However, the Volt is basically just a hybrid with a bigger battery. By 2011, hybrids were pretty common, so being nervous about the tech wasn't as much of an issue. That's the point I'm trying to make: for most people, $30k is a pretty big investment. New tech is a risk, and awards like COTY go a long way to overcoming consumer resistance to that risk.
It's possible, though, that Tesla has done enough to prove out electric cars. Tesla won COTY as well.
