There is a huge difference in efficiency of any car in different temperatures. ICE, diesel, hybrid, PHEV, and BEV. The difference in four season climates is striking in a hybrid, and if you Google why hybrids "get bad mileage" in the wintertime, you will find plenty of write ups. Still better mpg than a regular car though.Hybrids generally don't provide very much all electric range, so there wont be much difference in their efficiency depending on temperature.
Nearly all of the tesla fires have been the result of pretty serious damage to the battery pack. I'm going to guess this latest one will prove similar. The driver claims he didn't hit anything, but it could have happened on a previous drive. I'm sure Tesla and the fire dept will do a full investigation as to the cause.Dunno If any of you remember the Fiskar EV, but it failed hugely with fires esp here in SoCal. Starting to see some anecdotal reports involving Tesla's as well. One caught fire in Santa Monica CA just a few days ago. Apparently no "official" cause as of yet. Hope it's OK to post this link:
