The Ferrari 126C, successor to the 312T series, featured a narrow V6 engine with forced induction, better suited for ground effect aerodynamics. Initially experimenting with a Comprex supercharger, Ferrari switched to twin KKK turbochargers, resulting in the 126CK. Despite its powerful engine, the 126CK faced handling challenges due to poor aerodynamics and a harsh power curve. Gilles Villeneuve, who achieved notable victories with the car, criticized its handling. The car's performance varied, excelling on fast tracks but struggling on circuits requiring more downforce. The 126CK's combination of high power and low downforce made it a challenging but occasionally competitive car in the 1981 season.
