At the heart of the Polo GT G40 was its 1.3 litre G40 engine. It displaced from a cylinder bore of, and a piston stroke of. The G40s 'G-Lader' supercharger had a displacer width of, hence the "G40" name. This G40 engine produced a maximum power output of at 6,000 rpm, and torque of at 3,600 rpm. Stopping power came from uprated front disc brakes, now radially ventilated, sized at in diameter by thick, with ATE single-piston sliding calipers. Standard roadwheels were 13x5.5 ET38 silver 'Hockenheim' alloy wheels with 175/60 H13 tyres. Performance figures indicate it could complete the standard discipline of sprinting from a standstill to in 8.1 seconds, and could go on to reach a top speed of. 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. There have been a number of one-make race series for the Polo, starting with the 'Volkswagen Polo G40 Cup' for Mk2 and Mk2F G40 versions. The Polo Cup championship started in 1987 with race-modified Polo G40 producing and was a support race at rounds of the Deutsche Tourenwagen Meisterschaft.
Mk2F
At the time of launch of the Polo Mk2F, the highest performance model was the Polo GT with. This featured a multi-pointfuel injected version of the 1,272 cc engine, capable of propelling it from 0 - in 11.1 seconds and onto a quoted top speed of. Defining features of the Polo GT include red piping in the bumpers, black overhead cloth, a rev counter, wheel arch extensions and a red badge in the grille. Soon after the launch of the Mk2F, another sporting model was added to the range — a new version of the supercharged G40, now as a full production model in all markets, rather than the limited batch of Mk2 G40s. Engine and gearbox aside, mechanical differences between the G40 and similar looking GT included lower suspension, vented front brake discs and rose-jointed steering and track control arms. The G40 was also marked out by its Le Mans check interior trim, roof-mounted 'bee-sting' aerial and BBS 5.5Jx13 cross-spoke alloy wheels, while the speedometer topped out at 160 mph. As with the previous model, Volkswagen Motorsport modified G40 Cup cars were sold for racing in a one-make series, the Volkswagen Polo G40 Cup. A handful of these original racers are still around, and compete in the Super Coupe Cup against other brands. Sales of the G40 was marred by a comparatively high price tag and because it was based on a nine-year-old design it came with limited luxuries compared to rivals. Power steering, for example, was never an option. With the bigger, better equipped Mk2 Golf GTI 8v not much more expensive it failed to sell in large numbers. Only around 500 right hand drive models were ever made, exclusivity which combined with easy power upgrades has made it popular with enthusiasts. The model was replaced by the Polo GTI in 1995 in Western Europe, and was not directly replaced in the UK until 2000. However, the Polo Mk4 1.4 16v was the quickest Polo for the next 6 years, followed by the GTI.
