Technically, this is the Sauber Petronas C22
The Sauber C22
By Phil Huff
February 9 2003
The new Sauber Petronas C22 is a completely new car and not an evolution of its predecessor, the new Sauber challenger being a radical departure from last year's C21 design.
The C22 hit the road on January 13th at the Barcelona race track
for the first time and proved since then to be reliable.
Peter Sauber and his team decided to take a huge aerodynamic step forward and are looking to challenge consistently
for points in 2003. Therefore they have changed almost everything to create the C22.
The new team's in-house wind tunnel was not operational at the time the car was designed and built but the Swiss-based
team counts on it to make major improvements in the near future.

The Petronas Engine
The 03a engine is using Petronas lubricant and fuel Team Sauber Petronas is continuing its six-year co-operation with Ferrari. In Maranello, approximately 40 new engines will be built for Sauber Petronas throughout the season. The new engine in the Sauber Petronas C22 is more powerful and lighter than its predecessor. Furthermore, it has a lower gravity centre.
The Petronas 03A is based on the Ferrari works engine (to its development stage in mid-September 2002), which allowed Michael Schumacher and Rubens Barrichello to totally dominate the Formula One World Championship in the past year.
Osamu Goto, Head of Sauber Petronas engine department: "The Petronas 03A is a very competitive engine and well integrated into the C22." Already by the end of the 1990s, Petronas, the national oil and gas corporation of Malaysia, had developed its own lubricant which was further developed to suit the Formula One engine and has been used by the team since 2000 as "Syntium". In 2003, the fuel that Petronas has developed in co-operation with engineers of Sauber Petronas Engineering (SPE) will be used in Formula One. "We are confident that our new fuel will be as successful as our lubricant Syntium", maintains Dr. Hamzah Abdul Hamid, General Manager Special Projects, Corporate Planning and Development of Petronas.
