The new Polo GTI is quite competent in its class, but if, for whatever reason, any owner wants to mix it with sports cars, they might want to get in touch with Siemoneit Racing and ask for their Stage 3 upgrade.

The German tuner will install a larger turbocharger and intercooler, optimize the air intake and other parts and add a new exhaust system with Euro 6 catalysts and controlled flaps.

They will then remap the engine software and, when everything will be fine-tuned, the 2.0-liter turbocharged four-cylinder will produce a non-too-shabby 320 PS (315 hp / 235 kW) and 430 Nm (317 lb-ft) of torque.

The 120 PS (118 hp / 88 kW) and 110 Nm (81 lb-ft) of torque increase over the stock Polo GTI has shaved half a second from the 0-100 km/h (0-62 mph) sprint, which according to VW takes 6.7 seconds, and top speed has gone up from 247 to 256 km/h (153-159 mph).

Siemoneit Racing recommends getting their 18-inch wheels, shod in 215/40 rubber, as well as a KW suspension they offer, in order to better exploit those extra horses. Finally, they can also fit Recaro sport seats, Sabelt seatbelts and Weichers Sport roll bars.

A couple of more modest technical upgrades are also available for the hot supermini, which bump the output to 245 PS (242 hp / 180 kW) or 250 PS (246 hp / 184 kW), respectively. In terms of pricing, the lesser power bumps cost just €598 and €698 ($667-$778), respectively, whereas Stage 3 will burn an considerable €8,998 ($10,030) hole in your pocket. The rest of the aftermarket parts will set you back €11,630 ($12,963) – or more than a new Up! in Germany…
