The diesel premium in our Jaguar XE quickly pays for itself

Our long-term 2017 Jaguar XE 20d AWD recently returned from a 2,000-mile road trip. My wife and I took a few days to visit her family in Auburn, Alabama, and it was the first real chance anyone has had to stretch the Jaguar's legs outside of Michigan. It was also a good opportunity to see what sort of fuel economy I could wring out of the XE's 2.0-liter turbocharged diesel. The diesel engine was the main reason I chose it over our equally lovely long-term 2017 Audi A4. For me, chasing fuel economy is a great way to stay focused on the road. The XE 20d AWD is rated at 30 city/40 highway and 34 combined. The drive to and from Auburn is almost entirely highway, so I knew matching the highway rating would be easy enough. The XE has a 14.8 gallon tank, so I was looking at a minimum of 600 miles per tank and four fills for the trip, counting the initial pre-departure fill. I had two main concerns: first, this was a new route, so I didn't know how available diesel would be along I-75; second, crossing the Appalachian Mountains was going to severely cut into my overall average. The first worry turned out to be a nonissue, especially as we went further south. Not once was I forced to go from station to station looking for a lone green-handled pump. People in the South love their Cummins, Powerstroke, and Duramax-powered trucks, meaning diesel pumps were plentiful. Rolling up in a Jaguar does garner attention, though. An older gentleman even asked if I knew that I was putting diesel in the car. It seems he didn't have much faith in my reading comprehension skills. The mountains were more of a problem. There was literally no getting around them, but were west of the highest parts, so it could have been worse. The indicated fuel economy dropped by 4 mpg on the way up, from 47 mpg to 43. Still, I managed more than 650 miles from a tank, though I was starting to push my luck. We filled up for the short final leg. By the time we rolled into Auburn, the display indicated 44 mpg – pretty damn good, I'd say. It held there for the entire trip. Calculating the actual mileage revealed the computer was generous by 2 mpg, but that's par for the course. Few automakers display precise numbers. The relative ease of getting this sort of fuel economy was complemented by the price of diesel. At each one of my four stops, diesel cost less than premium, the required fuel in all of the XE's gasoline engines. According to AAA, the same is true nationwide.

Land Rover knows where you're going and how you want to get there

Land Rover makes some of the most capable SUVs on or off the road, and some of the most luxurious too. But the British automaker isn't about to rest on those laurels - not when every other automaker assaults its territory with sport-utes of their own. That's why Land Rover has been working so hard on nifty new technologies from a depth-sounder in the door mirror of the Range Rover Sport an augmented-reality head-up display that makes the whole front of the car virtually disappear.
JLR's newest tech may not be ground-breaking, but its integration promises to make driving around town that much easier. The system syncs with the driver's smartphone and uses all manner of parameters - including driver habits, weather and location as well as the presence of other passengers - to make the commute go as smoothly as possible. Get into the car and it'll set the seat and mirrors for you. No big deal, because lots of cars do that. But it'll also set up the nav system to take you to work and the sound system to play your favorite music. Okay, getting more interesting.
Get in with your kids and it'll know not only that you've got to drop them off at school first (or remind you to pack their gym bag if they've got soccer practice after school that day) but that they might not enjoy that Chumbawamba album you've been listening to since college and it'll play something it knows you'll all enjoy based on your listening history. Then it'll switch back to Tubthumping once the kids are out, remind you of your morning meeting and alert those you're scheduled to meet with if you get stuck in traffic while finding you a better route to get there, monitoring fuel levels all the while and telling you if you'll need to tank up before you reach your destination. It knows if you like calling your mother on the drive to work and will lower the air suspension to make it easier to hop out once you get there.

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:
