His second stint with Williams was even better than the first. Back in the familiar 'Red 5', he won five races in , including the Spanish Grand Prix. In this race he went wheel-to-wheel with Ayrton Senna, with only centimetres to spare, at over on the main straight. Quite a different spectacle was offered following Mansell's victory in the British Grand Prix at Silverstone. Senna's car had stopped on the final lap, but, rather than leave his rival stranded out on the circuit (the two had come to blows in the pits following their first lap tangle during the 1987 Belgian Grand Prix and were hardly close friends), Mansell pulled over on his victory lap and allowed Senna to ride on the Williams sidepod back to the pits.
