That might just have been the best episode they've ever done.
A proper petrolheads episode (and also a filmographers/cameramans, seriously it's the most beautifully shot series ever made nowadays).
I've finally come round to liking Hamilton, his enthusiasm for stuff like that is on a true car-lovers level, and the whole Senna bit was trully magnificent. I cannot wait for the film to come out now.
What this episode showed was just how trully big Top Gear has become as well:
Tom Cruise and Cameron Diaz for starters (hats off to both of them for not being unbearable and actually being able to drive).
Then you add all of the F1 drivers, you add Hamilton (probably the biggest star around in F1 circles) driving a car that is usually tucked away in McLaren's headquarters and probably not allowed to be touched by the employees that work there being it's so valuable and mythic.
Finally you add in the Veyron Supersport, a car that was only revealed a few weeks back, and you have Top Gear on hand for the speed records which are usually done behind closed doors, and they managed to get it round the track without any trouble whatsoever, something they couldn't do with the original Veyron 'cause Bugatti wouldn't let them.
