как-то интересовался. склоняюсь к этому.
From transmission, power was set to the four wheels through an all wheel drive (AWD) system composed of a center VCU (Viscous Coupling Unit) differential sending torque to the open front and the limited-slip rear differentials. The Viscous Real-time 4WD system, from where the term "VR4" comes, is not a front-wheel drive w/ rear-assist system. Assuming that the VR4 system is simply a modification of the front wheel drive unit of the non-turbo cars (to allow it to send torque to the rear if needed) is a common mistake. Under ideal conditions, the system transfers 45% of available torque to the front and 55% to the rear, however the viscous center can send up to 95% of the torque to either axle.
A standard four wheel steering (4WS) system turned the rear wheels up to 1.5 degrees in-phase (same direction as the front wheels) when traveling at 30 mph or more, supposedly to improve very high speed stability.
аббревиатура VR-4 обсуждается на многих форумах 3000гт вр-4 и единого мнения нет.
многие склоняются именно к совокупности всех факторов+турбо.
даже приводится примеры, что у Галант ВР-4 управляемые задние колеса. но у нас то этого уже нет...
