That Corvette ran 136 mph in the quarter so the et wasn't representative of the potential.  In addition that was 1965, think about that.  We also ran a 1968 Barracuda SS.  Our et was 10.09 best which was below the national record by about .3 or .4 seconds at the time.  Today that car runs 8.47 I believe.  

If you bring that car to about to about 65% of the country it's going to be running on coal fired electricity.  In addition the grid is old and already stressed so promoting more electricity use seems counter productive, especially with the new standards making electricity production even more expensive.

And as I said, a new ZR1 Corvette gets 25 or more MPG, runs the quarter in 10 seconds, has a top speed of 205 mph, can drive several hundred miles between refills which only take a few seconds.  It's relatively comfortable and as to cost well a comparable electric car the Tesla Roadster tops out at 125 mph, costs about $18000 more and has a range of about 200 miles after which you can spend hours recharging.
