The Pass

Barry — 58 · Watching since Senna

Nigel Mansell's 1992 Williams FW14B was the most dominant car I ever saw. Active suspension, traction control, electronic differentials — things I didn't understand and didn't trust. And Ayrton Senna, in an older car with less downforce and less power, drove it into a ditch. Not literally. But that's what the pass on the pit straight did to everything Mansell had built that season.

The move itself: Mansell draws alongside on the straight. They're going into a right-hander. Senna brakes later than is sensible, later than I'd have called possible. He goes under, Mansell's out of position, and that's the race. I've watched that moment maybe two hundred times. I still flinch at how late the braking point was.

The data from the onboards: Mansell's braking point for that corner was approximately 95 metres before the apex. Senna braked at 68 metres. Twenty-seven metres later than the fastest driver in the fastest car chose to brake — and he made it stick. The traction model I use would have given that move a 43% success probability. Senna apparently calculated differently.

For context: the FW14B had 42% more aerodynamic downforce than the McLaren MP4/7. On pure pace, Senna winning that race was a 7% probability event. He treated 7% probabilities like certainties, and that's why no number I put on him ever fully captured what he was. The model is embarrassed. The model remains embarrassed.

The FW14B's active suspension meant it was always at optimal ride height regardless of fuel load, kerbs, or driver input. That's a massive advantage in theory. But active suspension is only as good as the software mapping, and the software couldn't account for a driver who committed to a late-apex line that no dataset had mapped. Senna literally went off the model.

What I find technically remarkable is what Senna did before the overtake. He spent three laps positioning himself on the exit of the final chicane to compromise Mansell's exit speed — deliberately using the McLaren's chassis balance to be narrow through the apex, forcing Mansell wide. The overtake started three corners before the overtake. That's what separates the truly great from the merely exceptional.
