[QUOTE=S31-Syntax;49329183][I]Holy shit.[/I] There is no way that electric cars [I]aren't[/I] the future. The drivetrain seems inherently superior.[/QUOTE] Yeah it's pretty amazing what they can do. I'm looking forward to seeing what Tesla's new Roadster in 2019 can do. The drive trains had some reliability issues when the Model S first came out but it looks like Tesla resolved the issues now, on their own dime. I would also really like to see a Tesla pickup truck or a semi, Musk has expressed interest in doing both. I guess he is waiting for battery technology to improve slightly more though. Battery industry is seeing a 5 to 8 percent improvement to energy density every year, so in 2020 we could see something with a battery pack equal in size and weight to the Model S's but with 115KW - 125KW capacity.
A 762 horsepower car is fast who would have guessed That car is cool but it's not fast only because it's electric but mostly because it's fucking poweful
[QUOTE=galimatias;49336599]A 762 horsepower car is fast who would have guessed That car is cool but it's not fast only because it's electric but mostly because it's fucking poweful[/QUOTE] Too bad it drops off like a brick over 60mph
The wheels on the car in the thumbnail are hot. Suit it perfectly. It's going to be interesting to see how the Model 3 performs when they release it next year-ish.
[QUOTE=galimatias;49336599]A 762 horsepower car is fast who would have guessed That car is cool but it's not fast only because it's electric but mostly because it's fucking poweful[/QUOTE] It's actually not even remotely close to that powerful. It's severely limited by the output of the packs. 85D is 417hp, P85D is 463hp, and there's apparently still some argument about how powerful the ludicrous upgrades are. It's not much more than 500 hp, and it's not sustainable power either. The car will very quickly overheat if you are trying to sustain anything close to that power output.
[QUOTE=S31-Syntax;49329183][I]Holy shit.[/I] There is no way that electric cars [I]aren't[/I] the future. The drivetrain seems inherently superior.[/QUOTE] The average person's electric car isn't going to be half the car a Tesla is. More like a Nissan Leaf or Ford Focus Electric. They are slow, their range is awful, and they are expensive - the Focus Electric costs $12 grand more than the standard model. The Tesla and the various German electric cars are the exception because they're >$60,000 luxury cars with >300hp. I don't see the situation changing that much in the next decade; there's no getting around the fact that electric motors and batteries more exotic materials than an ICE.
[QUOTE=S31-Syntax;49329183][I]Holy shit.[/I] There is no way that electric cars [I]aren't[/I] the future. The drivetrain seems inherently superior.[/QUOTE] Sure, all your torque is available a 0 RPM. Until you run out of battery 10 minutes later. They don't last very long when under continuous load of this magnitude.
[QUOTE=galimatias;49336599]A 762 horsepower car is fast who would have guessed That car is cool but it's not fast only because it's electric but mostly because it's fucking poweful[/QUOTE] It doesn't work that way. This is a bit of an oversimplification, but the general rule is horsepower gives you top speed, torque gives you acceleration. Again, not that simple in reality, but it's just a generalization. The reason it accelerates so fast is because of the torque, not the horsepower. Electric motors make so much more torque per horsepower than internal combustion does, and on top of that, they make that much more torque the entire time, not just at a high RPM, that's why they accelerate so fast.
[QUOTE=Saber15;49339708] I don't see the situation changing that much in the next decade; there's no getting around the fact that electric motors and batteries more exotic materials than an ICE.[/QUOTE] Not with that attitude. They're only expensive because they're not in such a mass production as regular cars. That's the whole point behind Tesla. To ramp up to that point. As it stands the batteries are the bottleneck. But they can be 100% recycled. Once they're here, they're here. Whereas with ICE We gotta keep mining oil out of the ground to sustain our way of life. EV's will overtake ICE in time.

Because of back EMF torque goes down as motor RPM increases [t]http://i.imgur.com/F2YDb4K.png[/t] In fact because of this, any decently fast car will be faster than a Model S at speeds over 60mph

[QUOTE=l337k1ll4;49339782]What's important is the torque is there low down.[/QUOTE] Which is an entirely different statement than the power being there the entire time. Tesla's have surprisingly little kick at high speeds. Yes the throttle response is effectively instantaneous, but they simply do not 'pull' at high speeds because of the enormous falloff in motor power.
[QUOTE=Goz3rr;49339854]bio/e-diesel (if produced with green energy) is carbon neutral and has the added benefit of reusing pretty much our entire distribution infrastructure[/QUOTE] Biodiesel is a good alternative but still requires massive infrastructure changes. There's no way we could produce enough by traditional farming. Algae farming might hold up. I figure we'll always have a biodiesel ICE market, but electric will take most of the market.
[QUOTE=Goz3rr;49339854]bio/e-diesel (if produced with green energy) is carbon neutral and has the added benefit of reusing pretty much our entire distribution infrastructure[/QUOTE] The big issue with bio fuels are the huge agricultural issues involved with it, especially in countries where industrial farms tend to be extremely damaging for the environment (most commonly the cause for deforestation/slash & burn in low economy countries around the world). While okay that stuff is going to happen regardless because people need farms, imagine a "cash crop" getting popular that essentially requires equivalent farm space to be equal to the total amount of space already being used for food world wide to meet the demand. It could easily be an ecological disaster at that scale. That said, maybe someone finds a way to make this bio fuel crop have amazing yield without requiring a huge negative impact on the environment, massive space, etc. But it really isn't there, yet. I'm willing to bet by the time it does theoretically get there, electric will already be there anyways.
I'm probably going to save up for a ~$1k~ beater, but I'm pretty sure a Tesla is the first quality car I'd want to own.

Yes the throttle response is effectively instantaneous, but they simply do not 'pull' at high speeds because of the enormous falloff in motor power.[/QUOTE] Isn't this what you really need when driving on roads though? On the track it's a drawback but it still has ample passing power on the motorway. It's also a sedan with more storage space than pretty much any other sedan, seats 7 people and is one of the safest cars ever built. Wait and see what they do with the new Roadster to worry about track performance. Off the line you will wreck just about any other ICE car, if you need to accelerate to get away from something you are probably going to be doing it from a stop / low speed as seen in this video: [video=youtube;35C5R5SxIfU]https://www.youtube.com/watch?v=35C5R5SxIfU[/video] You can see an EVs instant throttle response and high torque really comes in here.

Good electric cars are indeed expensive right now, but that will all change in a couple of years with the Tesla Model 3. $35k for high range electric car with good acceleration. We don't have exact details yet but we know it will have at least 250 mile range, and that the acceleration is supposed to be pretty good (but I would imagine it would be slower than the S). The Nissan Leaf will also get a 250 mile range model around the same time, as well as probably a bunch of other EVs. It's better to work your way down with a new technology since luxury cars have higher profit margins, allowing you to develop the cheaper models. They also show what the technology is capable of right now.

[QUOTE] He talks about the power being limited already at 3:30 [/QUOTE] Power limits due to heat, not because the battery is running out of power. [QUOTE] You do know that they're making a loss on every Model S sold right [/QUOTE] That's not even remotely true. I see this thrown around a lot. Tesla isn't yet profitable, but the Model S does make money. There's a significant difference, this comes from some clickbait article awhile ago. The profit margin of the Model S is 25%, with them expecting to push that up to 30% soon.
What the fuck over 2.8 seconds? It's still not as fast as an F1 car at 1.7 seconds, get your shit together tesla!
