Battle of the e semis

Nikola vs Tesla.

Nikola- fuel cell, battery buffer, 6 motor all wheel drive, no diffs, independent suspension.

Tesla- Basically, a big ass version of an electric car. A few bazillion batteries and a big motor or two. Not sure if they use diffs or not.

I watched an hour long video put out by Nikola. I was quite impressed. They had their fully independent suspension done by the company that does the suspensions for the latest generation of military heavy trucks. Some pretty impressive stuff.

A nice feature of the Nikola is that GPS can know when hills are coming up. If it is a long downhill, it can run the battery pack down some so that it will take full advantage of regen. With the Tesla, you start with a full pack. If you have a substantial downhill run on the full battery, there is no place to put regened power.

Independent AWD is definitely an advantage especially in places where traction/roads aren't so good. I like the idea of a decent sized battery pack that is never run down too low. You can get a lot of life out of these things if you aren't running them into the ground. No diffs=better efficiency and less stuff to break.

The question that remains is can they put together the necessary H2 infrastructure. Can such a large fuel cell work reliably? Can it be built at a reasonable price?

As for the Tesla, we shall see. I still have one unanswered question. Is there enough lithium out there to build literally billions, if not trillions of batteries.

My feeling is that the fuel cell/battery buffer idea is a good one IF it proves financially feasible. If not, earlier versions of the Nikola using natural gas turbines might work. Turbines have a long history of use, we have lots of LNG and an existing infrastructure and they are greener than a diesel generator, which is something also worth looking at.

Tesla has 4 motors and no diffs, and also has independent AWD.

EDIT: What pricepoint is Nikola aiming for? Tesla's release stated 150k, vs ~120k for a diesel.

The Tesla is not AWD. It's steer axle is not driven. The Nikola is. Wasn't aware the Tesla was full independent. They were making a big deal about it, so I figured the Tesla wasn't.

Not really sure if the driven front axle is a benefit at all. Might actually degrade steering feel.

It may depend on how evolvable the respective technology bases are. Improving battery and charger technology vs metallic hydrogen storage.

The difference between science and screwin' around, is writing it down.
