Audi SQ7 coming, will have electric turbo

Formula 1 and endurance racing are already harvesting energy from turbos on the track, and now it's apparently time for a similar idea of boosting the efficiency of forced induction to hit the streets in a high-performance, diesel SUV.
In a recent interview with the UK's Autocar, Audi technical boss Dr. Ulrich Hackenberg let the big news slip. "The new Q7 will be available in the market next year but the electric turbo will come a bit later in the Audi SQ7 available in 2016," he said. The e-turbo system was already rumored for the premium SUV but for the standard model, not this just-announced performance version.
Audi has been experimenting with the e-turbo system for a little while, as an electrically driven supercharger. It showed up on the RS5 TDI concept that used a 3.0-liter, twin-turbocharged diesel V6 plus the electric system to diminish turbo lag. In that application, it provided an impressive 385 horsepower and 553 pound-feet of torque and an alleged sprint to 62 miles per hour in 4 seconds. Although, Dr. Hackenberg didn't make it clear if this was the exact layout for the SQ7.

Audi execs mulling turbocharged, entry-level R8

The just-launched, second-generation Audi R8 is apparently a pretty fantastic example of Vorsprung durch Technik. While it's sublime to drive, Audi might already be missing some potential sales due to the lack of an true entry-level version in the supercar's lineup. Lending further credence to an earlier rumor about just such a model, company execs are saying to expect an entry-level, turbocharged R8 to launch in the coming years. "It is inevitable that we will go to a turbocharged motor for it at some point," Audi technical development board member Dr. Ulrich Hackenberg said to Motoring. "It would be in this model cycle, to give us a fuller range." The executive certainly isn't mincing words about forced induction, but the V10's position in the lineup is also secure. "It doesn't mean we are not going to do a turbo, but naturally aspirated is here to stay as well," he said. If Dr. Hackenberg's direct assertion isn't enough, Quattro GmbH chief Heinz Peter Hollerweger further clarified to Motoring that the turbocharged engine would slot into the bottom of the R8's range. An unnamed "senior sales and marketing source" within the Audi also said that the company's turbo five-cylinder was among the currently favored choices for the application. The first rumors about the R8 getting a forced induction version arose just a few months ago. At the time, Audi's electrically turbocharged, 2.5-liter inline five-cylinder was considered an option. The model would solve a problem in markets, like China, that severely tax big displacement engines. Customers might not even need to worry about giving up too much performance either. In the Audi TT Clubsport Turbo concept, the powerplant has a total output of 600 horsepower and 479 pound-feet of torque. While 10 fewer ponies than the latest R8 V10 Plus, it would bring 66 lb-ft more twist to the supercar.

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.
