BMW (BMWG.DE) aims to double sales of large luxury cars next year from 2018 levels to help revive profit margins hit by investments in new technologies, Chief Financial Officer Nicolas Peter said on Thursday. BMW hopes to sell around 135,000 premium models such as the i8, 8-series, X7 and 7-series in 2020, up from around 65,000 in 2018, Peter told reporters in Munich.
