The story behind Bridgestone's new tires for the rare and beautiful Jaguar XJ220

The Jaguar XJ220 is a beautiful, fast, and arguably under appreciated supercar from the early 1990s. While contemporaries like the Ferrari F40 and Porsche 959 garner more than $1 million at auctions, the XJ220 might pull in half that. Maintaining an older car requires work, a task made more difficult when parts aren't available. Last year, Bridgestone announced it was producing new tires specifically for XJ220s. The Japanese tire supplier has released a 42-minute video documenting the process. There were only 275 XJ220s ever built, fewer than both the F40 and 959. Until recently, no supplier made four same-spec tires that would fit the XJ220. Early Dodge Viper owners suffer from the same problem. Thanks to both Bridgestone and Pirelli, owners now have two options to choose from. Bridgestone worked with Don Law Racing, the go-to shop for all things XJ220, when developing the right tire for the car. It isn't simply a reproduction of an older-spec tire. Bridgestone tested a number of new compounds. With so few cars available, from the beginning this was going to be a money-losing prospect for the tire maker. Enthusiasts within the organization fought hard to get everything approved. Watch the full video to hear how much time and effort went into the project.

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.

Latest Jaguar XJ snaps show old versus new

It is a rare day when automakers line up their current models and test cars right next to each other and allow us to compare them directly. However, Jaguar ending up doing just that during cold weather testing of the face lifted XJ, providing the perfect chance to see just what the company is changing.
We spotted the refreshed XJ testing last year, and it hasn't evolved much since then. The updated model sports clear turn signals and a slightly revised front air dam. The modifications are similarly minor at the rear. The bumper appears to dip down slightly further on the new sedan. Thankfully, those gorgeous taillights are still draped over the back of the car. The exhaust outlets have switched to oval shapes rather than the current parallelograms. This alteration could just be chalked up to it being a test car, but the previous tester we saw had a similar design. It's possible that the camouflage could be hiding other revisions, but don't expect anything radical from the facelift.
Our previous report indicated that Jaguar is also planning some interior upgrades with new infotainment and ambient lighting. The company seems to feel that there isn't a point in messing with the XJ's design just yet, since all of the changes we see here are very subtle. No problems, here - to our eyes, the big Jag is still one of the prettier sedans on the road today.
