Maybe you could look around and find an electric motor that can be installed on the car somewhere to give it a boost on hills.
Possibly a motor driving a belt onto the tailshaft or similar.
Then you could use the downhill runs to charge a battery and run the motor going uphill.
A small DC motor could be setup to be a generator when driven by the car and a motor when driving the car.
