In 1955 a 25-year-old Stirling Moss, and his navigator Denis Jenkinson, drove the Mille Miglia in 10 hours, 7 minutes and 48 seconds, an average of 97.9 miles an hour over a 992-mile, open-road course. It's a record that still stands to this day.
True, the Mille Miglia ceased to exist as a road race after 1957 due to two fatal crashes along the route, but to pilot a 50s-era car for over ten hours at speeds up to 150 mph on country roads is an astounding feat few drivers can match. As Stirling says in the video, most of the competition ended up crashed out on the side of the road within the first 20 kilometers.
The car they drove was the Mercedes-Benz 300 SLR, the slippery, 310 hp, straight-8 coupe, seen in the fantastic Petrolicious video above.
