Do super/hypercars with insane amounts of torque not lunge forwards after lifting off the brakes while in D and not on the gas?

Question

For example, a regular grocery-getter with enough torque just to get around simply rolls off when in D and at minimum revs.

Why do super or hypercars not just take off when the same is done? I would assume that the amount of torque at the same rev range would be significantly higher for example in an Agera versus an Accord.

Answer 1

The force transmitted by a torque converter in automatic cars depends on the slip. This is the difference between RPM and (geared) wheel speed. A stationary car has a wheel speed of 0, and a fairly low slip given by the engine speed.

At idle, the force is low. Increasing the RPM increases the slip and thus force. A stronger engine can achieve a higher slip when you floor it, and so higher acceleration, without any more force during idle.
