Motori Moderni
The initial design of the CC was penned down by Christian von Koenigsegg. Industrial designer David Crafoord realised the sketches as a 1:5 scale model. This model was later scaled up in order to create the base plug for the initial Koenigsegg prototype that was finished in 1996. During the next years, the prototype went through extensive testing and several new prototypes were built. The prototypes initially used an Audi V8 engine but after the engine supply contract fell through, the next candidate was the Flat-12 race engine developed by Motori Moderni for the Scuderia Coloni Formula one team, in which this engine was raced under the Subaru badge in the 1990 season. These Subaru 1235 engines were purchased and modified for use in the CC; this deal failed when the founder of Motori Moderni died, sending the company into bankruptcy. Eventually Koenigsegg developed its own engine based on the Ford Modular architecture which was used in its early sports cars. Later on, Koenigsegg developed their own engines from scratch, including control systems and transmissions, which is very unusual for a small size sports car producer.
