According to AutoWeek, the XJ fitted with the supercharged 5.0L V8 will be badged the ‘SV8’. This will leave space for an eventual ‘XJR’ with an even more powerful engine as the new range-topping model for Jaguar.
While there aren’t any details of what Jaguar has in store for the XJR, we do know the company is developing advanced plug-in hybrid technology although this is unlikely to be used for a performance model. The XJR could simply feature the supercharged 5.0L V8 with more boost dialed up.
The new 2011 XJ is set to go on sale early next year and will feature both short and long-wheelbase variants. In the U.S., the range will kick off with a 250hp (186kW) 3.5L V8, and will be followed by a 5.0L naturally aspirated version with 385hp (287kW). Topping the range until the arrival of the XJR will be the aforementioned SV8 with 510hp (380kW) on tap.
