Lance Armstrong "Leafs" Emissions Behind

Lance Armstrong stars in a new commercial for Nissan’s Leaf, a zero-emissions car fueled solely by electricity. (It has no tailpipe!) The model will be released in December – and Lance gets the keys to the very first one.

Nissan seems to be continually looking for innovative ways to reduce emissions; in spring, Nissan North America teamed up with academics at Carnegie Mellon University to begin developing even more eco-friendly electric cars.
