The Volkswagen G60 and G40 were inline–four-cylinder automobile petrol engines, which used a specific method of forced induction by way of a scroll-type supercharger.
[1] A smaller G40 engine of identical design was previously installed in the Mk2 Volkswagen Polo GT G40 from August 1986 to July 1994.
The crankcase contains a forged steel crankshaft which runs in five main bearings, and cast pistons with increased size gudgeon pins.
Charged air is cooled via an intercooler, and the operation and control of the engine, is managed by a Bosch Digifant engine control unit, which includes common rail electronic multi-point fuel injection and a knock sensor.
Then, this evolved into their highly regarded range of Turbocharged Direct Injection 'TDI' diesel engine.
All Volkswagen G-Lader internal combustion engines are inline four-cylinder SOHC designs, operate on the four-stroke cycle petrol engines with Bosch Digifant electronic multi-point fuel injection, are water-cooled, and use a G-Lader supercharger:
