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.

2017 Jaguar F-Pace is on the prowl in Frankfurt [w/video] [UPDATE]

UPDATE: A previous version of this story indicated that rear-wheel drive was standard. This was incorrect. The F-Pace uses a standard all-wheel-drive system with a rear bias. The story has been edited to reflect this. After much teasing, Jaguar finally introduced the new F-Pace, the company's first ever crossover, at the 2015 Frankfurt Motor Show. Of course, we had to trek over to the Jaguar stand to have a look. As we already know a very great deal about the new F-Pace, we'll just recap some of the finer points. Prices for the five-place CUV begin at $42,390, which will score you a model with a 340-horsepower, 3.0-liter, supercharged V6. If you'd like the 380-hp version of that engine – along with a lot more equipment – prepare to pony up $56,700. The very cheapest way into the F-Pace, though, will be with the 2.0-liter, turbodiesel four-cylinder, which starts at $40,990, offers up a modest 180 hp, 317 lb-ft of torque, and an on-sale date of sometime late in 2016. An eight-speed automatic transmission is the sole gearbox for the two V6 models, although Jag hasn't said what gearbox it will pair with the diesel mill. The standard, rear-biased, all-wheel-drive system will feature brake-based torque vectoring that can switch up to an even 50:50 split. Adaptive dampers promise, meanwhile, promise a leaper-worthy handling character, while wheel sizes vary from 18 to 22-inch wheels. Speaking of that all-wheel-drive system, while this may not be a Land Rover, it still promises a degree of off-road ability. The wading depth is an adequate 20.7 inches, while the approach and departure angles are 25.5 and 25.7 degrees, respectively. As we said, that's not the equal to even the lowliest of Land Rovers, in this case the Discovery Sport, which can wade up to 23.6 inches, manage angles up to 25 degrees on approach, 31 degrees on departure, and features an advanced Terrain Response system. Those that were worried Jaguar's CUV would be stealing the thunder from the off-roaders at Land Rover – like your author – look to have been mistaken. Unsurprisingly, that handsome body is mostly aluminum, although there's some high-strength steel, and even a bit of magnesium and composite material, all of which contributes to a torsional rigidity on par with the lower-riding XF sedan. We have a wide lineup of live photos of the new CUV. Take a look, and keep an eye open for the F-Pace in dealers next spring.

Weekly Recap: Automakers rethink the definition of luxury

Variety is the spice of life, but it's becoming a prerequisite for luxury carmakers in the ultra-competitive US market. The Detroit Auto Show was strong evidence of this reality. It's not enough to offer attractive and well-appointed cars and SUVs anymore. Luxury brands that want to be competitive need to invest in everything from high-powered supercars to clever hybrids. To be relevant, you need to be green and mean – and everything in between. As General Motors product chief Mark Reuss said after the reveal of the 640-horsepower Cadillac CTS-V: "We are not leaving anything on the table." He was speaking for Cadillac, but he might as well have been speaking for the luxury car market. The CTS-V debuted in Detroit about an hour after Lexus surprised showgoers with the reveal of the RC F GT3 race car and then announced ambitious plans to return to competitive racing. That almost overshadowed the fact Lexus had just revealed another potent addition to its growing F line, the 467-hp GS F. View 20 Photos But for luxury brands, it's not just about maximum horsepower for well-heeled enthusiasts or decadent amenities for the Grey Poupon set. Strong competition from all corners has forced automakers to refine and expand their lineups in ways unforeseen even a few years ago. Case in point: Mercedes-Benz finally has an answer to the BMW X6, rolling out the GLE coupe in Detroit. The X6, which blends coupe-like styling cues with some of the functionality of an SUV, debuted in 2008. Back then it was a punchline, but seven years and more than 260,000 sales later, the X6's success has compelled Benz to respond. Mercedes – one of the strongest proponents of diesel technology – also debuted the C350 plug-in hybrid sedan, which promises a range of 20 miles on electricity, though fuel economy figures were not announced. The car pairs Mercedes' well-received 208-hp turbocharged four-cylinder with an electric motor for total output of 275 hp and 443 pound-feet of torque. Meanwhile, Infiniti will add the Q30 hatchback to its lineup by the end of the year, new president Roland Kruger reiterated in Detroit. It's expected to be joined by a crossover variant, and the additions will help strengthen Infiniti in the United States and abroad. "While we're expanding our product line, we're also expanding our market reach," he said. That's something echoed by Jaguar executives, who are preparing to launch the brand's first crossover, the F-Pace, in 2016.
