This classic Jaguar XJ has a 720-hp ungentlemanly secret

Forget Tawny Kitaen. If you want to make a Jaguar XJ rock, just do what this guy did: stuff a heavily modified and turbocharged General Motors V8 under the hood, and take it to the track.
The video calls this Series 1 XJ a sleeper, but with its open exhaust and obvious turbo whistle, the once-gentlemanly sedan is anything but. The owner says that the engine is GM LQ9 V8 that has been stroked to 402 cubic inches putting out around 720 horsepower with 12 pounds of boost (in standard form, this 6.0-liter V8 was used in the second-gen Cadillac Escalade). Check out the video below to see what that kind of power does for this classic Jaguar in the eighth-mile.

Jaguar lifts the tailgate on XFR-S Sportbrake

In the market for an amped-up Jaguar? Look for the letter R, adorning such performance models as the XFR and XJR sedans, the XKR coupe and convertible and the new F-Type R. But if it's bonkers performance you're after, you'll want to add the letter S into the mix as well. Jaguar uses the letters to connote its most hard-core performance variants like the two-door XKR-S and four-door XFR-S. And now it's applied them to the XF wagon as well, skipping the R treatment and going straight for the new XFR-S Sportbrake.
Leaked just the other day and headed for the Geneva Motor Show, Jaguar has now revealed its new power wagon in full. The XFR-S Sportbrake packs Coventry's ubiquitous 5.0-liter supercharged V8 engine boasting 542 horsepower and 502 pound-feet of torque. That's the same version that powers the XKR-S and XFR-S sedan (not to mention the F-Type R and XJR), and drives the rear wheels through an eight-speed automatic to rocket the estate to 60 in 4.6 seconds and on to an electronically limited top speed of 186 miles per hour.
That may be pretty quick, but doesn't quite stack up to the Mercedes-Benz E63 AMG S-Model 4Matic Estate whose 5.5-liter twin-turbo V8 offers up 577 hp and 590 lb-ft for a 3.6-second 0-60 time, or to the Audi RS6 Avant whose 4.0-liter twin-turbo V8 churns out 552 hp and 516 lb-ft for a 3.9-second 0-62 sprint. Though the Jaguar is only a little behind in output, it's a good second slower where it's measured. Granted that the Benz and the Audi are both all-wheel-drive where the Jaguar powers the rear only, but if four-wheel traction is how you get the power to the road, we wonder why Jaguar wouldn't fall in line. Particularly when the Jag's starting price in the UK (don't expect to see it imported here) is quoted at £82,495 - several grand more than the £76,985 RS6 but just shy of the £85,880 Mercedes gets for the E63 S-Model wagon in the UK (where the less potent 'base' version is also available as the cheapest in the bunch at £75,885).

2016 Jaguar XF mule spied in Germany

From our best guess, the Jaguar test mule shown in these spy shots could very well be our first glimpse at the next-generation Jaguar XF, due out around the 2016 model year. The current XF has been around for five years already (launched in 2008), and this mule is likely testing powertrain or chassis components for a new version of the midsize Jaguar sedan.
With what seems to be a stretched wheelbase and wider track, this is almost certainly not a mule for the 3 Series-fighting Jaguar XS. That being said, though, there is also the outside chance that this could be a mule for other future Jaguar Land Rover products including a production version of the Jaguar C-X17 crossover or the Jaguar-based Range Rover Grand Evoque. Only time will tell what these images truly foretell, but if nothing else, it proves that Jaguar is definitely staying busy these days.
