Kobayashi tested Ferrari F1 car at Fiorano 28 May, 2013 Kamui Kobayashi during the Monaco GP weekend Sidelined F1 driver Kamui Kobayashi has tested a Ferrari Formula 1 car at the Italian team’s Fiorano circuit. Some immediately interpreted the news as a sign the Maranello based squad might be shaping up a potential replacement for Felipe Massa, who went to hospital for checks after two high speed crashes in Monaco at the weekend. In fact, the former Toyota and Sauber driver – who is now under contract as a Ferrari sports car driver – was simply trying Ferrari’s 2010 car ahead of a forthcoming demonstration event scheduled for Russia. “I raced against this car and I knew how quick it was, so it was very important to get some experience of it,” the Japanese driver said.
