Hybrid AWD conversion

[Isaac Zachary]

I've seen where the original Beetle transmission was modified, a direct drive synchronizer from a completely different vehicle added to engage and disengage the front drive line, a differential, also from a random vehicle and Type 2 Bus rear hubs modified to become the front steering hubs on the modified 4WD Beetle.

seems you could use the trans axle from a AWD subaru. flip the R&P to get the direction you want

Welcome! We make a reverse-cut ring & pinion to suit Subaru transmissions and fully remanufactured reverse drive transmissions. These transmissions can be used with rear-mounted Subaru, VW / Porsche boxer engines for 5 forward gears. Add a Subaru engine and 2WD 5 speed transmission to a Beetle, Kombi or Vanagon without cutting the torsion bar.

Definitely a possibility for an air-cooled VW (or one that's been converted to a Subaru engine as well).

However, the OP was asking about a Toyota MR2 Spyder. And the idea seems to be to leave the ICE and transmission alone and add an electric FWD system. Correct?

Hard for me to interpret this without an MR2 on hand, but it looks like 57301A and 57308 would be the part to modify.

Yes, basicly 2 fully independent drivetrains.

I genuinly can't tell wich part is what from that pic.

That was my comment as well, and you're the one with the MR2!

It helps of you know the conventions for exploded diagrams. 53701 and 53702 are [likely] the Macpherson strut towers. There is a 'firewall' to the right, and radiator and front bumper group to the left.

What is there at the center of the front axle line?

Fitting all the electric components in an MR2 that still has the gas engine will be very difficult. The electric motor and inverter will need liquid cooling. Depending on the battery that may need liquid cooling as well. Onboard charger will be liquid cooled if you want to get close to the 11kW charge rate but even a 3.3kw charger needs cooling air flow. Probably want a junction box for the HV contactors. Also not sure how much controller support you’ll find for the Lexus MGR since it’s not common for EV conversions.

IIRC there was a conversion kit aimed at the adaptation of a Subaru transaxle into Vanagons, but it was only available for that dual-range 5-speed manual.
