2013 FIAT 500e
That is Emazing!!! (pun intended) That's 8.33% better acceleration by losing only 1.34% of vehicle weight, & you can do it for just over $700 in parts!!!Ok, so I got the Konig Heliums mounted with the wobble bolts & hubcentric rings.
I did a pre and post 0-50mph run to test for differences between the two setups (OEM vs 10lb lighter setup)... I got 6.0 stock and 5.5 with the Konig Heliums. =)
It should also improve range, at least in the city, so maybe you can check & reset one of you trip guages, & after a while you can give us a "before & after" number for that too. If you set the units to MPGe instead of mi/kWh, you get more precise numbers. Did you max out the tire pressures for the above-spec load, & low rolling resistance?
