EKS has released a new video which features Mattias Ekström and Walter Röhrl.

In the clip, Röhrl gets behind the wheel of the Audi S1 EKS RX quattro and puts in a lap at the Estering circuit in Germany. He comes away pretty impressed as he notes the "unbelievable" power that is produced by the car's turbocharged 2.0-liter four-cylinder engine that develops 560 PS (412 kW).

While the video doesn't reveal who drove faster, Ekström notes it was a true pleasure seeing Röhrl in action and he was really impressive that the legendary racer did some corners better than he did.
