Toyota moved to the new ratings two years ago, resulting in tow ratings for its Tundra dropping anywhere from 400 to 1,000 pounds. When it came time for General Motors to announcing its 2013 trucks, it released towing specs based on the new standards, sending some ratings up and other down by hundreds of pounds. Ford, however, has decided that it will move to the J2807 standard when it's "all-new models come to market," which means The Blue Oval gets at least another year, probably more, to use its current figures. Predictably, GM not only cried foul, it took back the SAE numbers – even though they've been revealed – and has reverted to the pre-SAE ratings. A GM statement read, in part, "For example, key competitors are continuing to use their existing ratings for 2013 model year pickups. Retaining our existing rating system will reduce confusion for dealers and customers."
Ram hasn't disclosed its plans yet, but information on its 2013 models is expected at the end of this month and we'll know where it stands. Concerning GM, the truth is out there, you'll just have to go looking for it. Concerning the clarity everyone was hoping to find this year, well, that's still a ways off.
