We've already speculated what the 2010 Audi R8 Spyder will look like, but now Auto Motor und Sport has video of the V10 roadster ripping 'round the 'Ring. That scream is coming from a suspected 580 HP 5.0-liter twin-turbo V10 from the Audi RS6. Though if you're not quite up for that much punch, the standard engine will be the familiar 4.2-liter V8. Either way, we're thinking more than a few Lamborghini Gallardo Spyder buyers (like Jeremy Clarkson) are wishing they had just waited for this Audi. Video after the jump.
