I'm comparing the regenerative braking systems of the Quattro 55 and the Q4 e-tron. The Q4 appears to use a different method to activate strong regen. The Q4's paddle shifters can be used to control how much regen is applied when you let go of the accelerator. However, when you put the car in 'B' mode, it behaves similarly to a one-pedal driving mode with extremely strong regen. Is it correct?
