Tesla set an example where range in its semi under full load decreases from 620 empty to 500 miles under full load. That is a 20% reduction in range. But ICE reduces 50% on top of its already horrible comparative efficiency. Top Cybertruck being made out of the same components as the Tesla semi will quite plausibly also reduce range under full load by a factor of 20% or from 500 miles to 400 miles where its closest competitor the Ford Raptor is at about 288 miles.
But Tesla has yet to add recuperative braking, PV and better aero to its trailers. Right now about half the weight of the Tesla semi tractor is likely batteries and motors or power train. But the power density will continue to increase at about 15% per year up through 2050 in lithium even as lithium its theoretical limit has about half the power density gasoline. Even so in less than 5 years range on lithium alone without adjustments to trailer (recuperative braking, pv cells, aero, lighter construction materials like 30x) will match the farthest running class 8s but with the other enhancement exceed them. The cost per mile for he semi is already half what it is for diesels and it will continue to drop.
Its also a lot more convenient to have some charge stations than having to rely on having fuel delivered to a yard fuel station a business must pay to maintain. Having roof top batteries and PV at a yard is even better in terms of savings.
The Cybertruck seems to herald this difference right now. Raptor will only haul about less than half the total weight and will need to refuel at 288 miles vice 400 miles and at a rate of 8mpg vs about 67mpg under full load.- and again this is where Cybertruck is carrying 2.15x as much. You'd have to make 2.15 trips in the Raptor to carry the same amount. The Cybertruck unloaded is about 83 eMPG and 67 eMPG (guesses) so under full load of 17500lbs (vs Raptore 8150lbs) its more efficient than a Prius by a huge amount. To really hammer this home, a fully loaded Tesla semi will carry 10x what a fully loaded Raptor does for half for 1/4 cost per mile or half the cost per mile of an empty Raptor and it will go 212 miles more before needing a quick 30 min recharge- its 40x more efficient than a Raptor under load- even the Cybertruck is like 18x more efficient and takes 2.15x the load 38% further .
And the Raptor lacks some convenience in that it can't refuel at home and will start trips requiring a trip to the gas station and may well end trips requiring a trip to a service station- not necessarily the case with the Cybertruck. Of course superchargers aren't as prevalent and need some modifications. But a mega charger possibly the (+) in 250v+ for Cybertruck could likely charge a Cybertruck to full in 12 minutes.
