The Toleman TG181 is a Formula One car that was first used in the 1981 Formula One season. It was also the first car used by Toleman in F1.^[1]

Being heavy and with a relatively underpowered and unreliable engine, a 4-cylinder 1.5 litre turbo by Brian Hart, it was a generally poor performing car, with its drivers, Derek Warwick and Brian Henton, only getting through qualifying once each, with Henton's tenth place at Monza the only finish for the car. Due to its bulk, the team ended up nicknaming it the "General Belgrano"^[2] after the Argentine battleship sunk during the 1982 Falklands War, and the "Flying Pig".

Evolutions of the car, the Toleman TG181B and Toleman TG181C, were used the following year, to slightly better effect.
