It'll be released, they just want to keep it a secret but failing horribly

There aren't any official production specs for it since Audi so far has not made a production version of the car official, but that particular one made 500bhp (up 86hp from the V8) and 738lb-ft of torque (up 421lb-ft from the V8). That diesel is one hell of a tire shredder.

yeah that's really hot. I'm not much of an R8 lover, but I like that.
