Simona de Silvestro will join Tony Kanaan at KV Racing Technology for the 2013 IndyCar Series.
Swiss driver de Silvestro, who has spent the past three years with the single-car HVM squad, is expected to make her debut with KV in testing at Barber on Monday.
As well as giving the 24-year-old a team-mate for the first time in her IndyCar career, the deal will also allow de Silvestro access to Chevrolet engines after having been the only driver to run the entire 2012 season with Lotus equipment. She will continue to be backed by Nuclear Clean Air Energy.
Although it was previously believed that there was potential for KV and HVM to work together in tandem, AUTOSPORT understands that there will in fact be no HVM involvement in de Silvestro's programme.
KV representatives could not be reached for comment.
