updated Smart EV. The faster and longer-lasting third generation city-dweller previously scheduled for delivery in "early 2012," has just been delayed until September. According to Daimler, the culprit is "unspecified problems" at battery cell provider, Li-Tec. But before jumping to explosive conclusions, the auto maker quips there aren't any "technical or quality problems with the batteries." Curious, yet also a bummer, as frankly, a $22,000 EV with 87 miles of range couldn't come soon enough.
