Felipe Massa handled the debut running and gave Sauber an encouraging start to an important winter programme. The Brazilian completed 64 laps on the first day in the car and helped the team move through its initial checks, including basic systems, cooling behaviour and early balance work. That made the session more than a ceremonial launch. It was the first real opportunity to see whether the C24 behaved as expected once it left the design office and wind tunnel.
The car carried added technical interest because it was the first Sauber chassis developed using the team’s new wind tunnel. It also reflected the aerodynamic compromises forced by the 2005 regulations, which reduced downforce and made stability a more visible challenge for every team on the grid.
Massa’s role therefore mattered. He was not simply putting mileage on a new car, but helping the engineers understand how the C24 responded to set-up changes and where early development effort would be needed. Sauber continued to build mileage in Valencia over the following days, with Massa completing another solid test day before Jacques Villeneuve took over.
The significance of 16 January 2005 lies in that first clean step. The C24’s launch gave Sauber working data, reasonable reliability and a foundation for the rest of its pre-season development.
