This automatically reduces the car at a speed to provide remarkable high-speed stability and improve aerodynamic efficiency.
Jaguar renowned Computer Active Technology Suspension (CATS) uses computer technology and sensor feedback to automatically adjust damper settings. The result is a unique combination of maneuverability, ride comfort and excellent driver control.
noise intrusion into the cabin is reduced to a remarkably low level with the Integrated acoustic damping. This uses high acoustic absorption on the underside of the lid, seals between the engine compartment and hood structure and a new double-skin bulkhead to dramatically reduce engine noise inside the cabin.
For the first time on all XJ models, acoustic laminated glass further reduces the intrusion of outside noise in the cabin. The 2.7 twin-turbo Diesel XJ also sets an industry first, being the first car in its class to feature electronically controlled active engine mounts, which cancel 90% of engine vibration at idle. The result is a car that offers the refinement of best-in-class.
The 2006 XJ range also features a host of new features that are included as standard on all models. Subtle changes in the exterior trim of the car give it a more contemporary feel while a range of driver aids such as the Tire Pressure Monitoring System, Automatic Speed ​​Limiter and Bluetooth ® wireless connectivity creates an environment more secure and more relaxed .
Jaguar has achieved remarkable success in the JD Power and Associates Initial Quality Study released in May in the United States. Improving the overall second place, Jaguar top of the poll as the highest ranked European nameplate. Jaguar Halewood plant, where the X-TYPE is manufactured, also received the Gold Award from JD Power for the performance of European plants.
“The addition of the excellent new 2.7-liter twin-turbo Diesel to the XJ range reinforces the fact that our 2006 models are not only the most technologically advanced cars Jaguar has ever made, they rank among the best cars produced around the world, “said Joe Greenwell, chairman and CEO of Jaguar Cars. “This is the position Jaguar now holds in the premium car market and the introduction of the new XJ 2.7 twin-turbo Diesel reinforces that stronghold.”

Coinciding with the introduction of the new XJ diesel are a host of additional improvements to 2006 Model Year XJ models. Widely regarded as the show’s finest premium on sale today, significant advances to all new XJ ensure that the car retains that position.
Jaguar is the first manufacturer in the premium vehicle sector to introduce acoustic laminated glass. This glass reduces wind noise and engine noise levels of up to 5 decibels above standard laminated glass. Jaguar is also the first manufacturer to offer a hood liner with integrated side seals which further improve noise levels in the cabin.
Similarly, driver’s airbag is now isolated from the steering wheel, which significantly reduces the level of vibration transmitted to the driver.
In addition to ensuring Jaguar customers own one of the finest cars in the world, the addition of several new technology features on all models (depending on market) guarantees they also own one of the safest. All XJ is equipped with 19 standard and 20-inch wheels and – depending on the market – use Jaguar’s Tyre Pressure Monitoring System (TPMS) which assists the driver by highlighting an excessive loss of pressure tires of the vehicle.TPMS measures the pressure in each tire on the safety issues and if any of the pressures deviate to a significant level.
A speed limiter automatic (ASL) feature can be used by the driver to select a maximum speed limit of vehicles. This is a feature that is built into the system during speed control. When the ASL was created, the throttle will respond to the request of the driver until the limit is reached. At this stage, provided that the throttle position is sustained, the vehicle will maintain the set speed. The ASL system can be canceled by switching to cruise control, applying kick-down on the accelerator pedal or by pressing the cancel button. ASL is used separately rather than in collaboration with the Adaptive Cruise Control (ACC) system.
Aware that safe and legal mobile phone usage is vital for almost all of our customers, Jaguar introduced Bluetooth ® connectivity to the XJ as an option in model year 2005 (when enabled license) in replacing the previous fixed phone solution.
The system was developed by Jaguar in collaboration with Motorola and is compatible with a number of current Bluetooth ® handsets (depending on market). The main advantage of Bluetooth ® is the integration of flexibility and simplicity it offers, providing primary phone functions while interacting with the vehicle on board controls such as steering wheel, audio system, screen Touch and control JaguarVoice (if any). The phone can be left in the driver’s bag or pocket and need not be anchored in the vehicle.
Calls can be operated using the steering wheel controls and audio or touch-screen keyboards. The audio will be muted and the microphone dedicated carried over from previous systems, switched on. Voice commands can be used when the system is equipped with optional JaguarVoice.
JAGUAR acclaimed 2.7-liter V6 DIESEL – ENGINE WITH ACTIVE MOUNTS
The combination of a modern turbodiesel engine and aluminum body very advanced XJ range offers an outstanding performance, dynamics, refinement and economy. All the advantages of modern diesel engines – energy efficiency, power delivery and impressive car relaxed – are amplified by connecting them to frame a super-strong and lightweight, like the XJ.
Launched in mid-range Jaguar S-TYPE saloon in 2004, Jaguar state of the art twin-turbo V6 Diesel sets new standards in refinement and performance. The highly efficient engine, 24-valve features advanced technologies including the latest generation high pressure CommonRail, fuel system with direct injection and a lightweight, compact graphite iron (CGI) cylinder block.
