Alfa Romeo has fifteen points ahead of Aston Martin in the constructors’ championship, an important bearing, but not enough to be able to sleep peacefully and hope to confirm sixth place without rolling up our sleeves. The Swiss team thus brings an important update to Suzuka, the most significant since the summer break. In detail, a revolutionized front wing was tested on the C42, comparing it with the previous specification used up to Singapore.
By observing the new aileron, you can see how many areas of intervention are, both in the trend of the upper flaps and in the coupling to the nose. The innermost fixed portion of the two upper profiles has been significantly shortened, thereby enlarging the adjustable section. For Alfa Romeo, the front load adjustment options are thus increased to correct the aerodynamic balance of the C42. From another perspective, with the same adjustment, the change of incidence of the adjustable flap is reduced, altering the flow trend towards the rear.
The same adjustable section of the two upper profiles has been corrected. The trend is completely different, as the average chord of the two flaps has been reduced, to the advantage of efficiency. Laterally, near the endplate, the progressive decline towards the outside is still present, to exploit the outwash effect of conveying the flows outside the front wheels. Compared to the previous specification, however, the “descent” is less progressive and begins in a more lateral position.
The new front wing of Alfa Romeo constitutes a major update, correcting the entire structure of the flows that continue their path from the front end, hitting the car body. The team expects significant gains, especially in terms of stability in the fast, wide-radius corners. Suzuka thus stands as an ideal test bench for the new wing, but at the moment it has not yet been revealed whether the latest update will be used in qualifying and racing already in Japan.
