Volkswagen has commenced testing procedures for a hotter version of the Golf GTI Clubsport which will receive the “S” suffix.

The most powerful front-wheel-drive Golf money can buy these days is the GTI Clubsport version which has 265 horsepower (195 kilowatts) coming from a turbocharged 2.0-liter, four-cylinder engine. It has an overboost function which upon activation will boost output of the motor to 290 hp (213 kW). Those who want the full power permanently are going to have to wait for this, the S version.

Caught on camera at the Nürburgring, the two VW prototypes may look virtually the same as the regular Golf GTI Clubsport, but there’s an extra 10 hp underneath the hood. That’s because this hotter version is expected to use the 290-hp tune of the engine which has been available for quite some time on the SEAT Leon CUPRA 290. As far as torque is concerned, it will likely remain the same at 258 pound-feet (350 newton meters).

We know for sure the three-door hot hatch will get the “S” letter because our spies tell us they saw the two cars before Volkswagen applied that black sticker above the side skirts next to the “Clubsport” lettering. It’s not known at this point whether there are going to be any other changes, but maybe the exhaust system will be tweaked to provide a more powerful soundtrack as it was the case with the car’s Spanish cousin. In addition, there was a rumor earlier this year about a lightweight variant of the GTI Clubsport and chances are this is it.

The 290-hp Golf GTI Clubsport S will be just 10 hp less powerful than the all-wheel-drive Golf R, albeit the latter has more torque 280 lb-ft (380 Nm). Chances are this hotter “S” version of the Clubsport will be an addition to the range and will be sold alongside the regular model, rather than replacing it.

Volkswagen will probably introduce the car at Wörthersee (May 4-7) during the annual GTI Meet. At the same event we could also (finally) see a production version of the Golf R400 concept. Here’s hoping.
