Regen Efficiency

[jerry33]

If I read correctly the Model S also has 2 levels of regen and the brakes will regen as well, so the above should apply as well. On my Fusion, I can go into high regen quickly by dropping into low gear as on my car it doesn't do anything but increase the regen rate making it FEEL like low gear. How fast can you get into high regen from low regen on the Model S?

Not that fast, but in practice it doesn't matter because you can regulate the regen with your foot.
