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.

Jaguar Land Rover and Cambridge have developed a touchless touchscreen

Jaguar Land Rover and the University of Cambridge are working on new touchscreen technology that eliminates the need to touch the screen. Counterintuitive, right? It’s called “predictive touch” for now, in part because the system is able to predict what you might be aiming for on the screen.  The video at the top of this post is the best way to understand how users will interact with the tech, but weÂ’ll do some more explaining here. You simply reach out with your finger pointing toward the item on screen that you want to select. ItÂ’ll highlight the item and then select it. HereÂ’s how it works, according to the University of Cambridge: “The technology uses machine intelligence to determine the item the user intends to select on the screen early in the pointing task, speeding up the interaction. It uses a gesture tracker, including vision-based or radio frequency-based sensors, which are increasingly common in consumer electronics; contextual information such as user profile, interface design, environmental conditions; and data available from other sensors, such as an eye-gaze tracker, to infer the userÂ’s intent in real time.” Cambridge claims that lab tests showed a 50 percent reduction in both effort and time by the driver in using the screen, which would theoretically translate to more time looking at the road and less time jabbing away at the screen. If the prediction and machine learning tech is good enough, we could see this resulting in a reduced number of accidental inputs. However, on a certain level it almost sounds more difficult to point at a screen while moving than it does to actually touch a section of that screen. Without using the tech and its supposedly great predictive abilities, we canÂ’t come to any grand conclusions. One comparison you may already be thinking of is BMWÂ’s Gesture Controls. ItÂ’s already been addressed with a subtle diss from Cambridge: “Our technology has numerous advantages over more basic mid-air interaction techniques or conventional gesture recognition, because it supports intuitive interactions with legacy interface designs and doesnÂ’t require any learning on the part of the user,” said Dr Bashar Ahmad of the University of Cambridge. Of course, this tech can be used for much more than just vehicle touchscreen control. Cambridge says it could be integrated into ATMs, airport check-in kiosks, grocery store self checkouts and more.

Road & Track names its 2013 Performance Car of the Year

Road & Track recently staged its first annual Performance Car of the Year test, pitting 13 new and updated performance cars against each other on track, then graduating the top six to a road test before picking a winner. Additionally, the magazine staff picked the best automobiles of the year in eight categories.
But first, let's cover the PCotY segment. Here's the list of cars brought to the comparison test: Audi R8 V10 Plus; BMW 435i; BMW M6 Competition Package; Chevrolet Corvette Stingray Z51; Ferrari F12 Berlinetta; Ford Fiesta ST; Jaguar F-Type V8 S; Jaguar XFR-S; Mercedes-Benz E63 AMG S-Model Wagon; Mercedes-Benz SLS AMG Black Series; Mini John Cooper Works GP; Nissan GT-R Track Edition; and Porsche Cayman S.
To find out the results of the comparison, head over to Road & Track's website or check the press release below, where you'll also find the magazine's top-rated vehicles in eight categories. Want more? Head over to the 2013 PCotY hub. But before you do that, take a stab at guessing the winner of PCotY (we'll give you one hint: it isn't a Porsche).
