Initially sponsor of the Toleman team, Benetton took over the team at the end of 1985 and from 1986 entered the F1 championship under its own name. The 1986 Benetton B186 had almost nothing in common with the 1985 Toleman. From the Hart engine the team moved on to the BMW M12 / 13 and the chassis design was also completely new. Due to the delay with which the whole operation was finalized, the car was developed in parallel to the race preparation. Nonetheless, the B186 proved to be quite competitive, allowing Berger to win in Mexico. The other 1986 Benetton driver was Teo Fabi.
