The Bolt (and two other cars) are on the cover of Car and Driver for September.
There's an article ("Nuts About Bolt") with pictures. Little new in terms of concrete information, but it gives driving impressions. Here are a few quotes.
Jab the accelerator and the Bolt makes good on its name...the seats of our pants suggest than seven seconds is conservative. Right pedal down, this front-drive hatchback tears out of the hole and scratches for traction in bends....
...the Bolt's every motion is well managed when you toss it around. Without imposing harshness, the ride is firm to help keep body roll in check....
...steering is slack-free on-center, quick to respond, and nicely weighted.
Frankly, we see little crossover vehicle in the Bolt's genes.
Curb weight is 3600 lbs with 56/44 front/rear.Yardsticks aside, the Bolt feels roomy, able to swallow everything short of four-by-eight building materials. Entering the front seat is a horizontal slide, with little up or down translation necessary. The rear bench is chair high with ample footroom....While there are three belts in back, there's only enough witdth to carry that many kids. Two adults fit nicely with the center armrest deployed.
