Mudflaps on a Prime.

Lots of owners like them; myself I'd give them a pass. They can actually promote corrosion, because grit/muck invariably get's trapped behind them.

 

The mud guards on my 2023 Prius Prime are fairly small, though they don’t seem particularly smaller than other similarly sized vehicles I’ve seen with mud guards.

In terms of function, I think they some good. Though I think the functionality is definitely limited by the size.

That said, I like the appearance of the mud guards on the Prius. But it’s an entirely subjective opinion.
