World record with a Silver Arrow at Mille Miglia.

At the 1955 Mille Miglia, the young British racing driver Stirling Moss and his co-driver Denis Jenkinson piloting a Mercedes-Benz 300 SLR (W 196 S) with starting number 722 come in first with the average speed of 157.65 km/h in a record time of 10:7:48 hours. This record still holds today. The W 196 S wins every single race the Mercedes-Benz 300 SLR enters and finishes. Moss also wins the Targa Florio (Sicily/Italy).
