Sauber F1 team reveals dramatic new look on C44

The Swiss outfit has taken advantage of a two-year gap between its Alfa Romeo deal and the switch to full Audi works branding in 2026 to introduce a fluo green and black livery for its first season with Stake as sole title sponsor.

The C44 will be shaken down by Valtteri Bottas and Zhou Guanyu in a filming day in Barcelona on Friday prior to the official F1 test in Bahrain on February 21-23.

The new car is the first to be developed with the input of technical director James Key, although the project was already well under way when the former McLaren man started work at the team in September.

It features what the team calls an “aggressively redesigned” aerodynamic package and a switch from a push-rod to a pull-rod front suspension – a configuration used previously by Red Bull and McLaren, which is primarily intended to create an aero benefit.

Sauber has indicated that it has planned a more ambitious R&D programme than in the past, noting that it is “finalising some important updates that will be brought to track in the opening rounds of the championship, as the team intends to be a strong player in the development race”.

Team representative Alessandro Alunni Bravi has said the new green look is part of a conscious effort to embrace change after the Alfa Romeo years and with the team building towards Audi’s entry.

“There’s a new identity for our team, as we enter as Stake F1 Team,” said the Italian. “We saw a lot of changes, which makes this such an exciting era for us.

“There are changes in other areas. We are developing our team structure, strengthening our personnel, and this implies work is ongoing in Hinwil in all areas. It’s a new exciting era for our team.”

Alunni Bravi has said that the team has developed an improved car – although there was similar optimism in the camp last year – while acknowledging that the C44’s potential can only be judged against the progress made by rivals.

“Being at the start of this new era doesn’t mean we’ll get better performance immediately,” he said. “Everything we have done during this winter, however, makes us optimistic that we can make a step forward.

“We have worked hard under the direction of our new technical director, James Key, to…
