Ultra-rare Ayrton Senna 1994 F1 Williams set for multi-million pound auction

A 1994 Williams F1 car driven by Ayrton Senna is to be auctioned next month - one of just two surviving FW16s the Brazilian drove.

FW16 chassis 01 was driven by Senna during pre-season testing and during the morning warm-up ahead of the 1994 Brazilian GP before he reverted to a different chassis for the race.
