The Lotus 109 was a Formula One car used by Team Lotus in the latter part of the 1994 Formula One season. This was the last car to be run by the original incarnation of Team Lotus, and was based on the Lotus 107C model.
Johnny Herbert was able to keep Lotus competitive in Belgium and Monza with the car, but funds were drying up and development was limited. At the end of the season, the car was retired and Team Lotus went into receivership.