The strength and durability of CGI means that less material is required than for a conventional cast iron block, ensuring reduced engine weight and length. In fact, the new diesel engine is the lightest unit of its category, only 202 kg. This contributes greatly to the excellent power to weight ratio and fuel economy.
Other features at the heart of the engine to provide the ability to offer high performance and excellent durability. Cooling cast aluminum pistons incorporate ‘double wave gallery. In this process, oil is sprayed precisely onto the inside of the pistons, jets in the block. The oil then flows through two internal channels in wave form to help cool each piston. This arrangement also has the indirect benefit of reducing “slap” piston noise.
Management characteristics of engine noise has focused particularly on injector tick and combustion noise, which is controlled by the use of technology CommonRail next generation, including injection multi- and control point injection closed loop, ensuring that the combustion is smooth under all conditions of operation.
The fuel quantity provided by each injector is controlled by a piezoelectric actuator, which allows high precision fuel metering of up to five injections per cycle. These features allow for extremely fine spray of diesel, which ensures the mixture as homogeneous as possible air-fuel, which causes more complete combustion process. Accordingly, the diesel engine is able to achieve both high power and capacity required emissions.
From the outset, the 2.7 twin turbo diesel engine has been designed to meet future emission levels. However, further progress in reducing emissions since the launch of the S-TYPE diesel twin turbo were made by changes in fuel injection system, using higher injection pressures and different spray patterns injector. The calibration of the electronically controlled turbocharger, the exhaust gas recirculation and deactivation of the port have also been revised. With the addition of a catalyzed diesel particulate filter (CDPF), the advanced design of the V6 engine ensures it exceeds Euro IV emission step requirements.
Help both the performance and emissions is a forced induction system, comprising twin turbochargers with electronic control on the state of the art. Traditionally, turbochargers are vacuum actuated, but this new form of rotary electric actuator gives a degree of control, providing services in the areas of emissions and transient engine performance, as well as in balancing performance and emissions between the two cylinder banks. The turbochargers are a low inertia type for quick delivery and reactive power.
The aluminum alloy heads high quality cylinders have four valves per cylinder and double camshaft. This combination provides optimum induction and exhaust actuation, with resulting benefits in performance and emissions.The design of the cylinder head includes a port deactivation system and pistons with toroidal combustion chambers, producing a highly efficient combustion capability. A low – by diesel standards – Compression ratio 17.3:1 combustion helps improve the quality of programming quieter, and compatibility with the single engine forced induction system. In a diesel engine, reduced compression means less heat buildup in the piston bowl and more efficient fuel burn, resulting in lower levels of pollutants.
Revised secondary bulkhead structure has been introduced into the engine compartment of all XJ models – both diesel and petrol – to reduce noise levels within a maximum of 5 decibels. The result is the most refined vehicle in its class for interior comfort.
The XJ Diesel is also the quietest vehicle in its class for exterior noise, with noise levels measured by the vehicle cerification Agency being 7 decibels (A) less than the legal limit of the EU for diesel vehicles. To achieve this goal, the exterior noise package has been significantly strengthened.
The XJ 2.7-liter twin-turbo diesel is the best in its class for the isolation of engine vibration at idle. This is achieved with active engine mounts, which are introduced on all 2006MY XJ Diesels and are an industry first. The engine mounts were designed and developed in conjunction with Avon Automotive. Diesel engines produce much higher levels of vibration than their petrol equivalents, which explains why the mounts are mounted on the XJ Diesel variants. Active mounts use an electronic control system and a tension mechanism to cancel an additional 90 per cent of the engine vibration at idle.
A system that allows you to cancel more than 90 percent of engine vibration at idle in the car has a huge impact on the vibration levels experienced by vehicle occupants. This technology, together with other noise, vibration and harshness (NVH) improvements, ensure that Jaguar delivers first-class levels of refinement for the XJ Diesel never first.
Significantly lower cost of ownership than RIVALS
During the development of the XJ 2.7 twin-turbo Diesel, Jaguar’s engineering team worked closely with our customer service organization to provide excellent cost of ownership figures. The advantages of a diesel XJ increased mileage interval service standard on petrol models resulting in a saving of approximately 7 percent of routine maintenance costs over five years.
Cons diesel competition – in the form of the Mercedes S320 Cdi – the cost of routine maintenance should be an impressive 27 per cent less for diesel XJ. Similarly, wear and cost index relative to the Audi A8 3.0 TDI and Mercedes S320 CDi are forecast at 25 and 28 percent lower respectively.
“Our new XJ diesel model is fast, refined and economical,” says Bibiana Boerio, Managing Director of Jaguar Cars. “Our customers appreciate the fact that it is a luxury sedan that makes no compromises. We are not asking them to trade performance for refinement or economy for power. This is a true Jaguar XJ, like all other models in the range. “
Development of Variable Geometry Turbo, was motivated by the need for a faster response to overfeeding.
