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.

Watch Felipe Massa put the Jaguar C-X75 through its paces

Automakers who run their own racing teams enjoy the benefit of having top-flight professional racing drivers on call to help out with development work. Jaguar, unfortunately, has no such racing team, having sold its F1 operation to Red Bull back in 2004. So when it came time to put the C-X75 through its paces in this latest video, it turned to Felipe Massa. Why Massa, you ask? For one thing, having driven for so long for Ferrari, the Brazilian driver is used to applying his F1 skills in testing a supercar designed for the road. But since switching to Williams, he hasn't been called upon in that capacity. For another, it was Williams Advanced Engineering as much as Jaguar itself that spearheaded development of the C-X75. So Massa was the natural choice. The C-X75, for those who don't recall, represented Jaguar's plan to build a hybrid hypercar of its own. Having debuted way back in 2010 at the Paris Motor Show, the concept followed hot on the heels of the Porsche 918 concept unveiled earlier that year in Geneva – a predated by far the emergence of the McLaren P1 and LaFerrari. The original design called for a revolutionary powertrain combining a pair of micro-turbines and four individual electric motors in the wheels. When that proved unfeasible, Jaguar switched to a more conventional setup with a turbocharged hybrid powertrain. Unfortunately plans to put even that version into production were shelved. But the concept was revived for the filming of the latest James Bond movie Spectre. Check out the C-X75 being put through its paces by the eleven-time grand prix winner in the video above.
