The last Jaguar XJR made its debut at the 2013 New York International Auto Show, and at the time its boasted of a 550 PS output from the company’s 5.0 litre supercharged V8 engine. This time around the big Brit gains a tweaked version of the powerplant, and judging by its ‘575’ numerals inside and out, could produce 575 PS, matching the F-Type SVR.

Curiously, one of Jaguar’s more recent projects, the XE SV Project 8, produces 600 PS from a development of the same engine, although this XE variant is hand-built at Special Vehicle Operations (SVO) Technical Centre headquartered in Warwickshire, England.

There is also a great deal of contrast between the upcoming XJR and the XE SV Project 8. The latter a hardcore, stripped-out track specialist that can be optioned with a Track Pack which dispenses with the rear seats, replaces the standard front seats with carbon-fibre race items, four-point harnesses and a harness retention loop.

The XJR is a much more refined take on proceedings, as it steps into the realm of the S 63 AMG and Audi S8, where luxury and creature comforts aren’t discarded. Not a whole lot can be gleaned from the current teaser set of images, but the solitary interior shot suggests it will stay true to the high-speed luxury theme; the Jaguar XJR with 575 PS is slated for launch sometime in this third quarter.
