Guys, this is what I mean regarding the "100%" power to the rear wheels capability not being what it seems to imply. Post 84 (quoted below) is from the Haldex Comp. Controller thread in VW Vortex. The reply (in red) is from HPA Motorsports who make the Haldex controller. The Haldex on the incoming 2015 R may be different but it'd be a huge undertaking to engineer a "true" 100% on-demand bias to the rear.

" (pulled directly from vw sales website.) First, is this true? Second , does your controller still allow my golf R to become almost 100% rear wheel drive or is always 50/50?


100 percent of available torque = 50:50 as there is a mechanical relationship through the front Diff. the rate at which the all wheel drive is engaged is now immediate with our controller instead of gradual.
