Why all the Prius-bashing?! I love my Prius and think it looks awesome! A lot of auto manufacturers are switching to the general shape of the Prius, called a "Kammback" design. Then, unfortunately there isn't a lot to go on after that because to have efficiency you must have low wheel weight, and many of the same design features you see on the Prius, and other similar Kammback cars. We will just have to make that design sacrifice and reap the rewards of efficiency!
I wouldn't mind having an 18" option, as long as it didn't detract too much from overall range or performance. Wheels that are too big/heavy would probably adversely impact the EV range or performance.
If they were forged, lightweight 18s that didn't add substantially to the unsprung weight, then sure, why not?
