The interior of the concept looks very good, almost George Jetson. If GM stays with that style it will sell cars. My concerns are this; comfort and usability. The seat is where we will spend alot of time. I am 6' 3" and about 245lbs. so if the leg room is like the new Civic I won't be driving the Volt much, instead it will be my wife's car. The seats in my Yukon XL are very easy to sit in for an extended period of time, not just from leg room but well designed for comfort. The average 12,000 miles driven per year- I almost double that. That means alot of seat time so if the seat moves back enough for tall people to be relaxed I could be wanting two Volts. Any word on the interior?
