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.

VW Group exploring F1 options, would likely wait until Ecclestone is out

The real hurdle is that Volkswagen overlord Ferdinand Piech doesn't like Bernie Ecclestone on a personal or professional level. Superbugs. They are antiobiotic-resistant bacteria and viruses, fiends that defy eradication no matter how much counteracting agent you throw at them. Reports that Audi is going to join Formula One? They are the superbugs of rumors; for five years they've been coursing through the blood of motorsport, and no amount of denials or Audi's continued non-presence in F1 has been able to make them go away. Not even a month ago we contracted another bout of it, courtesy of Auto Express, citing sources who said Audi would leave endurance racing and DTM - handing Le Mans over to Porsche, instead of the other way around - and buy either Red Bull or Toro Rosso for an entry in 2016 with an in-house powerplant. Within 24 hours of that story, Audi Sport sent the tweet, "Audi in F1? There rumors keep appearing with regularity since years. It's pure speculation again this time and without any foundation." Now, few things are impossible in F1, but lining up on the grid in 2016 is not far away from needing to be ready tomorrow, in F1 terms, which is why these announcements come long in advance. Honda, you'll recall, gave us almost two years' notice of its F1 reunion and Porsche gave us three years notice about Le Mans. A brand-new report in the BBC says that Audi is using new hire and ex-Ferrari technical director Stefano Domenicali to lead a feasibility study into an F1 program. According to that story, the real hurdle to the foray, however, is that Volkswagen Group overlord Ferdinand Piech doesn't like F1 boss Bernie Ecclestone on a personal or professional level, so one of them would need to leave his position before Audi could say yes, feasibility be damned. Since we're talking about two men who define professional longevity, that day might not come soon. The BBC story goes on to say that Martin Winterkorn, head of the VW Group management board, would like to see the group in F1, and that if it happened it would be with a "car designed and made in Germany." Ladies and gentlemen, you know where to file this one...

Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.
