The G60 engine was developed from the earlier, smaller version, called the G40 1.3-litre engine. This displaced 1272 cc from a bore of 75 millimetres (2.953 in), and a stroke of 72 millimetres (2.835 in). The G40s supercharger had an inlet diameter of 40 mm (1.57 in), hence the "G40" name. This G40 engine produced a maximum power of 85 kW at 5,500 rpm, and torque of 150 newton metres (111 ft·lbf) at 3,500 rpm.
