The Ginetta-Zytek GZ09S was a LMP1-class Le Mans Prototype race car, built by Zytek Engineering following their partial merger with Ginetta. It was an evolutionary update of the Zytek 07S, with the bodywork altered for the 2009 LMP regulations. The GZ09S/2 was a LMP2-class version of the same car (for 2011, it became a LMP1-class car, due to rule changes, and became known as the Zytek 09SC.) In 2011, its successor, the Nissan-engined Zytek Z11SN, made its competitive debut, following the latest rule changes to the LMP regulations. The GZ09S was retired at the end of that season, as it was no longer eligible to compete.
