A Formula 1 car doesn’t show up for sale that often, let alone one that was driven by two world champions. Originally introduced in 1991 at the San Marino Grand Prix for the third race of the season, the Benetton B-191 was initially driven that year by Roberto Moreno before it was handed over to none other than Nelson Piquet. The legendary three-time F1 champion managed to take a win at Montreal during the Canadian GP, scoring the car's only victory.

Michael Schumacher, a rookie at that time, also had the opportunity to get behind the wheel of the B-191 later the same season. A year later, the car was upgraded to the B191B specification for the first three races of the season and handed over to Brit Martin Brundle.

It went on to become a museum exhibit after the end of the 1992 season and was fully restored last year. An F1 specialist team was in charge of overhauling the chassis, engine, and the gearbox to make sure the car is now in “excellent running order”. The thorough restoration process guarantees the Benetton B-191 is now in original specification, with the exception of some FIA-mandated safety updates.

Since we’ve mentioned the engine, it’s a Ford Cosworth V8 3.5-litre developing 650 horsepower at an impressive 13,000 rpm, in a car that weighs just 505 kilograms thanks to a carbon composite monocoque chassis.

It’s heading to auction at the Bonhams Spa Classic event set to be organised at the Spa Francorchamps circuit in Belgium on May 21st. According to the auction house, the race-winning Benetton B-191 driven by two F1 champions is estimated to fetch anywhere between €750,000 and €950,000 (around £640,000 to £800,000). That’s certainly a lot of money, but then again, this isn’t an ordinary F1 car.
