That’s interesting. Best I have is there is a “power display” which shows an analog of how much power is sent to the rear. The first metric observed is the velocity of accelerator movement. The quicker you snap the pedal down, the more burst. Depth doesn’t mean much, eg, if you ease it down, the rear might do very little.
What I haven’t observed is how aggressively it kicks the rear when the front end spins out.
Something to note - where the electronic system still has an advantage - is in a locked mechanical system, unless the fronts are slipping, the rears are simply keeping time with the front, which means that if everything is in sync, their effective force to the ground is only present if the front slips or if you’re in a turn, whereas the emotor will not be “held back” by mechanics - if power is applied, theres torque to the ground. I’m not saying in any way that one is better than the other - what I can say is the the silly little rav4H has a lot more “boogie” in it for snap-movements under 25 mph that the little ute would suggest. That drivetrain in a Corolla would be raucous.
