Audi recently refreshed the entire R8 lineup , with exception to the GT version - the most powerful variant. Now, our spy photographers have caught what appears to be a refreshed version of the R8 GT, or possibly even the R8 GT Plus, out testing. The car was caught at the Quattro GmbH engineers’ testing track and it looks meaner than ever.
Why do we think this could be the Plus version ? Well, because it features some updates that clearly indicate this is no normal R8 GT. These features include: a new chin spoiler for added downforce up front; large brake calipers; and what look to be carbon-ceramic, cross-drilled brake rotors. Around back, we find yet another GT Plus tipoff: a huge wing that looks like it is built from carbon fiber.
On top of the GT Plus-like elements, this prototype also features front quarter panel winglets, like we see on the current R8 GT.
Under the hood, the next R8 GT Plus will get a 5.2-liter V-10 engine that produces somewhere between 575 and 600 horsepower.
Updated 06/17/2013: According to the British magazine AutoCar, the revised R8 GT will be unveiled at the Le Mans 24 Hours race set to take place this week-end, June 22-23.
