The 126C2B was the further modification s of the 126C2 model raced in 1982. Since the 1983 season FIA banned the ground effect by mandating the use of a flat bottom. In the 126C2B Harvey Postlwetwhaite introduced much larger front and rear wings which along with smaller side-pods generated around 50% of the downforce of the ground-effect aerodynamics. The V6 turbo engine was boosted to around 800 bhp in qualifying and over 650 bhp for race. The C2B were in use in the first half of the season until the 126C3 was introduced, which featured Ferrari’s first carbon-fibre composite monocoque chassis. The C3 debuted in the British GP driven by Patrick Tambay, while Arnoux get the 126C3 at the subsequent race in Germany. Tambay and Arnoux were both in contention for the world championship throughout 1983. They scored one victory each behind the wheel of 126C2B (Tambay in San Marino and Arnoux in Canada). After the introduction of 126C3 Arnoux added two more wins (at German and Dutch Grand Prix), but the car reliability problems put Ferrari drivers out of the Championship run. Arnoux finished the season on 4th position, Tambay was 5th. However, Ferrari took the constructors’ title for the second year in a row.
