The city car is based on the Toyota iQ's underpinnings. Automotive News reports A-M will not actually make any changes other than interior trim and a new fascia; no mechanical changes. The company plans to build 2,000 units a year and sell first
only to existing clients.
The article alludes to this being a means by which A-M can raise its average unit fuel economy. Talk about unintended regulatory consequences. If that's true it will also raise the total A-M footprint.
In light of the macro picture, the goal should be to reduce the carbon footprint of real A-M cars, even if only a modest amount. That would produce a better environmental outcome by far.
