Cosworth says that it is continuing to make progress with its efforts to return to IndyCar, and that further meetings with potential manufacturer partners could take place as early as next month.
The company confirmed in February that IndyCar formed part of its plans to return its core focus to motorsport, and while it has already held initial talks with the series, any programme would require it to be partnered with an engine manufacturer.
Cosworth marketing director Tom Buckler told AUTOSPORT that conversations with potential affiliates are progressing well.
"We're talking actively to two, potentially three, manufacturers at the moment, and we're in the process of setting up some meetings, hopefully around the [Indianapolis] 500, to take that forward," he said.

"Technically, we know we can do it. We've done it before, and there's not really a doubt in the mind of Bruce Wood, our technical director, that we could design a race-winning engine.
"The business case, we believe, makes sense. We've done analysis, and the exposure the brand would get - not just from winning the 500, but even running the championship - there's a very positive ROI [return on investment] in that."
Cosworth has made even stronger progress on other fronts, with Buckler confirming that it will be involved in at least one sportscar project.
"There is one [project] that we're actively working on and another that's in the pipeline," Buckler said.
"I can't really say any more at the moment. But we will be there [in sportscars]."
Meanwhile, Cosworth has announced a new partnership with IndyCar to expand upon its existing role as a long-standing technology supplier to the series.
The Cosworth Live On Air programme will allow for data that is already streamed back to the pits via high-bandwidth radio to be made available to fans, potentially with future social media integration.
