Rumors emanating like a cloud of gas from Aunt Mable's Thanksgiving table are coming out of Bloomberg regarding the possible move at GM to push for unibody construction on full size SUVs. While there isn't anything inherently dumb about this idea, we have to question the impact on brand perception, long term durability, towing capability, chassis complexity, production line capability, and competitive impact. Hmm. Maybe it is a little dumb.

Anyway, the push for the new architecture has a target date of 2012, or just about the time gas hits $15,000 a gallon in the US, so the idea is to provide room and size while reducing weight and improving gas mileage. We're wondering why they don't just follow through with the Autonomy concept that they spent so much money (and the motoring press spent so much time) on. [Bloomberg via Carscoop]
