Refined and Sporting Diesel Power

The introduction of an all-new, state-of-the-art V6 diesel engine marks yet another milestone in the evolution of Jaguar's S-TYPE premium executive saloon.

The arrival of the twin-turbo AJD-V6 engine means that, for the first time,
S-TYPE buyers will be able to choose diesel power as an alternative to the existing petrol 3.0 V6, 4.2 V8 and 4.2 V8 supercharged engine options.

The addition of an advanced 2.7-litre turbocharged diesel V6 is one of several improvements in the new S-TYPE. Striking styling changes including a new rear-end design and a new aluminium bonnet, dynamic improvements, enhanced interior features and a wider choice of equipment, are among the highlights of a package of revisions announced in 2004.

Embracing diesel in the S-TYPE is a natural progression for Jaguar, with diesel engines now able to deliver the refined performance customers of the marque demand. The all-new AJD-V6 is a superb example of a state-of-the-art diesel engine and complements perfectly the advanced technical attributes and sporting character of the S-TYPE.

The engine's specifications make for impressive reading. The four-cam, 24-valve, twin-turbo V6 features second-generation common-rail direct injection and super-fast piezo-electric injector operation. Maximum power from the 2.7-litre engine is 153kW. Torque peaks at a heady 435Nm, which is actually higher than that of the S-TYPE's naturally aspirated 4.2-litre V8 petrol engine. Yet the diesel has 47 percent better fuel consumption. More crucially still, 80 percent of this torque is available from just 1500rpm through to 4000rpm.

This combination of substantial power and torque gives the new S-TYPE Diesel huge mid-range flexibility and refinement. True to Jaguar tradition, it is relaxed when cruising, yet pleasingly rapid cross-country - characteristics which are accentuated by a six-speed automatic transmission. Jaguar's S-TYPE Diesel offers very accomplished performance: the benchmark 0-100km/h sprint in 8.6 seconds. Top speed is 227km/h.

The S-TYPE Diesel also addresses environmental challenges; its CO2 emissions of 208g/km with automatic transmission. Combined fuel efficiency is 7.8L/100km, while in the highway cycle achieves 6.2L/100km. The model-year 2006 S-TYPE Diesel is Euro Stage IV emission compliant.

Why Diesel?

The diesel market in Europe has experienced consistent - and significant - growth over the past decade. In recent years, demand for diesel has increased dramatically in the premium market. Diesel now accounts for approximately 40 percent of sales across the premium segment in Europe.

The AJD-V6 Engine

As with all engines in the Jaguar line-up, the AJD-V6 has benefited from the expertise of engineers at the company's Whitley Engineering Centre. Delivering the performance and refinement that customers expect - and demand - is key to the success of any Jaguar. The new S-TYPE Diesel is no exception.

"Strong performance is an inherent characteristic of the new V6 Diesel engine, but the accompanying levels of refinement are even more impressive. I am proud that the Jaguar Product Development team at Whitley has done an excellent job."
Phil Hodgkinson, Jaguar Programmes Director

The diesel-engine S-TYPE is offered in Australia with only the six-speed ZF automatic. The transmission is developed to maximise both the performance and great flexibility of the twin-turbo V6 engine.

The 2.7-litre diesel engine will also be used in other applications, in line with the co-operative agreement on diesel technologies and development between Ford Motor Company and PSA Peugeot Citroën. However, S-TYPE owners will benefit particularly from the exceptional Noise, Vibration and Harshness (NVH) performance resulting from the efforts of Jaguar's engineers at Whitley.

Achieving an engine installation that satisfies or exceeds all engineering requirements is easier if the engine itself is exemplary and the all-new 2.7-litre AJD-V6 can lay claim to that accolade. Not only does it have class-leading specific power outputs, but the use of compacted graphite iron (CGI) in the engine structure ensures outstanding strength, durability and - of particular relevance in a diesel engine - low weight.

Because less material is needed to construct a CGI block than a conventional cast iron block, the engine can be both lighter and shorter. The result is that the engine in the new S-TYPE Diesel is the lightest unit of its type and size. It weighs just 202kg - only 15kg more than the equivalent petrol V6 engine.

In short, the new S-TYPE has a new diesel engine that provides exactly what Jaguar customers want: the best engine in the best car.

Summary

The all-new diesel model is a logical and welcome addition to the new S-TYPE range. It complements perfectly the 3.0-litre V6 and 4.2-litre V8 models, offering S-TYPE customers the choice of diesel power without sacrifice.

"The new S-TYPE Diesel delivers on all levels. Not only does it have the performance and dynamic abilities for which Jaguars are renowned, it also offers exceptional refinement and flexibility. This is a great engine in a great car."
Paul Walker, Chief Engineer, S-TYPE, Jaguar Cars

As with the rest of the range, the new S-TYPE diesel boasts attractive costs of ownership to appeal the premium segment buyer who expects strong value for money as well as style and performance - even from a luxury marque.

But perhaps most crucially, S-TYPE Diesel retains its unique Jaguar personality: a combination of bold, athletic styling, driver-focused performance, outstanding comfort and refinement, and unrivalled emotional appeal underpinned by outstanding driving dynamics.
