Ford is mentioned in the article too. This is all about bragging rights for tow specs. An article published a few months ago mentioned that it will result in about a 400 lb. reduction on average. It has nothing to do with safety or misinformation. They believed they had until a model change to adopt the new standard which GM did with their 2015 models that are redesigned.
Just what is the J2807? "The Society of Automotive Engineers (SAE) has sought for the past half-decade to bring clarity to the situation, and now automakers are getting on board, too. The SAE standard, “Performance Requirements for Determining Tow-Vehicle Gross Combination Weight Rating and Trailer Weight Rating,” is known as J2807, and a big piece of it is how a laden truck climbs a grade such as the Colorado River’s Davis Dam. First published in 2008, the standard was revised in September 2010. Ford, General Motors, Ram, and Toyota have agreed to adopt SAE J2807 for the 2013 model year, and Nissan will soon follow."
