Oct.5 (GMM) Cosworth has rejected reports it will definitely bow out of Formula One after 2013.
But when asked about 2014, Cosworth's F1 chief Kim Spearman said on Friday: "If we can find a commercially sustainable way to provide a competitive platform for some potential customers, we'd like to do that.
"We are in useful negotiations with customers and hopefully we'll find a way to be in."
He confirmed Cosworth has already started work on a 2014 project.
"Oh yes," said Spearman. "We've been working on the engine for 18 months."
