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 4.2-liter V8 to live again in next-gen R8

Fellow auto enthusiasts, it looks like the car gods have smiled upon us. Word is that Audi's stupendous 4.2-liter V8 will once again be available in the next-generation R8. Rumors pegged the trusty 4.2 as a dead engine revving, thanks to Audi's newer 4.0-liter twin-turbocharged V8 found in models like the S6 and S7.
We expected the 4.0-liter to be the go-to engine in the next R8, but according to Car and Driver, there have been some issues cooling the force-induced mill in the mid-engine R8. The issues are so severe, in fact, that the 4.2 is going to be retained in the car's second generation.
It's more than just practical matters like cooling that are keeping the R8 from going turbocharged. C/D reports that even with the current state of forced induction, a turbocharged R8's throttle response and its resultant exhaust note would suffer too much to be feasible.

Audi Q7 E-Tron confirmed?

Rumors out of Australia say we'll be seeing a new variant of the Audi Q7 when the next-generation models bows in a few years. Joining the diesel and gas range will be the second production member of Audi's E-Tron family, which was introduced by the R8 E-Tron, but will actually see production in the form of the A3 E-Tron.
Speaking with Audi's managing director in Australia, Andrew Doyle, Car Advice asked what the future held now that the electrified R8 had effectively been shelved. "I don't see it [R8 E-Tron] as a major thing for us. We'll launch [locally] with A3, followed by Q7..."
The new Q7 will share its platform with the Volkswagen Group's two other large SUVs, the Porsche Cayenne and Volkswagen Touareg. But, as Car Advice is quick to point out, the Porsche and VW variants are slated for arrive next year - the second-generation Q7 won't arrive until 2015. Doyle refused to explain the discrepancy.
