Audi Prologue concept drives itself to CES with updated powertrain

What's the point in crafting a one-off concept car if it only gets to stand in the spotlight at one show? That's what automakers have been asking themselves recently, and the answer has, generally speaking, been to repaint their show cars, give them a bit of new tech and put them back on center stage. And the latest to do so is Audi, which has given its Prologue concept a new lease on life. The Prologue was originally unveiled at the Los Angeles Auto Show less than two months ago, showing the way forward for the future of Audi design, in an elegant coupe form that looked ready to take on the Mercedes S-Class Coupe. We even got a chance to drive it around the streets of LA, and when we did, we marveled at the concept's advanced infotainment system that caters a range of personal preferences according to who's on board. "It's easy to see how this could even reach for chauffeured, or autonomously driven vehicles" in the future, we said at the time. And it turns out Audi was on the same page. At CES this year, Audi has brought back the Prologue concept, given it a darker coat of grey paint, a grey-tone interior (instead of the previous shades of brown and tan), a fresh set of wheels and equipped it with the autonomous tech the German automaker has been at the forefront of developing. Though other automakers have been fitting their self-driving prototypes with all-electric powertrains, Audi kept the 4.0-liter twin-turbo V8 in place – but fitted it with a hybrid assist to drive output up from an already prodigious 605 horsepower and 516 pound-feet of torque to an even more impressive 677 hp and 701 lb-ft, dropping the 0-62 time down to 3.5 seconds. Now that's the kind of "piloted driving" tech (as Audi calls it) that we can get behind.

Audi celebrates diesel milestone with triple-charged RS5 TDI concept

Diesels are typically slower than their gasoline counterparts, but leave it to Audi to turn that notion on its head. After dominating Le Mans and the international endurance racing scene under diesel power for the better part of a decade, the German automaker toyed with the idea of an oil-burning R8 for the road and ultimately made its first performance crossover a diesel. It's made the letters TDI a battle cry, and now it's yelling even louder with the RS5 TDI concept.
Set to be unveiled in a couple of days at the Leipzig Auto Show to celebrate 25 years of the TDI engine, the concept ditches the gasoline-burning 4.2-liter V8 in the production RS5 in favor of a 3.0-liter V6 twin-turbo-diesel with an electric supercharger added on to combat turbo lag. Output comes in at 385 horsepower and 553 pound-feet of torque, which means that while it has 65 fewer horses than the gasoline model, it packs a staggering 236 lb-ft more torque.
The result of the triple-charged madness is a 0-62 time around four seconds flat, trumping the 4.6 seconds for the road-going model. Top speed, of course, is electronically limited to 155 miles per hour, which is a bit of a shame because we bet it'd be a kick to pass a Porsche on the Autobahn in a diesel, now wouldn't it?

Delphi thrilled with results from autonomous car's cross-country trip

In the first trip across the United States ever made by an autonomous car, engineers from Delphi Automotive were surprised to learn that, in some cases, their vehicle behaved a lot like a human driver. "The car was scared of tractor trailers," said Jeff Owens, the company's chief technology officer. "The car edged to the left just a little bit when it would pass trucks, and that was an interesting observation." Engineers made hundreds of notes throughout the drive, as the autonomous car covered 3,400 miles through 15 states en route to a showcase near the New York Auto Show. Overall, company officials said the car performed better than anticipated in a variety of road and weather conditions. In the course of the cross-country drive, drivers actually controlled the car only for about 50 miles, and those cases were limited to on-and-off ramps and the occasional construction zone where lanes were not marked or only sporadically marked. The purpose of the trip was to glean information on how the autonomous car worked in a real-world environment. Google and others have tested autonomous cars and autonomous features in select real-world environments before, but Delphi's adventure was the first to trek into a test with such varied challenges over a nine-day trip that began near the Golden Gate Bridge on March 22. There are some things the engineers have already learned, like the fact the camera systems had the occasional blip when the sun-angle was low. And there are some things to still be learned, as they pour over three terrabytes worth of data from cameras, radar and lidar sensors in the weeks ahead. "It's going to take us a couple weeks to digest all this," Owens said. "But we had all the data from tests. It was time to put this on the road." Built into an Audi SQ5, the vehicle was striking, if only for the fact it looked like a normal car. Many other autonomous vehicles have quirky sensors atop the roof or other features that make them stand out as experiments. Delphi arranged this one to look as much like a normal car as possible, right down to stowing an army of computers under cargo mats, so the rear contained as much trunk space as the production model. If a fellow motorist didn't know where to look -- or take the time to notice the person in the driver's seat didn't have their hands on the wheel -- there was no reason to suspect this was anything other than a regular car.
