If automotive design interests you, take a look at these videos documenting the development of the Opel Flextreme. We covered the Opel Flextreme concept car at the 2007 Frankfurt auto show. It's essentially the Chevy Volt for Europe, using the same series hybrid powertrain. The Flextreme is a bit bigger and, most notably, it has a couple of Segways stored in its rear. If you want to find out why, watch the videos.
