My Big Fat Geek Wording - More ICE vs. EV debate
This is where the worlds headed. I am in my 20s but I find myself on the side with the older crowd. Im not too fond of electric cars. However I am aware of where we headed. I would just like some proof that they are actually eco friendly. The production of batteries isnt exactly the cleanest thing. And the recycling of batteries is even worse to my understanding. Does not inspire much confidence when you realize the only reason we are heading to all electric is for the environment but if they are doing similar damage whats the point?
Even Tesla who clearly runs the segment right now struggles to charge the batteries faster than 30 minutes. And even then You only acquire some 75% of range was it? thats all well and good but a long road trip is nearly impossible. Or so time consuming it would make more sense to just fly there or use a gasoline/diesel car. The i8 is quite the achievement for sure but look at the cost. Electric cars are extremely expensive compared to their gasoline counterparts. I am excited to see how we move into the world of electric cars but until these major issues get ironed out (which I am sure they will with time) I think combustion engines will be the choice of most people. |

From the auto manufacturers perspective, electric vehicles are a highly desirable business to be in. Why? Because a combustion engine is a disaster from an engineering perspective. It's inefficient (what, 30% efficiency at best?), it's complex as anything out there - especially when you factor in the transmission, differential(s), and other components necessary to distribute power to the drive wheels. Contrast that with an electric drivetrain. You don't need an engine, so there is no crankshaft, there are no pistons, valves, cams, belts, pumps, fuel lines, injectors - none of that. Furthermore you don't need a transmission, you don't need a driveshaft, and soon you won't even need a differential or indeed any gears at all. You'll just need four electric motors - one per wheel - and they are very efficient: over 90% so. Add some wiring to connect everything to the power source and you are done. Automakers have to continue to build ICE vehicles for as long as they are in demand. But they want that demand to subside sooner than later. Environment? Zero tailpipe? Well, that's great too, sure. But the real advantage is much less complexity both in the vehicle and the manufacturing and design of that vehicle. If you are an automaker, that's the primary motivator here - make no mistake about it. And what about those batteries and all the pollution that results from the manufacturing of them and from the collection of the raw materials needed to make them work? Temporary. Someday fuel cells, or maybe something even better, will make all that a thing of the past. By the time we figure out that battery production killed off a bunch of us (if it does, I mean - I'm not saying it as fact), it'll all be obsolete and forgotten. |

I don't care what people think about electric power but our grid is 1000% not capable of handling the number of cars on the road. I mean USA and everywhere else for that matter.
There are over 250 million vehicles registered in the USA alone. Imagine 90% of them attempting to suck down 50 to 100 amps at night for several hours. We can't even handle 100 degree days when everyone has AC running and cities have rolling blackouts. FYI AC units don't pull even close to 50 or 100 amps generally. If you do the math on any major highway and exchange all the gas cars for electric there will never be enough chargers to accommodate a fraction of the need. Simple math. Even a supercharger taking 20 to 30 minutes is equal to 5 to 7 combustion vehicles fueling up at a pump. Also, ICE fill ups people leave as soon as tank is full. For most electric charging stations people tend to plug in and go shop and cars might stick at the charger for another 15 minutes to an hour further exacerbating things. It just doesn't work at scale. Even now Tesla owners complain about supercharger congestion. All that said, BMW does need to get in the game and faster than they are indicating here. There are many huge problems to overcome. Musk knows a panel on your roof and powerwall battery are the only solution to scale this as the logistics otherwise do not work. |

Yes you are right. They are simplistic in design and have a lot of potential to be great. But I dont think they are there yet. |

Its insulting when these tech and car companies say range anxiety will be eliminated if they create 300-400+ mile electric cars. Range of the car is only half the equation, charging time and charging availability are the other factors, and I highly doubt those will be solved by even 2025. BMW is all talk but its very clear that they are treading lightly and would be perfectly happy if this electric car thing was just a passing fad. Tesla will reap either the benefits or the perils- at this point your guess is as good as mine.

Why put up with this when I can refuel a 5 Series in 5 min and achieve 400 miles of range? :

$4-5k less a year in gas. Not to mention it has zero emissions. Those are just reasons, may not be your reasons (nothing wrong with your logic/reasoning) but those are reasons.
