Plato has started more than 600 BTCC races and has a record 97 victories. He tested a BTC Honda Civic at Donington Park last month and has now joined the squad that took six wins last season, to drive alongside Josh Cook and Jade Edwards.
The 54-year-old, who took his titles in 2001 and 2010, has also announced that this will be his last season in the BTCC, in which he made his debut driving a Super Touring Renault Laguna in 1997.
