Audi Sport Quattro Concept makes video debut

Audi has stayed quiet about its Sport Quattro Concept since the 700-horsepower, tangerine rocket debuted at the 2013 Frankfurt Motor Show - a followup to Quattro Concept shown at the 2010 Paris Motor Show. Now, Audi has broken the plug-in hybrid out to give thanks to its Facebook fans, which now number over 100,000 strong (103,123 as of this writing).
As impressive as that number is, it does seem a bit strange that Audi USA's Facebook page has netted 7.3 million likes, 73 times what Audi's global page has received. Of course, we're not complaining about seeing the Sport Quattro Concept in action, and neither should you. Take a look below for the entire video.

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.

Notes from Day One of the 2013 Twelve Hours of Sebring

The 61st edition of The 12 Hours of Sebring is on, and Autoblog has come to central Florida with Audi to feast on jumbo boiled peanuts, pickled eggs and the final race for the LMP1 class at the oldest road course in North America. As Audi has been doing for more than a decade now, it's brought its latest endurance race car, the 2013-spec R18 etron quattro, to Sebring to begin testing for Le Mans.
Why the commitment to Sebring? Audi Sport executives have repeatedly called Sebring "punishing," "extremely demanding" and "one of the toughest tracks in the world." It is a 3.47-mile circuit that, in places, feels like it was made from the leftover bits of other circuits. Doing the 12-hour distance in Florida is thought to be a good start on lasting the 24-hour distance in France, and we can't think it a coincidence that Audi has won ten times here in the last 13 years and 11 times in Gaul.
Where there's rhyme - and victory - there is reason. We think we found a few of them on our first day where preparation, technology, fastidious attention to detail and sweat fit right in with swamp cabbage...
