Justin Bell laps Willow Springs... in the dark... using only night vision

Night vision has made its way into quite a few luxury cars as a night-driving safety feature, but eBay Motors wanted to see if the technology could be used to actually drive the car. Former racer and World's Faster Car Show host Justin Bell grabbed the keys to an Audi A7 and headed to Willow Springs Raceway to find out.
As if driving in the dark of the desert night wasn't hard enough, the car's windshield and side windows were blacked out, so Bell's driving relied completely on the three-inch night vision display located in the gauge cluster. In addition to navigating the track, his producers also threw in a few surprises for Bell on the track. We don't want to spoil too much for you, but based on the speeds exhibited in the video, we don't think 24-hour endurance races will be adding this tech any time soon; that being said, he probably drove the car faster and better than we could have.
Scroll down to watch how Bell does lapping the track using only the car's night vision.

Audi kills off its 420-hp four-cylinder engine project

Audi's supercar-slapping, fire-breathing four-cylinder concept engine will remain just that, with Autoblog confirming that it has been internally killed off. Speaking at the launch of the TT RS, the engineering boss of Audi's Quattro GmbH division, Stephan Reil, said the Volkswagen Group had stopped all development of the 420-horsepower, 2.0-liter four it showed in the 2014 TT Quattro Sport Concept car (above). Despite previous assurances that Quattro had roles for both the EA888-based engine and Audi's wildly charismatic 2.5-liter, five-cylinder motor, post-Dieselgate reality has killed the smaller engine. "The 400-horsepower EA888 engine is dead," Reil said. The EA888 engine was conceived and developed by the same man behind AMG's powerhouse 2.0-liter four. Friedrich Eichler left AMG to become the Volkswagen Group's gasoline engine development go-to guy, and he was confident the 420-hp engine could be turned into a production car quickly, as was then-Audi development boss, Ulrich Hackenberg. It was even suggested that because the EA888 engine family bolted straight into the Volkswagen Group's ubiquitous MQB small-car architecture, the little powerhouse could be cheaply and quickly dropped into any of the company's cars that needed an image boost. Since then, Quattro has elevated the five-cylinder motor, switching it to an all-alloy block with a magnesium oil pan to cut down its weight while boosting its power and torque levels. Where the four-cylinder engine was shown with 420 hp and 332 lb-ft of torque, the production version of the TT RS's new five-cylinder engine totes 400 hp and 354 pound-feet of torque. The smaller engine's proponents claimed a 0-62 mph acceleration figure of just 3.7 seconds for the concept TT that carried it, and it might not be a coincidence that the all-new TT RS claims exactly the same figure. The 2.0-liter motor had a torque peak that arrived at 2,400 rpm and began to taper off at 6,300 rpm, while its power apexed at 6,700 rpm, thanks in part to a turbocharger that could feed it up to 1.8 bar of air. Flip to the TT RS' data and you're looking at more torque at lower revs and a touch less power, but at higher revs. That's not a lot of wriggle room for the concept engine to operate, especially when the perceived value of the five-cylinder engine is higher than the four, and the four's development and production costs would be higher than the five's.

Here's how to follow this weekend's 24 Hours of Le Mans

In the pantheon of motorsports, the 24 Hours of Le Mans stands as one of the great endurance challenges to man and machine. This year's event in France already looks to be one for the ages with Porsche setting record-breaking times in practice and the competition debut of Nissan's front-engine, hybrid racer. Thankfully, there's a massive list of ways to follow this automotive attraction. Reilly Brennan, the Executive Director of the Revs Automotive Research Program at Stanford University, and a friend of Autoblog, has once again assembled a helpful couch-kit to organize many of the options. Unfortunately, the old-school way of just turning on the television might be the most frustrating way to watch Le Mans this year. Fox Sports 1 and 2 are carrying about half the race, but the coverage bounces between them seemingly at random. The broadcast begins on Fox Sports 2 at 8:30 AM Eastern ahead of the 9:00 AM start and lasts there until 12:00 PM. Things don't pick up again until 7:00 PM Eastern on Fox Sports 1 for an hour, and the channels swap back and forth more from there. The Fox Sports Go streaming app offers more, but even it stops showing the race a few times. Thankfully, streaming Le Mans is easy. If you can't dedicate 24-hours on the couch, Radio Le Mans lets you listen to audio commentary anywhere with some of the best announcers in the biz. The Automobile Club de l'Ouest, the governing body for the race, also offers an official video stream in an app for $9.99. For a really low-tech solution, the official Twitter is another choice. Brennan is keeping his list updated with coverage changes. You can also check out and download the spotter's guide (from Nissan) in the gallery above. Enjoy this year's race. If you miss anything, don't worry; expect a full report from Autoblog. In fact, editor-in-chief Mike Austin is attending Le Mans this year, so follow him on Twitter for on-the-fly impressions.
