2014 Jaguar XFR-S is the power and the fury

If there's something wrong about a sedan with a 550-horsepower supercharged V8, we don't want to hear about it. Instead, we want to marvel at the car in person, which is fortuitous because Jaguar has officially unveiled the 2014 XFR-S at the 2012 LA Auto Show. That blown 5.0-liter V8 dishes up a full 502 pound-feet of torque, which is good enough to shuttle the four-door to 60 mph in a scant 4.4 seconds. And, thanks to a start stop system and a few other fuel-saving tricks, the 2014 XFR-S gets away without being hit by the gas guzzler tax.
That's all good news, but we're just as excited about the fact that engineers managed to crank up the vehicle's chassis stiffness by a ludicrous 30 percent. Stiffer dampers and springs also give the car a little more poise, and a wide-open exhaust lets the whole world know you're kicking down their door. You know, in case the electric blue paint and wild body work didn't tip your hand. Check out the full gallery above for a closer look.

Jaguar to build 25 D-type racing cars to finish off 1956 production run

It's good to pick up where you left off, even if it's been more than 60 years. In 1956, Jaguar planned to built 100 D-type racing cars, but only 75 were completed. The missing 25 cars will now be built at Jaguar Land Rover Classic Works in Warwickshire, England, and they will all be built according to the original, authentic specifications. Customers can choose between 1955-style "Shortnose" cars and 1956-style "Longnose" versions; the prototype is of the latter specification. All of them will have the original six-cylinder XK engine, and they will come with a lot of Le Mans heritage, as D-types won the famous 24 hour race in 1955, 1956 and 1957. During their competition years, D-types were driven by such motorsport legends as Mike Hawthorn, Stirling Moss and John Fitch. This content is hosted by a third party.

Earlier, they announced they were building nine XKSS cars to finish off a production run that was cut short by a 1957 fire, and in 2015 the division built six Lightweight E-Types. The XKSS itself was strongly related to the D-type, as originally it was based on unfinished D-types sitting around in the workshop after Jaguar temporarily retired from racing. As Jaguar Classic's Engineering Manager Kev Riches says of the continuation cars: "Each one will be absolutely correct, down to the very last detail, just as Jaguar's Competitions Department intended." No pricing details have yet been announced, but they will surely follow the D-type's official debut at the Retromobile classic car show in Paris this week. 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:
