1994 saw a rare dip in performance for Newey-designed cars and the team and drivers struggled to match the Rory Byrne-designed Benetton B194 for pace and reliability. Disaster struck at the 1994 San Marino Grand Prix with the death of Ayrton Senna who had joined Williams that year. A late-season charge, helped by a two-race ban for Schumacher, enabled Williams to claim their third straight constructors' championship. However, Williams were unable to take a third consecutive drivers' title, and with possible manslaughter charges for Senna's accident in prospect, cracks began to show in Newey's relationship with Williams team management.
