Following a resurgence for the MG brand in the beginnings of the 21st century, the decision was made to expand the brand into motorsports such as touring car racing as well as sports car racing. MG had previously had success at the 24 Hours of Le Mans many decades ago, yet had never scored an overall win. At approximately the same time, the Automobile Club de l'Ouest (ACO) had changed the Le Mans Prototype regulations for Le Mans, making it possible for two different classes of prototype to be capable of taking an overall win. This class, known as LMP675, would use smaller turbocharged engines yet would be lighter and more nimble, making it possible for them to compete with the larger, more powerful LMP900 class.
