The making of the Williams Renault FW15c, Alain Prost’s last championship winning car

Taken from In the early nineties Williams bounced back in great style after several difficult seasons. Essential in this return to form were an engine deal with Renault and the arrival of hugely talented designer Adrian Newey. The Renault V10 had already powered the British team to a pair of wins in both 1989 and 1990 but it was not until the Newey designed FW14 arrived in 1991 that Williams was able to challenge the dominant McLaren team. Newey’s very efficient aerodynamics and the powerful engine had resulted in seven wins and a second place in the constructor’s table in 1991. If it wasn’t for reliability issues early in the year the team would have been in contention for both titles. Much of the development work for 1992 focused on sophisticated electronics. Awaiting the completion of the new FW15, the new bits were fitted on the interim ’FW14B’. This proved so dominant that there was no need to roll out the FW15 in 1992. Adapted to min
