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.

Jaguar Heritage Driving Experience throws you the keys to the museum

As automotive journalists, we get to drive a lot of really cool, high-performance vehicles. It really is the single best thing about this job. However, our access to vehicles is generally limited to the newest offerings on the market. That means, much like the general public, we don't really get access to vintage iron.
Jaguar is trying to rectify that issue for journalist and enthusiast alike, with a new program called the Heritage Driving Experience. It allows British enthusiasts to pop into the brand's Warwickshire testing site, drop anywhere from 100 to 300 pounds ($160 to $480) and go for a spin in some of the brand's most legendary offerings. That includes the more typical classics, like the Mark 2 saloon and the E-Type sports car, but you can also pay for access to stunners like the XK150, XKSS and the race-spec D-Type. In addition to the classics, most of the tests include time in their modern successors. So an hour with the Mark II can be split with time in an XFR-S, while the E-Type is complemented by its spiritual successor, the F-Type.
Most of the events are limited to 30 or 60-minute sessions, although the brand does offer a half-day and full-day event. The former, the Jaguar Le Mans Experience, includes time in the C-Type, D-Type, XKSS and F-Type R. The full-day Grace and Pace Pack, meanwhile, gives you access to nine vehicles, covering a huge gamut. That means time in the C-, D- and E-Type, XK150, Mark II, XKR-S GT and F-Type R, among others. Not surprisingly, prices aren't listed for the half- and full-day pack. Much like Jag's finest cars, if you have to ask, you probably can't afford them.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
