@Kultsholy shit that's ugly as fuck, that motherfucker better come with a steering column that sucks your dick for you, and drives for you while it's doing it. Even then I'm not sure it's enough to excuse that design. This nigga smoked a blunt on the Rogan podcast and must have lost all his senses.

 

That might even look futuristic if it were 1978, but it reminds me of a shittier version of the original Lambo SUV fail. You know everyone associated with that truck, the engineers, the designers, etc are fucking embarrassed. Anyone see the "armored glass" fail during the live Demo. Damn, this is a dark time for Tesla fans. I can't imagine a situation where it's socially acceptable to pull up in that thing, unless you're already on the moon, or mars.

How you guys feeling about this one? Why cant they just make EVs look like regular cars? Personally I think it looks miles better than the CybrTrKK but it still looks dopey as hell. Why give an electric SUV the mustang badging too? What the hell is that..

I probably am not qualified to talk about this because i'm not an EE, but wouldn't a transmission with multiple gears potentially extend the range of one of these engines by allowing it to operate at a lower RPM when at a higher speed?

I have no idea if that’s how electrical engines work. Are batteries measured in rpm? 
 

I see what you’re saying but golf carts and Tesla don’t have gears either. 
 

just one large power band.

Not sure why they call that hideous piece of trash a truck exactly. But if i had the scratch I’d wait for a real one. Saw something rad somewhere on the internets, cant remember where but I’ll try to find it.

True.  Batteries are measured in "amp hours".... which essentially says "how long can it discharge this much power".  The thing that makes this confusing for me is, and hopefully someone can explain this.... actually I'll ask my friend and come back and explain it to all of us.....

 

If it takes 200 amp hours to run an motor at 5rpm.

If it takes 600 amp hours to run a motor at 10rpm.

If @ 1rpm the vehicle travels at 1mph and at 10rpm it travels at 1mph w/o gearing.....

couldn't you run it in a "higher gear" at 5rpm and get 15mph out of it and only consume 200 amp hours worth of battery?

 

That's why this is confusing to me.

Rivian is probably what you're talking about.

And yeah.... I recently got a 8' bed 12 valve dodge cummins (mechanical diesel, ie. no electronic fuel pump/fuel injectors or computer controlled fuckery)..... it's a real truck that can do real truck type shit, and still maintain a giant range with 35 gallon fuel tank.  The 8' bed makes it a "long bed" and that means my full size dirt bikes fit in the back of the truck without having the tail gate down, and there's still room for all kinds of other shit.  It can also pull a 5th wheel trailer which is the kind that uses a gooseneck and attaches into the middle of the truck bed rather than at the rear bumper.  This is the kind of trailer that not only weighs a fuck load by itself, but you can load like 6 cars on and the pickup truck can still pull it up hills and everything.

 

We won't see an electric vehicle compete with that type of "truck activity" anytime in the near future.  Also nobody that uses a truck for truck type activities is going to be ok with "shit range" and having to sit around drinking lattes with their pinky sticking out at the "supercharging station" waiting for the thing to get a charge again.  The two things just don't jive together, so this "tesla truck" is for hipsters that think they do work.

 

It's like how hype beast kiddos wear distressed motorcycle jeans but can't operate anything that uses a clutch and a manual transmission.  The tesla truck is the distressed motorcycle jeans of trucking.

Indeed, its a continuous, even power band on a motor versus an engine which is geared. I suspect that motors aren't geared because they're optimized to provide immediate power as needed and are essentially off when not needed. Besides that, they also recover energy by harnessing forward momentum as the car decelerates to recharge batteries. I suspect that rather than needing gears to optimize the performance of the engine, which in turn can also optimize fuel consumption, the electric motor does this inherently by throttling the amount of energy given to the motor based on input (gas pedal). I know a combustion engine does the same by slowly opening valves and allowing more fuel into it for combustion, but likewise, it depends on gearing to optimize the process, as well as the resulting torque you receive in return.

DHABZ: I have a question for you.
DHABZ: why wouldn't you put a gear box on an electric motor?  LIke, why wouldn't it extend the range of the engine by allowing it to operate at a lower rpm?
 
SpeedAddict: It can operate from zero rpm
SpeedAddict: That being said, it's not a bad idea, and people do it
SpeedAddict: The majority of swaps keep a manual and shift it, usually starting in 2nd gear
 
DHABZ: so does it actually extend the range though?
DHABZ: and if it does, do you thin kthe reason tesla hasn't done it yet is because they want to sell it to people later after they've initially become married to the brand?
DHABZ: like as in tesla knows it's better to have a gear box, but they're "keeping it on the shelf" until they need to introduce the next money sucking idea to people?
 
SpeedAddict: Oh, Tesla specifically
 
DHABZ: well not just tesla
DHABZ: i'm just naming them from a perspective of them being the major name everyone knows and buys.
 
