In 1908 Acme created a new 6 cylinder 45 hp runabout capable of 76 mph, the Type XXI. The company entered the car in the 360 mile long race at Savannah on 18–19 March with Malcolm Newstetter replacing Ed L'Engle as its driver. It also announced that they intended to enter their cars in hill climbing and endurance races, but not "races where chance plays a large part". The Acme car came third in a time of 6:47:05. It was beaten by an Italian Isotta Fraschini (6:21:20) and an Apperson (6:44:37).
