18.9 kWh/17.2 kWh = 1.0988 That means you used 10% more energy not 5%. The confirmation is when you multiply 17.2 x 1.10 and get 18.9. But it's a major success to only lose 10% towing and your video is a great testimonial for the designers of that trailer and it shows you chose a great pairing for an EV. Thank you for doing this test and sharing your results.
When you started talking about the trailer, I was briefly regretting purchasing a utility trailer, which I bought mainly for camping. Then I looked up the price, and am suddenly super happy with my utility trailer purchase. 😆 In addition to costing about 90% less, it weighs only 400 labs. I decided that I wouldn't tow more than 1000 lbs with this car, so that still leaves me with 600 lbs for cargo. It can also do things like carry bicycles without buying additional parts, and haul things like plywood. I'm curious to see how your efficiency test came out compared to mine. I got about 25-30% less distance towing about 800 pounds (including bikes standing up, so not great aerodynamics), but I compared to similar speed (around 90 on average). If I compared to going 110, the difference would have been more like 15%. (my estimates are pretty rough, because I am comparing typical averages with no trailer to one specific trip with the trailer)
Thanks for your video. I don't plan to do any kind of towing when I get my 2023 Bolt EV LT2 model this spring 2023, but watched the video and it is great information you provided. I have test driven one at the dealership and really like how the vehicle performs. take care.
Great job! I don’t have a Bolt, but it’s nice to know that the trailer won’t (hopefully ) be gas guzzler. I’m going fron Texas to North Carolina to pick up mine GO so I’ll try to record gas usage just for the fun of it. Thanks for doing the interesting stuff. 😊
Very insightful video, thanks as I was looking into the Sylvan Go (both light and aerodynamic) and was wondering how it would affect a Model 3 which in the EU has the Tesla tow hitch option.
I can't over how quiet electric cars are... So cool. I wanted to get a Chevy Bolt but the towing factor played a role for me not to get it. The Volvo XC60 pure electric does have a towing capacity I believe at 3,300 pound's.
Great video, Dustin. We get our hitch next week. We're hoping to tow something a tiny bit larger. We're focused on the Aliner Scout Lite, which has a dry weight of about 1200 pounds. Fingers crossed.
Regen probably plays a huge roll in the efficiency here. More mass to expend electrons on also means more mass to recoup those electrons. You will of course always consume more overall power when towing, but that 5% margin would likely be higher without regen.
I have a 2023 Bolt EV and a Sylvan Go. I am putting on a 2" EcoHitch ECOX7359 . But I need a riser to bring it up to 17" high as required by Sylvansport. What size riser will I need to buy? Thanks Michael
Hey there, unfortunately I can't help you here. My draw tite is 1.25" and sits lower than the eco hitch. You'll need to park on a fairly level surface, level out the SylvanSport, drive up to it, and measure how much rise you'll need in your ball mount.
Gosh that was interesting and insightful. I wondered about tying a trailer in and EV. Now I know the effects of towing another energy efficient trailer. Thanks for making the video. It was very helpful!
Great video Dustin. Kinda surprising too. We have a model Y tesla on order and we will be towing a T@B 400 tear drop trailer (also on order). I don’t expect your results as it is three times as heavy as well as being 7.5 feet wide and 8 feet tall. But I’m sure we’ll figure it out. Kudos for slowing down when towing. The physics changes drastically when towing. I wish more people realized that. Find a slow RVer or truck and get in behind them. Relax and arrive alive. Subscribed. Take care.
@@DustinBatchelor I’ll try and remember to get back to you with results. We are from the Okanagan but our first major trip will be on the island. Cheers.
Great video, thank you for all your efforts. I just bought the Bolt EUV, and wasn't sure about adding a tow hitch, thanks to you, I'm adding one. Did you install your hitch? What wiring harness did you use? Did you do your test with one pedal driving on while towing?
I installed the hitch myself. The brand of the hitch is Drawtitie, and I would buy again for sure. The trailer wiring harness is completely different from the original Bolt to the new EUV. I'd suggest going to the website Etrailer.com, putting in your model of EUV, and looking at all the towing options there. And yes I always drive with a mix of one pedal driving on and off.
I bought it used in early 2020. I have a buyers guide video for the Bolt, but in terms of reliability I have had zero issues. It's been a very dependable car and I use it for all kinds of difficult things. Almost always have a mountain bike or surf board on it, I've gone on a few several thousand kilometer road trips, and it was my households only vehicle up until this August.
Amazing how little extra power it took to tow that trailer! Good to see a new vid from you. Be safe with your Bolt. They’ve been a “hot” topic as of late…
Yeah I was very surprised by the results. Thanks for watching, and I'm hoping to keep the content coming! Definitely looking forward to the new battery with the biggest capacity, but honestly I'm also on the fence of just selling it once they battery is replaced and buying something else. It's just unfortunate that I didn't budget on replacing the Bolt for another 3 or 4 years.
I towed about a living room and two bedrooms of things with my 2013 Volt from east Tennessee to Western Oregon. The car handled it fine but at like 8 mpg. Ruined my lifetime mpg which sits at 50.3...
What harness did you use for the trailer brake lights? Was it hard to install? I tried to hire a few people to install the harness but no one could. Any help I really appreciate
I bought the Tekonsha Modulite HD Protector Trailer Light Power Module (p/n 119148). It's quite the pain in the ass to do. I did do it myself following this guide drive.google.com/file/d/1OdlXkOxxJLZBquvj7EIUvjS0n4rYjMzp/view?usp=sharing
Hi! I went with a drawtite hitch and installed it myself. It was extremely easy to do with basic tools and took me about 45 minutes. The website etrailer.com is a great resource for finding towing products that fit the car. In regards to the wiring harness, that was a real pain to install. I also did it myself but I'd probably suggest that you try to get a place like U-Haul to install that.
