The dissassembly of the engine of the Chevy Bolt EV is fascinating. It's very different then a conventional gasoline automobile under the hood.

I am actually surprised how truly different the power train is -- and in many ways simpler then a gasser or diesel -- no emissions equipment, no transmission or gear box. Nearly every component is electrical, there is no serpentine belt or alternator. Interestingly enough, the cabin heat uses anti-freeze like a conventional automobile.
