Chevrolet has determined that it needs to redirect its marketing for the Volt in order to reach folks who would actually be interested in buying. With that, Chevy intends to offer overnight test drives for both the 2017 Volt and 2017 Bolt EV. Which doesn’t seem to far away from what Buick has done with its test drives.
While I agree that the best way for a person new to EVs to convert from gasoline is to drive an electric vehicle, I'm not conviced a driveway delivery is all that great.
I had the experience of test driving the Spark EV in freight mode, which was limited to 5mph. I've heard that some people booked Volt or LEAF test drives, and arrived to an uncharged battery pack.
IMO, getting dealership support and training is the main way to get more electric vehicles into peoples hands. People that want an EV are already researching it online, already talking on the Bolt EV Forum
It's converting the gasoline car buyer into an EV buyer that needs to be done AT THE DEALERSHIP when they come in to buy.
