Sources within VW have told Car magazine that the company will unveil the new Golf variant at the next Frankfurt motor show, which takes place in September 2015.
Under the bonnet there will be the company's most powerful 2.0-litre turbocharged four-cylinder petrol engine yet.
Final output figures have yet to be writ in stone, but expect it have between 294kW (400PS) and 309kW (420PS) of power at its disposal. If VW does decide to go with the more powerful state of tune, the car may be rechristened as the Golf R420.
Like the Golf R that it will sit above, the production car will ship with all-wheel drive as standard. There will also be an uprated braking package.
Although the super-hot Golf is inspired by the R400 concept car that was unveiled earlier this year at the Beijing motor show, it's not known how closely the production vehicle will resemble the earlier concept.
As the R400 or R420 will be a regular production model, not a limited edition job, the British publication expects the uber-Golf to be not too overt about its powertrain. At the very least there will be a revised aero package consisting of new spoilers and splitters.
