The shot was published by Spanish website Motorpasion, though it's not clear how the site obtained the image.
Although we can't be 100 per cent certain that the image above is authentic, the design of the headlights and the air intakes below them marries up almost perfectly with an official teaser photo (below) released by Audi last week. The number plate also looks to fit the bill.
If the leak proves to be accurate, the next-gen R8's styling will be an evolution of the current model's. Aside from squarer, sharper details compared to the current car, the new R8 splits the model's signature contrasting side blades into two parts.
So far, Audi has confirmed that the second-generation R8 will come with LED headlights as standard. Laser headlights, similar to the ones used on the limited edition R8 LMX, will be an optional extra.
Details about the car's drivetrain have yet to be fully confirmed, but Audi board member Ulrich Hackenberg has confirmed that the 2015 Audi R8 will not be offered with a manual transmission. Like its Lamborghini Huracan sibling, the new R8 is likely to only feature a seven-speed dual-clutch automated transmission.
The new R8 will be available with either an internal combustion engine or an all-electric drivetrain, with the latter likely to have a driving range of 400 kilometres.
The new Audi R8 will make its public debut at next week's Geneva motor show, and is expected to hit Australian showrooms in 2016.
