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.

Don't hold your breath for an Audi RS8

There was a time not so long ago when Quattro GmbH produced essentially one model at a time. But that time is behind us. These days it's expanding into a full-fledged performance division to rival Mercedes-AMG and BMW's M department. Quattro GmbH is currently building the Audi RS4 Avant, RS5 coupe and cabrio, RS6 Avant, RS7, RS Q3 and the TT RS coupe and roadster - not to mention the R8. And while it's showing no signs of slowing down, but the latest intel from across the pond suggests we shouldn't count on an RS version of Audi's flagship sedan.
This according to Car and Driver, which spoke to Stephan Reil, the chief engineer at Quattro GmbH. Reil says Audi works on a teutonically rigid performance formula: an RS model has to have 20 to 25 percent more power than the existing S version. Considering that the existing S8 makes 512 horsepower and the RS7 a solid 553, we're not sure Audi really needs anything more powerful. But by Reil's calculations, the RS8 would need to pack between 630 and 655 hp, which would put it well ahead of rivals like the 550-hp Jaguar XJR, the 540-hp BMW Alpina B7, the 523-hp Maserati Quattroporte and even the new 577-hp Mercedes-Benz S63 AMG - and in league only with the even more powerful S65 AMG, which in its outgoing form produced 630 hp.
The question then comes down to whether there are enough customers lining up for the S65 that Audi would want to poach away from Mercedes. Or perhaps more pertinently, whether it might end up just taking customers from the new Bentley Flying Spur, which is already offering 616 horsepower in an even more prestigious, if less performance-focused package. Either way you look at it, Audi is apparently steering clear.

Audi wiring cars with cameras to see how ferret-like creatures tear them apart

In this German-language video, we see a batch of Audi engineers wiring up an A3 Cabriolet with a network of small cameras. The goal? To help identify where and how stone martens - small, ferret-like animals - attack cars. The idea is to observe the animals' behavior around the vehicles, see where they go, what they chew on, and work to develop solutions.
So why go to all this trouble? Cars and trucks are easily the single-most complex consumer good, and they're subject to the widest variety of conditions, regulations and usage cases that one could possibly imagine. They also come with very high consumer expectations for reliability. Thus, it's up to automakers to vet their vehicles for just about every possible scenario and threat - including weasels. And if that means Audi has to go hire Walter Simbeck, animal trainer to the stars, and string up a bunch of GoPros on an A3, well, they're game.
In speaking with Autoblog, Mark Dahncke, senior product manager at Audi of America said it best:
