2013 Jaguar XF 3.0 Supercharged

Generally speaking, I don't get too upset about the growing need to replace displacement in modern cars. Sure, there are exceptions (don't you touch my 6.2-liter AMG V8), but honestly, the industry's new forced induction powertrains are all lovely, and their gains in fuel economy - when they actually make good on them - can make up for the ever-so-slight losses in performance or driving character.
But I'm having a hard time keeping my chin up with this Jaguar XF. For the 2013 model year, Jaguar has killed off the naturally aspirated 5.0-liter V8 and fitted a supercharged 3.0-liter V6 with an eight-speed automatic in its place (and even offers a turbocharged four-cylinder engine below that). That all sounds perfectly well and good, but a week behind the wheel of this British Racing Green sedan just left me missing that V8. And then some.

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.

1956 Jaguar D-Type could top $5M at Arizona auction

The Jaguar D-Type is an essential element of the marque's history, one of its most successful racing cars, and one of its most beautiful creations. Chassis number XKD 604, pictured here, was the first of six long-nose Jaguar D-Types made for the factory team in 1956. They were, however, far from ubiquitous, with only 53 made for private customers, and another 18 campaigned by the factory racing team. More advanced than the examples that preceded it, this one was equipped with a de Dion rear suspension and fuel injection. It didn't have much of a distinguished racing career to speak of, passing from the factory to the Ecurie Ecosse team in Scotland which kept it in storage for years. After the team's closing, it passed through the hands of two British owners, undergoing a full restoration at the hands of the latter, before trading between two US owners. Although precise pre-sale estimates are available by request to interested parties, RM confirmed to Autoblog that this example "is expected to fetch more than $5 million when it crosses the auction podium in January." According to Sports Car Market, last year the same auction house sold a customer D-Type in Paris for nearly that much. However at its London auction in 2013, another works example failed to sell despite a high bid of over $6.2 million. If this one takes in more than that, it'll set a record for the type. If classic Jaguars aren't your thing, RM also has lined up an enviable roster of Ferraris. Included among them is a yellow '71 Daytona (estimated to fetch over $700k), a silver '91 Testarossa (~$250k), a rare yellow '95 F512 M (~$450k), and a pristine 2011 599 SA Aperta (~$1.3m). Porsche fans will want to check out the '76 911 Turbo (~$250k) and the soft-window '69 911 S Targa (~$225k). With the auction not set to take place until January 28 at the Arizona Biltmore, you can bet there'll be a good number of additional lots consigned between now and then.
