After a two-year delay, the Detroit 3 say they will use a common standard to rate the towing capacities of their light-duty pickups.

Automotive News reported that the standard will allow shoppers to compare accurately the towing capability of pickups. It also should reduce confusing claims from automakers.

The marketing confusion won’t end, though, because the standard applies only to light-duty pickups. For heavy-duty pickups, automakers will still rate their vehicles with their own standards.

Spokesmen for Ford Motor Co. and Chrysler Group confirmed last week that they will join Toyota in using a towing standard adopted by the industry in 2009 to rate 2015-model full-sized light-duty pickups. A spokesman for General Motors said it, too, will adopt the standard if its competitors do.

The standard establishes various tests for towing.

Under the automakers’ 2009 agreement, the standard — which is likely to reduce rated towing capacities by several hundred pounds — was to be in place for the 2013 model year. But Ford decided not to publish lower tow ratings for its 2013 F-150, spurring other automakers to follow suit.

Toyota was the only pickup maker to adopt the standard, called SAE J2807, and it did so two years early for the 2011 model year when it dropped the tow ratings for its full-sized Tundra pickup by 400 pounds.
