Lotus drivers in GPL:

The original GPL has Lotus as a two car/two driver team (Clark and Hill), which reflects the majority of the season.

The third driver joining the team towards the end of the season was usually a local.

Lotus cars in GPL:

The team began the season with the Lotus-BRM 43, their 1966 season car, powered by BRM's 3 litre H16 engine. This car can be downloaded from GPLEA.

The lighter Lotus-BRM 33 (2.1 litre V8) and Lotus-Climax 33 (2.0 litre V8), also from the 1966 season, were used at Monaco.

They were replaced by the Lotus-Ford 49 from Zandvoort on, powered by the Cosworth 3-litre V8 engine.

The Lotus modelled in GPL physics is the Lotus 49.
