The Mitsubishi dealer where I bought Bear is slowly getting taken over by Toyota and Morgan. Wonder if they'll get the electric version in :mrgreen: .

Still have to wonder what % of max power can be regenerated by a rear-wheel-drive three-wheeler, without locking up the rear wheel as weight is transferred forward. Our i-miEV sports an amazing 125A/155A ≈ 80%. As more and more of us get exposed to high regen, going 'back' to a low-regen environment will be a non-starter. This was one of the main factors as to why I chose an i-MiEV over a Leaf five years ago.

Hello,JoeS, can you please explain further?

I was always under the impression that all electric vehicles with regen operated the same way.

What makes our little iMiev's so special as compared to the Leaf, Soul EV, etc?

Different vehicles are programmed different ways. Mitsubishi designed the i-MiEV with nearly as much regen force as motive power. I don't think any other production EV comes this close in terms of regen to power ratio. Also, since the i-MiEV is one of the lightest EVs on the market, this means that it has the most regen per pound of vehicle weight, making regen very effective. By comparison, max regen in the LEAF feels like no-pedal regen in ECO mode. Even when both vehicles regen the same amount of power, the i-MiEV will slow down faster since the LEAF is a heavier car.

I would not like going to another vehicle with weak regen. Unlike friction brakes, regen doesn't wear out and need replaced, and it doesn't fade on long, downhill descents as long as there's room in the battery.

Hi FrostyCanada - PV1 explained it well. Cars with very strong regen include the Tesla and BMW i3 (although it's my understanding that BMW backed off a bit from the very high regen that they first started with). Even though the Tesla max regen is only about 30% of max power, it has so much power available that even that amount of regen really slows it down despite the car's tremendous weight.

There is a worldwide UN performance standard in terms of deceleration above which the brake lights must turn on. The i-MiEV is still below that range.

On the i-MiEV, I tell people that when driving I have four levels of regen: zero (when placed into Neutral), and one for each of the drive settings. The 125A number is the max regen current in B I recall seeing on CaniOn (may have been 130A?), with 155A being the maximum measured current drawn when accelerating hard.

Back on topic, I fear that the single rear wheel drive of, for example, the SOLO, will preclude aggressive regeneration because of the concern over rear-wheel lockup on slippery surfaces. This point could be software controlled using the ABS sensors, but I don't know if they're taking the time to develop this yet.

They do a "lite" version of the EV3 - cheaper, slower, but probably much cheaper to ship from Malvern to where you are ;-)

This was one of the main factors as to why I chose an i-MiEV over a Leaf five years ago.

I just watched another of the Morgan promo videos about the EV3 (a Selfridges limited/special edition) and there's a couple of driving shots that show the rear wheel fairly clearly.
I'd guess it's easily wider than the combined width of the (very skinny) front tyres - as is the total rear contact patch of the i-MiEV compared to the total front contact patch - so maybe it could have pretty high regen like the i-MiEV does.
I'd love to test drive one to find out :-)
