The "XV" power unit is being developed by Engine Developments Ltd and MG Rover, and uses basic architecture from the existing JUDD V8 and V10 engine family. The V10 version powered the winning car in this year's Daytona 24 Hours race. The extensive re-design currently being undertaken on the V8 will effectively produce a brand new engine which is at present unique in having been designed specifically to suit the CART 12000rpm rev limit regulations for 2004, in addition to other requirements for performance in the region of 700bhp.

Engine Developments Ltd of Rugby has over 20 years experience of race engine design, development and maintenance and in more recent years has forged relationships with customers from the Formula 1 arena. Commenting on the agreement John Judd, managing director, Engine Developments Ltd said: "As a British engine manufacturer, we are delighted and very proud to be associated with MG Rover, one of Britain's best known and admired car companies. MG has a long and successful tradition that is second to none, in fact my first car was an MG TA! It therefore seems very natural to renew my association with the company, and we look forward to a long and successful partnership with MG in the CART series. I am sure both our companies will benefit from our participation in the series, and that we can maintain and extend the traditions of the famous MG name"
