To cut fuel consumption and emissions as much as possible, VW is installing a mild hybrid system in the Golf equipped with the gasoline engines. These will carry the eTSI badge and will be offered in three different outputs: a 1.0-liter three-cylinder unit with 110 hp (81 kW) and a 1.5-liter four-cylinder with either 130 hp (96 kW) or 150 hp (110 kW). Regardless of the one you go for, the engine is going to be hooked up exclusively to a seven-speed DSG.
These eTSI Golfs are going to use a 48-V belt starter generator, a 48-V lithium-ion battery pack, and a brake energy recuperation function. To save even more fuel, the mild hybrid powertrains enable coasting with the engine completely turned off. Performance off the line is also improved thanks to the electric boost and firing up the engine is smoother due to the 48-V system, so it’s a win-win-win situation.
