After various spy shots, it seems there is now an official press release. I also read somewhere else that to achieve the lower CO2, they looked at a variety of changes such as thinner window glass and smaller fuel tank (to reduce weight). Having just started A Class ownership in January, I would be interested in a more in depth understanding of the mechanical changes. The cosmetic changes look relatively minor. Any feedback welcome!
