Although Tata is not in a position to sign off on the development of new models at this point, it reportedly received the sportscar project with the most enthusiasm. While executives reportedly favor basing the Porsche rival off the XF's steel chassis, Coventry engineers are pushing to modify the XJ's aluminum platform; the engine bay would be able to accommodate both V6 and V8 engines. Jaguar also presented its hosts with plans to lop off two doors and a couple of inches of roofline from the new XF sedan to make a coupe version, although a convertible variant was ruled out. Lastly, and perhaps most dramatically, a plan was presented to lengthen the XK coupe and add two more doors to build its own rival for former corporate cousin Aston Martin's upcoming Rapide. This last development contradicts earlier reports that suggested the next XJ sedan would adopt the four-door-coupe approach, offering instead that the new XJ would include more interior space than the model it replaces.
