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.

Jaguar tests autonomous vehicle technology with 100-car fleet

Jaguar Land Rover is exploring how to take autonomous vehicle technology off the paved path. But the company has plans for technology on tarmac, too. The company announced that the Jaguar division will have a fleet of 100 cars testing autonomous technologies on public roads. The testing process will cover a period of four years and begin with vehicle-to-vehicle and vehicle-to-infrastructure communication systems, along with a stereo camera system and autonomous vehicle software. These systems will work together to provide a variety of features that could make their way into future Jaguars and Land Rovers. The first feature in development is called "Roadwork Assist." The system relies on the stereo camera to create a 3D image the car's software can analyze. The software can identify road cones and other barriers associated with construction sites. The car will then alert the driver about entering the construction zone and provide some steering assistance to keep the car centered in its lane. Tony Harper, Jaguar's head of research, said that this system can reduce stress on the driver, and the technology could eventually be used to allow the car to pilot itself through construction zones. Another of Jaguar's proposed features is "Safe Pullaway," which also relies on cameras and software. The Safe Pullaway feature is designed to prevent close-proximity collisions in traffic jams and even in the garage. To do this, the car watches the area immediately ahead of it for obstacles. If the car detects something nearby while the driver adds throttle or shifts into gear, it will apply the brakes to prevent driving into the object. The final project on Jaguar's plate is its "Over the Horizon Warning" system. This will be one of the first features to rely on Jaguar's vehicle-to-vehicle communication technology. The idea is that connected cars in constant communication will give drivers additional warning of upcoming hazards, such as out-of-sight animals and slowed or stopped cars. In Jaguar's example of a stopped car, the stationary vehicle would send a signal alerting approaching cars of the situation. In turn, the approaching vehicles would trigger audible and visual warnings to drivers about the hidden car. Jaguar says that the system could also be applied to emergency vehicles. Emergency vehicles would broadcast a signal to alert drivers well before the lights and sirens get their attention. This would give emergency vehicles a faster, safer path through traffic.

Jaguar XJ220 leaps into Jay Leno's Garage

Having sadly canceled the C-X75 project and sat out today's hybrid hypercar race, it would be all too easy to forget about Jaguar as a supercar manufacturer altogether. But back in the early '90s, the British automaker didn't just play in the supercar game – it dominated it. The XJ220 was, for a time, the fastest car in the world. Jay Leno pays tribute in this latest video. Originally envisioned with a V12 engine and all-wheel drive, the XJ220 ultimately surfaced with a 3.5-liter twin-turbo V6 driving the rear wheels alone. None of that kept it from eclipsing the top speed achieved by every supercar that came before with a terminal velocity that didn't quite reach the 220 miles per hour initially promised, but came pretty darn close. The disappointment in the change of specification lead some to dismiss the XJ220 as a failure, but it was still the fastest thing on the road until another British supercar (in the form of the McLaren F1) took its place at the pinnacle of automotive bragging rights. Two decades later, Jaguar quite nearly drove down the same road when its initial plans for the C-X75 changed from an experimental turbine powertrain to a multi-charged inline-four. Only this time the Leaping Cat marque didn't put it into production at all, save for a few prototypes and movie props – which is a bit of a shame, and then some. Watching Jay speed down memory lane in the supercar that almost never was, we're glad that Jaguar still built the XJ220, and saddened that it never followed up with another groundbreaking supercar today.
