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 Champman projects: the Lotus 80, conceived as the ultimate ground effect car but prone to such chronic porpoiosing 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 Lotus and De Angelis only garnering three more top-sixes that season.
The 81 was used for three more rounds the next year until its 91 successor arrived (following the abandonment of the 88), with Mansell clinching his podium at Zolder in its final run out.
