Subaru Coloni C3B Formula One Car
The “Subaru” engine powered the Coloni chassis during the 1990 season. Like most F1 engines the project was a badged project, the design and manufacture being done by Motori-Moderni and the end result blessed by Subaru who funded the project. For 1990 the Coloni team itself was 51% owned by Subaru and 49% by its founder Enzo Coloni. They fielded only 1 car and it was driven by Belgian Bertrand Gachot.
The car is described in the 1990/1 Autocourse as “Coloni- Revised C3B chassis powered by a flat-12 Motori Moderni-designed Subaru engine, with transverse gearbox from the same company. An over weight and extremely ungainly makeshift machine.”
