We Got Our First Porsche Taycan Electric Supercar… And It Broke Us

We got our first Porsche Taycan Electric Supercar… and this one turned into our biggest EV challenge yet. What started as a simple inverter replacement quickly escalated into something much worse. Burnt components. Coolant where it shouldn’t be. Isolation faults. And just when we thought we fixed it… the Taycan refused to go READY. This is not just another repair. This is a full electric supercar teardown. ⚡ Rear motor removed ⚡ High voltage battery dropped ⚡ Inverter replaced ⚡ Cooling system rebuilt ⚡ Software programmed And still… it wouldn’t start. By the end of this episode, we realise something bigger is hiding inside the high voltage battery — and we have no choice but to tear it down again.
