I’ve known Gordon Murray for at least 30 years, and if he’s changed in that time, I’ve not really noticed. Of course if I look back at photographs taken when I first got to know him during the development of the McLaren F1 in the early 1990s, I can tell the hair is greyer, and I guess if I looked closely enough the face would show some evidence of the intervening decades, but as a person with whom to talk he is the same at 75 as he was at 45. Which is an unstoppable powerhouse of information, insight and enthusiasm. The two of us stood alone in a cold, underground car park for two hours while he talked me around his new T.33 supercar. He barely drew breath.
