Alfa Romeo Racing C41 L
aunched in Warsaw, Poland, Sauber Engineering unveiled the 2021 contender the: Alfa Romeo Racing C41.
The C41 shares a lot of common parts with the C39, simply because of the regulations that were voted in as a result of the pandemic. Development of some parts had to be frozen for example, we had to carry over the chassis, the gearbox and many other elements like the cooling system. The regulations allow to invest two so-called development tokens to carry out changes and we chose to use them on the nosecone. It is a very unusual situation in Formula 1 not to be able to build an entire new car for the new season, but it makes sense in these circumstances and with the objective of keeping costs under control. – Jan Monchaux, Technical Director • Survival cell: Alfa Romeo Racing ORLEN Carbon-composite monocoque – homologated 2020 • Nosecone: Alfa Romeo Racing ORLEN Carbon-composite structure – 2 tokens towards homologated components freeze • Front suspension: Double wishbone, inboard spring with Öhlins and Multimatics damper units actuated by pushrods • Rear suspension: Multilink, inboard hydraulic suspension actuated by pullrods • Brakes: Brembo 6 piston brake callipers.
