The new MK VI Golf has only just gone on sale here in North America but VW engineers are already hard at work on the next iteration. When the seventh generation of VW's compact rolls out in a few years, the powertrain options will likely expand beyond the current gas and diesel variants if current plans continue. The Golf is expected to gain both a hybrid and a pure battery electric version in coming years. It's unclear if the hybrid will be based on the architecture used in the current Golf TwinDrive PHEV prototype or be something different. The TwinDrive uses a sort of series-parallel combined system with series hybrid electric drive at low speeds and blended drive at higher speeds. More likely, the Golf will get a more conventional parallel mild hybrid of the type shown in the Up! Lite concept this week in LA. This uses an electric motor sandwiched between the engine and DSG transmission. This lower cost system could allow for an affordable diesel hybrid combination. The other new model would be a pure battery EV that dispenses with the engine altogether.
