As roblab suggests, braking with a Tesla is different than what you know with your hybrid -- at least it is from my having driven Lexus RX Hybrids the past 10 years... "Regen and letting-up on the accelerator pedal" is the single thing I made the most comments about during my MS test drive -- maybe half a dozen times -- probably because how accustomed I was with my Lexus hybrids. If your hybrid operates like both of mine did, regen occurred for the most part on the downhill, coasting, AND as you apply the brakes -- with slowing as you take your foot off the accelerator being a relatively placid thing much like it is with a traditional ICE. OTOH, MS does not regen when using the physical brakes. Instead, MS drivers that care about maximizing regen and therefore range, will learn to drive a little different as roblab suggests -- as strange as it may be to non-race-car-drivers, largely using the accelerator pedal to speed-up and slow-down, reserving the true brake pedal for emergencies, the last few feet coming to a stop, and to hold yourself in place (I won't take us off-track describing "vehicle hold").
On MS today (V7.0 firmware), regen has two settings.
- One that IMHO is much softer and feels more like, and slows MS more like, what I knew with my former hybrid as my foot came up off the accelerator
- The other setting (Standard) is what I suspect most MS drivers use (including me) the majority of the time. It slows MS MUCH more abruptly/powerfully/agressively than what you know in your hybrid. As you've seen in this thread, V7.0 of the firmware may have made some changes to this particular setting that some what I'll call "longer-term owners" want to be even more aggressive than it now appears to be. For me now, the accelerator pedal isn't quite so much of a "trigger pedal" (aka "trigger finger" if you know what I mean), and while it aggressively brings my MS to a stop as I let up on the pedal, I (and especially infrequent MS drivers) IMHO can drive more smoothly than the former 6.2 release I had for less than 10 days after having taken delivery of my new S90D...
When you take your first MS test drive some day, having come from a hybrid, you'll immediately get what I'm saying. Be sure to experiment a little: First, be sure the Regen setting is on Standard, then when no one is in front of you and not on your tail, as you are coming to a stop, note how rapidly MS will bring itself to a stop opposed to what you are used to as you release the accelerator pedal much faster than you are used to doing. THAT aggressiveness is providing regen as MS pulls itself to a stop... You can then play with being a bit more elegant releasing the accelerator pedal just a little as you approach a stop and see the effect... Hope that much longer and not as to-the-point explanation (kudos to roblab) helps further your understanding.
