The limited-run Volkswagen Polo R WRC Street has received the aftermarket treatment from Wimmer Rennsporttechnik.

The quickest, most powerful Polo for the public roads came out late 2012 with the Golf GTI’s turbocharged 2.0-liter four-cylinder engine. Pushing out 220 horsepower (162 kilowatts), the Polo R WRC Street is one mean supermini hitting 62 mph (100 kph) in 6.4 seconds before topping out at 151 mph (243 kph).

Wimmer wanted to prove there is room for improvement and actually managed to almost double the engine’s output, now standing at a fantastic 420 hp (309 kW). This makes it 20 hp stronger than the Golf R400 concept which by the way we are still patiently waiting to see in production guise.

To extract so much power from the four-banger, the German tuners upgraded the turbocharger, modified the high-pressure pump, and installed a custom stainless steel sports exhaust system. The intercooler has also gone through some changes and the engine’s ECU has been remapped. Thanks to all of these optimizations, the 2.0-liter now generates a torquetastic 354 lb-ft (480 newton meters), up from the series 258 lb-ft (349 Nm).

Applying this €10,200 / $11,530 stage IV upgrade kit to one of the 2,500 Polo WRC Street units built by VW will unlock a jaw-dropping top speed of 174 mph (280 kph). For those willing to spend even more, Wimmer has a set of 17-inch OZ wheels, a KW coilover suspension, and a K&N air filter.

It all sounds very impressive, but keep in mind this is still a front-wheel-drive car and with 420 hp on tap, you can imagine it’s quite tricky to tame this little beast.
