Jaguar’s most powerful XJ ever is no longer on sale in Europe. The automaker has quietly retired the brawny XJR575 flagship from its lineup about a year after the model’s debut.

The V8-powered luxury sedan is the latest in a long line of models killed off by the more severe WLTP emissions testing. A quick search on Jaguar’s UK and Germany sales websites reveals the XJ is now only available with the 300PS (296hp) 3.0-liter V6 turbo diesel engine.

The XJR575 is a niche model with small sales numbers in Europe, and Auto Express claims it doesn’t make economic sense for Jaguar to homologate it for the new emissions tests. Interestingly, the XJ is now diesel-only for the first time in the model’s 50-year history.

Jaguar’s flagship is likely to remain like that for about two more years when the ninth-generation XJ should arrive with all-electric propulsion. The XJR575’s discontinuation marks another sad premiere for Jaguar’s flagship — the withdrawal of the XJR nameplate introduced in 1994.

Along with the axing of the XJR575 and its 575PS (567hp) 5.0-liter supercharged V8 mill, Jaguar has also put an end to the 340PS (335hp) 3.0-liter supercharged V6 gasoline engine. Earlier this year, JLR deleted the latter unit from other models as well, including the Jaguar XE S and XF S, Land Rover Discovery Sport, Range Rover Sport, and Range Rover Velar.

Both V6 and V8 gasoline engines remain available in the United States, though, where Jaguar’s 5.0-liter supercharged V8 also offers a 470-hp variant.
