Welcome to the first installment of Rad Racing Video Of The Week, where I feature a epic racing video that I found while browsing YouTube. The Sauber C9 and C11 are the most brutal prototype racers ever, with twin-turbo V8’s making 700+ horsepower and top speeds over 240 miles an hour. This absolutely badass onboard from Spa in 2011 shows the skill needed to drive it flat out.
