The Jaguar R-D6

Sir William Lyons founder of Jaguar Cars

Observers will point to 'classic' Jaguar design cues – such as the grille – on R-D6, but it is important to realise that such features are there not because they commemorate Jaguar's past, but because they are intrinsically 'right' for a thoroughly modern Jaguar.

R-D6 also takes advantage of Jaguar's lightweight structure strategy, as pioneered in the new XJ saloon. Using aluminium and composite materials for the chassis and body, R-D6 weighs just 1500kg. This allows it to capitalise on the power – and, more importantly, the torque – delivered by its V6 engine.

And it's the engine that will surprise many people – although, when you think about it, a high-performance 2.7-litre diesel engine makes perfect sense. Confirming Jaguar as a potent new force in the world of large-capacity diesels, the bi-turbo V6 is a tuned version of the engine that will make its debut in the S-TYPE in 2004. With horsepower in excess of 230bhp and a massive 500Nm of torque, the V6 diesel engine endows R-D6 with the pace to satisfy its looks and R-Performance rating. Acceleration from standstill to the benchmark 60mph takes less than six seconds. Top speed is an electronically limited 155mph.
