Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

2016 Audi TTS Roadster opens up for all to see

The five-door Sportback concept may be garnering the lion's share of attention as far as the TT goes, but that's just for show. The more tangible news from Audi's stylish sports car range at the
this year is the Roadster.
Like its predecessors, the new Audi TT Roadster ditches the coupe's fixed roof and rear seats in favor of an open two-seat cockpit with a traditional folding fabric enclosure that's quieter and lighter than the previous TT's mechanism.

Audi promises next A8 on sale by year's end, LED Matrix lamps to be available [w/video]

Audi has just released details about its new Matrix LED headlamps, but just as illuminating as the new lighting technology is confirmation that the next A8 will appear "on the market at the end of 2013." While Audi is calling the model new, expectations - and the spy shots above - suggest more of a traditional mid-cycle refresh.
Audi says that its new A8 Matrix lights are comprised of 25 high-beam LEDs, clustered in groups of five paired with reflectors. Unlike traditional automatic high-beam setups, the Matrix array is so precise that it "blanks out light that would shine directly onto oncoming and preceding vehicles" while continuing to use full high-beam power on other sections of the road and shoulder not occupied by other vehicles. Further, the camera- and electronic brain-governed system can dim or extinguish LEDs as necessary to deal with traffic. The active system also differs from today's adaptive headlamps by not requiring servo motors to direct light, yet they can still function as cornering headlamps - ones that can predict a road's trajectory because they are linked with the car's GPS system. Interestingly, the system also works with Audi's optional night vision system. When the latter detects a pedestrian in the dark, it automatically flashes a batch of LEDs to put both the driver and pedestrian on notice about each others' presence.
Only one problem in all of this trick lighting business: they aren't legal here in the US, at least not yet. Audi and other automakers are currently petitioning the National Highway Traffic Safety Administration, trying to sell the government agency on the technology's safety benefits. For the moment, Matrix headlamps are likely to remain forbidden fruit, but you can check them out and see what you might be missing in the video below. As for the 2015 A8, we're guessing it'll surface at the Frankfurt Motor Show in September.
