FUJIMI 1/24th F1 FERRARI 126 CK 1981. High quality, detailed plastic car kit in 1/24th scale from Fujimi.
The Ferrari 126C was designed to replace the highly successful but obsolete 312T series in use since 1975. The basic chassis was almost identical to the previous car but the smaller and narrower V6 engine with forced induction, better suiting the ground effect aerodynamics now needed to be competitive (the previous car's wide flat-12 boxer engine obstructed the airflow necessary to generate efficient ground effect), and was a better package overall. During engine development Ferrari started experimenting with a Comprex pressure wave supercharger, supplied by a Swiss company; this car version was initially called 126BBC from the name of Brown Boveri Comprex and later named 126CX. The system was praised by drivers for driving like a naturally aspirated engine but having an extended power range, thus eliminating the notorious lag of the turbocharger. However the system was rather tall in the car and there could be some mixing of exhaust and intake gas so the team opted for the fitment of twin KKK turbochargers producing around 600 bhp (447 kW; 608 PS) in qualifying trim, detuned to 550 bhp (410 kW; 558 PS) in race trim. The car fitted with turbochargers was called 126CK.
Enzo Ferrari had hired Nicola Materazzi in December 1979 to work with Forghieri and Tomaini and specifically for his experience with the turbocharging in the Lancia Stratos Gr 5 Silhouette cars. He would bring technical know-how in the team to match the knowledge that Renault had built over time. Materazzi thus saw the advantages of the comprex system but also its difficulties and prepared also a second iteration with two smaller Comprex systems driven by hydraulic clutch instead of a belt but this was not used since the turbocharger was deemed simpler and worth pursuing. Hence Materazzi proceeded to perfect the following iterations of powertrain to obtain increased power and reliability.
The 126CK was first tested during the Italian Grand Prix in 1980. In testing it proved far faster than the 312T5 chassis the team were then using and Gilles Villeneuve preferred it, though he had reservations about the handling. Early unreliability of the turbo engine put paid to Villeneuve's 1981 championship hopes but he did score back to back victories in Monaco and Spain, as well as several podium places. Because of the problematic handling the 126CK was at its best on fast tracks with long straights such as Hockenheim, Monza and Buenos Aires. The car proved to be very fast but Gilles Villeneuve found the handling to be very difficult, calling the car "a big red Cadillac".
According to Villeneuve's teammate Didier Pironi and English engineer Harvey Postlethwaite, who arrived at Ferrari well into the 1981 season, it was not the chassis that was the main cause of the car's handling problems, but the very bad aerodynamics of the car. Postlethwaite later said that the 126CK "had a quarter of the downforce that the Williams or Brabham had that year". The poor aerodynamics of the car, coupled to the chassis' hard suspension (all teams in 1981 were running with hard suspensions to increase aerodynamic efficiency), created a tendency to make the car slide into corners before the ground effect pulled the car back on to the track. This had the undesired effects of exposing the drivers to even larger g-forces than the Williams FW07 or Brabham BT49 and making the car tend to overuse its tyres. The engine had massive turbo lag, followed by a steep power curve, and this upset the balance of the chassis. Although the Ferrari engine was the most powerful engine that year, even more so than the Renault - the combination of a severe lack of downforce and an abruptly powerful engine made the car an annoying menace to race against. At the osterreichring one gaggle of 6 naturally aspirated, better handling cars formed behind Didier Pironi for a number of laps, followed by three other cars shortly afterwards: none of them, however, could find their way past easily due to the Ferrari's power advantage on the very fast Austrian circuit, even though the car was very clearly slower going through the Austrian circuit's fast, sweeping corners. The same thing also happened at Jarama that year; 4 cars were stuck behind Villeneuve on the tight and twisty circuit, but he was able to hold off the cars behind him thanks to the car's power advantage and fair mechanical grip. Monaco and (less so) Jarama were slow circuits where aerodynamic downforce was not as important as mechanical grip, so combined with Villeneuve's famed ability behind the wheel the car was able to perform better than expected at these two races.
