Presentations 2018: A Bold and Heavily Revised Alfa-Romeo Sauber

After Haas, Williams, and Red Bull, it’s Sauber’s turn to unveil its Ferrari-powered C37. A brief overview of the notable technical developments.

First of all, the nose of the single-seater features two slots similar to those adopted by Force India since 2016 but located lower than on the Indian cars. The aim is to direct air under the car, making it more stable by gaining downforce (see photo 3).

As with the Red Bull, the suspensions are quite high and sculpted to better redirect the airflow towards the rear of the car. The structure of the suspension triangle is also designed to improve air circulation towards the side pods (see photo 2).

The side-pods do not adopt the Ferrari 2017 model, unlike the other single-seaters presented so far. They feature very narrow openings like those on the Red Bull. As with the Austrian car, fins are positioned above the side air intakes (see photo 1).

Check out close-up pics of the new Sauber C37 and its cool double sidepod inlets.

The Halo features a small ridge to improve airflow and help better cool the central air intake (see photo below).

The central air intake is similar to the one used by Mercedes on its 2010 single-seater and by Caterham in 2011. The chimney is divided into two in its main part, with two additional openings on the top. The goal is to cool the engine and compensate for the disadvantages of the Halo (see photo below).

My guess is that the turbo airbox is fed by that inlet on the sidepod. The roll hoop is used just for cooling pic.twitter.com/On0fzLiNUM— Craig Scarborough (@ScarbsTech) 20 février /f1/actualite/22505-presentations-2018-une-tendance-aux-side-pods-ferrari-2017-et-aux-t-wings-revisites.html

Regarding the rear of the car, it is interesting to note the rear diffuser, which is similar to the one used by Ferrari last year. Like on the Red Bull, the single-seater does not feature a repositioned T-Wing. In conclusion, the rear wing is supported by two pillars instead of one as was the case last year (see photo 1 below).
