Watch new Jaguar XF perform a literal high-wire act

Coming out with a new luxury sedan can be a truly daunting prospect. Make it too edgy and you'll risk disenfranchising what can often be a rather conservative customer base. Make it too conservative and you may fail to attract enough new customers or generate enough interest to make the endeavor worthwhile. Whether Jaguar succeeded in walking that thin line with the new XF is a matter of personal taste, blending as it does elements from the smaller XE and the outgoing XF it replaces. But in launching the new model, Jaguar didn't just pull of a figurative high-wire act – it did quite a literal one. To drum up support for its newest debut, Jaguar undertook the stunt depicted in the video above, stringing a pair of carbon-fiber cables some 60 feet above the River Thames in London. With some guide wires and counterbalance weights to keep it all in check, and a motion-picture stunt crew orchestrating it all, the new XF drove over 780 feet from one bank of the river to the other, setting a new world record in the process. Instead of thinking too hard about the whys (seriously, though... why?) and hows, we suggest you just watch the video above. Related Video:

Jaguar might not sell many XF Sportbrakes in the U.S., but here's why it's trying

One of the wonderful surprises of this year was when we learned that the U.S. would receive the XF Sportbrake wagon, and — less of a surprise — it's as much a looker as the previous generation. And while we're never one to look a gift car in the grille, it did seem strange that Jaguar would attempt to bring a wagon to the U.S., especially when it already had a similarly sized F-Pace crossover. So we spoke with Jaguar CEO Joe Eberhardt, Jaguar Design Director Ian Callum, and Jaguar's head of product planning in the U.S. to find out what prompted the company to bring the XF Sportbrake here. There were a few key reasons. One was simply that the folks at Jaguar really like the car, and they know that journalists like wagons. That doesn't exactly pay the bills for a car, but the enthusiasm is good. According to these people at Jaguar, though, they do believe there is a market for the car, and they expect to sell most of them on the coasts. Obviously, even if Jaguar sees a wagon market, it's still going to be much smaller than for crossover SUVs. But no matter how small that market is, Jaguar has an extra advantage for bringing the wagon here. The company knew it was going to make a wagon regardless of whether it would come to America, since the wagon market in Europe is so strong. In fact, Jaguar expects that half of XF sales in Europe will be Sportbrakes. So the majority of the engineering costs will be covered from those sales. The folks at Jaguar also told us that the car wasn't difficult to homologate for the U.S., so the cost of bringing it here was minimal. So in the worst case scenario that has the XF Sportbrake hardly selling in America, Jaguar isn't going to be seriously hurt. And if it's a success, then it's even more of a success. So the XF Sportbrake isn't purely a passion product, but that's OK. It means consumers have one more option to the multitude of crossovers in the U.S., and enthusiasts have the chance to own a super cool wagon. Also, although the XF Sportbrake is currently only available in America in top-level 380-horsepower S trim, Jaguar said lower trim levels and lower-output engines, all at lower prices, will be available here in the coming year or so. Meaning there will be even more ways to satisfy your wagon itch. Related Video:

Jaguar Land Rover proposes seats that scientifically massage your butt, for your health

Habitually sitting too long can degrade a person's health. Scientific research has proven that dormancy can increase the risk of obesity, diabetes, cardiovascular disease, deep-vein thrombosis, and metabolic syndrome, according to the Harvard Medical School. Although sitting can be avoided in many cases, such as using a standing desk at work, taking a seat is the only option when hopping in the car for a drive. Jaguar Land Rover (JLR) is hoping to address this negative aspect of cars with a new high-tech seat that the company says mimics the act of walking.  JLR calls the concept a shape-shifting, or morphable, seat system, and it is currently in a trial period with Jaguar Land Rover’s Body Interiors Research division. Using actuators built into the seat's foam, the seat will constantly be in motion with micro-adjustments that can be tuned to the needs of different people and body types. JLR believes it has created a system that recreates what is known as pelvic oscillation, a motion that can supposedly trick the brain into thinking the body is walking. In addition to helping to prevent internal health issues, JLR also notes that a sedentary lifestyle can degrade and shorten muscles in the legs, hips, and rear. If these muscles are worked on a regular basis, the chance and risk of injury and back issues could potentially be reduced. The new seats are just one of many car interior technologies JLR has explored. In the past, we've seen tech that tracks brainwaves and heart rates, creates augmented reality, helps prevent motion sickness, and helps stop the spread of germs. They've also taken the time to have an expert demonstrate the perfect seating position. Most of this stuff is experimental for now, but it's possible similar features could eventually trickle down to production cars, in time. See how the seat moves in the video below. Related Video:
