During the summer break, BMW Sauber announced their withdrawal from Formula One racing due to poor results and lack of financial sustainability. The team would compete until the end of the season, while BMW attempted to sell the organisation. Seven-time champion Michael Schumacher was originally set to replace the injured Massa, but the seat was taken by test driver Luca Badoer due to Schumacher's neck injuries. Also replaced was Renault driver Nelson Piquet Jr., who complained of unfair treatment by team management, in favour of GP2 driver Romain Grosjean.
