After a 30-year hiatus, it was announced in late 2017 that Alfa Romeo's brand would return to F1 racing by sponsoring Sauber. There isn't an Alfa Romeo engine in the 2018 Sauber C37, as it uses a current Ferrari power unit instead and Alfa Romeo's involvement is strictly about FCA's sponsoring the Swiss racing team. The drivers for 2018 are Charles Leclerc and Marcus Ericsson.
Jörg Zander, Sauber's technical director, says: "The car philosophy is much different to that of the C36. The aerodynamic concept has changed significantly, and the C37 has several new features in comparison to its predecessor. We are positive that the new concept offers us more opportunities and will help us to make improvements during the course of the season. The 2018 Ferrari engine will also give us a boost in terms of our performance. We hope that we will make progress with the C37 and that we are more competitive compared to 2017."
