I'm looking at these photos and I'm thinking to myself that these are quiet unconventional designs. It seems to me that everyone feels that by the time the BlueStar is built, the public will be ready for space-age looking cars. At least that's how I feel.
While the Roadster really rocks, it's body design isn't that much different from a conventional sports car. True, it's design is based on the Elise for practical reasons, but I suspect there were marketing reasons for keeping in the range of American sensibilities. The WhiteStar will probably push the envelope a little (it has to for aerodynamics). But I'm betting that it will still look fairly "normal", albeit the really hot end of normal. After all, if they expect to sell 10,000 a year it has to have fairly broad appeal.
But by the time the BlueStar is introduced, competition in the alternative car market will have really heated up in the $30,000 range. Toyota is talking about cutting the Prius into its own line of cars and even the Aptera should have a foothold by then. Tesla will want to distinguish the BlueStar from the competition, so a really unconventional and hot look would suit the BlueStar just fine.
