G60 refers to an inline-four cylinder automobile petrol engine, which uses a specific method of forced induction - by way of a specific type of supercharger. The G60 engine was formerly manufactured by the German carmaker Volkswagen Group, and was installed in a limited number and range of 'hot hatch' cars from their Volkswagen Passenger Cars marque from August 1988 to July 1993.

A smaller G40 engine of identical design had earlier been installed in the Mk2 Volkswagen Polo GT G40 from August 1986 to July 1994.

The G60 is a 1.8-litre internal combustion engine, which displaces 1,781 cubic centimetres (108.7 cu in) from a cylinder bore of 81.0 millimetres (3.189 in), and a piston stroke of 86.4 millimetres (3.402 in). Its cylinder block is constructed from grey cast iron, and its cylinder head is cast aluminium alloy, with additional post-production heat treatment. The crankcase contains a forged steel crankshaft which runs in five main bearings, and cast pistons with increased size gudgeon pins. It has two valves per cylinder (eight valves in total), which are operated by a toothed belt-driven forged steel single overhead camshaft (SOHC) via hydraulic valve lifters, with the valves being closed by two concentric valve springs. 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. It produced a maximum rated motive power output of 118 kilowatts (160 PS; 158 bhp) at 5,800 revolutions per minute (rpm), and could generate a turning force torque of 225 newton metres (166 lbf·ft) at 4,000 rpm.
