Quod suus via crustulum saxum

One wonders how well these older cars adapt to the unique stresses that result from the EV conversion -- specifically, to the additional load on the vehicle frame and suspension due to the EV battery. One assumes the converter must augment the load-bearing capacity of these system as part of the conversion (although maybe not so much augmentation is required for the frame on these old Detroit steel roadsters).

Lots of other things to take into consideration, too, like the change in the vehicle's center of gravity and the change in handling, for instance. It would be interesting to see the engineering that goes into this type of conversion.

Quod suus via crustulum saxum

This is definitely nice. Think there would be a decent boutique market for stuff like this.

Electric Pinto

There is a startup that is selling a controller, and 4 125hp ring motors that will fit inside the "envelope" of a wheel. $10k a set. Just need some custom software(they will work with you) and some cheap Prius battery packs, and 4WD 500 horses at the pavement.

Put that in a lightened Dodge Dart or a first gen Camaro/Firebird or an early Mustang. Stick a battery pack or 2 under the hood, and 2 in the back trunk/gas tank area. Keep the weight low and over the wheel areas.

If they fit, in the transmission tunnel as well!

Really? I've been saying for years now that wheel-mounted motors would be the way of the future of EVs, so much control available.

mrbigstuff,

The problem with that approach is you're messing with the sprung vs. unsprung weight ratio. To get a softer, more comfortable, more controllable ride, you need a greater sprung weight vs. unsprung. The objective is to reduce unsprung weight.

Which is why on "super race" cars, they even move the braking assemblies inboard alongside and next to the differential with only the axle shafts and hubs/spindles going out to the wheels. Your brake assembly
is no longer "outboard" with the wheels.

Or so I read somewhere ages ago. Anyone heard or read anything different?

sure, but I am talking about old-school styling with a modern drive components retrofit.

I don't think this is the one I read about a while back. But some info nevertheless.

I think I have said it before...but a conversion of my first generation Tacoma to EV with 4WD would be amazing, even if the range was only a 150 miles or so.

I think the setups I've read about are combinations of spindle, brake and bearing and electric motor all in one. So, I'd agree with you if we are talking about a car we know it today, but things will (maybe) radically shift in the coming years.

It really doesn't matter - putting more weight in the wheel assemblies leads to worse handling and ride.

You can mitigate that a fair bit by making changes to a number of components. You can drop 20+ pounds a corner with aluminum rims and brake drums, for example. And downsize brake size with regenerative braking. The brakes on my Prius are tiny relative to vehicle weight.

Right, the whole assembly is going to look much different on future cars. For example, there may be no need for rotors and calipers and axles. Think of howmuch weight that would save.
