For that price I'd think they would include a control system.

Still looks like a neat package.

I think that these are coming in at around 7k. Solid build. They're kinda fun. They run a wavetrac LSD standard 8.3:1 and 11,000 rpm limit (voltage dependent), have full integrated motor and controller cooling pump, just add you own radiator and axles. Then all you need is DC source/BMS/Charging and you can run it. Talks over CAN in case you want to get fancy with a dash/vcu setup.

$7k is very reasonable for that setup, is the transaxle sourced from an OEM vehicle or your own (BW?) design?

Most important question: where’s the rwd version?!

Mount it lengthways and make it AWD.

You could just mount it in the back and use a De Dion axle

That's it, I'm selling my Volvo and getting an Alfa!

Seems like the iM series is what a rwd vehicle would use.

So what's the cost on the different levels of iM packages?

like stick axle?

Its a BW design that has been modified to suit the aftermarket and OEM alike. 430nm of tq at the motor, and all in at like 260#s. That whole unit is small enough to fit in the back of just about anything. Take a Honda s2k rear subframe and cut out the diff, and swap in the tip of the gearbox.

The gearset is the same as the BW 31-03 gearbox. So there are several ratios available from like 5-10:1.

The iM series is basically as universal as it gets its an integrated motor and inverter/control module. Porsche bellhousing bolt pattern, and the BW e series gearbox mounting. There is an off the shelf Transverse gearbox option that looks like an autotragic, but its a single speed with low reductions (2-3:1) and then theres an offset billet box thats 2.6:1 and would mate to a t-case or direct to diff... We have done a few Ford 9" IRS prototypes and it looks like we might have something like that in the catalog by this time next year.

That'd be a good question for Sales. Its not much between the iM-0225 and the iM-0375, but going to the iM-0425 is a huge jump...

There is a longitudinal option. It’s a 2.68:1, so second gear ish that would pair well with a 3.73, that and 400+nm should get a brick moving. Speed limited-ish, but 11k, 2.68:1, 3.73;1, 26” tire… top speed wouldn’t be slow.

Looking over that gave me a really bad idea of dumping the 2JZ out of the rustang and putting two of these in there instead.

Its looking like our battery modules are suffering from the semiconductor shortage.. BMS fixings and such have affected timelines for full release.

But, I put together a BOM for a modified Tesla model 3 pack ~75KWH that comes in just under 12k with charging, cooling, heating, BMS and the connection bits.

Depending on how the next year moves, you might see a pretty ok decrease in price on all things EV.

12k including that battery pack?

What kind of range would that be on something like a 240?

[JohnMc]

$12K for a battery pack plus $9k for a motor/controller, if I'm reading that right.

Somewhere in around 200. Figuring the typical miles/kWh at 3mi/kWh with some reserve for capacity depletion over time. And throw a +/- 15-20mi in either direction based on terrain and aero.

And yeah, 12k would be pack only.

[Swedbrick]

It's a shame hydrogen fuel cells are not really commercial yet, the battery investment is a big hurdle for the average hobbyist. Although given the platina in those, they'd probably be similarly priced per kg as a catalytic converter

So looking at 21k or so for a battery pack + motor.


If you had to guess,,, whats the best and worse case scenario for price reductions next year?

Best case 10% reduction, worst case, another 15-30% increase in tariffs coming out to 10-15% increase in consumer costs.

But with the used market for batteries growing, the pack costs should be declining pretty rapidly.

There has not been much action on this thread for a while.

I myself would want a hybrid of sorts. I know it is unfeasible, but a RWD Volvo with electrically driven front wheels would be interesting.

[culberro]

This company does a hybrid assist system for pickups using components that I’ve linked to previously.

You can get the motor and controller for less than $2k. You’ll need a battery pack and some controll system computing to make it all work well. Or just have a “boost” button ;)

These systems are kinda cool. I've been playing with some super analog e-boost things, and I think there could be a way to implement most of these kind of controllers on a car with a 0-5v tps. Most of these controllers are TQ commanded by a 0-5v signal, and a drive,neutral,reverse switch. So take an RPM activated switch, torque command signal T'd into the TPS signal, and have the controller run off of those. E-boost at gas engine RPM/TPS. So say RPM switch active at 2krpm (really anything above idle) selecting e-motor direction, secondary gear switch selecting e-motor direction in fwd gears as a failsafe for only commanding in gears of movement, then tps signal commanding torque.

Then theres the option via stand alone EMS like megasquirt. Its got a nice accel enrichment feature. So when AE is active, the e-boost is active.

Or more complex is a CAN command interpreter that would deal with the CAN messages from your fancy COBB access port or stand alone, etc. And developing a tabled view of the gas engine status and implementing a torque command for your needs.
