Jaguar working on 700-hp, 200-mph hybrid F-Type?

After first driving the 2014 Jaguar F-Type in Spain this spring, we came away mighty impressed. Of course, if you had to pin us down for a top three wish list of what improvements we'd like to see, we'd probably hit you with something like: 1) Less weight. 2) Less weight and 3) Less weight. Oh, and if we're feeling presumptuous, maybe some additional transmission choices.
Despite leveraging aluminum for the body and chassis, this Jaguar is still a bit of a fat cat compared to its rival models from Porsche. We never felt like it was lacking for power in any of its three supercharged trims, least of them the 495-horsepower V8 S, which is a genuine madman. We knew the variants would come, though - a quick look at the rest of Jag's lineup provides all the evidence you need of that. And so we're not surprised to see word of a hyper-powered F-Type on the horizon, an R-S version. What is surprising, however, is a new report that put its motivation at over 700 horsepower and its top speed at 200+ mph. Us? We're just hoping the latter figure comes at least partially as a result of a hardcore diet.
This F-Type R-S news comes according to the rumormongers at AutoExpress, who expect the high-power Brit to come in coupe form, at least initially. We still haven't seen the debut of the fixed-head F, but plenty of spy shots suggest its arrival is imminent. Wildly, AE posits that Jag won't look for more displacement to gain power, it will instead radically downsize by using a 1.6-liter turbo- and supercharged four-cylinder and an array of electric motors. If that sounds familiar, that's because AE suggests the high-tech powertrain will be scavenged from the defunct C-X75 supercar program (interestingly, earlier reports suggested this combination would only deliver about 500 horsepower).

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.

Is the Jaguar XFR-S really worth $17k more than the XFR? [w/poll]

Adding performance to a car is rarely cheap - whether you're looking to do it yourself or rely on the factory to do it for you. In the case of the new Jaguar XFR-S, the cost differential over an already-impressive (and somewhat expensive) XFR is a stout $16,800. Auto Express recently got a hold of both cars to see whether that price pays off on the track.
For that price, Jaguar gives the XFR-S an extra 40 horsepower and 41 pound-feet of torque - for a total of 550 hp and 502 lb-ft - to go with a stiffer suspension, beefed-up differential and, of course, meaner styling. We don't want to ruin the results of the AE video, but right off the bat, the host says that you can feel the extra power of the XFR-S, but that it's not a "night-and-day difference."
Scroll down to see what happens when two high-powered Jags go head-to-head on a track. And then be sure to let us know whether or not you think the added money is worth it for the XFR-S in the completely informal poll below.
