GM Postpones SAE Standard Implementation.2
It can be recalled that SAE came up with the standards to help consumers in comparing towing ratings of trucks. 
Consumers often make comparisons before making a purchase but without a standard rate to base on, they may have a hard time finding the right vehicle for them. To address this situation, SAE, in a meeting with manufacturers and suppliers in the towing industry, set a standard aimed at helping customers compare cars, crossovers, and pickups that have a gross weight of 13,000 pounds.
After the J2807 was announced, several truck manufacturers launched recalculations in their fleets to see how they can implement the standard. GM put the towing numbers of its latest Silverado and Sierra under recalculations and found out some adjustments might be needed. Toyota, on the other hand, decided to follow most of the procedures and standards in its 2011 Tundra and Tacoma, as well as its SUV fleet. With Ford, the 2013 Fusion and Escape and other new models were recalculated. The J2807’s effect on Ford’s F-Series pickup is something that analysts are interested in, as they await Ford’s move in this matter. Nissan and Honda are among the manufacturers that are yet to release their plans involving their 2013 line-up but experts don’t expect any major changes in their numbers.
