Searching for a “real” honda quad differential for E-Vehicle

Hi guys,
i signed up in hope to get an advice from you.

At my university, we are working on a small electric vehicle. For this reason, im searching for a small, lightweight differential which we can use in the car.

Sadly, most of the "differentials" used for example in the rancher arent differentials in the right definition.

Often there is used a solid axle, and as a reason of that, the differential cannot compensate the different wheel velocitys in curves.

The typical final gear does not do more than change the transmission from one final shaft to two drivetrain shafts.

coming to my final question:
Do you know any honda differential, which works as a real differential, allowing the wheels to have different velocities?

Thank you for your help.
