Have we figured out how to do a performance EV on a budget yet? Tesla, Faraday Future, etc. have proven that fast and electric can be had in the same vehicle, but as far as I can tell the tech is still too new to be had inexpensively. There are conversion "kits" out there which are silly expensive for how underpowered and low range they are, wrecked Teslas are still very pricey, maybe a used or crashed Leaf could lend parts to a much lighter car?

I know Nashco did that nutty Fiero hybrid, but I'm more interested in what can be done on purely electric power (although a light car with one of the large luxury or SUV hybrid powertrains could be fun)- anybody have secrets to share? To me, right now it looks like the only cheap-ish electric speed to be had is in motorcycles, and even then their combustion powered counterparts are FAR cheaper.

Used Nissan Leaf (they are ridiculously cheap) and Sawzall weight reduction?

I think someone on the forum was messing with a Spark EV. Might've even been Nashco.

I think the size and shape of battery packs/motors is a bit of a hurdle when trying to use them outside of their intended vehicle. Seems like you either have to deal with them being in a location that probably isn't convenient, or go the other extreme and make a custom tube frame to accomodate them.

I think a Leaf drivetrain in something like an Atom would be amazing, but I saw this video and

In reply to steronz:

That doesn't look like a whole lot more than what it takes to run a modern engine of ANY sort- at least the electric ones don't have a bajillion whirly bits on the inside

Right? All of the charging, drive, traction, hvac, accessories, and infotainment systems are integrated. Explains why the only OEM parts of most EV conversions are the batteries; everything else is aftermarket or custom made.

MT lists the Chevy Bolt is at 6.3 sec 0-60 and 1/4 mile 14.9 sec at 93 mph -- not Tesla territory, but neck and neck with a new Fiat 124 Spider Abarth and way quicker than my Soul EV or my Dad's Leaf.

I'm planning an EV project. Nothing is going to be cheap right now because of battery cost. Nashco's Challenge Fiero used a small amount of cheap batteries that he got a great deal on.

You'll end up spending 5 digits, or close to it, on any decent amount of newish batteries. The rest isn't bad - you can get motors and controllers from the aftermarket or the junkyard (or a combination of the two) at decent prices.

They're not THAT integrated but it is easier to set up the aftermarket systems. There's an aftermarket inverter/controller interface device called the UMC Drive that makes it easy to interface with OEM EV powertrains.

Stuff more motor and battery into an i-MiEV and you will have something.

and those make a leaf look like a Bentley compared to a Hyundai in the price comparisons used.

Used batteries from a newer hybrid or EV, a leaf motor and transmission, and a Paul and Sabrina AC motor controller will get you a fast EV.
