Cosworth has expressed its sadness at news of Toyota's departure from Formula 1, and said the decision emphasised the need to keep pushing cost cuts forward.
British engine manufacturer Cosworth is returning the sport next year to power the new Lotus, US F1, Campos and Manor teams, plus former champion Williams - the latter having ended its Toyota deal early in order to reunite with former supplier Cosworth.
Toyota announced earlier today that it was to leave F1 with immediate effect due to the worldwide economic situation.
"The decision by Toyota Motor Corporation to withdraw from Formula 1 with immediate effect is deeply regretted but underlines the importance of all stakeholders in the sport working together to ensure a profitable and sustainable future," said Cosworth F1 boss Mark Gallagher.
"We look forward to working with the FIA, the Commercial Rights Holder, the teams and other engine manufacturers in protecting the future of Formula 1 and building on the very positive developments in the sport as reflected in Sunday's inaugural Abu Dhabi Grand Prix."
