I can't give you any of the numbers. But I can assure you that this vehicle was sized for the job.What would the electricity requirement to propel a 80,000 pound vehicle up a 5% grade for 5 miles?
I've heard gas turbines become less efficient the larger they get
I just have serious doubts 400 KW would be enough to do the job of driving the vehicle up a mountain while weighing 80,000 pounds
Exactly. The peak power of the truck is actually 1.5 Megawatts. With the turbine running, the battery can supply the other 1.1Megawatts. Of course as you drive this way, the battery SOC starts to drop. But there isn't a hill in the country long enough to deplete the batteries. And then of course you regen down the other side. With 80,000 lbs, regen starts to be a lot more significant.Gas turbines become MORE efficient as they get larger
and 400Kw is 533Hp -
Some (only a few) of today's truck engines exceed 600hp - BUT they only achieve that power at maximum rpm
Using an electric drive this truck would have 400Kw available all of time + being able to pull from the battery
I found it interesting that there is no real audio - just added music. Does the gear whine sound that bad?Nikola One in Motion - "Behold, the 1,000 HP, zero emission Nikola One semi-truck in motion. Get ready for the pre-production units to hit fleets next year in 2019 for testing. The Nikola hydrogen electric trucks will take on any semi-truck and outperform them in every category; weight, acceleration, stopping, safety and features - all with a 500-1,000 mile range!"
Ah, yes... the classic announcement-of-an-announcement to keep the stock value up.Another big announcement due...
Faked. This truck has never driven and probably never will. I'm guessing they had a pusher that they photoshopped out (which is pretty easy to do these days).Nikola One in Motion - "Behold, the 1,000 HP, zero emission Nikola One semi-truck in motion.

Hybrids provide their greatest advantage in urban stop-and-go situations; long-haul trucks are the opposite situation. There are short-haul hybrids; they don't make sufficient economic sense to be successful in the market, yet.Considering that hybrid drivetrains have been around for cars and locomotives for more than a decade, you would think all the current truck builders would have them.
That's extraordinarily simplistic, and makes no sense. Companies buy trucks to do a job effectively, at minimum cost. Fuel consumption is part of both effectiveness (higher consumption means shorter range and/or less payload) and cost (obviously). Go ahead and build a truck which is cost-effective and uses less fuel; I assume you have billions of dollars for development.Makes me think the point of their vehicles is oil consumption, not transportation.
At least we agree that this design makes little if any technical sense, given the reality of the source of hydrogen. The natural gas turbine hybrid is Wrightspeed's design; they have targeted entirely different truck applications so far, where the technology makes more sense.This Nikola machine is just a thinly veiled attempt to create a natural gas consumption machine (via H2 reformation). They would consume less NG if they just build a hybrid drivetrain with a gas turbine genset.
