2013 FIAT 500e
That's about 12% more range! (from 3.8 to 4.3mi/kWh) Also better acceleration (0-60, 30-50, 50-80, quarter mile, etc.) since all or half of each of those is above 30mph where aerodynamics get increasingly important....just by being 2" lower... at 75mph I was averaging 4.3mile/kWh vs usual 3.8 at that speed... I’m trying to find out if light wheels that are non-aero outweigh the difference between an aero wheel that’s heavier. Decisions decisions... I want to buy the Avanti Storms 10.9lb wheel but been reading they might each up the range more then gain...
When I got Advanti Storms & 205s there was no measurable range difference. My route is slower though, with the highest speed limit at 50mph. That means my wheels' extra aero drag makes less difference than it would at 75, & my stop&go means their light weight gives a greater advantage.
If someone can tell us what they get at stock height at 60mph, we could compare to my stock-height 2013's power use with Advanti Storms in 205s, which now shows 11kW on the display at 60mph on a smooth, flat, dry, level, calm road.
The only other aero thread I've seen is the rear "diffuser", which is also supposed to give a substantial improvement, especially at higher speeds (where ANY aero improvement shows most).
