The AWD system allows for three torque-split settings: Front, with a 60/40 front/rear split; Track, with a 50/50 split, and Rear, with a 30/70 split. How does it work? I spoke with Naoyuki Sakamoto, GR Corolla’s chief engineer, to learn all about it!

It’s so simple and so effective that I was shocked that most other performance cars haven’t adopted it.The short answer that clears all the confusion is the JTEKT-supplied clutch pack known as the Intelligent Torque Controlled Coupling.

It makes use of a diamond-like coating applied on 12 pairs of clutch plates that give it durability. This unit makes sure that the rear differential is always geared approximately 1% faster than the front differential.Engineering Explained takes it from the very beginning and explains everything you need to know with good visuals.
