I still have a carbureted car. It took a little bit of coaxing from a friend to finally ditch the points ignition in favor of an electronic distributor. It was a Mallory dual point, and ran great all the way to 6k RPM. If electric cars become law, I'll be an outlaw.
Just imagine we wont need to change oil...

That article is 5 years old. Not old for the auto industry but mega old for the tech sector.
AC permanent magnet motors are typically used (interior permanent magnet specifically) for their torque and power efficiency. AC induction machines are pretty uncommon these days in passenger vehicles. Brushless DC motors are more for low-power applications, not traction drives.
Yes a heater will consume more power, a lot of work is being done on optimizing this component for EV's. Once things like the inverter and battery heat up, you can draw from the coolant just like any other system. The motor is usually cooler than you think. At least on the outside. It's the rotor on the inside that heats up more than anything.

Actually these are prime candidates for EV's and autonomous driving. Uber, Lyft, Waymo, Apple... they're all pumping money into EV development. These companies are betting on the next generation of drivers never actually owning a car.

We'll have to change the name of the forum:

The wife and I both drive less than 10 miles a day. An electric or at the very least a hybrid will be at the top of the list for replacement cars for her. If Toyota would make a hybrid Tacoma, I'll jump on board!

Hey guys,long time lurker,first post.
I just bought a brand new 2050 Electromobile Dyna 88. Which battery will give me less electric motor wear,Ray-O-Vac or Energizer?

The electric motor in the Chevy Volt is three phase AC (no brushes).
The transmission calls for an oil change every 100,000 miles. Those who have done the service say the fluid looks and smells new. Makes sense because it's the torque converter that wears out transmission fluid... the Volt (and Bolt) don't have or need one of those.
The (pure EV) Bolt transmission doesn't list a service interval, lubed for life I guess.

Yup, these autonomous cars will know when they need to charge and will drive to an automatic charging station when needed.
They will know when you request it if it has enough charge to make it to pick you up and drop you off, if not, another car will come.
It again goes back to the infrastructure, need a place to charge, and charge quickly (which I don't understand why they are not looking into hot swapping batteries).
I saw a story a few years ago about a place in Sweden or Denmark that was working on a hot swap system, basically drive in over the device, pulls out the discharged battery, installs charged battery, and you are good to go, less than 5 minutes.

Solved with hybrids or in built generators.

Hot swapping or charging...
Hot swapping...there's a set of contacts that need to be made...contacts that need to carry massive current, remain clean, remain functional through many many different platforms, and need the structural integrity to be securely located...again in any number of vehicles and platforms. Requires standardisation (same battery multiple vehicles), and a secure fit that will be ensured without packing like a regular pack (second time around, it will rattle like a diamondback).
They can't even agree on a plug/charge rate...let alone a standardised battery.
Still need to find bulk electricity to charge the "rack" of batteries...the charging station will have yet another connection process/risk.

I have decided when I will buy an electric car. When you can no longer buy an internal combustion engine. Someone needs to justify the economics of an electric car. Initial cost, cost of recharging, range limitations(good luck making a road trip), cost of replacing battery pack etc.

Depends. If you design a fast swap battery standard and a single owner fleet, that'll work. Single vehicle owner wont' like to fast swap their battery or rent battery or swap at half empty often. Apple and Waymo use gasoline (or hybrid) for their planned ride haul deployment and testings.

Maybe not in the US, but in nations where oils are imported and cars are taxed (to keep its own currency stable instead of exported for fuel and foreign vehicle import), EV can easily be cheaper if they are not taxed or not taxed as much. Look at Norway for EV and Mongolia for used hybrid.

I was very skeptical that Tesla was here for the long term. However, their last earnings report was very encouraging and while I'm still a little skeptical, they might be able to pull this off. If it is true that their costs are continuing to decline and there is room for improvement in their design, its possible that they could make a real dent in the auto business. They have to be putting a real hurt on BMW and other luxury manufacturers. Tesla's selling at a rate of 400,000 vehicles a year in a 17 million market. Deduct pick-ups and add another factory and they've got a pretty good chunk of the market.
100% American made with no unions, no dealership overhead and hassles. They may be the next iPhone segment buster. If they can pull this off, I'm not sure the other manufacturers can profitably compete. Ready for another round of auto bail outs?

I welcome it. The electric power train is obviously FAR superior to internal combustion. Size, simplicity, durability, maintenance, smoothness, quiet, instant (and far greater) torque.
Just being able dump a transmission is reason enough. Even the best auto/DCT is slow and dimwitted vs a single speed with massive torque.
Hopefully within 10 years, 300+ mile EVs with 10-20 minute charging are common-place for under $30k

I'm sure they'd be a delight on a winter trip from PA to La Ronge, too.

As the owner/lover of gasoline powered cars, owner of several '60 muscle cars, the internal combustion engine has polluted our air. Things have gotten much better; just look at Los Angeles.
But the future generations need air to breathe. Not to mention a limited supply of oil. Of course studies vary, but BP said 55 years...
Producing the electricity to power plug-ins can be costly, as well. No free ride. I am currently installing solar panels...
So kudos to Elon Musk for his vision. These cars in in their infancy. More to come.
Just my 2 cents.
My cars:
1965 Olds 4-4-2-; possibly the most original one left
1968 Corvette L36 Roadster, mostly original. Boy do I have a lot in this one.
1998 Accord LX, 80K miles. Inherited from my elderly father.
2001 Toyota Tundra, 190K miles, perfect. My neighbors love to borrow it.
2006 Acura TSX, 180K miles, perfect
2013 Lexus GS350 F Sport. I love this car.
2018 Lexus RX450h. Hardly used.

Awesome post JeffKeryk. Great fleet. Drive your hybrid more.

You should have said "When they pry my IC from my cold dead hands...", as in we need an NICA, similar to the NRA. ...
Electric cars have a good role: As 2nd-car commuter vehicles, the majority of us who commute less than 80 miles each way (as a current Chevy Bolt gives you 238 miles with a 240v 30amp service at home). Long trips, better get a diesel or hybrid or efficient gasoline car/CUV.

The reason the RX is hardly used is wifey's place of work has a lotta terrible parkers (door dings).
She tells me she believes the fuel costs are less than her TSX.
We plan to use it going forward. All good.

"Cheap" Chinese electrics about to hit Canadian roads.
I can see debates over which brand of electricity should be used to charge the EVs. For longevity and bragging rights of course.
