Hackenberg says next Audi A4 set for Frankfurt debut

The current Audi A4 is among the oldest vehicles in the brand's lineup. Having debuted back in 2008, it's long overdue for an update, and according to our friends at Indian Autos Blog, that'll happen in roughly six months. IAB spoke to Audi research and design chief Ulrich Hackenberg, who indicated that the fifth-generation A4 will be shown at the 2015 Frankfurt Motor Show in September. The new sedan will be unveiled in "a pre-presentation" before the auto show itself, Hackenberg told IAB, adding that "you'll be happy to see it." Information beyond that, though, remains sparse. Based on our previous spy photos, we expect the new A4 to ride on the Volkswagen Group's modular MLB Evo platform that's been stretched to accommodate a larger wheelbase. The styling, meanwhile, will be more evolutionary, inspired in part by the new TT. Expect more on the next-generation A4 as September approaches. Related Video:

Watch Stanford's self-driving Audi hit the track

Sending a self-driving race car around a track with nobody inside seems pointless – there's no driver to enjoy the ride, and the car certainly isn't getting a thrill out of it. But the students performing research with Stanford University's Audi TTS test rig "Shelley" (not to be confused with Audi's own self-driving race cars) are getting a kick out of the numbers generated by the machine. "A race car driver can use all of a car's functionality to drive fast," says Stanford Professor Chris Gerdes. "We want to access that same functionality to make driving safer." The teams push the car to speeds over 120mph and the computers have executed lap times nearly as fast as professional drivers. However, they also spend a lot of time maneuvering at 50 to 75 mph, the speeds where accidents are most likely to happen. That way, the students can figure out how to incorporate braking, throttle and maneuvering to develop new types of automatic collision avoidance algorithms. Better technology, for instance, could have saved Google from a recent slow-speed accident where its vehicle was struck by a bus. During race days, students break into teams to perform different types of research. "Once you get to the track, things can go differently than you expect. So it's an excellent lesson of advanced planning," says Gerdes. In the latest rounds of testing, for instance, one PhD student developed emergency lane-change algorithms, while another recorded a skilled human driver in an attempt to convert his behavior into a driving algorithm. The main goal, of course, is to prepare students for something they may not have expected -- an automotive industry that is adopting self-driving technology at breakneck speeds.

Audi's Q8 Sport concept packs an electric supercharger

Audi's Q8 Sport concept doesn't wear S or RS badges, but it does have impressive performance that would qualify it for one of those monikers. Beneath the tangerine skin, Audi says there is a hybrid V6 displacing 3.0 liters, which isn't particularly interesting, but the forced induction system is. Rather than a conventional turbo or belt-driven supercharger, the V6 uses an electrically-powered supercharger. Audi doesn't provide any details on what kind of compressor it is, but it says the total output of the engine and motor combo is 476 horsepower and 516 lb-ft of torque. This is apparently good for a 4.7-second sprint to 62 mph. This also isn't the first time Audi has implemented an electric supercharger, having used it before on the SQ7 TDI. That orange shell also has updates to show that this Q8 Sport is the fast one. Most of the brushed aluminum trim of the normal Q8 concept has been swapped for gloss black versions. The regular Q8's grille with its chrome vertical bars is also gone in favor of a black honeycomb piece. The fenders have all been stretched by half an inch, and the exhaust tips are now large ovals that protrude from the rear bumper. Audi still hasn't said anything about when a production Q8 will reach the market. However, there's clearly one coming soon, as we've spotted prototypes running around that look similar to the concepts. Related Video:
