Talk of 1 Series models being spiritual successors to 3 Series models isn't new – part of the clamor around the 1 Series M was that it channeled the light flickability of the first M3s. A 1 Series sedan would serve three purposes: get a light, small, RWD model back in the lineup, give the company a clear competitor to the upcoming Audi A3 sedan and Mercedes-Benz CLA, and help BMW get closer to its sales target of two million cars in 2020.
The sedan would sit on a derivative of the platform used in the current 3 Series, and be different from the front-wheel-drive platform underpinning the forthcoming 1 Series GT. Four- and six-cylinder engines and BMWs xDrive AWD system are in the planning mix, as is an electric version. Autocar says 2015 is a potential sale date for the sedan, which would put it one year after the next-generation coupe and convertible officially bow.
