2013 Audi RS6 Avant [w/video]

Latest, Greatest Autobahn Bomber Will Not Be Denied - Except To Us
Back in 2008, I was fortunate enough to test the second-generation Audi RS6 Avant in southern France on the supremely well-sorted circuit at Le Castellet, a.k.a. Paul Ricard. I was thrown out there with the 572-horsepower bi-turbo 5.0-liter V10-equipped behemoth behind one of Audi's DTM pros and was convinced in short order that the flaming hippo in my hands was going to get the better of me on one or another of the track's tight esses. I made it out alive and invigorated, of course, but knew that that RS6 Avant was the heaviest that these thunderwagons should ever be allowed to get. At around 4,650 pounds with driver aboard, it was just way more lateral momentum at speed than any pilot needs on a track - or for that matter, on a favorite hot curving road.
Now it's time for the 2013 Audi RS6 Avant to lay us out with a flying scissor kick from the corner ropes. This version of the highway and byway marauder from Quattro GmbH is a decidedly greater piece of work than was the car I drove in 2008. This time, there will only be the Avant body configuration - no RS6 sedan - and, as with the previous generation, North America won't be at the receiving end when deliveries start at the end of July this year.

Notes and notations on the 2014 Rolex 24 at Daytona [w/video]

This year is the 52nd edition of the Daytona 24 Hours. The 2014 Rolex 24 at Daytona is also the first race of the year in the brand new TUDOR United SportsCar Championship (TUSCC) With the merger of the American Le Mans Series and Grand-Am Rolex Sports Car Series rewriting and revising the rules of American sports car racing right up until yesterday, we've made the journey to an intermittently wet and constantly freezing Daytona Beach, Florida with Audi to watch the new R8 LMS and every other competitor explore the limits of those rules on the track.
With a ton to cover - and a couple of videos below to watch, including some slo-mo qualifying footage and a hot lap in an R8 LMS - let's not waste time with chit-chat, eh?
Quick things to know about the classes and the leader-light system:

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.
