The Benetton B191 was a Formula 1 racing car with which the Benetton team took part in the world championship in 1991 and early 1992 . The car was designed by John Barnard . The Benetton B191 made its debut at the San Marino GP and was driven by Nelson Piquet and Roberto Moreno .

Nelson Piquet won the Canadian GP with the Model B191 , it was Piquet's last victory before the end of his Formula 1 career.

The car was given minor modifications to the body and suspension for the first three races of the 1992 season and was called the Benetton B191B . Michael Schumacher , who took over Roberto Moreno's cockpit from the Italian GP , stayed with the team, Martin Brundle replaced the retired Piquet.

Technology and development

The designer John Barnard resigned from Benetton in June 1991. Another well-known Formula 1 man could be found in Gordon Kimball . In July, Tom Walkinshaw , then team principal at Jaguar in Group C , took over 35 percent of the racing team. With the influence of Walkinshaw, Roberto Moreno was replaced by Michael Schumacher from the Italian GP . Schumacher later got a contract for the 1992 season . Nelson Piquet withdrew from Formula 1 and, alongside Schumacher, Martin Brundle was committed. Rory Byrne developed the Benetton B191B .

The car weighed 505 kilograms, had a 210-liter petrol tank and a transverse six-speed gearbox. In 1991 Benetton got free tires from Pirelli , but they did not bring the desired success. For 1992 the team switched to Goodyear . The B191 had a Cosworth HB eight cylinder V engine with a cylinder bank angle of 75 degrees. The engine with aluminum block weighed 135 kilograms and in the version used in 1991 as HB V made around 670 hp at 13,200 revolutions per minute with a displacement of 3494 cm³.

production

A total of seven chassis of the B191 / B191B were built in Enstone (Oxfordshire / GBR) .

Painting and sponsorship

The vehicles were painted in the then traditional Benetton green of the team owner and the yellow of the cigarette brand Camel of the main sponsor RJ Reynolds Tobacco Company , the logo of which could be seen extensively on the engine cover and on the wings. The Japanese Autopolis racetrack advertised itself on the side pods . Various small sponsors, including the Japanese electronics group Sanyo and the equipment manufacturers Mobil 1 and Pirelli , added to the budget of the Benetton team in 1991/92.
