There is the example of LPG conversions, where you can take pretty much any naturally aspirated gasoline engine and convert it to LPG for a modest price.

- fyfy18 7y agoLPG conversion requires a lot less changes though. The gearbox and braking remain exactly the same. You need to make very few changes to the motor. Then you just add a little more equipment (fuel tank, computer and control system) on top.
- lallysingh 7y agoThe brakes would be the same, and you're just removing-not replacing-the gearbox.
- LeonM 7y agoFor front-wheel-drive cars (which about 95% of small cars are), the differential is embedded in the gearbox. So you can't remove the gearbox, or you'll have to place a new stand-alone differential, which will add significant costs.
- dsfyu404ed 7y agoJust make a shaft to replace the shifty gear reducing bits of the transmission and then bolt your electric motor to the now gear-less transmission. It should be pretty easy to standardize a coupling and mounting bolt pattern for the motor and then just bolt on whatever transmissions shaft and bell-housing adapter you'd need for the particular model. I'm glossing over the details but you'd need about half a dozen precision machined features and like three or four parts that are specific to a particular ICE engine/transmission application. Dimensions are such that you could probably buy cheap axles for a common application and then have them machined down to make your part. Parts cost should wind up under $200ea unless you need something expensive to machine (like blind female splines).

- onlingyding 7y agoAn electric motor, you'll need something to run the power steering pump too.
