The Lambo 291 was a Formula One car designed by Mauro Forghieri for use by the Modena team during the 1991 Formula One season. Its best finish was at the United States Grand Prix when Nicola Larini drove it to seventh place. Forghieri managed to get a car ready by the end of 1990, after which it was tested at Imola by Mauro Baldi. It appeared in a distinctive dark blue livery, featuring triangular side pods and slanted radiators. Apart from those two highlights, the team did not come close to points and usually failed to get through pre-qualifying.
