Designed by John Barnard and Mike Coughlan, the car made its debut at the 1991 San Marino Grand Prix, driven by two Brazilian drivers, three-time World Drivers' Champion Nelson Piquet and Roberto Moreno.

History

Nelson Piquet gave the B191 its only win at the 1991 Canadian Grand Prix after Nigel Mansell's leading Williams-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 the 1992 season with small upgrades to bodywork and suspension. This car was dubbed the B191B. Schumacher remained with the team while Martin 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 by Tyrrell in 1990.

The B191B was replaced by the Benetton B192 following the 1992 Brazilian Grand Prix.
