### The Automotive Power Crisis
As EVs demand 800V architectures and autonomous driving requires flawless power delivery, traditional silicon chips are hitting physical limits:
**48% efficiency loss** in silicon MOSFETs at high temperatures
**35km reduced range** per charge due to power conversion losses
**22-week lead times** disrupting automotive production lines
> *"Switching to SiC MOSFETs increased our drive inverter efficiency by 7%, effectively adding 50km to our EV's range while cutting cooling system costs by 30%."*
> – Chief Engineer, Leading European EV Manufacturer
