I know there are some Volt lovers out there so I don't want to offend anyone, but this was my experience with test driving the Volt...
Cost: It is basically a $20,000 car that costs $40,000. It's interior, exterior, ride quality etc. is comparable with low priced compact cars.
Seats: Basically horrible, even on the loaded models. I am not sure why they don't understand that comfortable, supportive seats are important to consumers? No lumber support offered on any models.
Space: I am 5'8" 135 lbs so I don't require much space, but I felt cramped in the Volt, the high middle console (where they put the battery) makes the interior feel claustrophobic.
Visibility: Small windows, low seats and many blind spots.
Infotainment System: It possesses all the tasteful bling and functionality of a Vegas casino.
Gas engine: The entire time I was test driving the Volt the gas engine kept coming on for "engine maintenance", the battery was charged so I am not sure why it was cycling, but when it did, it sounded like a 1990 Corolla.
On the bright side, it did have smooth EV acceleration (although tepid) and decent regen braking (about half of Tesla regen).
In the end, I was more impressed with the $22,000 2016 turbocharged 1.5L Honda Civic, but, of course, it is hard to very impressed with any car once you have driven a Tesla.
