Chevy Volt's "230 mpg"? So apparently, it's expected that the new Chevy Volt is going to get a 230mpg city rating. After reading up on it, I'm not sure how it's going to work. On a "full" charge, they expect 40 miles off pure battery. Then the engine will take over to power the generator which will have up to a 50mpg rating. Now, the devil is in the details; how does the EPA calculate mpg for vehicles like this? On a long drive, I assume the rating tends towards the rating the engine/generator would have, however in the daily grind of big city driving, I can't even imagine what it would tend towards if you keep it charged all the time (charge at home then possibly charge at work? makes me wonder if a business would charge their employees to plug in their cars :P)? DISCUSS! Wait, no "discuss", i just want an answer :rofl:.
