How does it enhance range? Just apply light pressure to the accelerator. The energy meter shows that almost no energy is being used or that you are storing some energy and the car continues to coast forward. It is equivalent to letting the car coast in an ICE car. Let go of the accelerator completely and you get heavy regen and the car slows down fast.Why remove regen options from 2021 cars? What's the logic? Without a transmission, you need at least 2 options, to be able to 'engine brake', or 'free-wheel'. For former saves brakes on steep downhill roads, and recharges the battery pack. The latter enhances range. Looks like Tesla went into cost-cutting mode big time, not only with this, but removing chrome trim.
