The Types of EVs That Can Tow
An EV is just as sturdy as the gas-powered car next to it, with a model for almost every budget these days. Just like other types of cars, most EVs can tow at least a lightweight load.
Not every gasoline-powered car on the road, however, is capable of towing heavy loads such as other vehicles or trailers. It’s the same with an EV.
That’s because the smaller any car is, the less likely it’s capable of towing a heavy load. All cars have weight ratings that dictate how much they can safely tow; even those with very low ratings still might be able to tow a lightweight bike trailer or something similar.
It’s the same with EVs. EV manufacturers have taken towing into consideration and nearly all EVs can physically tow a trailer of some sort. The key issue ultimately comes down to weight ratings.
What to Look For When Gauging EV Towing Capacity
When you’re looking at purchasing an EV, check for the vehicle’s gross vehicle weight rating (GVWR) and gross combined weight rating (GCWR). These numbers will give you good insights into how much weight the particular model you’re looking at can tow.
GVWR: This is the vehicle’s maximum loaded weight (with passengers and cargo). GCWR: This is the vehicle’s maximum loaded weight plus the loaded weight of a trailer.
EVs are heavy by nature due to the battery pack weight; the GVWR and GCWR represent the heaviest weight the EV can safely operate. These weights factor in things like braking distances, maneuverability, and driving range. The more weight involved, the more time drivers require to make adjustments on the road.
So how much an EV can tow will depend upon the specific make and model involved. Towing a lightweight bike trailer is very different from towing a heavy horse trailer, for example, or another vehicle.
Just like with any other car, knowing what you need to tow before you buy is important. An SUV or truck is likely a better EV option than a smaller, compact EV for some people but if you never need to tow heavy weights, the type of EV you purchase wouldn’t be much of an issue.
How Towing Impacts Range
The average internal combustion vehicle, when towing, loses about 40 percent of its fuel economy, according to HowStuffWorks. Some manufacturers estimate that EV range can drop by as much as 40 to 50 percent when an EV tows a trailer.
While this estimate is, of course, impacted by the actual weight your EV is towing plus the drag involved (effect of the wind against the vehicle), range is an important towing consideration regardless.
The type of tow also impacts range: A closed hauling trailer is likely to produce more drag than an open-bed trailer. The more drag introduced, the tougher the pull is for the EV and the faster range will drop.
Understanding things like this just means you need to plan your road trip carefully and include charging stops early and often if you’re going very far.
