The Leyton House CG901 was a Formula One racing car designed by Adrian Newey for the 1990 Formula One World Championship. Five chassis were built and were powered by the Judd EV 3.5 litre V8 engine. Chassis 001 was subsequently modified mid-season to accommodate the Ilmor 2175A engine the team used in 1991. The drivers for 1990 were the highly rated Ivan Capelli and Maurício Gugelmin. The CG in the name stood for Cesare Gariboldi, a March Leyton team manager who was killed in a road accident in 1989.

The CG901 appeared in two distinct specifications, the early season A spec and the mid to late season B spec. The change was largely an aerodynamic update to correct design errors incurred as a result of erroneous data from the team's wind tunnel. The basis for the car was an evolution of the CG891 of 1989 but with even less compromise from an aerodynamic stand point. This approach caused the car to be extremely sensitive to pitch and roll necessitating a very stiff set-up.

The "tub" is a monocoque type of carbon fibre construction encapsulating the driver, front suspension dampers and fuel cell. The cockpit area was reputed to be very small and cramped, in fact on the lower portion of the tub two external blisters are visible to allow the driver's heels to fit into the narrow space. The dampers were located in front of the driver's feet and were of 2 way adjustable Koni type. The dampers were actuated via rockers by pushrods from the front uprights. The detachable nose section incorporates the front wing which was bolted from the underside and sat proud of the nose itself.
