TheBenetton B191 is aFormula One racing car, with which theBenetton team competed in the1991 Formula One season and at the beginning of1992. Designed byJohn Barnard andMike Coughlan, the car made its debut at the1991 San Marino Grand Prix, driven by two Brazilian drivers, three-timeWorld Drivers' ChampionNelson Piquet andRoberto Moreno. The B191 was powered by the FordHBA5 V8 engine in an exclusive deal with Ford, and ran onPirelli tyres. Following theBelgian Grand Prix the team replaced Moreno with German newcomerMichael Schumacher.
Nelson Piquet gave the B191 its only win at the1991 Canadian Grand Prix afterNigel Mansell's leadingWilliams-Renault suffered electrical failure less than half a lap from the finish gifting Piquet the last win of his Formula One career.
The car was pressed into service for the first three races of the1992 season with small upgrades to bodywork and suspension. This car was dubbed theB191B. Schumacher remained with the team whileMartin Brundle replaced the retiring Nelson Piquet in the team's second car.
The B191 was the first Benetton to feature the now standard raised nose first pioneered byTyrrell in1990.
