I haven't driven the Clarity yet in the snow. With the Volt, the Regen was nice, albeit a little too aggressive (I have the 2012 with only Max Regen setting with shifter in L setting and just taking your foot off the accelerator would cause some loss of traction). With the Clarity, I think I would try the Sport setting (so the Regen stays on) and set the Regen at about 3/4 and see how that works. Gentle with the accelerator since in Sport mode, but it should let you keep from having to use the brakes very much.
