Archibald Frazer-Nash and Ron Godfrey made the GN cyclecar until splitting up in 1922 after the Austin Seven signalled the death of the Cyclecar. Godfrey carried on but Frazer-Nash founded a car company under his own name. Frazer-Nash chose to retain the chain drive transmission which had a separate chain for each gear and enabled quick swapping of cogs to alter ratios for different events. The first FN cars used a Power Plus 1.5-litre engine but a British Anzani engine of similar size was soon specified as well as a Meadows engine. The Super Sports continued until 1931 when Frazer-Nash won the Tourist Trophy Race and a new TT Replica went into production. Aldington Motors took over Frazer-Nash in the late 1920s when they went into receivership. In 1932 the Ulster was announced employing a 1,498cc supercharged Meadows engine. From 1934 Aldington imported and assembled BMW cars which they sold as 'Frazer-Nash BMW' until 1939. After the War Frazer-Nash acquired rights to the BMW 328 engine through Bristol Motors and postwar Frazer-Nash cars used this engine with shaft drive.
