BMW in Formula One
For the 2006 season, BMW Sauber signed Nick Heidfeld from Williams to be the lead driver, while  World Champion Jacques Villeneuve had his existing two-year contract with Sauber honoured. Robert Kubica was signed as the team's third driver. The team continued to use Sauber's facilities, mostly for chassis construction and wind tunnel testing, while BMW's headquarters in Munich were responsible for building the new 2.4 litre P86 V8 engine, revised technical regulations forcing a change from the 3 litre V10 formula. This replaced the Petronas-badged Ferrari engines which the team had used since 1997. The Sauber team's existing major sponsors, Petronas and Credit Suisse, renewed their contracts with BMW. The team also announced a technical partnership with technology company Intel. The team's new livery, which was maintained throughout its tenure in Formula One, consisted of the traditional BMW blue and white with a hint of red.
