With initial experience in single-seater racing, Demoustier made the jump to GT action in 2010, competing in the FFSA championship in an Aston Martin DBRS9. He also started – and finished – the Spa 24 Hours and tackled four rounds of the FIA GT3 series. Following a brief single-seater comeback at the start of 2011, Demoustier returned to GT racing and progressed to the FIA GT1 World Championship in 2012. His 2015 WTCC bid with Craft Bamboo marked a new departure for Demoustier and, after spending the year adjusting to the discipline, he has signed for Sébastien Loeb Racing for season two.
