It's all too easy to take a glance at Sir Chris Hoy's motor racing career and see it purely as a PR stunt.
All the signs are there. One of the world's largest car manufacturers - Nissan - has successfully rebranded Hoy into a racing driver, through campaigns in British GT and the European Le Mans Series, all with the Japanese firm's logo hanging proudly over him. Marketing genius some would say.
Next up. His biggest challenge yet - the Le Mans 24 Hours. He's due to race in the LMP2 class alongside Michael Munemann and Parth Ghorpade in the Algarve Pro Racing Ligier JS P2-Nissan.
