    I notice a big difference in the regenerative braking between my previous 40kW and the new 60kW. My 40kW used to stop much quicker. Did anybody noticed this after upgrading from a lower kW to upper kW battery car?

    I don't notice much difference, if any, between our 60 and our 85.
    Did you check the regen setting?

    If anything, I would expect the regen in the larger battery to be stronger.

    Check the regen settings. It could be you simply have the milder of the two settings activated now.

    Nope, the lighter 60 kWh battery has stronger deceleration until you slow down below the 60 kW point, then they are both the same (0.15 g).

    If Model S is charged to 10% vs 90%, will amount of regenerated energy be the same?

    Do you mean 10% or 100%? If 10% yes, I've never noticed any difference as long as there was enough space left in the battery and the battery was warm enough. If 100% or close to it, regen will reduce or stop since there will be nowhere for the electricity to go.

    That's good! I just though if supercharging is slower when battery is closer to 100%, so will regeneration...

    The maximum regen rate is 60 kW. Superchargers can be up to 135 kW.
