Over all pretty disappointing. It seems like the submissions are getting worse every year, or maybe I’m just getting more critical. At the very least these things should be nice to look at, but some of these are borderline eyesores.
The Mercedes Ener-G concept seemed a little out of place with everything else being so futuristic and far reaching, but it was probably my favorite. Apparently they made a full size prototype, some cool details going on.
