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.

Jaguar's XF diesel isn't just fuel efficient, it's the cheapest XF available

Jaguar announced the 2017 Jaguar XF will now offer the 2.0-liter turbocharged diesel the company introduced on the XE. In addition to returning an impressive 42 miles per gallon on the highway and 31 in the city, the diesel is the cheapest XF available at $48,445. This means that picking the oil-burner will save you $3,040 over the cheapest gas V6 version, which only manages 29 mpg on the highway and 20 in the city. With 180 horsepower, the diesel is significantly down on power compared with the base V6 model. As a result, the diesel moves slower. Jaguar estimates the base V6 is good for a 5.2-second 0-60 time and the diesel should be able to do the same in 8 seconds. However, that's the only real downside. Even with the slower acceleration times, the diesel still has a very usable 317 lb-ft of torque available from 1,750-2,500 rpm. Based on our test drive of a diesel-equipped XE, the engine also breaks the old diesel stereotypes. It's both quite smooth and responsive. Unless you seriously need that straight-line performance, the Jaguar XF diesel arguably makes the most sense. It provides significant price savings and better fuel economy. The diesel XF also joins the XE and F-Pace diesels, leaving just the XJ and F-Type as the only Jaguars without compression-ignition engines. The British automaker is planning to remedy that, as a Jaguar Land Rover executive said the company plans to also add a diesel XJ variant in the US, even in the wake of the VW diesel scandal.

2018 Jaguar XJR575 First Drive Review | Everyone loves an underdog, right?

The number is right there, nestled smack in the middle against the windshield in red: 575. In case you missed it, there are another four red 575s stitched into the seat backs. You might excuse Jaguar for the numerical ostentation, but with manufacturers taking the horsepower arms race nuclear, the 6-year-old XJR sure could use a hook. What better way to stand out than an engine output humblebrag? The $122,400 Jaguar XJR575 gains 25 horsepower for 2018 thanks to software recalibration, which helps scoot the 17-foot-long four-door to 60 mph in a claimed 4.2 seconds. I'm gunning the XJR575 along the mountainous passes near the Alvao Natural Park in northern Portugal to find out whether the upgrade is enough to keep this underdog relevant in the fevered pitch of the high-dollar sedan market. Glance at the Jag in profile, and you might doubt its athleticism. Though nearly identical in length to a long-wheelbase BMW 7-Series and Mercedes-Benz S-Class (and 1.8 inches shorter than the Audi A8L), the XJR575's sloping rear window and rounder styling lend it a somewhat lazier, more lavish appearance. It's also long in the tooth, this design having been first introduced in 2009, but it wears its age surprisingly well. Frankly, you just don't see XJ-series Jags as often as their strong-selling competitors, and that keeps them looking fresher, somehow. In contrast, the Germans have kept their exterior lines purposeful and contemporary looking, with more frequent redesigns furthering their cause. Climb inside, and the XJR's premium trim lends a bit more modernity to the familiar cabin. For starters, the diamond-quilted and perforated leather seats offer solid support, but they might be a bit firm for long hauls. Unlike other XJs, the XJR and R-Sport trims don't offer a massaging feature, an unfortunate sacrifice that is available on most, if not all, of the competitive set. The rear quarters do, however, offer enough legroom for serious stretching out. Tall swaths of carbon fiber trim the door panels while another thin rim of carbon extends around the dashboard, a design shorthand for sportiness despite the fact that the XJR is only available stateside in long-wheelbase form. An Alcantara headliner aids the high-end argument. A few aging elements show cracks in the facade, among them the ungainly seams at the dashboard's center and switchgear that's grown more than a bit long in the tooth.
