You realize that electric engines do not have the torque limitations that gasoline and worse yet diesel engines do. If you want torque, you definitely go electric.

Yes, electric motors do.
https://www.electrical4u.net/calcul...n be found from the motor’s nameplate details.
You also have to account for Counter Electromotive Force.
So, while electric motors generally have more torque, that doesn't equate to unlimited torque.
Diesels have more torque than gasoline engines. Why do you think large trucks and trains run diesel engines over gasoline?
I'm not arguing electric motors have more torque, they do. What happens when you run out of battery and there's no charging station anywhere near you?

They drove an elect Ford truck all the way to Prudhoe Bay Alaska. It was a nightmare to charge. They even had to charge it off of the hybrid truck they brought along.

Walt which would you rather have to tow a 6,000 lb trailer 800 miles. A Ford Lightning or a Ford F250 diesel.
Were the cold temps a factor with the charging issues?

No but he said in the winter it would have been a problem. The lack of charging stations was their biggest problem.

The best way to simply judge torque is by acceleration. Diesel engines have a major problem with acceleration, while electric motors need to have regulators to keep from liquifying the tires.
There has not been a train propelled by diesel made in decades. Most of the world uses electric trains to transport cargo. They use overhead wires to feed electricity, so they get all the good from an electric motor with no need to carry the fuel. Electrifying a line costs more money, but the investment more than pays for itself in a decade.
The US underinvests in infrastructure, so we are stuck with diesel electric. It still uses electric to propel the train; no sane person would try to tow 5,000 tons over a hill using a diesel engine. It uses a diesel generator to supply the electricity to the electric motor that propels the train. It is wasteful to have to use two engines, but batteries are not there yet, and diesel will never be good at propelling trains.
The nice thing about electricity is that it is by definition source agnostic. You can power electric via diesel, solar, wind, nuclear, gas, etc. Our entire society is built around electricity being the central, interchangeable energy.
Meanwhile to power a diesel engine, you need diesel... AND THAT IS IT!!! There is no substitute.
Not only does electric motors have generally more torque than diesel, when they have slippage it almost never destroys the motor. Diesel engines can completely be wiped out by slippage.
If I am trying to merge onto a highway, and you are puttering along dangerously in a truck too big for you to drive safely, which type of vehicle would I want to blow past you, and leave you as a distant dangerous memory? Obviously electric has the acceleration that can do that for me.
There is a reason they try not to use diesel in arctic conditions. Diesel begins becoming sticky. At least with electric it is easy to keep everything warm. Warming up the diesel is a pain in the neck.
Honestly the best fuel for cold conditions is jet fuel. Heavy diesel is a mistake.

If diesels are so poor in cold conditions, why did Toyota's engineers and others associated with the Top Gear drive to the North Pole use Toyota Hilux diesel pickups? Why did Toyota then use them again to drive across Antarctica?
Walt is retarded. He knows nothing about trains, trucks or what cold conditions do to electric vehicles.
If they had used diesel, they would have died. They used jet fuel.

It was all pioneered in Iceland. They modify the trucks to use jet fuel, and never, under any circumstances, shut off the engine.
It is worse than I thought. The gel point of diesel is 17.5ºF. That means at 17.5ºF diesel stop working in engines. You can add additives that will change the gel point by a few degrees, but not as much as you would think. Basically, by the time you reach zero degrees Fahrenheit, you need a heater to keep the fuel warm. That heater is usually ELECTRIC.
Meanwhile, electricity is not bothered by the cold. Batteries are, but batteries create their own heat, so many times insulation is the solution.
Back to Antartica, where the temperatures regularly get down to -60ºF... You are not going to get a diesel engine working there.
Almost every satellite has a battery, and electricity.... That is -455ºF.
So, if a diesel engine does not work there, what form of powered truck delivers their supplies?
Satellites? Who the hell brought them into this discussion?
If you are just talking about the Canadian tundra, you will generally use an electric heater to keep the diesel warm enough to use. If you are talking about Antartica, you need a truck that can run on jet fuel.
Space is the coldest conditions possible. It is about absolute zero, which is to say it is impossible to get colder. And yet almost everything we send into space runs on electricity. There is no point to a satellite without electrical power. While diesel has massive trouble working in just cold weather, electric is working in the coldest temperatures possible.
Indeed.

Antarctic stations and logistics rely on the use of fuel.
Diesel fuel is used to make water, generate power for light and heating, run vehicles, aircraft and camp stoves. Although we are implementing renewable energy options, particularly at Mawson with the wind turbines and hydrogen demonstration project, we still rely heavily on fossil fuels.

Walter has not been right this century.
Jet fuel is kerosene. A jet engine will run on diesel fuel, a diesel engine can run on kerosene (jet fuel), although it should have a lubricant added (motor oil is generally used because kerosene has little lubricating qualities).
