If you weren't impressed with the Nissan Leaf's all-electric engine, maybe you'll at least raise an eyebrow at this Xbox-esque achievement system Nissan worked into the Leaf's software, which ranks your energy efficiency against other owners.

In addition to comparing the amount of miles you can travel for every kilowatt hour consumed, it will also give you platinum, gold, silver or bronze distinctions for maintaining a certain standard on the road. So whether you're green, or just hypercompetitive, the Leaf is right up your alley. [MyNissanLeaf via AutoBlog Green via Crave]
