Here in hilly Austin my 1st gen numbers generally match the EPA for a mix of city and highway if the temperatures are between 50 and 90F.
And this is with my driving style being fairly aggressive acceleration followed by doing my best to drive at a steady speed and anticipate the need to slow down or stop as far as possible. So, I agree with other that the EPA numbers on the Volt at least are quite easy to attain or exceed. I am glad to hear it sounds like the Bolt is continuing that trend for GM EVs.
