I own a 2014 Volt and next month will be 10 years owning it with about 90k miles. This car is the best of both worlds with no range anxiety. Around 30-40 miles of battery range depending on the temperature outside winter vs summer. Whic is enough range for me to get to work and back on full electric. Plug it into a regular outlet overnight. If I go on a longer trip, the engine kicks in to charge the batteries and then I'm still getting 40mpg. My combined mpg electric/gas in 10 years is 90mpg. I love that I can control when I go into electric mode for times I'm in traffice for better efficiency or when I just want to use the gas like on a cold day to warm up the car faster and not deplete the battery. Since its a hatchback I can fit a lot of things in the car. Way less maintenance than my former pure ice vehicles, haven't changed the brakes yet since I owned it due to the regin bracking and my driving style.
Sad that they disconntinued it, but If they put the voltec system in another car I'll look to buy that one.
