The 81 made its debut during the 1980 season, and what stands out about this car is that, from a Lotus design perspective, it isn’t that remarkable.
The car was built as a stopgap between two other disastrous Chapman projects: the Lotus 80, conceived as the ultimate ground effect car but prone to such chronic porpoising it was rendered unusable, and the beleaguered twin-chassis 88, which caused such uproar amongst other teams over its legality that it never even made a GP start.
The 81 was the bog-standard rule-pleaser that Lotus used in the meantime, but it still holds a significant place in Hethel history.
Initially wheeled out for Andretti and De Angelis for 1980, the latter gave the car its best result in just its second race with a runner-up spot at that Brazilian GP.

Unfortunately the car was unreliable, with Andretti scoring just a single point with it before departing for Alfa Romeo the following year and De Angelis only garnering three more top-sixes that season.
