Formula One supremo Bernie Ecclestone is pushing for the sport to introduce a standard engine as soon as 2010.
Amid a renewed drive to drastically reduce costs, with FIA president Max Mosley warning the sport must act now if it is to survive beyond next year, Ecclestone suggests the use of a single specification of engine is the best way forward.
Speaking to The Times, Ecclestone said: "The thing I am most excited about is pushing and pushing and pushing the homologated engine idea.
"The new engine will be equalised and there will only be two engine changes a year, so costs are going to dramatically come down, and I mean dramatically."
According to The Times, teams would use just two engines per car each season.
Each power unit would be built to a standard specification by manufacturers, who would also be able to badge it with their own name. Independent teams would have access to the engines through an independent contractor.
