There is a thread on the GM Inside News forum discussing this topic. Apparently GM has listed the Bolt as a truck. The discussion revolves around the idea that this was done to lower the CAFE numbers for GM trucks. Trucks are where GM makes a lot of money, so more Bolts means GM can continue to sell their large trucks and still meet CAFE truck requirements. I guess this is another reason to make the Bolt a small CUV instead of a snazy sedan like the Model 3.
