Watching the Indy Racing League from Watkins Glen, where Formula One raced until 1980, got me wondering how three of the top international single seater series compared with one another when using the same circuits. I compared best lap times from the 2005 F1 and Champ Car seasons, and 2005-06 A1 Grand Prix season.
No surprise that F1 was way ahead – 7.3s quicker than Champ Cars over a lap of Montreal, and around 20s per lap quicker than A1 at the longer circuits of Shanghai and Sepang. What surprised me was how much slower A1 is than Champ Car, which is surely the kind of performance standard it should be aiming for?
