In a trip in Norway with a Kona EV I managed to regenerate 5 kWh in around 15 km when descending from 1300 m a.s.l to 9 m a.s.l (the road from Turtagrø to Øvre Årdal). Kona allows a maximum 150 kW charge to battery when recuperating (measured with an OBD dongle), Taycan should allow up to 300 kW if I remember correctly. But as the Rally1 battery is probably quite small I believe their maximum regen power is lower, otherwise the C would be very high and the battery longevity would suffer.
Weighing 84kg, Compact Dynamics’ high-performance P3-topology hybrid system accommodates a motor-generator unit (MGU), control unit and battery in a compact housing, thereby delivering maximum power density. The battery for the hybrid system is supplied by Compact Dynamics’ partner, Kreisel Electric, based in Austria.

The unit consists of a 3.9kWh capacity battery pack which is coupled to the MGU, delivering 100kW (134hp) of power and 180Nm of torque during acceleration.
During braking and coasting, the system recuperates energy normally lost and stores it in the battery. If necessary, the battery can also be recharged by an external power supply (plug-in hybrid) during service breaks. To charge from 20 to 80 per cent will take around 20 minutes using the dedicated units.

The MGU, which operates at up to 12,000rpm, the battery, which operates at up to 750 volts, and the inverter control unit are sealed in a carbon fibre housing to resist possible forces and impacts in the event of an accident. The unit is designed to withstand a 70G impact.
