Ford Lightning Towing Test Shows Serious Problems

The Lightning isn’t any better than the Mach-E…when will we stop trying to deceive customers?

From Motorious:

It didn’t do well going up against a gas-burning GMC Sierra…

With the advent of all-electric, full-size trucks on the market there’s been a lot of debate on social media and even among friends in real life about the benefits of such a vehicle. People can get very emotional and heated defending their viewpoint on whether having a traditional ICE truck or one with electric motors is better. Instead of just debating this, YouTube channel The Fast Lane Truck decided to set up an interesting test.

We’ve seen other automotive media outlets do their own tests between electric and traditional pickup trucks recently, but they’re mostly disappointing. After all, we firmly believe trucks weren’t just made to look cool while you cruise around town. Yet these tests have focused on drag races, 0-60 acceleration, and other nonsense. You buy a truck primarily to do truck things: towing and hauling.

Fortunately, The Fast Lane Truck gets that, so they decided to hitch an empty car carrier to a new GMC Sierra Denali Ultimate Edition and a Ford F-150 Lightning to see how they handled towing a load over long distances. The results were incredibly revealing, exposing one of the biggest doubts we’ve had about all-electric trucks and their real-world usefulness for doing truck things.

The whole point was to see which would happen first: the Sierra runs out of fuel or the Lightning’s batteries go dead. Now, we’ve known far too many EV enthusiasts who get all smug about range anxiety and how people need to just calm down because nobody needs the ranges they think they do. Well, that’s true if you only drive in the city and mostly commute. However, there are people who go out on the open road, hauling trailers in the wide open Western US where distances between cities often exceeds what your electric car can do on a single charge.

But Ford has been boasting about how with the larger chassis in the F-150 Lightning, it has that much more juice so you can really go out there and not have to worry about running the battery dry. Well, The Fast Lane Truck debunked that claim, at least when towing a trailer is involved. The Ford truck didn’t make it the 282 miles the onboard computer estimated, a figure which was adjusted to 160 miles once the driver provided the trailer specs. The plan was to go to a charging station 147 miles away, but as the batteries depleted more rapidly than expected, a destination 45 miles closer was chosen. However, the Lightning couldn’t even make it the 102 miles pulling the trailer, so the driver had to turn around and head back to a nearer charging station, arriving with 9 percent charge left.

To the SRD’d LL6…

Your analysis is spot on! I’ve told people that a Lightning EV F150 could only get similar towing range and performance as a gasoline version with a 300kW battery pack. If that could even be done you would be looking at a price increase of $35k to $45k range (at current battery prices).

I tow a 31’ travel trailer that weighs approx. 9000lbs loaded. A Lightning EV F150 towing that is Laughable.

Thanks @tvl+1hGqsxtn !!! I shared your post with friends who were under the illusion they could pull a large camper to remote UP areas with f150 BEV, use the F150 bev batteries to power the camper while boondocking for a week and then return. My napkin math showed not remotely possible unless they had an alternate power source, but hey they saw a commercial that implied otherwise.

Nice approach to energy equivalency. Next would be temperature curves and its effect on battery capacity and output as well as auxiliary components that draw additional power in an ICE only.

I am happily retired and was a sadly SRD LL6 TE. I used to be good at conducting quick estimations for decision making purpose. For folks interested in this type of posts, you might find this useful if you enjoy more insights.

The EV range related math can be very simple. A gallon of gas = 33.4 kwh. A f150 BEV 130 kwh battery is about the same as a 4 gallons tank in available energy.

Typical 4x4 light truck FE is 18/22 MPG. F150 BEV MPGe is 61/76. The FE ratio of EV/ICE is about 3.5 highway. For a same amount of energy given at pump, F150 BEV is 3x more efficient.

With that, F150 BEV is equivalently a F150 ICE with a 4.*3.5=12 gal tank, vs a GM 24 gallon tank, 50% smaller. Therefore the F150 BEV range must be lower by about 50%.
It is expected that while F150 BEV needs recharge but GM (or other similar ICE LT) should be able to run w/o a refuel. No surprise here.

The accurate highway range estimation is impossible. Basically you cannot predict the "future" headwind accurately, while road loads corresponding to the vehicle speed is the dominant factor in highway energy consumption.

With the well known traction power equation, we notice that the F150 BEV frontal area with trailer is about 16 m^2 vs roughly 3 m^2 w/o trailer and total weight doubled with trailer. Let's just ignore the details and look at the end results. The truck-only EPA range, 300 miles, dropped to about 90 miles with trailer & highway-only, 30% of the FE label. No surprise here either. (combined City & Highway is around 130 miles, closer to 160)

I cannot detect any possibility for the specific truck-trailer combination to reach anything closed to 160 miles range. There must be some software issues/assumptions that estimated 160 miles at startup with a full charge. Please note forecast is never easy. For example, if the range estimation is based on the average driving pattern of prior X-X miles, the estimation must correct itself after the trip starts.

These calculations can be completed within seconds.

Anyone that tows regularly and buys an EV truck needs their head examined.

I’m far more interested to see how it does against the E Silverado. I’m guessing not good because GM’s is a dedicated BEV platform where the Lightning is just the ICE vehicle with a battery stuffed inside.

(Continued)

With a 24-gallon tank in the Sierra, it had a much longer range. Like with the Ford, the computer estimates range with the trailer specs, pegging it at 264 miles. Unlike with the Lightning, the GMC did just fine on range, although when its rival turned around it just headed back to the starting point without stopping to refuel.

Another important problem with all-electric trucks, one we admittedly didn’t even think about, was exposed during this test. Charging one with a trailer hitched up isn’t exactly easy since most public chargers are set up in a regular parking stall. The Fast Lane Truck had to park the truck and trailer across multiple charging station spots to plug in the Ford Lightning. Perhaps having pull-through chargers like how gas pumps are set up would be a good idea in more places?

This test exposes the fact that EV technology isn’t ready to fully replace internal combustion engines, no matter how badly EV advocates want to see that happen rapidly. While the tech has come a long way, it still has a lot further to go.
