Mitsubishi's VR4 meaning.

I remember back in the days, people knew VR4, but not the actual meaning.

It means Viscous Real time 4

Viscous coupling is found in All Wheel drive vehicles. It connects the back wheels to the front wheels and transfers energy to the back.

Real time refers to all the time or full time. This means that all wheel drive is always engaged.

4 - for 4wheel drive or all wheel drive.

VR4 is a Mitsubishi deal.
