The Volkswagen Golf R has had its power output rating downgraded following the changes forced by the new Worldwide Harmonised Light Vehicle Test Procedure (WLTP), according to an Autocar report. “In the context of new homologations, there are adaptions for the exhaust gas treatment and for the power output.

From now on, all Golf R models will feature a 300PS (296bhp) engine,” a Volkswagen spokesperson told the magazine. In Malaysia, the Golf R gets the same powertrain, albeit with a 290 PS output for local conditions.

It is thought that the stricter emissions limits of the WLTP has forced automakers to install more restrictive exhaust systems in order to limit real-world nitrogen oxide output, since the testing is now based on real-world results rather than the lab-based procedures of the outgoing New European Driving Cycle (NEDC). This affects cars currently on order, and VW will contact owners to inform them of the changes.

This has seen the Seat Leon Cupra, which also sports a 2.0 litre TSI engine, undergo a similar change, the report added. The change in emissions regulations has also seen to the discontinuation of the F80 BMW M3, as it would require the installation of a particulate filter and need to be rehomologated, preventing the F80 from going on sale before the next-generation G20 3 Series is introduced in October.
