the 0.8l is to assist the elec motor i think...
0.8-litre, two-cylinder diesel engine
Lightweight and meeting the super-stringent Euro 6 exhaust pollution regulations, this 41kW unit is designed to be used on demand, only when the driver needs acceleration or when going uphill. At other times, it remains idle.
Composite front wings
Super-light injestion-moulded wings.
22kW electric motor/pulse starter
Can either power the Golf on its own, or assist the diesel engine. It also acts as a ‘pulse starter’, spinning the engine up to speed fro seamless restarting. This is the key to the eco Golf’s frugality: the engine ramaining idle as often as possible.
