And we thought diesels had torque

Just saw an article on a pretty cool publicity stunt that Ford has pulled. They have a video of an electric F-150 pulling 1,000,000 pounds.

https://youtu.be/bXFHgoon7lg

While a stunt, it is true that electric motors have astonishing amounts of torque. The world is about to change.

Cheers,
John

P.S. They didnít mention what hitch was used.

Electric vs. Diesel

The biggest difference between torque produced by electric and diesel motors is that with electric the torque is immediately available while with diesel it increases with RPMís. Chart follows.

John

I would imagine that diesel would be able to pull heavy loads for a much longer period of time. Electric, I would be curious about Time it takes to charge fully and how load changes your range. Iíll be the first one to go electric once charging is reasonable and readily accessible

I'm right there with you. I have a deposit on a Rivian. It has 10,000 ft-lbs of torque! There are lots of chargers were we usually travel, but finding one to accommodate a truck with trailer is going to be a challenge. I'm really hoping we can see at least 200 miles of range towing.

The main problem with these electric Vehicles is the amount of fossil fuels burned to produce the electricity to charge them causes more pollution than just burning the fuel in the vehicle.
Converting coal into steam, into AC electricity, into DC electricity there is a loss.
I’m all for it and hope one one they can get the charging and range figured out but, we are not there yet.

I have heard this before and is mostly false. Depending on where you live, much of your electricity from the grid may already be from renewable sources. In addition, many people with EVs can put solar panels on their house and charge 100% of their miles from the sun. No one can say that with ICE vehicles. Even if 100% of your power came from coal power, the power plant is likely more efficient and maybe even cleaner burning than your vehicle.

Agree, but your going to start a whole bunch of static when you tell folks that! And then there is the age old question of disposing of the depleted batteries when you change vehicles or replace the batteries... From what I have read, the "load" will quickly deplete the charge; not sure I would consider going on a trip with my Airstream having to stop every 100-200 miles for a charge...so now your talking about larger batteries, and perhaps even renting two electric camp sites; one for your RV and one for your TV! Nothing wrong with the forward thinkers, I'm just not there yet! 400 miles between fill ups and having fuel stations most everywhere we travel makes the trip much less stressful...but that's just my thinking.

Anybody able to add steam engine data to the graph?

Steam ruled for a long time.

Max torque at stall all you gotta to appreciate the power of steam is add an antique steam tractor pull to your list for 2019.

Thatís not a problem at all. The cost per watt hour is all that matters. The power plant is already running anyway.

A diesel or gas engine produces no torque or power at zero rpm. An electric motor does. That’s the trick.

That chart has no information. The scales are labeled "Low" and "High". No source.

Utterly meaningless.

Yes, I'm aware that electric motors have high torque right off the bat, while internal combustion engines have to buildup speed. External combustion engines (steam) too for that matter.

My point is that a graph without the scales labeled and the data sourced doesn't mean anything. You may as well pull out your Crayolas and put some squiggles on a piece of paper. Who knows, maybe that's how that graph was done.

Battery production

It's not just the production of electricity that's dirty, but the manufacturing of all those batteries is extremely unfriendly to the environment.

Everything pollutes. Cost per mile is what I care about.

PS I tow with a diesel
