Motor Trend pits Aston V12 Vantage S against Jaguar XKR-S GT in battle of the Brits

With the recent increase in higher-performance versions of already high-performance vehicles, like Mercedes-Benz and its AMG Black Series, the public is now gaining even greater access to speed and maneuverability. Two of the most recent sports cars to get their wicks turned up include the Jaguar XKR-S GT and the Aston Martin V12 Vantage S.
Both of these cars are the pinnacles of their lines, with the Jag lording over the XKR-S, XKR and XK while the Aston rules over the standard V8 Vantage S and V8 Vantage. Motor Trend has opted to pit the two rivals together for some thorough testing, and it just happened to bring along a few video cameras to capture all the action.
There's nearly 19 minutes of super hot sports car action below, so scroll down and enjoy.

Are you the Jaguar F-Type Coupe R-S?

It's no secret that Jaguar is working on a fixed-roof version of the F-Type roadster, but now it looks like it's also developing a high-performance model for said coupe. Captured sharpening its claws at the Nürburgring, this F-Type Coupe prototype could very well be an R-S or even a more track-ready R-S GT variant.
Our biggest clue suggesting the latter are its massive brake rotors with bright-yellow calipers - similar pieces are also found on the recently introduced XKR-S GT. This would make sense, since a report in May said that Jaguar is looking to create a full line of R-S GT models in a similar fashion as the Mercedes-Benz AMG Black Series. Missing from this prototype, though, are the telltale aero add-ons we seen on the XKR-S GT - go-faster bits like the latter's front fascia winglets and rear wing, though this model is obviously still being developed. Regardless of what this new grippier, quicker kitty is called, we say "Yes, please."

Jaguar Activity Key | 2017 Autoblog Technology of the Year Finalist

In principle, the Jaguar Activity Key is a good idea. It's simple, useful, and relatively inexpensive. Unfortunately, in our testing it was less than reliable. Here's how it's supposed to work: To lock the car, leave your keys and fobs inside the vehicle, and strap the band on your wrist. Then, within 30 seconds, place your banded wrist against the letter J of the Jaguar script on the back tailgate. When you come back, you can unlock the vehicle by pressing the tailgate opening button, then, again within 30 seconds, placing the Activity Key band against the J of the Jaguar script. We chose the Jaguar Activity Key as a finalist for our 2017 Tech of the Year award because it's an uncomplicated device with lots of potential customers. Jaguar says the wristband is "robust and fully waterproof." Swimmers, surfers, kayakers, hikers, and even couples out for a sunny-day picnic could use a feature like this wristband key. Plus, wearables are pretty new as a category in general, and even more so in the automotive space. We didn't go skydiving with it or anything (an activity Jaguar cites as a potential usage case), but we did dunk it in water with no ill effects. While it all sounds good in theory, actually getting the Activity Key to work effectively was unexpectedly difficult, especially when the cameras were rolling. We tried varying the timing between closing the door and using the wristband, as well as between using the tailgate button and the wristband. It worked about half the time, regardless of our process or who was wearing the wristband. Whether our issues with the wristband were due to interference, new-technology teething problems, or just electrical gremlins, the idea of purposely locking the keys inside an automobile without having a foolproof way to unlock it gives us reason to pause. The Activity Key is a $400 standalone option on the 2017 Jaguar F-Pace, but only on Prestige, R-Sport and S models. The least expensive F-Pace with Activity Key costs $51,095.
