The i might just be Regen Champion among production EVs, on a Watts per pound basis, though I suspect the Fiat or Spark would come out on top, I just haven't been able to find numbers on those cars yet. Neat to see how much more proportionately powerful our car is than anything made by Tesla in area of frictionless braking...

Car Curb Wt Max Regen W/lb
i-MiEV 2380 46000 19.3
LEAF 3354 40000 11.9
Model S 4647 60000 12.9
Roadster 2723 40000 14.7
Focus EV 3691
Fit EV 3252
Fiat 500E 2980
Spark EV 2989
 
jray, love your metric! Our great regen and manual control over it was one of the main reasons I bought the i-MiEV instead of the Leaf two years ago. For our international friends, I took the liberty of expanding your table to metricate it, and slightly re-ordered it.

Uh, we may wish to check the Tesla Roadster's regen numbers, as it's famous for super-high regen and strong deceleration. Now we can just keep expanding your table, but may need to double-check our sources as I've often found errors in published data. BTW, where's you find the regen power figures?
 
You're using the weight of the lighter non-North American versions of the i-MiEV. These models might have different regen levels since many of them don't have D, E, and B modes. So it would probably be better to use the North American weight of 2579 lb (1170 kg) in your comparisons.
 
I used a multiplicity of online sources for the data. I think this calls for another Google Spreadsheet. Is there a way to make a sticky for the original table of range stats for each of our cars?
 
Updated to add North American i-MiEV and BMW i3.

The i3 has by far the best, and best modulated, regenerative braking we’ve driven. The 125-kilowatt (170-horsepower) motor delivers up to 50 kW of regeneration to recharge the 22-kilowatt-hour lithium-ion battery pack in the floorpan.

OMG, alohart, thank you so much for showing us how to format a table.
Never did know what "Code" meant and I just now played with it a bit and see what it can do! :geek:

Meanwhile, back On Topic, any one of us can simply contribute to this table and keep adding to it and reposting it (I'm sure jray3 won't mind...) so the latest posting will have the most up-to-date and hopefully most-accurate information.
