2017 Jaguar XE: We'll miss our long-termer, but not its diesel engine

This may be automotive journalist blasphemy, but diesels aren't always a good thing. And I don't mean that from an emissions standpoint. Sometimes the diesel in question isn't a good engine, and/or is a bad fit for the cars to which they're fitted. Our long-term Jaguar XE diesel is a textbook case of both issues. The first issue becomes apparent from the moment the 2.0-liter turbodiesel four-cylinder fires up with all the clattering, tapping and ticking that can only come from a compression-ignition engine. It's far from the shaking and knocking of full-size diesel trucks of a few decades ago, but it definitely feels a generation or two behind other diesel cars. For instance, we had a diesel Chevy Cruze in the office, which was quieter and smoother than the Jaguar despite a base price roughly $10,000 less. It becomes a bit smoother and less raucous as revs increase, but the volume remains rather high, making it sound as though the engine is struggling more than it is. Though, to Jaguar's credit, the company has managed to keep virtually all engine vibrations from entering the cabin. Now, the diesel engine's voice would be less problematic if it provided some engaging performance, but, outside of the high fuel-economy numbers, there's hardly any to be found. This may seem surprising considering the Jaguar's 318 pound-feet of torque, but that torque figure lasts only briefly from 1,750 rpm to 2,500 rpm. After that, the torque rapidly falls off, and you don't see the Jag's meager 180 horsepower peak until 4,000 rpm -- not far off of the engine's roughly 5,000-rpm redline. As a result, the XE has adequate passing power and around-town shunt, but anytime you want to play with more revs, it faceplants. But at least it does nail, and even exceed, its 40-mpg highway fuel economy rating without trying. The faults of this diesel engine are then exacerbated by the fact that it's in such a smooth and fun car as the XE. It positively glides across rough city streets and highways, keeping the chassis steady and its passengers soothed. Coupled with a quiet cabin, the XE is a peaceful place to be. At least it would be if the diesel didn't rudely interrupt every time the throttle pedal is pressed. Through some sort of black magic, the XE handles about as well as it rides. The incredibly sensitive and accurate steering is superb. It feels like adjustment knobs on a high-end stereo -- weighted perfectly and fine enough to get it right where you want it.

Jaguar could still revive XK as luxury grand tourer

With the F-Type taking the lion's – or Jaguar's – share of attention lately, it would be all too easy to forget all about a Jag once known as the XK. But it existed, and it could once again. First introduced in 1996 as the XK8 to replace the old XJS, the XK survived for two generations. It was available as a 2+2 coupe or convertible and was powered by Jaguar's signature AJ-V8 engine. By the time it was discontinued just this past summer, the ultimate XKR-S packed as much as 542 horsepower. But though it had two more seats, the XK was rendered largely obsolete by the arrival of the nimbler, newer and arguably more stylish F-Type. According to Autocar, however, the XK could be reinstated with a more GT-like approach. The XK as we've known it, said Jaguar's Ross Varney to the British weekly, "straddled the GT and sports car segment, with more of an emphasis on the GT side but probably not enough." Varney was in charge of the F-Type project and was also responsible for a new project to replace the XK until it was shut down earlier this year. "We have plans to do lots more with the F-Type," said Varney, "but there will still be other areas we want to cover. We need to find the right way to deliver on them, and the XK could be one way of doing that." What Varney is saying, essentially, is that while the XK project may not be moving forward just yet, it could be revived in the near future. If it did, we'd be looking at a more accommodating and luxurious grand tourer, different from the F-Type that's more of a focused sports car. Think of it, then, as more of a Bentley Continental GT, but probably less expensive - or put another way, if the F-Type is a junior Aston Martin V8 Vantage, the new XK would be a (relatively) more accessible DB9. The intel sounds similar to what we heard when the most recent XK was being put out to pasture, but tells us that hope is still alive for those interested in a two-door Jag with room for the kids in the back.

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:
