Even though Jaguar is on the cusp of discontinuing its range-topping luxury sedan, the XJ, the British automaker has long been known for celebrating four-door non-crossovers in the way it knows best: by bestowing them with high-output V8 engines and sending them on missions to collect lap records. Jaguar's love of the sedan is what's allowed absurd creations like the XE SV Project 8 to see the light of day.

The sedan is obviously not for the masses, given that it's priced at $187,500 and limited to just 300 examples. But it also features a supercharged 5.0-liter V8 cranking out 592 horsepower and a built-in roll cage, making it a car that only wealthy track day aficionados will buy. But Jaguar must have assumed some of those aficionados would want a more discreet look to their cars to avoid looking like tuning fanatics with bad taste at every fuel pump.

That's why the loony bin that is the Jaguar Special Vehicle Operations division has just built this, a Touring version of the XE SV Project 8. Like it's sibling, it features a 5.0-liter supercharged V8 that sends 592 horsepower to all four wheels, enabling 0-60 mph to be dispatched in 3.3 seconds with acceleration ceasing only once the car hits 186 mph.

What's different about the Touring spec is that it loses the "regular" XE SV Project 8's adjustable aerodynamic rear wing and gains a more discreet fixed spoiler in its place. The front end is also complemented by a fixed front splitter that ensures aerodynamic balance is preserved. But there are more bragging rights to be had, since the four-seat Touring spec car will be limited to just 15 examples, making it the rarest of the XE SV Project 8s.

"Project 8 has received outstanding critical acclaim since its launch, demonstrating the Special Vehicle Operations team's ability to create a compact Jaguar sedan with supercar-rivaling performance," says Jamal Hameedi, SVO's engineering director. "Touring specification extends the appeal of Project 8 to performance car enthusiasts and collectors who prefer a more discreet appearance, without compromising its driver-focused on-road dynamics."

While Jaguar has yet to announce a price tag for the car, we hope it'll be cheaper than the more aggressive version of the Project 8. Interested buyers might be happy to know that the XE SV Project 8 in Touring spec can be had in four signature Project 8 paint finishes, including British Racing Green and Corris Grey Satin.
