[Autocatalysts](https://www.materialinsights.org/chemicals/autocatalysts/) (chemical) and [Electric and hybrid vehicles](https://www.materialinsights.org/energy/e_evs/) (energy): 1 relationship.

## How they are linked

### 1. Price link: demand threat

*Cost and price · Moderate · Both ways*

Battery EVs need no exhaust catalyst, so their rising share erodes long-term platinum group metal demand, while hybrids still use catalysts. The EV proxy is the same car price index as for combustion vehicles, so its statistics cannot separate the two.
