Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.

Audi reveals driver lineup and livery for Rolex 24 at Daytona

Audi has announced driver lineups for its customer teams running the R8 LMS GTD in this year's Rolex 24 at Daytona. The Rolex 24 is the first event for the inaugural season of the new United SportsCar Championship series, which merges the old Grand-Am Series with the American Le Mans Series. The new series kicks off January 25.
Flying Lizard Motorsports, which has traditionally been known for repping the Porsche 911, will campaign a pair of R8 coupes, while GMG Racing, Paul Miller Racing and Fall-Line Motorsports will run one car each. A number of drivers on each team are Audi Sport factory drivers, hot shoes like Oliver Jarvis for Fall-Line and Filipe Albuquerque and Dion von Moltke for Flying Lizard, while there are also a few Audi Sport customer drivers.
"We have a fantastic group of racing partners and drivers this season and look forward to defending last year's Daytona win," said president of Audi of America, Scott Keogh. "The successes of the R8 in endurance racing are a testament to the engineering found in every Audi on the road today."

Audi prepping minor refresh for S6

Audi is well underway with testing for all of the refreshed versions of its A6-based sedan. We've already shown you shots of the Euro-spec A6 Allroad (which will wear some of its styling with our US-spec A6 sedan), and now we have some shots of a car that will actually arrive in the United States - the S6.
Like the Allroad, this will be quite a modest refresh, with tweaks to the headlights and taillights, as well as some slightly revised front and rear fascias. The headlights should get a new LED DRL pattern, although we doubt the changes will be much more drastic than that.
As with the Allroad, it seems likely that Audi will make a few very small changes to the interior, while the MMI infotainment system should also see an update. Changes under the hood, though, are more difficult to guess. That said, minor changes could be in store, but don't expect a dramatic increase in power or performance.
