You need to read up on what coefficient of drag means because you're statement is complete nonsense. Trying to compare the Spark to a Volt or EV1 is ridiculous. Drag coefficient has nothing to do with size. A full size car has the same drag coefficient as a 1:18 scale model of the same car. 0.325 is excellent for an upright city car with 5 seats and very short length. Long sedans will always have the CD advantage over short hatchbacks.

The townside of lithium titanate I believe is that it is not as energy dense thus the battery is larger and I'd imagine heavier.

After the Fisker debacle and A123 in bankruptcy I wonder how many battery packs they can actually supply. The original announcement was for 5000 cars but I wouldn't count on them.
