Here are the specs on the EV Smart due out in 2010 as per Popular Mechanics article that reviewed 3 new Smart EV's. I found the top speed and range disappointing and probably not practical for many U.S. drivers:
"Top speed is 75 mph and the 0-37 mph acceleration is quoted at 5.7sec, about the same as that achievable with the petrol Smart. Maximum range (with very gentle driving) is 70 miles. But you need to avoid fast acceleration and hard braking to achieve this. Brake gently, and the kinetic energy is recycled as electricity; brake hard, and the friction linings are brought into play, wasting energy as useless heat. The battery can be recharged via a conventional British 220/240 volt socket, and it takes eight hours for a full charge from empty. But it takes three and a half hours to recoup from 30 to 80 percent of its capacity. On the European Combined cycle, power consumption is about 12kW/hrs per 62 miles and at current values this costs around 0.02 Euros per kilometre ($0.05 per mile). The battery can be recharged at least 1,000 times, which in normal use gives a life of about 10 years. Currently, British firms are paying about $750 per month in leasing costs to use these little cars—plus the recharging costs, of course."
