Depends on the vehicle and it’s size. The Jag E type conversion puts all batteries, controllers, motor and charging unit up front in place of the engine. No loss of cabin or luggage space. I’d suspect the 928 has a large enough bay to do similar. All depends on your range expectations and battery needed to give you this.

I reckon the 924 engine bay would provide enough space for the motor and a battery tray?
I know the battery unit is heavy but, combined with the weight of the motor, it surely wouldn’t be that much heavier than the engine, cooling system and everything else associated with the engine?

Or an added battery box in place of the redundant fuel tank.....spread the weight.

Yes, I suppose a full fuel tank has to be over 50kg?

I think the motor would bolt straight onto the diff. You're losing the bellhousing, clutch, torque tube and gearbox as well as the engine. So your whole engine bay is available for batteries as well as, as pointed out, the fuel tank space.

Most conversions retain a flywheel, clutch and gearbox.

Yes, still trying to get my head around that.
Most do seem to keep the gearbox, I’m assuming the gearing reduces the load on the motor?
I do like the idea of bolting the motor straight on to the diff, it would be another massive weight saving but, as mentioned above, I’m guessing it’s not practical due to load/gearing?

I think it depends on the type of motor. DC seems to need a gearbox but AC doesn't. Use AC direct onto the dif for an air cooled rear engined porsche!

Sometimes it's easier to use the reverse gear in the gearbox than control the motor electrically to make it reverse. And although they don't have a power band like ICEs, electric motors are more efficient at higher revs which is why Teslas - which don't have gearboxes - have something like a 9:1 reduction between motor and wheels while top gears in ICE cars are usually around 1:1.
