In the truck realm, there’s been a lot of talk about the Society of Automotive Engineers’ measurement of towing. Commonly referred to as the J2807 standard, it formulates what a truck’s towing capacity should be, rather than what automakers make the numbers out to be. Toyota is so far the only automaker to have committed to the standard, but also features the lowest ratings in the business. Ironically, it was GM that pushed heavily for the standard in the first place, but still has yet to officially adopt it. So, why does GM have cold feet in this regard? GM Lead Development Engineer for Full-Sized Trucks, Mike Norrito, discusses with TFL Car as to why, and revealed that the marketed tow ratings for the Chevrolet Silverado and GMC Sierra are pretty darn close to what they would be under J2807.
