Changing the transmission, transaxle and gearing might still be needed if a person wants to run faster.
Otherwise that new motor will need to spin well over 10,000 rpm.

Echo the sentiment that more snap, right off the line, may be possible (note the use of the word SNAP). Me, I am going to leave that motor drive train battery software universe alone.

But I will just be very happy now that Nader has sussed out a suspension fix, and tracked his LEAF (outlasted the overheating Tesla Roadsters), paving the way for others to safely follow. If there was a way to dial back the power assist as the car rose above a few miles per hour, I'd be game for that.

Nader, if you could just perfect the best wheel and tire combo... :-)

In order for aftermarket vendors (i.e.: vendors associated to SEMA) to start making affordable performance parts for a model of vehicle, it will need a relatively large fleet number and a following of enthusiasts interested in performance, aesthetics, etc. It will be a while before there will be enough Leafs for a company to start making parts like final drive gear sets and/or engine modifications. Also the basic stuff that always come out during the first few years of a performance model car like CAIs, cat-back systems, and other affordable power mods for ICEs won't be applicable here.

Tuning for the Leaf will definitely be a grassroots type of business. And it will only develop/grow if there is a fair segment of the fleet's owners that is interested in performance tuning. Nismo will most likely be the first to develop something along those lines. Tien already has a coilover kit (Nader's Leaf) and I recall reading a post that RSR will also develop a set of lowering springs.

Hopefully there will be some good interest in performance tuning for the Leaf and we'll see some strong aftermarket support in response.

Here you go, a 1997 GM EV1 Truck motor, its AC induction, and 85KW, 240V, 350Amps, 3 phase variable speed... only $3500, one of a kind on eBay:

Great if you want to overpay for a dated motor with only 85kw peak. What's the point of that? You can buy a brand new useless newer version of that motor on ebay for about $1200 from a guy that has been trying to sell 10 or so for years and years. I don't know why anyone would pay over a few hundred for this unless they want an exact replacement for an old truck.

One interesting point to consider is the Leaf Nismo, the racing version of the Leaf. By reports it is said to have the same drivetrain and battery system reconfigured for racing. The main difference is the car weighs almost 1000 lbs. less so it is a lot more responsive. Interestingly, though, the top speed is still around 90 MPH. You'd think that if they could make it faster with just some programming or other minor adjustments they would have.

So I say just buy a Tesla if you want to feel like you are going to warp when you hit the accelerator.

Mwah ha ha! Neither was a civic or a focus or neon but I've seen street and strip versions of both that are pretty impressive.

After a suspension upgrade the lack of power and inferior tires became immediately noticeable. Tires and brakes are pretty easy. Motor/controller/battery etc are a whole new world for me.

Ah, right, remember folks, nader has taken his LEAF out to Laguna Seca raceway. He has track times to improve! :D

It's not a performance EV and trying to make it one is silly. If you dropped an ACP 130 pound drive system in a LEAF it would smoke the LEAF race car. I can't believe they are calling it a "race" car because the performance numbers are on par with some home conversions. It's a low weight LEAF with a very low performance drive system. What were they thinking?

Nope, the Fisker Karma will smoke the Tesla, Dual 150KW Rear wheel motors, in performance mode is combines its 23KW Lithium pack (50 miles in pure EV mode) with the motor generator. 0-60 in 6.3 seconds in hybrid mode.

Of course we are talking about $95K entry level, or $109K for what you'll really want, expensive,but worth it, if you can afford it.

I say do what you love. There is no shortage of kids willing to put tens of thousands into their Civics. This always freaks out the engineer bean counting sorts. Custom mods and fab work are usually not about cost, practicality or ROI. It's about inspiration, exploration and individuality. I think it's great the LEAF is creating this sort of enthusiasm. The grey haired pocket protector crowd should simply step aside and let the FUN happen.
