Jaguar I-Pace EV has a new pedestrian warning sound: Listen to it here

Jaguar's production of its first electric car means it also has to deal with a problem everybody else has been trying to solve: noise, or rather, the lack thereof. People can hear an engine at low speeds when they're walking along a sidewalk. The same can't be said for silent-operating electric cars. We wrote about Chevrolet's latest solution to the noise problem a few weeks back, and now Jaguar is sharing what it came up with for the I-Pace. The noise it didn't use is almost more interesting than the one it did, though. Jag says its first iteration was meant to be spacecraft/UFO inspired, but apparently it was so convincing that people tended to look up at the sky instead of at the road. Engineers switched it to what seems like a pretty general hum sound for production. Take a listen yourself in the video above — you'll hear the noise at the 40-second mark, and a few other spots after that. The sound is emitted from a speaker behind the grille at speeds up to about 12 mph. It'll change in pitch and volume to correspond to the increasing or decreasing speed of the vehicle — it even changes tone when you shift into reverse to signal a change in direction. Jaguar says the noise is no longer needed at speeds above 12 mph because tire and wind noise become sufficient enough at that speed. Chevy turns the noise off on the Volt at about 20 mph, however, showing that manufacturers haven't really come to a consensus on what should be happening. A U.S. law that hasn't gone into effect yet will ask manufacturers to keep the noise at up to 18.6 mph, though. We happen to be partial to the jaguar growl heard right at the end of the video as a warning sound. That's how you make an entrance with a Jaguar. These kinds of systems are necessary to warn those who might be blind or visually impaired, but distracted walkers are a huge demographic of people needing a warning too. Everybody walks around with their head buried in a phone nowadays, making silent vehicles a hazard of our own habits. Jaguar says it specifically engineered the noise so that it doesn't intrude upon the cabin, so only pedestrians are bothered by the hum when slowly plodding through cities.

2016 Jaguar XJ sedan revealed

Jaguar has been steadily updating its sedan lineup, launching the entry-level XE and a new version of the mid-range XF – and now it's revealed an refreshed version of its flagship XJ. A facelifted version of the existing model (which was first launched in 2009 and arrived in the US in 2011), the 2016 Jaguar XJ benefits from a few key enhancements to keep it current. The principal visual updates revolve around the exterior lighting, which now includes full LED headlights, new daytime running lights and redesigned LED tail lights. There are new oval exhaust tips as well, but some of the most vital updates have been carried out inside. The refreshed interior includes a new InControl Touch Pro touchscreen infotainment system, with multi-touch control and backed up by a 60-gig solid-state hard drive. A new 17-speaker Meridian sound system comes standard, and the instrument cluster has been redesigned as well. The XJ also benefits from Jaguar's All-Surface Progress Control system and a raft of driver assistance features. Rear-drive models also get a new electric power-assisted steering rack and semi-automated parking system. Between engine options, drivetrain choices, wheelbase lengths, and trim levels, the updated XJ continues to offer an array of configurations – and Jaguar has worked to further differentiate them from one another. The base model carries the 340-horsepower, 3.0-liter, supercharged V6 and can be specified with rear- or all-wheel drive. There are regular and long wheelbase versions, and in R-Sport and Portfolio trim lines (the former now coming standard in the shorter car). Though the entire range is supercharged, the model designated as the XJ Supercharged packs a 470-hp version of the company's celebrated 5.0-liter force-fed V8, while the performance flagship XJR packs the same engine but with 550 hp (once again in either wheelbase) and now comes standard with the Black Pack. The 2016 Jaguar XJ is slated to reach US showrooms this fall. The updates will surely go a long way towards keeping Coventry's flagship sedan in the game for longer until an all-new model is ready. The question is whether these updates will be enough to keep the XJ competitive against the newer BMW 7 Series, Mercedes S-Class, and Maserati Quattroporte. Or for that matter with the Audi A8 that's just as old but was also recently refreshed, or the Lexus LS that's been around for longer with similar updates along the way.

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.
