The New Jaguar S-TYPE

Jaguar S-TYPE

Jaguar added a Diesel model to the X-TYPE range last autumn and, as anticipated, this has proved very popular. In the final quarter of 2003, diesels accounted for one-third of global X-TYPE sales. In Europe, this proportion increased to as much as 80 per cent in some key markets, evidence of considerable pent-up demand for diesel among Jaguar customers. There is every indication that a similar latent demand exists in the S-TYPE marketplace, and with its all-new, high-technology, twin-turbo V6, the S-TYPE Diesel is perfectly poised to capitalise on this.

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 and the new S-TYPE Diesel is no exception. Ensuring maximum control of noise, vibration and refinement was one of the Product Development team’s primary goals – and they succeeded. The engine uses unique, dual-isolated mounts and its own final-drive assembly to soften take-up of the engine’s huge torque, together with sound-attenuating features such as the double-skinned sump and the elastomeric-isolated, composite cam cover.

"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-engined S-TYPE is offered with a choice of six-speed ZF automatic or a new six-speed ZF manual transmission. The transmissions are 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 that results 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.

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.
