Charles Leclerc said he “lost the brakes” in the classic Ferrari, leading to his crash at the Monaco Historic Grand Prix.

Leclerc had been on a demonstration run in Niki Lauda’s 1974 Ferrari 312 B3, taking the classic challenger for a spin around the streets of Monte Carlo, though that ended up becoming too literal.

The current Ferrari driver would lose the rear of the 312 B3 as he entered La Rascasse, causing damage to the rear wing upon a heavy whack of the barrier.

After he got going again, Leclerc would come to a stop on the pit straight, where he found ex-Ferrari driver Jacky Ickx, who had been on a demo run in his Ferrari 312 B2 from 1972.
