1000 miles is beyond what the majority of gasoline cars can do. The real question is how much acceleration it offers.
Unfortunately, it’s only 621 miles (1000 km). If this new battery is for a hybrid with a smaller gas engine than the Prius then the government-subsidized Chevy Volt sales are going to get worse. If, however, this battery is for a fully-electric vehicle, it will be a game-changer. Fleet sales may become more viable.
Yes, but gasoline cars can be refueled in five minutes. I have been known to drive well over 600 miles a day on the way to a vacation spot. I can drive from Columbus to Panama City Beach today in 12 hours with a total of 15 minutes in fuel stops. With a 600 mile electric, I'd have to stop in Montgomery for the night and waste a vacation day...in each direction.
