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 F-Type pitted against Porsche 911 Cabriolet by Tiff Needell

You knew it wouldn't take long and it looks like EVO is first onto YouTube with a battle between the 2014 Jaguar F-Type and the 2013 Porsche 911. Tiff Needell spends a few laps warming up the tires (read: drifting like mad) in each droptop before getting in a timed run to see who's champion and who's second best.
Before the bell rings, its the Porsche that's got everything to lose, the 50-year-old era-defining sportscar getting on with a 3.4-liter flat-six, 350 horsepower, a seven-speed manual and a 3,197-pound curb weight. Other sportscars, like the F-Type, continue to eye the 911 like a flag atop Everest that they plan to first touch, and then rip from its socket. The mid-trim Jaguar rolls into the contest with a 3.0-liter supercharged V6 with 380 hp, an eight-speed automatic with paddle shifters and a curb weight of 3,521 pounds.
The video below shows you what happens when you let all those numbers fight it out on the same stretch of curvy track. Check it out.

Jaguar design boss Callum reinterprets classic Mark 2 for himself [w/video]

As the man behind the styling of basically every Jaguar since the mid 2000s, two things should be known about Ian Callum - he's a big fan of the brand, and he can bloody well get whatever kind of Jag he wants.
His newest car, though, is not what you might expect. Rather than an F-Type or an XJ, Callum has gone old school, and commissioned a custom, resto-modded Jaguar Mark 2.
Designed by Callum and built by Classic Motor Cars in Shropshire, England, the Mark 2 was an 18-month project between the designer and the garage. The essentially new car draws its power from a 4.3-liter engine that's been pilfered and modified from an XK. It's mated to a five-speed manual transmission.
