The demands imposed on the development of passenger car powertrains with combustion engines are growing increasingly complex and are beset by conflicting objectives. While politicians put pressure on the efforts made under development goals to reduce pollutant emissions and fuel consumption by introducing RDE legislation and the WLTP driving cycle, the vehicle segment is also subject to growing price pressures, particularly below mid-range vehicles. Therefore, technological measures targeting energy efficiency and emissions must be as wide-ranging as possible and have a price/performance ratio that appeals. One key step is the 48-V electrical system. The higher electrical voltage can elicit mild hybridisation in the form of different components in a range of vehicle segments. The first production start-ups have already impressively exemplified the scope of potential applications. ...
