Mk2
At the heart of the Polo GT G40 was its 1.3 litre G40 internal combustion engine (engine ID code: PY). It displaced 1,272 cubic centimetres (77.6 cu in) from a cylinder bore of 75.0 millimetres (2.953 in), and a piston stroke of 72.0 millimetres (2.835 in). The G40s 'G-Lader' supercharger had an inlet diameter of 40 mm (1.57 in), hence the "G40" name. This G40 engine produced a maximum motive power output of 85 kilowatts (116 PS; 114 bhp) at 6,000 revolutions per minute (rpm), and generated a torque turning force of 148 newton metres (109 lbf·ft) at 3,600 rpm.
Stopping power included uprated front disc brakes, now radially ventilated, sized at 239 millimetres (9.4 in) in diameter by 20 millimetres (0.787 in) thick, with ATE single-piston sliding calipers.
Standard roadwheels were 5.5Jx13H2 ET38 silver 'Hockenheim' alloy wheels.
Performance figures indicate it could complete the standard discipline of sprinting from a standstill to 100 kilometres per hour (62.1 mph) in 8.1 seconds, and could go on to reach a maximum speed of 195 kilometres per hour (121.2 mph). Three prototype cars had been used by Volkswagen in 1985 to set a number of world endurance speed records, such as the 1.3 litre class records for speed over 24 hours, and speed over a distance of 5,000 kilometres (3,107 mi).
There have been a number of one-make race series for the Polo, starting with the 'Volkswagen Polo G40 Cup' for Mk2 (Germany) and Mk2F G40 (UK) versions. The Polo Cup championship started in 1987 with race-modified Polo G40 82 kilowatts (111 PS; 110 bhp) (with catalytic converter) and was a support race at rounds of the Deutsche Tourenwagen Meisterschaft.
