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.

Audi and Porsche squabble over future product platforms

In the buildup to the 2014 24 Hours of Le Mans, Audi delivered an amusing video that worked on the playful rivalry between the German brand and its favorite frenemy, Porsche. We called it sibling rivalry, and at the time, it may have been just that. But just like sibling rivalries, it's all fun and games until someone gets hurt, and that's just what seems to be about to happen in the formerly peaceful Volkswagen Group family.
A new report from Automobile calls out the growing animosity between Porsche, who is backed up by Bentley, and Audi, whose primary ally is Lamborghini. No blows have actually been thrown, although there is a fair amount of "he said, she said" going on.
As Porsche tells it, for example, the new global fullsize SUV architecture being developed by Audi isn't up to snuff, citing size and structure issues, as well as an inability to accommodate a wide variety of engines.
