Maybe it wasn’t fast enough. Or maybe there were not enough customers to make its production profitable. There can be many reasons but there’s only one hard fact: you can’t buy an Audi R8 e-tron.

The sports car has made many appearances at motor shows, a few race tracks have also seen it, and there will soon be another place to see the R8 e-tron: movie theaters. Robert Downey Jr., playing Tony Stark in Iron Man 3 will drive an Audi R8 e-tron. But that’s only logic. Tony Stark was already driving an Audi R8 e-tron in a previous movie.

Iron Man 3 is scheduled to begin May 3rd in the U.S.
