@kevinchadwick8993 torque at the wheel falls away in a gas car with every gear shift....torque is reduced in EV at highway speed, which is a consequence of power being pretty constant(torque = power/rpm) power tapers off when you get closer to top speed, which people usually don't do on public roads.
the difference is torque reduces smoothly whereas gas cars get sudden drop when switching gear
the thing is for comparable vehicles, EV simply have more power, at any speeds that people actually do (lets say under speeds that will get your license removed instantly or get you to court like 30mph over limits / 100+mph), because its easy to add more power in an AWD EV, with little to no effect on range. in gas cars, power is always a compromise between performance, gas mileage, reliability, engine size/weight
bolt is almost the cheapest ev you can buy and 200hp 6.5s, compared to lets say a honda fit 130hp 10s
every EV in AWD version is like 300/400hp + and sporty versions like inoiq 5 N/kia GT6, the new tesla M3P, or even a f150 lightning, silverado EV are in 600hp territory
if you compare them at highway speeds, they will still have a ton more power than gas equivalents

this is a way more important vehicle for Tesla than cyber truck at global level.
it won't be 25k though because people will be ok to pay more, I don't see less than 30k, actually not likely less than 35k until they can make literally millionS of them per year. if they can sell model Y starting at 66k and 3 RWD starting at 57k like hotcake. Corolla hatchback/Camry/RAV4 in similar SE trim msrp are 23/27.5/33k so following the same kind of pricing structure it would even be around 45k. could be less if they really cut down on features and range but it's not going to happen until they cover all the demand for higher trims but I don't see why they wouldn't want to keep premium prices and premium features that make them both profitable and desirable.
Cyber truck is strategic in the US because it will compete with the best selling vehicle, F150 & 150 lightning, it's more the manufacturing technique. if they can figure out the way to make them cheaply and massively, it could enable a whole line of value crossover/SUVs spin offs cheaper than Y/X using similar manufacturing that could sell like crazy too. if Tesla can keep going against the automotive trend of facelifts/restylings every 3/6 years and planned obsolescence which involves redesigning and leads to over styling the designs to differentiate vs previous gens, and keep rolling out incremental improvements/adjustments without stopping production, plus software updates to the existing cars, it's win/win, people want the cars, Tesla doesn't need to be continuously risking to reinvent existing designs. they can make long lasting cars that people will want to keep for a while, and that will still hold a good value after year.
their biggest risk of losing the.EV grow are
1 if China manages to produce way more cars and to export them.
2 if disruptive battery tech like solid state leaves them with expensive investments in battery factories, and they fall behind the curve on parents, R & D etc. if/when self driving is widely accepted, having the edge on software and infotainment could continue to maintain their headstart but I think they will have more competition on software by big software companies who already have the app stores and the experience

I would bet a healthy amount of money that the roadster will NOT have 600miles of range in any version. not because it's physically impossible but because if it did it would just be a totally inferior product. the only use would be Autobahn or cannon ball 120 -150mph cruising but this would . 600 miles of range isn't even that desirable for a family car but it. would just make more sense in a model s "GT" plaid+ powertrain, no track package/aero, active suspension. no focus on track performance, just power, range, comfort, like AMG S class.
you don't sacrifice hundreds of pounds in an electric super/hypercar for range. the biggest single performance bottleneck in current high performance EV like S plaid, Rimac nevera, taycan turbo GT is weight and how weight impacts tires performance. no current road tire technology is able to withstand sustained acceleration, braking and cornering at high speeds, which is what super/hypercard are meant for. owners of these lmkind of car spend a lot on options to save weight
Making an EV that can beat any gas car on any performance metric is a great objective, and range is not one of those metrics. I don't know. if it can be achieved with 2025/2026 battery tech, not with current tesla energy density focused battery tech, and not with upcoming iterations of 4680 cells
also not without full carbon tub and body
the trend in very high performance EV/PHEV (nevera, Evijah, Gemera, future Bugatti hybrid) is very high electric output with a smallish battery optimized for power density. if Tesla keeps prioritizing range the roadster will be a failure
regarding the spacex package ability to to 0-60mph in 1s I think it's possible but with a huge compromise on range, weight and efficiency, also impact on performance when the thrusters are not used. I don't think they want to enter a mass production process for these thrusters/compressors/big pressure lines/tank. what makes sense is to just make enough spaceX roadster for influencers and high profile personalities like they did with the first deliveries of the founders cybertruck. it's a car for exotic cars drag racing channels, jay leno, etc. I'm pretty sure they won't be able to meet the demand.

