Neat, I hadn't heard of Auto Motor und Sport, but it's a pretty good read if you speak German, with way better coverage of green cars than American publications.
They've even got this
list of the 80 lowest-CO2 cars in Europe, and only three of them are for sale in America.
I still think of BMWs as wasteful cars with large engines and high price tags, but lately I've come to realize they actually work hard to minimize the environmental impact of their (still very thirsty) cars.
