The GMC Terrain had a number of different engine configurations over the lifespan of the vehicle but the towing capacity basically stayed the same throughout the years and varied based on the engine you had equipped.
I organized the Towing specs I found for the GMC Terrain by year and by engine to make it a little easier to scan through the information. All of the towing charts below are for the Terrain specifically.
Overview of the Data For the GMC Terrain:
Engine Choices: Over the years, the GMC Terrain's had many different engine choices and the engine that was equipped was really the main determining factor when it came to towing capacity numbers.
Configurations: The two main options for the Terrains came down to either a FED model or an AWD model but none of these configurations made any difference when it came to the specs or weight capacities, as you can see in the towing charts listed on this page.
Towing Capacity: Over the years, the towing capacity for the Terrains did not vary at all and was either a 1,500 pound capacity or a 3,500 pound capacity.
GMC Terrain Towing Capacity Summary:
The towing capacity for the GMC Terrain was either 1,500 lbs. or 3,500 lbs. and really had no range, it was either-or. The engine that was equipped was the main deciding factor when it came to towing capacity for the Terrain's.
The 2018-2020 GMC Terrain's had a towing capacity that was either 1,500 pounds or 3,500 pounds, depending on the engine you had equipped in the vehicle.
The 1.5L and 1.6L engines had the lower 1,500 pound capacity and the 2.0L engine had that higher 3,500 pound rating.
The chart below shows the towing numbers for the Terrain and the Terrain Denali and whether the vehicle was FWD or AWD didn't seem to affect the statistics at all.
GMC Terrain's that were made from 2013-2017 had the same towing capacity of either 1,500 pounds or 3,500 pounds, like the 2018 and 2019 models but had different engine options.
The 2013-2017 Terrain's had either a 2.4L engine equipped or a 3.6L engine. The 2.4L engine had the lower 1,500 pound rating, while the 3.6L engine boasted the 3,500 pound rating.
The 2013-2017 towing charts, shown below does break up the Terrains into FWD and AWD models in the chart but these configurations did not affect the overall towing capacity numbers.
The 2010-2012 GMC Terrain's still had that 1,500 or 3,500 pound maximum towing capacity like we saw in the other model years but again, the engine choices were slightly different and even the axle ratios differed.
The engine options you had for the 2010-2012 Terrain's were either a 2.4L or 3.0L engine.
The 2.4L engine for the Terrains had the lower 1,500 pound capacity and the 3.0L engine had the higher 3,500 pound capacity, according to the charts I found. Yet again, the FWD and AWD configurations of the vehicles did not affect the capacity numbers at all.
The 2011 towing chart for the Terrain (below) had the GCWRs listed, along with the GVWR and the payload capacities which was nice to have all of those metrics on one chart and would have been very helpful if they were included in all of the model year's charts.
If you notice that I have missed or overlooked anything in the article, please feel free to leave me a comment and I will gladly address the matter. Thanks for stopping by!
Resources For The GMC Terrain:
I always like to include some resources for other people out there that like to do their own research and decided to include the links to the GMC Terrain's owner's manuals. These have the towing specs listed and give other helpful towing info related to the vehicle.
Note: I used GMC's Trailering Guides for most of the tables above but the specs listed in the owner's manuals are identical and offer a better resource.
