The Simtek S941 is a Formula One car, designed by Nick Wirth and Paul Crooks for the Simtek team, and used during 1994 Formula One season. Although it was the first car to race under the Simtek name the company had previously designed an unbuilt car for BMW - the unbuilt design formed the basis of the Andrea Moda S921. Simtek also produced a design for Jean Mosnier's abortive Bravo S931 project which was to have launched in 1993. There is a strong family resemblance between the 1992 Andrea Moda and the 1994 Simtek.

Simtek was an engineering consultancy firm and Formula One racing team. The Formula One (F1) engineering consultancy arm, Simtek Research, was founded in 1989 by Max Mosley and Nick Wirth. It originally was involved in many areas of Formula One, including wind tunnel construction and chassis building for third parties. Simtek Grand Prix, the racing team, was launched in 1993 and competed in the 1994 and 1995 seasons, achieving a best result of ninth place. With large debts and a lack of sponsorship money, Simtek went into voluntary liquidation in June 1995.
