Chevy Volt Tour

[Automobiles]

Is this an EV? Will it leave you stranded in the middle of nowhere if it runs out of juice? How safe is it? These are the sorts of questions we'll answer. Check out Chevrolet's Extended Range Electric Vehicle, achieving awards in both innovation and safety, and leading America another step away from its dependence on petroleum.

4:22, Bad News Racing and also Wait4me performance can hack the Volt so the speed limit is more like 120MPH

7:37, the battery is not that limited in cold weather, as long as it is heated with wall power before your trip. Yes if it's something like 0F or colder and the pack is also that cold it might not work well and will need the engine, but otherwise if heated with wall power before your trip, engine is not necessarily needed. The engine being on in cold weather is known as ERDTT (Engine Running Due To Temperature).

For 2011 and 2012 Volts it comes on at 25 F or colder. 2013 and newer Volt you can configure it for either 35F or 15F.

The purpose of the engine coming on is NOT to heat the battery, since it can't, engine coolant does not heat the battery. Rather the engine comes on to heat the cabin, which is annoying if you want to save gas by just having the seat warmers on but leaving the vent heat off.

You can bypass ERDTT by replacing the climate control ambient air temperature sensor with a fixed resistor, by the front grille. This tricks the car into thinking it is warmer than it really is. If it's super cold out, below -10F for instance and it hasn't been plugged in so it can't keep the battery warm from shore power, you may really need the engine as there just isn't enough energy / low enough resistance in the pack to provide adequate acceleration and self-heating, but it may be able to do it. I don't know.
