The RD-6 Concept was built by a small team of designers and it was a a break from tradition for Jaguar, the diesel engine being one of the more unusual features.

The RD-6 was unveiled in 2003 at the Frankfurt Auto Show. The RD-6 coupe is in fact a four door sedan, incorporating a similar layout configuration to Mazda's hot new RX-8. From the S Type-R-esque chain-link armor grille and ridged hood it's clear that Coventry's latest is a true Jaguar. However, breaking with tradition Jaguar has chosen to modify its requisite four rounded upright headlamps, tying them together in the middle and bringing the centermost pair to a downward point.
