<Tr> <Th> Successor </Th> <Td> BMW 2 Series (for coupé / convertible) </Td> </Tr> <P> The BMW 1 Series is a range of subcompact executive cars manufactured by BMW since 2004 . It is the successor to the BMW 3 Series Compact and is currently in its second generation . </P> <P> The first generation was produced in hatchback, coupe and convertible body styles . Since the second generation (introduced in 2013), the coupé and convertible models have been marketed as the 2 Series, therefore the 1 Series range no longer includes these body styles . A sedan model became available for the Chinese market in 2017 . </P> <P> The 1 Series is BMW's entry level of model range . Unusually for a small car, the 1 Series range is mostly rear - wheel drive, (except for the F52 sedan, which is front - wheel drive) with optional all - wheel drive being available on some models . </P>
