Audi R8 spyder appears headed for Frankfurt show

The much-anticipated Audi R8 spyder likely will make its world debut in production guise at the Frankfurt motor show in September.

The drop-top version of the head-turning German supercar would share mechanicals with the coupe, which offers a V8 making 420 hp and a V10 with 525 hp. The R8 has a mid-engine layout and channels power to the ground with all-wheel drive.

The R8 convertible would be a 2011 model. Officially, Audi is mum, but the car has been caught in spy shots and it appears likely that the company would want to make a splash at Frankfurt. It
