Audi RS7 prototype is world's sportiest self-driving car [w/video]

Audi may not be the only automaker out there toying with self-driving automobile technology, but it is arguably the fastest of them. A few years back, it raced unleashed a driverless TTS on the Bonneville Salt Flats, then sent it up Pikes Peak and around Thunderhill. But now it's taking things a step further with the vehicle you see here.
This RS7 Sportback has been fitted with steering, brakes, throttle and transmission hooked up to a computer system that combines GPS, high-frequency radio signals and 3D imaging camera to drive the vehicle autonomously not just in slow-paced, stop-and-go traffic, but around the track at the same pace a professional racing driver would push it: full throttle on the straights, full braking before the corner and 1.1-g of cornering force.
As promised, Audi plans to unleash the self-driving RS7 - which it calls "the sportiest piloted driving car in the world" - at Hockenheim next weekend prior to the DTM season finale, where it is anticipated to pull a 2:10 lap time. The next stage will be to set it lose on the Nürburgring Nordschleife, all 154 turns and 13 miles of it, which ought to pose a heck of a challenge to the engineers from Ingolstadt. In the meantime you can scope it out in the high-res image gallery above and the second teaser video below.

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.

Ward's Automotive Ten Best Engines of 2014 dominated by diesels, turbos

With the Car and Driver Ten Best decided, the North American Car and Truck of the Year finalists announced and Cadillac, Ram and Subaru chalking up wins with Motor Trend, it's fair to say that the automotive awards season is in full swing. The next set of trophies to be handed out will be from Ward's Automotive, which has announced the winners of its 2014 10 Best Engines.
The latest contest was marked by the widespread emergence of diesel power and the continued success of turbocharged engines. There was even an electric motor on this year's list. In fact, only three of the ten winners were naturally aspirated and only two winners returned from last year.
"We weren't looking to throw the bums out, as they might say about an election. We were just really impressed with the flood of new powertrains," said Ward's Automotive Editor-in-Chief Drew Winter. Those new powertrains include the 83-kilowatt electric motor from the Fiat 500e, the 1.0-liter, EcoBoost three-cylinder from the Ford Fiesta and the 2.0-liter turbodiesel from the Chevrolet Cruze.
