No, Ford's Electric F-150 Can't Tow 1 Million Pounds (Realistically)

Motor

Ford's Electric F-150 pulled a 1 million pound train, but Ford's stunt was way easier than it looked. This isn't a competitive advantage, instead, it's a very clever, very cool, marketing exercise.
Towing a million pounds sounds impossible. On an open road, it pretty much is. On a railroad, however, things are different. With a steel wheel riding on a steel track, the rolling resistance of the train is extremely low. The result? A relatively tiny force is required to move the train in comparison to the weight of the train.
What makes it easy? Well it all comes down to the coefficient of rolling resistance. This is the ratio of force required to pull a certain rotational mass. For example, a coefficient of rolling resistance of 0.1 means you only need a 1 pound-force to move a 10 pound ball. With steel wheels on a steel track, that ratio is far, far lower. Plenty of trucks out there could have done the same thing Ford's electric F-150 did, if not family crossovers and SUVs. Check out the video for a full breakdown of how it all works.
Important Note: This video was filmed prior to my article being published in Road & Track (link below). Upon release of the article, Ford reached out with clarification. Here is additional information with regards to the power required for accelerating the 1.25 million pound train:
1. We want to know how much power it takes to move 1.25 million pounds at a speed of 4.5 mph in just 1,000 ft.
2. We’re going to assume the truck is accelerating for those entire 1,000 ft, and reaches 4.5 mph right when it crosses the 1,000 ft. line.
3. Power = Work / Time. If we calculate work & time, we determine power.
4. Time can be calculated based on average speed over 1,000 ft. Top speed 4.5 mph, starting at 0 mph. Average 2.25 mph. 2.25 mph = 3.3 ft/s. 1000 ft / 3.3 ft/s = 303 seconds (5 minutes, 3 seconds, to go from 0 to 4.5 mph). T = 303 sec.
5. Work = change in kinetic energy. We start at 0, so kinetic energy is zero. All we need to know is final kinetic energy. Kinetic energy is equal to one-half mass times velocity squared (k=0.5mv^2). 12.5M lb = 566,990 kg. 4.5 mph = 2.01 m/s. KE = (0.5)*(566,990 kg)*(2.01168 m/s)^2 = 1,147,263.561 N-m.
6. Plug in variables to Power equation. Power = Work/Time. P = (1,147,263.561 N-m)/(303 seconds) = 3.786 kW or ~ 5 Horsepower.
7. It’s important to note that 5 HP is the power required to to accelerate this mass assuming zero losses. Heat, friction, aerodynamics, etc. There are also smaller assumptions like not accelerating any rotational masses (the train has wheels, etc). A sanity check using the same math shows a 3,300 lb car requires 240 HP to go 0-60 in 3.0 seconds. We know it’s generally double that in the real world. Even giving the truck a factor of 10 advantage, 50 HP is nothing crazy.
8. The train is very heavy, this is the impressive part. Unfortunately, the duration is very long (5 minutes), and the speed is very low (5 mph). Both time and speed variables work heavily against the power required. If the train were to accelerate to 60 mph in the same 1,000 ft distance, it would take 12,000 HP without losses. Quite a difference, just from changing speed!

    **IMPORTANT NOTE** This video was filmed prior to my article being published in Road & Track (link below). Upon release of the article, Ford reached out with additional information.

    That the strap had stretch to it was very important, if they hd used a chain with no stretch, then for the first foot or so the motor, while able to provide the required torque, would be barley spinning, and so would not be cooling itself and might overhear. It appeared to me that the strap stretched about 8 feet or so, during that time/distance the pulling force went from 0 to 5000 pounds, all the while the truck was moving and therefore the motor spinning and cooling itself while the boxcars accelerated from 0 to maybe 1/2 mph as it the first few feet. In this case, as opposed to yanking a stuck vehicle out of a ditch, it was important that the pulling truck apply an increasing pull from 2000 to 5000 over a significant time/distance. The same feat could be done with a truck with an automatic transmission, but may meed a double sized transmission oil cooler. It would be near impossible to do with a manual transmission truck unless the tow strap were ten times longer and had twice the stretch ratio.

    I can't remember the exact details but, 10 years ago, in the state of NC, I had a friend who worked in a prominent oil change facility. He told me that it was illegal to show a customer their own engine oil, on a white surface, compared to new oil. Something about deceptive sales practices. This Ford commercial seems to be doing the same. It should be illegal to show pickup trucks pulling train cars.

    It’s not the slip it’s the fact that the steel doesn’t deform as much, reducing the rolling resistance, the locomotives that haul miles of those cars have steel wheels, and you don’t want any slip on the locomotive, it’s entirely rolling resistance.
