To accommodate the new engine, suspension tweaks will be needed to support the added mass.
The four-cylinder Golf R 333 already benefits from 1.5deg of negative front camber, stiffer rear subframe mounts, bespoke software calibration for the adaptive dampers and reprofiled bushings. However, the required changes may include a move to 2.0deg of negative front camber, upgraded top mounts, reinforced knuckles and additional chassis bracing to increase torsional rigidity.
The RS3 also uses a stiffer front axle layout with bespoke pivot bearings to sharpen initial turn-in. Similar hardware could find its way into the Golf R if packaging allows.
The addition of the five-cylinder engine is expected to bring a modest weight increase over the current Golf R’s 1545kg. Given that the near-technically identical RS3 tips the scales at around 1570kg, the five-cylinder Golf R is likely gain around 25kg.
To keep weight down, forged aluminium Warmenau wheels are expected to feature. They’re likely to be shod with the semi-slick Bridgestone Potenza Race tyres already used on the Golf GTI Edition 50. Wider tracks and recalibrated software are also anticipated to increase grip and control.
Bigger brakes will be needed to cope with the extra power. For reference, the Golf R 333 has 357mm steel discs, with the RS3 using 380mm carbon-ceramics.
