Leonard E. Terry (11 February 1924 – 25 August 2014)[1][2] was an English racing car designer and engineer, known for his work with Lotus, BRM and Eagle.

[2] After completing military service, Terry trained as a draughtsman[3] and this led to him being employed by a contract design company who seconded him to Aston Martin, where he worked on the DB2/4.

[3] His Terrier sports car was not successful, but he teamed up with future Formula One engine builder, Brian Hart for the MkII version.

[3] At this time, Terry also supplied drawings for the Moorland Special which was purchased by the Gemini team and formed the basis of their Mk1 Formula Junior car.

Even though the car was tested by Bruce McLaren it was not raced by a top-line driver and the project ended when Gilby was taken over by a firm which was not involved in motorsport.

He was working on a freelance basis (including for Lotus) when Colin Chapman asked him to return full-time to design a car to compete in the Indianapolis 500.

[5] For the 1965 Indianapolis 500, Terry was given full control over the design of the Lotus 38, and the car finished first that year, and second in 1966, each time with Clark driving.

[3] Len Terry was commissioned to design and build a lightweight full spaceframe Ford Escort Mk1 Special Saloon for Geoff Wood, this was chassis number 40.

Terry's next design was a Formula 5000 car; intended as a privateer project it was taken up by Surtees and used by David Hobbs to finish second in the 1969 US Championship.
