Yes, there are a lot of electric vehicles on the market which can tow a trailer, but keep in mind that not only may the towing capacity be different, but the handling characteristics whilst towing may also feel unusual if you are used to a diesel-powered SUV.
Over the past few years, as prices have reduced, government grants have gotten more generous, and EVs have gotten more capable, many business owners have considered making the switch to a powerful electric SUV to take advantage of lower running costs.
However, whilst beneficial for car fleets, transportation and commutes, one question that we are increasingly asked whilst servicing and repairing trailers is whether an EV is a good towing vehicle.
As long as you choose the right one, understand the advantages and disadvantages, and know the tips and tricks to make the most of your new electric towing vehicle, you will not have too many issues towing with an EV.
Can All Electric Cars Tow Trailers?
Unlike petrol and diesel cars, where the vast majority can tow at least a small trailer, the complicated drivetrains many modern EVs have are not necessarily suitable for towing heavy additional loads.
As with any other car, you can only use it to tow trailers if the latter is lower than the former’s rated towing capacity.
This will be found in your vehicle’s log book (V5C), but model information is also available online if you need it. Some EVs have a towing capacity of zero.
Why Are Some EVs Unsuitable For Towing Trailers?
- Their operating range is too low with a trailer attached.
- The weight of the battery pack is compounded by an additional heavy load.
- The regenerative braking system is difficult to manage whilst using a trailer.
- Some EV models are not designed to tow at all and lack anywhere to fit a towbar.
Why Use An EV To Tow A Trailer?
Much of the above may look like a major red flag, but there are some significant advantages to using an EV as your towing car rather than a typical diesel estate or 4×4. If you make the right choice, an EV can even be a better choice whilst driving.
Here are some of the biggest benefits of using an EV to tow a trailer.
Instant Power Delivery
EVs have astonishing levels of torque, which allows them to accelerate quickly, but also gives them additional power and force to move heavy trailers.
Unlike a petrol or diesel car, EVs can almost immediately deliver their full power, making them ideal for managing heavier trailers, climbing steep hills and safely navigating motorways without losing control.
Quieter Towing
One of the bigger frustrations of towing is the noise an engine makes when it manages the strain of a heavy trailer.
Whilst EVs will still make noise whilst towing vehicles, it is much quieter and provides a little more peace during a drive that is inherently rather stressful.
Regenerative Braking
EVs have incredible braking power because a lot of the heat and forces from braking are captured by heat and kinetic energy recovery systems that provide your car with extra energy and range.
Whilst this can take some getting used to, it also means you do not have to worry about brake fade with your towing vehicle in the same way you might with a petrol or diesel car.
Zero Emissions
If you are running a greener business, the easiest place to start is with your fleet. EVs generate no exhaust emissions regardless of how heavy the trailer is.
Low Centre Of Gravity
EVs are heavier than diesel cars, but where that goes from a drawback to a strength is where this weight is located. EV battery packs are on the floor of the car, providing a low centre of gravity which significantly improves traction and avoids the effects of buffeting.
Will Towing A Trailer Affect Your EV’s Range?
Yes, it will, and the range reduction can at times be significant. In total, a realistic range reduction is between 30 per cent and 50 per cent of your typical range, and this can radically affect how you organise your journeys with a trailer.
The reason for this is twofold: not only do you have additional weight, but EVs rely on minimising aerodynamic drag to increase range, something that is far less possible with a trailer.
Top Tips For Making The Most Of An Electric Trailer
- Choose a bigger EV than you think you will need; a larger EV with a bigger motor and battery will handle a trailer with less strain.
- Know where your local charging stations are and err on the side of caution when charging.
- Check your battery temperature, as the extra load puts additional strain on your battery, lowering capacity and increasing charging times.
- Make sure your EV of choice has the towing package fitted, as not every model in the range may have towing capability.
- Ensure that your insurance covers EV towing.
