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 Rolex 24 at Daytona

We came to Daytona Beach, Florida where you can drive on the beach, gun shops outnumber doughnut shops and you can putt-putt and fish for alligators at the same place. But we're not here for any of that - we've made the trip with Audi in order to experience the Rolex 24 at Daytona, the first race in the 2013 Grand-Am season and the only 24-hour race in America.
Three teams are racing four Audi R8 Grand-Am cars - WeatherTech Racing, Rum Bum Racing and APR, which is running two cars. Shown to the world two years ago, the R8 Grand-Am is part of Audi Sport's R8 LMS customer racing program that was commenced in 2008, and ever since 2009 has been nabbing success all over the world: In four years it has taken 154 victories and 17 series titles. That is with less than 100 cars sold to customers throughout the world, and the trophies - either class wins or overall victories - have been gathered from all of the major endurance races except one: Daytona.

Audi changes the guard at Quattro GmbH

Although it may not have the brand recognition that Mercedes-AMG does or BMW's M division, Audi's Quattro GmbH department is responsible for its most exciting products - including the RS line of performance models and the R8 supercar. For the past year and a half, Quattro GmbH has been led by Franciscus van Meel, but soon it will get a new leader.
According to reports, van Meel (46, pictured right) is being reassigned to head up the Audi R&D center in Beijing. In his place, Audi is promoting Heinz Peter Hollwerweger (60, pictured above) to the post. The move is expected to be confirmed in advance of the Geneva Motor Show, at which point we can expect Audi to claim that it was part of a planned rotation. However sources suggest that van Meel's departure came at the behest of R&D boss Ulrich Hackenberg, who was apparently unhappy with how van Meel has been handling development of the next R8 and of the R8 E-Tron project.
Why Hackenberg would have van Meel reassigned to run one of his own R&D centers is beyond us, but Hollerweger is apparently expected to be able to get the job done faster and better. Whether he'll have any major changes in store for the Quattro division and its products is another matter, but we're looking forward to finding out.
