I got one of those new tesla semi still in alpha tho. Like and Subscribe for more original Car Pal content :) and follow on instagram for even more content :P / revvypal
@@johnxina427 LSD = Limitied Slip Differential. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WeLm7wHvdxQ.html Though, LSD here wouldn't help much. They need to manage wheelspin, LSD is meant for different problems.
There was no towing test, I'm suprised there was no test where they had to pull 10 trailers each. The tesla truck looks like it was designed for a trailer to add weight to the rear wheels to give more grip.
@@TurboDodgeXVI I mean the model in Beam. I doubt Tesla would used old style steel wheels and still have fuel tanks under the chassis, never mind that top speed which makes no sense at all for a Semi.
@@EngineeringEssentials So you are saying it is not accurate, which is exactly my point. Also according to the Tesla website it has 2 drive axles, so completely different to the model used here.
@@moodman1151 eh i mean yes i suppose but thats mainly due to the fact that they don't use traditional transmissions with 6-10 gears like ICE cars do. if you gave a tesla model s even a 4 speed transmission, i'm sure it could break some kind of world record for top speed.
@@moodman1151 Adza covered the primary issue, being the lack of a gear ratio to change the effective energy efficiency. But we have to remember that electromagnetic motors function 100% differently than ICEs. Tesla's single gear (9.734:1) definitely affects its acceleration, and would ostensibly be a factor in its top speed, but the Plaid purports a top speed in excess of 250mph. The limitations of speed in an electric, AFAIK, are predicated by the amount of energy that battery / inverter systems can be made to discharge at once. I. E. You're not gaining any speed beyond what your powerpack can provide without melting / exploding due to sheer output. I think that this limitation would change based on the final gear ratio?
@@ErikVRed right, i just explained why. Gas powered cars have lots of gears which allow their torque to be more or less available across a wider range of speeds. electric cars dont have that ability so they run out of torque at higher speeds. torque is harder to generate at really high RPM and electric motors can spin at 20,000+ rpm. if they had gears, theyd go way faster but then that also increases prices because you'd have to create a transmission that can actually handle that type of power
this reminds me of an experiment I want to do irl. Take a tesla semi, a brand new semi, and a really old semi, load their trailers with as many 1 ton weights that can fit, and then race them from new york all the way to california and see which one makes it first or breaks down last
If you want a fair comparison, all the trucks should have the chain attached to their rear axle. If the chain is attached too high on the truck, the truck's front tires leave the ground. Also, the chain on the aircraft should be attached to the nose gear. If the attachment point is too high on the aircraft, there will be a tendency to lift the truck's rear end = less traction. You want the chain to be as horizontal as possible.
about the drag race at the begginning: The gas truck took decades of research and development to evolve that far. The electric semi is literally a concept at this point, so imagine how fast it would be with as many years of existence as the gas truck.
but some one needs to state the obvious ...the tesla semi is a tandem axel (dual rear axel with super single's so 6 driven tires as its listed as 3 motor AWD ) you can tell im looking forward to it..lol
Every time I see the Tesla semi truck, it reminds me of general motors terrible subsidiary that attempted to make their own electric semi truck and when they advertised it they had it roll down a hill because it couldn't move itself under it's own weight
