After a surprise yet brief appearance at last months Goodwood Festival of Speed with a little sideways action, we were hoping the sporting Jaguar XF-R would finally take a bow at the recent British International Motor Show, but we were left hanging. Further adding doubt, these latest spy images recently taken in the American desert suggest development is still going strong, so a debut in Paris this October is most unlikely. Los Angeles perhaps?

Despite initial reports of a beefed up version of the current 420bhp 4.2-liter supercharged V8 found in the SV8 XF, it is widely believed that Land Rover together with Jaguar have been working on a new series of direct injection 5.0-liter V8 engines for future top range models, and it is this engine in supercharged form that will power the XF-R to approximately 500-plus bhp. In order to compete with the German super saloons from Audi, BMW and Mercedes, Jaguar will need at least this much power.
