Jaguar models could rev with inline-six engines again

Rumors are swirling once again that Jaguar might return an inline-six engine to its lineup. Autocar claims Jaguar Land Rover will use the modular Ingenium engine family to create a 3.0-liter straight-six. The new motor will replace the automaker's current V6. As with the Ingenium 2.0-liter four-cylinder, JLR will likely offer the powerplant in gasoline- and diesel-fueled versions. A rumor in May 2015 also suggested JLR would create an Ingenium-based turbocharged 3.0-liter inline-six and a 1.5-liter three-cylinder unit. According to Autocar, the engine bay in the XE, XF, and F-Pace can already fit the longer engine. The automaker isn't talking, though. "We can't comment on future product one way or another," company spokesperson Nathan Hoyt told Autoblog. Jaguar built much of its performance legacy with straight-six-powered vehicles. While the C-Type and D-Type were winning races with the engine layout, practically every Jaguar production model used them as well. Today, straight-sixes are less common. BMW continues to use them, and Mercedes-Benz reportedly also plans to offer one soon. While Autocar's report is still just a rumor, the move to an inline-six could be advantageous for JLR. For example, using an Ingenium-derived design could simplify manufacturing by allowing the company to build the powerplant in one factory alongside the 2.0-liter version. Returning to a design with such an important heritage for Jaguar would also make life easy for the brand's marketing team because it could link the new engine to past racing glory. Related Video:

Check out King Charles III's $17.6 million car collection

King Charles III's coronation will take place in England on May 6, and being crowned a monarch comes with a long list of perks with four wheels. He will gain full access to the Royal Family's fleet of cars, which is valued at about GBP14 million (approximately $17.6 million). The two most expensive cars in the collection are nearly identical: they're a pair of Bentley State Limousine models (pictured) built for Queen Elizabeth II, King Charles III's mother, in 2002. Only two units were made, and they're both part of the Royal Family's fleet, so they're difficult to put a value on; it's not like one is going to end up listed on your favorite auction site anytime soon. British company Nationwide Vehicle Contracts, which compiled the list, estimates that each armored, 245-inch long sedan is worth at least GBP10,000,000 (roughly $12.6 million). Dropping below the eight-digit threshold, the second-most-valuable car in the Royal Family's fleet isn't really a car. It's the Gold State Coach, which Matchbox recently released a 1/64-scale replica of, and its value is estimated at GBP1.6 million (about $2 million). At 275 inches long it's even bigger than the Bentley limousine and it weighs about 9,000 pounds. It's 261 years old and designed to be pulled by eight horses, and has been part of every coronation since 1831. The rest of the Royal Family's vehicles are relatively mundane. There's a 1965 Aston Martin DB6 Volante that Queen Elizabeth II and her husband, Prince Phillip, bought for King Charles III on his 21st birthday. It's worth GBP1 million (about $1.2 million). The collection also includes a Rolls-Royce Phantom VI (about $627,000), a Bentley Bentayga (about $201,000), a Land Rover Range Rover long-wheelbase Landaulet ($133,000), a Jaguar XE (about $41,000), and a Land Rover Defender ($38,000). "Luxury cars have long been associated with the monarch and King Charles III, in particular, is known for his fondness of motor vehicles. His impressive collection features sentimental value with motors passed down from his late mother, Queen Elizabeth II, to cars bought for him by his parents," explained Keith Hawes, the director of Nationwide Vehicle Contracts, in an interview with CBS News. Being at the head of a car-making nation's royal family also comes with drawbacks: Every vehicle in King Charles III's fleet is British.

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:
