A movie can be somewhat ruined by the purist approach, or it can be ruined by just simple stupid mistakes for no reason in the movie. Top Gun is replete with factual silliness but it's still entertaining if taken as being a movie.

An electric motor has full use of all of its torque at any RPM. By putting the motor(s) directly inline with the wheels, I can save inefficiencies through transmissions and linkages.

Crucially, it also means that, by detecting slippage, I can fire an EV off the line as fast as the rubber will stay stuck to the road surface. Any wheel that starts to slip will be detected immediately and torque reduced until it's no longer slipping. I don't even need an accelerator. I just need to tell it to "go".

Hey droog, there's a lengthy EV thread on the B1G forum, if you're interested.

Not trying to be thread police at all, I think we all know that's not my thing, but that board gets more traffic than this one does and there's been lots of good discussion on EV and the general future of the automobile (autonomous, networked, etc.)

Policing the Porch is like herding cockroaches.

Wasn't gonna take it and run with it. I just enjoy the fact that internal combustion requires linkages and all sorts of non-drive-train related add ons to function - mostly dealing with eliminating unwanted effects of internal combustion. They were fascinating machines full of clever engineering, but really made wheels turn in an extremely complicated way.

Growing up I had a set of toys called "Capsela." They were bubble-shaped modules that you linked together to create things like cars, or cranes, or tractors, or even boats. A couple of them had small electric motors, and then others had the gears and drive shafts, and others had the axles and wheels, or a propeller, that linked into all of that.

Before I'd ever looked at a diagram of a car, I'd played with those, which gave me a solid, basic understanding of what a an engine and drivetrain would look like.

Still available on ebay, apparently.

An EV with AWD can really launch like a bullet. And torque to each wheel is computer controlled. No diff, no tranny (usually), weight kept way low, very simple.

I was talking up EV delivery vans on the other thread. That could be the first market heavily changed.

Right now, charge density for storing power is the limiting factor. For decades, we only needed what was practical to drive a laptop computer for 8 hours. Then, we needed miniaturization to make a cell phone last.

We left the field of battery optimization static for a long time. I expect rapid breakthroughs in charge per weight in the near future.

When it comes to automotive engineering excess, I like to look at Konigsegg. I am especially awed by the tiny friendly giant (TFG) powerplant in the Gemera. This is your basic 4 door hybrid family sedan with over 1700 combined hp and over 8,000 ft/lbs of torque that will run on almost any fuel including hydrogen. Doesn't really need gears as it will go from 0-250 mph in the one gear.
Just the thing to load the kids in and head to the Chic-Fil-A drive thru.

It sounds super-affordable!

My best friend growing up, his first car was a 64 1/2 Mustang his dad got him so he could learn to work on cars. Body was in great shape, several parts needed replacing, and the entire breaking system. Only got in on just a little bit of that, as by then we had moved to Georgia and I was only visiting BR for a few weeks that summer, but we had some interesting times in that car before it was technically road worthy. I don't know why he didn't keep it longer. While lacking some amenities of modern vehicles, it had a lot of cool factor and was in excellent shape when they got done with it. But he had a boring Chevy pickup by the time we graduated.

Yup. One of my best friends in high school, had a '66 Mustang coupe, in sort of a light blue color. His dad got it brand new as a graduation gift from dental school, he'd used it as a daily driver for a while but it was only a weekender by that point. So he had it fixed up so it ran well, and gave it to his son. He was the first of us to turn 16 with an early September birthday, so I rode pretty much exclusively with him, until I finally got my driver's license in December. Even then, if the choice was my 1981 Dodge Omni shitbox, or his '66 Mustang, we were definitely taking the 'Stang.

It looked almost identical to this:

"1981 Dodge Omni shitbox"

Lol. The year, make, and model are different, but it's that last part that my first car really identifies with.
