The Benetton B191 is a Formula One racing car, with which the Benetton team competed in the 1991 Formula One season and at the beginning of 1992. Designed by John Barnard and Mike Coughlan, the car made its debut at the 1991 San Marino Grand Prix, driven by three-time World Drivers' Champion Nelson Piquet and Roberto Moreno. The B191 was powered by the Ford HBA5 V8 engine in an exclusive deal with Ford, and ran on Pirelli tyres. Following the Belgian Grand Prix the team replaced Moreno with German newcomer Michael Schumacher.
