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.

Next-gen Audi Q7 to debut in Detroit

Audi's public relations team must really be getting fed up with research and design boss Ulrich Hackenberg. Aside from basically confirming that the next Audi R8 will share its bones with the Lamborghini Huracán and noting that it may take advantage of the Asterion Concept's hybrid powertrain technology, he's now let slip that the second-generation Q7 will arrive in January at the 2015 Detroit Auto Show.
"If you make a trip to Detroit, you'll see it," Hackenberg reportedly told Indian Autos Blog during Paris Motor Show festivities.
That's a bombshell, particularly as we've heard plenty about its potential powertrain technologies, including spy shots of diesel-powered models, plug-in-hybrids, sporty SQ7s and electric turbochargers, but there's been absolutely nothing concrete about when and where the car would debut.

Did the new Audi R8 just get outed on Instagram?

While we can't confirm it officially, what you're looking at above, according to Instagram user dreboog (Dre Boogie), may indeed be the next Audi R8. We're expecting Audi's revised supercar to get its official debut at the 2015 Geneva Motor Show, which would makes the timing of this leak make sense. You can compare this image with the spy shots we've already seen and draw your own conclusions, but it looks about right to our eyes. There are a few interesting tidbits worth noting, the most immediately obvious being the lack of the so-called side blades that were a polarizing styling element with the first Audi R8 first hit the scene but which have since become part of the coupe's signature look. We also see a front fascia that brings the low-slung coupe more in line with the German brand's current design ethos. Besides those readily apparent cues, there's not much to glean from this Instagram leak. We'd certainly expect more power from Audi's halo car, but just how much more than the 430 horsepower offered by the current V8, 525 hp from the V10 or 550 hp from the V10 Plus, we look forward to finding out. In the meantime, feel free to let us know what you think in the Comments.