Hey sorry for the delay in response, RUclips isn't notifying me of comments. These are the stock springs and they hold up very well. The Bolt is a heavy car and the springs are already a bit beefed up from factory. When I've had the trailer and car really loaded up I've noticed sag for sure, but it still has lots of movements.
for a small car doing tow job, EV cars with heavier weights relatively (to similar sized cars due to battery weight) actually help with towing (at some level). A similar sized car towing will probably have the MPG fold in half (50%!) to be honest
Fantastic review, thank you very much. It fits very nicely into the towing reviews of Rivian and F150 Lightning with the huge trailer. They had +50% efficiency penalty. Now, one little thing: 17.2 and 18.9 is 10% increase, right?
Thanks for the comments! Just did the math and I come out with 9%. It's been a while since I did this test and I was very tired when I did it! I used this trailer multiple times this summer and didn't notice a notable decline in range outside of that.
I'd also make the argument that with all the towing videos coming out, they should all do the route first without a trailer as your consumption will always be higher at highway speeds anyways. So perhaps that Ford lightning might have lost 25% of its range anyways going those speeds, so really it only had a 25% penalty compared to normal. Anyways, seems like the popular thing to do right now is to trash EV capability :)
@@DustinBatchelor I agree. There is another factor. These big trailers have brakes. And obviously, these are not Regen brakes. So, while yours doesn't have (doesn't need) brakes, their trailers loose lots of energy due to non-regenerative braking. That is not accounted for.
Draw-Tite Sportframe 1 1/4". If I was to do it again I probably would get the Eco Hitch, but that's just to get the 2" receiver for a larger bike rack.
Yes I installed it myself which was very easy to do. 40 minutes total without jacking the car up. Went with the Drawtite. I also did the wiring myself, although that was not nearly as fun. There's a guide a person created that I followed which I can try to find a link to if you want. Wiring is much easier on the new Bolt EUV.
Do you have an elevation profile for your trip? I would guess the uphill portion of your trip would be more negatively affected by the weight than the flat section of your trip. Someone's trip up into the Sierra Nevadas (California resident here!) could take a much larger hit than 5%, since you are basically driving uphill almost the whole way.
Thanks for the question! Unfortunately I do not have an elevation profile. I was going to have an elevation recording app running but ended up not doing it. Definitely some situations will see a much higher usage. All I can really say is that here on Vancouver Island there isn't much flat driving on the southern side, it's pretty much a constant mix of up and down.
How much does the trailer weigh? Did you add a transmission oil cooler? I would say 1000 pounds max. The car is not set up for towing with unibody frame, weak mount points thickness of steal etc. Can the shocks handle the loads the balance of the car in very important. Sure you can tow a boat with a lawn mower and any car. I bought a LR4 for towing my boat and and another car for economy. Doing both if only once in a while is ok I would not recommend with a Bolt though. Just asking for trouble. Rent a truck if its just once in a while. I tow a boat but use a 4x4 with real steal frame and drive like I have nothing behind it don't even feel it 70mph no issue. Why risk life over a tiny trailer.
It's 850lbs and is designed to be towed by almost any car on the road. Luckily no transmission on an EV (fixed gear ratio). EVs are quite heavy and therefore have a robust shock setup. I do agree it's important to make sure you are smart with what you are towing. Putting a huge boat on the back of a Bolt is a bad idea, but with minimal tongue weight and a low tow weight, the car handles it great. Another beauty thing with an EV is you have so much power available, plus you have two strong braking systems (disc brakes and the electric motor braking). I'm currently towing this with my bigger mustang Mach E as it's a faster charging car with more range :)
@@DustinBatchelor 850 pounds empty? You have to weigh it fully loaded. Are you sure there is no fluid in a Bolts Transmission. Fixed gear does not mean zero oil and zero heat. I looked it up, the fluid in a bolt is good for 150k which really means 1/2 that. If you tow often 1/2 that again. The fluid will degrade much faster under tow/heat conditions. So while its simple in moving parts he still will get hotter towing. That is why Most cars put a transmission cooler inline when they put a tow hitch on them even a Jeep. I've owned many cars since the 60s and towed boats, snowmobiles etc etc. Burned out transmission Ive been there and done that. Even own a Volt (not bolt)
@@DustinBatchelor Yea I bought a Volt they have good torque. I like the backup gas generator, I don't trust pure electric (yet). I think the perfect car is a Volt with the battery of the bolt or tesla. That back up engine is a nice to have. Too bad its discontinued. Yea you should be ok even without a transmission cooler. I would change the fluid by 100k if you keep it that long and depends on how much you tow. Its a bit more wear and tear on the entire car.

That difference between with and without the trailer (5%) is about the same as I get running AC (7%). Wild... Thanks for doing the real-world experiment.
Thanks for the comment! The car is four years old with almost 90,000km on it. I'm not very concerned that anything is going to happen with it regarding the batteries. For the most part the car is driven once or twice a week and charged every two to four weeks. It's a car and I'll use it as I need :)
I disagree with your conclusion. Your change in speed had a huge impact. 15 minutes in 2 hours is about 10%, which has a 21% impact on aerodynamic drag. To really measure efficiency you absolutely must keep the speed, and wind, the same. So, the real effect is closer to 25%.
Thanks for the comment! I stand by my results, as I will absolutely not drive the same when towing something. This is real world results in my opinion.