SpeedAddict: Well, it depends on the motor.
SpeedAddict: Like, I am using brushed DC, they do have a powerband, and don't like to be spun particularly fast unless you do special things to the rotor to keep it from flying apart.
SpeedAddict: That's why a lot of the conversion guys like gearboxes.
SpeedAddict: They are also air cooled, you don't want to lug them necessarily because that means high amps and low airflow and high temps
SpeedAddict: Since the fans are spun at motor speed
SpeedAddict: Tesla has a liquid cooled, high power brushless
SpeedAddict: So a lot of that goes out the window.
SpeedAddict: Cooling isn't an issue, you've got no brushes to deal with

SpeedAddict: Anyway, if you have a motor with a perfectly flat powerband that can operate at all rpm without issue, there is no reason for a gearbox. It would add unnecessary weight, volume and complexity
SpeedAddict: You don't have nearly as many parasitic losses as you do in an engine
SpeedAddict: Having to power the valvetrain and all that extra stuff

Seems to confirm what I'd stated, though I didn't mention anything about how it added complexity. As far as I know, most EV's have a flat powerband. Just no reason to gear it since it doesn't affect the torque at any given speed or optimize / conserve the energy consumption.

Also, I would think that in an EV, the powerband is programmed anyways. Even those without a flat powerband, probably have it programmed in sort fo like a more integrated flight control you see in some automatic transmission sports cars.

I bet that thing is bad ass.  I'm much more interested in electric bikes (super moto/dirt bike specifically) than I am cars.

 

Fastest gas bike I've ridden was a ZX10.

 

Sounds like gearing isn't an issue for the Zero bike..... does it even have gears?  I haven't looked up the spec on it.

So I did a quick scan of the thread, how is it that the Hyper Car Porche 918 Spyder is more efficient than a Toyota Prius?

Now, I'm going to keep it short.  I don't think we are quite there yet with having a 100% electric car that can provide a long mile range.  This beast is dominating at 420mile range and it's super flexible. 

 

Combining gas, electricity, and wind, will always have the better outcome. Mshiet, add some diesel somewhere in there and guess what? Mars bitches, to there and back.

 

Pwned.

Sunday night I was chilling w a bud who has a Nissan Leaf

 

40 mile range

 

 

how the fuck does anyone in CA live with that? Everything is highway! 30 min here, 30 min there.

I can tell you how.  A motor becomes more efficient the closer to "race car" it gets.  The fastest cars in the world and the heaviest hauling diesels in the world are "efficient" when compared to the engines used in commuter vehicles.  I don't think the Porsche's ICE is using the Atkinson cycle either, which is the Prius's main selling point.... a "more efficient" engine cycle.  The point is, a Prius is the furthest thing from "race car" possible even with it's 20 ft/lb of torque on demand from the electric motor or whatever it is.

 

All it takes to "be more efficient" than any hybrid is a set of big cams, high compression, excellent cylinder head design, excellent temperature management, etc.  This is not the selling point of nearly any hybrid that is sold today.... their selling points are "be green" and "save money".... which is funny because efficiency does save money.  I think they're only more efficient than older cars from the 90s.  Newer direct injection engines with 2x spark plugs per cylinder have no problem using up the available fuel injected to completion.  Also, when you combine that with things like "variable displacement" (nissan motor) and "variable valve timing" and "variable length intake runners".... you end up with a very efficient ICE..... and that's exactly what F1 uses.

 

I'm not a huge fan of Audi, but check out some of the tech they use in their modern TDI race cars.  Makes the "high tech" of electric cars seem like banging two rocks together to make sparks vs having a tesla coil.

Don't forget that range is severely decreased when hills are involved.  Also, when there's "no traffic" it's been proven in ICEs that traveling above a certain mph starts decreasing mpg by an exponential number.  This means if your hipster electric/hybrid car isn't fuckin bad ass at getting through the wind then it gets shit range once the mph gets high enough.  So like, you probably can't do 40 miles at 85mph.... and that's not a huge turnoff for most people that would buy a car like that because they drive like snacky cakes.

 

I learned about this concept by going to the Texas Mile race and talking with the car owners there.  Here's an example, and I'll just use Ford GT's.  This is hypothetical in terms of the numbers used but the concept is true.

 

500hp Ford GT -> perfect launch -> perfect gear shifting -> @ 1 mile reaches -> 160mph

1000hp Ford GT -> perfect launch -> perfect gear shifting -> @ 1 mile reaches -> 172mph

 

Why is it that it took double the HP to do 12mph more than the other car?  The answer is because of drag coefficient.  Even though the two cars are shaped exactly the same, the wind acts upon them exponentially more as speed goes up.  This is why if your hybrid car or electric car is shaped like a brick (which teslas are not) then it's working directly against the idea of getting long range. 

 

This is also why you see all the "trailer skirts" and "aero mods" on 18 wheelers.  Those guys are literally trying to squeeze 1% fuel efficiency out of an entire fleet of trucks because it's worth millions to do so over the life of the truck.
