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.

Bosch fuel pumps spark recall of 2015 Golf, GTI and Audi A3

A few weeks ago, BMW and Nissan both issued recalls for some of their vehicles to replace Bosch-supplied fuel pumps. The pumps had nickel plating that could flake off and cause a failure. Volkswagen Group is the latest automaker to be affected by the problem and has a campaign for the 2015 Audi A3, VW Golf and GTI. In total, 6,204 units of these models are in need of repair. The problem with the VW Group vehicles is identical to the previous recalls. It's possible for the pump's nickel plating to come off and cause increased friction. Eventually, this can result in the component's failure. According to documents from the National Highway Traffic Safety Administration (as a PDF, here), there are no reports of accidents or injuries from this issue in the VW Group models. Bosch spokesperson Linda Beckmeyer tells Autoblog that these vehicles don't all necessary share an identical fuel pump, but the parts all use the same plating process. The problem also prompted repairs of the 2014 Ford Escape several months ago, she indicated. When asked if the issue could prompt more campaigns, Beckmeyer said that she "can't speak to that" because automakers decide on the recalls. Owners should receive notice of the problem soon, but according to the NHTSA documentation, there currently aren't enough pumps to fix all of these vehicles. "Bosch is working closely with automakers regarding replacement parts," Beckmeyer said. When available, dealers will replace the components free of charge for affected customers.

CONSEQUENCE: If the fuel pump fails, the vehicle will not start, or if the engine is running, it will stop and the vehicle will stall, increasing the risk of a crash. REMEDY: Volkswagen will notify owners, and dealers will inspect the vehicles and replace any affected fuel pumps, free of charge.

Audi TT Ultra Quattro Concept throws lightness at the problem

Audi is celebrating the 2013 Wörthersee Tour with a special concept version of the company's TT. The Audi TT Ultra Quattro concept tips the scales at just 2,449 pounds thanks to some extensive engineering work. The company pulled nearly 95 lbs from the car's body structure and used carbon-fiber reinforced plastics for many of its detachable body components. As a result, the concept weighs in at a full 220 pounds lighter than its production counterpart. Throw in a wicked turbocharged 2.0-liter four-cylinder engine with 310 horsepower and 295 pound-feet of torque, and you get a machine with the power to weight ratio in the supercar realm. 0-60 comes up in 4.2 seconds and top speed is listed at 173 mph.
Inside, the TT Ultra Quattro features plenty of carbon fiber trim, and designers also fitted the seats from the R8 GT to save a little weight. The buckets use CFRP for the seat frames, saving nearly 50 pounds in the process. In a world where automakers seem blind to the negative effect of throwing more heft at a vehicle, we're in love with the Ultra Quattro concept.
