If Renault pulls out of formula one after Monday's 'crash-gate' hearing of the World Motor Sport Council, Toyota may use the opportunity to also pull the plug, according to the latest speculation.
It is expected that the meeting will result in a $50m USD fine for the French carmaker Renault, and Martin Brundle wrote in his latest Sunday Times column that it could compel executives to conclude: "We're off".
"Many think Toyota will choose the same moment to exit and this would leave Red Bull and Williams without engines," the British commentator and former driver added.
To the Cologne newspaper Express, Toyota team president John Howett played down the latest rumours.
"We signed the Concorde Agreement, therefore Toyota is bound to formula one and we are planning completely normally for next season," said the Briton.