@shawncooper8131 not really that big of a problem considering the actual number of battery replacements.
"the average time a person owns their first car is 4.2 years. The average number of miles driven in a first car is 43,000"
meaning most will sell long before 8y/100k miles
if you wanna keep your EV until it dies, just follow recommandations, charging daily to 80%, your battery can last much longer.
hopefully by the time all those EVs get close to the end of warranty, dealerships will be able to make accurate diagnostics of battery health, not only through recurrent but also their own diagnostic tools,and to offer relatively affordable battery warranty extensions
yes battery replacement are expensive, but engine/transmissions are expensive too, and people still buy high mileage gas cars. the big advantage is that determining a battery health is easier, less labor intensive than an engine. I can. see EV battery diagnostics becoming very common, whereas compression tests, lab analysis of used oil, or full engine disassembly are very rare and only for niche car markets. if a used EV loses most of its value because of uncertainty about the battery health, the brighter side is that a. lot of money can be made by restoring customers trust and/or offering warranties

chillfluencer nope, most manufacturers already waste capacity on the batteries by implementing buffers below 0% and above 100% to make the batteries fool proof. when your manufacturer says your engine is good for lets say 200hp or top speed is 130mph, do you think you can drive for hours at top speed/full throttle/near the redline and you will always get the max horsepower at any temperature/elevation? no unless it's a race car
Could they limit the rpm and horsepower to half their maximum? yes
Would you want it? no
Battery is the same, you can trickle charge between 20-80% most of the time which would be the equivalent of cruising at legal speed in top gear for an engine (will last hundreds thousands of miles with proper oil changes) and you can charge it to 100% before a long trip, empty it to 0%, fast charge it etc when needed like you would take an engine at full throttle through the gears, to the redline. It's designed to do it, just not all the time. You know it's wearing quicker when you do it so it's up to you, and most importantly you don't NEED to do it. On the other hand, you can floor your EV most of the time with little effect on its lifespan, except on the tires.

@wongcw08 you also always have the funny comments about EV "taking 3 hours to charge/ taking 10 hours to do a 3 hours drive", being "quick but not fast", "always slower than gas car in roll race", "run out of power at highway speeds", "spontaneously catch fire", or and get bricked when they go down to 0%, Oh I forgot they are so heavy that they destroy the roads and are more dangerous because of all the rubber particles they produce
0% facts but somehow people think repeating something wrong makes them look smart 🤓🤓
Which is funny because evs still have a few disadvantages compared to ICE, they are simply not nearly as serious as they used to be.
EVs with NACS connectors, superchargers opening up , new competitive models priced right like volvo EX30, kia EV9, going to trigger another wave of EVs
The next wave will be tesla 25k car, end other EV really competing with mainstream affordable cars like corolla, civic

they use only one permanent magnet motor in the front for cruising more efficiently. induction motor dont have a lot of drag when they are not excited, so its ok to let them engaged but not require a clutch( or clutches).
For the Semi its a bit different because it has a giant, super expensive 900kWh battery. even if the clutch only saves 5% when cruising, boecause semis spend most of the time cruising, thats potentially a 50kWh saving, thats a significant cost and weigh to be saved.
I thought the cybertruck might use clutches too, but I think with induction motor(s) its probably not worth it. its a compromise beetween cost, weight, complexity, reliability, etc.
If you add a clutch, you might as well add another gear ratio and a secon clutch and make a 2 speed DCT like on the taycan, but again, it's usually not worth it on an EV because of the torque transmission and clutches have to be overbuilt. remeber the first gen roadster that was breaking gearboxes like crazy
