The Coloni C4 was a Formula 1 racing car of the Italian team Coloni, which was reported in 1991 to 15 Grand Prix. He was the least successful car of the year because it participated in any races due to regular non- qualifications. 1992 reported him to the team Andrea Moda Formula under the name Coloni C4B for two races; but this year there is no race participation was reached.
The technique
The Coloni C4 was an evolution of 1989 designed by Christian Vanderpleyn Coloni C3. It was based on the 1990 model used temporarily C3C and took over the chassis and suspension components. The body of the vehicle was similar to that of the C3C strong; individual details such as the shape of the side boxes and the air inlet above the driver's head but had been slightly revised. Since Coloni for financial reasons did not have any own development department more, this work fell on students of the University of Perugia, who had been employed in a study working with the modification of the Coloni. Was powered by a Cosworth DFR engine, which was prepared by the fourth race of the season at Langford & Peck and thereafter from Hart Racing Engines.
Coloni put forth only a copy of C4. The team possessed in the second half of the season in 1991 only a single engine.
The racing applications
Coloni reported the C4 in the season 1991 to 15 Grand Prix. Pedro Matos Chaves driver was at first; for the last two races of the year he was replaced by Naoki Hattori. Both pilots had no experience in Formula 1, the team was defeated during the season of pre-qualification. Chaves and Hattori failed regularly at the pre-qualification, so that no single race participation was reached. At the Grand Prix of Portugal - the home race Chaves' - the team could not even participate in the pre-qualification, as the only engine already suffered a defect while warming up in the box.
The Coloni C4B
The end of 1991, the Italian shoe manufacturer Andrea Sassetti took over parts of the Coloni teams, including the technical material and the Coloni C4. He ran in the 1992 season its own Formula 1 team under the name of Andrea Moda Formula. For the first race of the year he reported the Coloni C4B, a heavily modified in the area of the vehicle rear version of the C4, which should be driven by Enrico Bertaggia and Alex Caffi. The team was, however, excluded from participation in the first Grand Prix of 1992, so that the C4B not even contested the pre-qualification. For Brazilian Grand Prix Andrea Moda the Coloni C4B replaced by a new, constructed of Simtek car.
In the 1990s, the car was stripped down to the Cosworth engine. It changed hands several times; occasionally it was used for private test drives.
