According to Autocar, Volkswagen is developing a range-topping Golf R Plus model that would be positioned above the next-generation Golf R and rival the Mercedes-AMG A45 and Audi RS3 hot hatchbacks. It will reportedly utilize hardware and technology from the seventh-generation Golf R400 concept shown in 2014 and the Golf TCR race car developed by Volkswagen Motorsport. The secret model is being developed alongside the standard version of the new Golf R at VW's R&D headquarters in Braunschweig, Germany.

Insiders claim the new range-topping Golf R Plus will be the "most extreme and powerful Golf yet." In terms of performance, the Golf R Plus is being compared to the R400 Concept, which could hit 0-62 mph in 3.9 seconds and achieve a top speed of 174 mph.

Under the hood will be an Audi-developed turbocharged 2.0-liter gasoline engine that's said to produce between 380 and 400 hp. In the new Golf R, this unit is expected to deliver around 320 hp. Power will be sent to all four wheels through a dual-clutch, seven-speed automatic transmission offered as standard.
