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.

Watch the Chevy Corvette dismiss its Euro rivals at the hands of a Brit magazine

European auto writers, especially the British, have a bit of a reputation for favoring their own domestic cars over foreign rivals in comparison tests. Just think about how many times you've heard Jeremy Clarkson deify the latest product of UK loins while denigrating an American rival as a hopeless "Yank Tank." However, we have to tip our hats to the folks at Autocar because in its latest video comparing the 2014 Corvette Stingray to the Porsche 911, Jaguar F-Type V8 S and Audi R8, it's actually given the Vette a fair shake.
Autocar has put the Stingray through a battery of tests against what it considers to be the three best sports cars on sale in Europe today. And while the tests that it has chosen are somewhat random and subjective, it has concluded that the C7 can stand up against its rivals, even irrespective of its price. It's one thing to hear about how great the Stingray is from American writers, but it's great to know that not all Brits think we've gone crazy for calling the new Chevrolet "exquisite."
Scroll down to see how it all plays out on video.

How Jaguar optimized the Ingenium gas engine for the F-Type

At the 2017 New York Auto Show, Jaguar showed off the new entry-level F-Type, packing a 2.0-liter, turbocharged, gasoline-fueled inline-four that produces 296 horsepower, which is built in-house in the UK. It's the debut of this branch of the Ingenium engine series, and it's also the top of the Ingenium gas range; most JLR vehicles will offer a less powerful 247-hp version. We caught up with Jaguar's engineers to figure out exactly how this high-output Ingenium engine differs, and what Jaguar had to do to fit it in the F-Type's engine bay. While all Ingenium 2.0-liter gas fours share major architecture – the aluminum block and heads, as well as the bore and stroke – there are some internal differences. The most important are the low-compression pistons, which allow for more boost without detonation. The new compression ratio is 9.5:1, compared to the 10.5:1 ratio in the 247-hp spec engines. To make the most out of more boost, you need new plumbing and a way to get more fuel into the combustion chamber. So Jaguar fitted a larger twin-scroll turbocharger that's unique to this application. It features low-friction ceramic ball bearings – Jaguar says this improves transient response. There are also new fuel injectors and a fuel pump to accommodate the increased demand for gas in the high-output engine. On the back end, there's a unique exhaust system with active flaps to give it a louder bark when called for. Of course, some new hardware and more boost means the various electronic systems that control the engine needed changes. For one, Jaguar's changed the cam timing and valve lift mapping, as well as the ignition timing. The throttle mapping and transmission calibration have also been optimized for the new engine.

As far as the driver's concerned, the biggest change from the 247-hp engine to the 296-hp one – other than increased scoot – will be where the power peak is. The 296-hp engine makes peak power at a higher point in the rev range, which should reward drivers who generously prod the throttle and hold gears in manual mode. Remember, F-Types equipped with this engine will only be available with an automatic transmission. You should also remember that it's an excellent gearbox overall, with rapid, smooth shift characteristics, if the other 8-speed Jaguars are anything to go by.
