ZF's exothermic seat belts could help EVs go 15 percent further

EV's are notorious for losing range in cold weather in part because energy that would otherwise be used to propel the vehicle forward is instead diverted to warm the vehicle cabin. Prototype "heat belts" (oh I get it, a pun) from ZF could help eliminate that thermal waste by using the same principle as an electric blanket.

Essentially, instead of trying to warm all of the air in the cabin, ZF's 70W heat belts warm up just the front of the driver's torso and pelvis. "In combination with heated...
