Audi R8 vs Golf 5 R32 HGP Turbo

In this video you will see a Golf 5 R32 HGP Turbo “racing” an Audi R8 in a busy highway.
As the YouTube video description says the golf has 437 bhp and Audi has 419 bhp which it means it has a V8 engine.

This looks more like a game than a real race because R8 driver looks like he is toying the Golf driver or maybe the Golf can really keep up pace.
Watch the video and judge it yourself!
