Ducati is always advancing it's engine technology

there is SOOO much available out there to use

it is strange that there was never a discussion about this vehicle being an EV !

??

on the one hand it is touted as being a solution to the commuter vehicle, where a 20 mile range is all that is required !

yet on the other hand it is discussed how you can drive long distances on one tank of gas !

two totally separate different missions.

maybe hidden in the future plans will be an EV version ? Once battery density issues have been advanced ?

Surely their is an EV forum somewhere?
Very few EV circles discuss it much. Some consider the Elio a competition to EV's.
I think they should consider it a great donor vehicle for EV projects. It lends itself well to motorcycle EV drives which are developing fast.

EV groups tend to be very focused on EV for all normal uses, and in this they tend to think about current platforms.
I used to attend an EV club here in Phoenix and it was a little bit of a hard sell, since commonly they thought it was a niche vehicle.
I would add, this was much less open minded than I find on the street from any random person.
Even so, I did generate quite a bit of interest, even some related projects. Those did tend toward bike-trikes, so you can see it's a tuff sell in that group.

When the Elio is on the street in numbers, that trend will totally shift. The simple basis of cost to complete a project car will always appeal well.

ON the Elio itself, it's obvious that battery space will be needed, and that may restrict who is willing to engineer a solution. If you are creative I do see enough space for Li-Ion on a short range vehicle, and if very vigorous about it, more.

My commute is 22 miles one way and I can't charge up at work. I'd need 50 mile range and really about 100 to feel comfortable leaving the house and being able to make it to and from work plus any running around to meetings that I might face. But the Elio would make a great little platform for an EV... I wonder how long till someone puts a wheel hub motor on that back tire... wouldn't even need much in the way of computer control... just set the motor up to provide a little push when the car is going forward and have it regen any time the brakes are applied... sounds simple enough and it could be done with a small battery that only served to get the Elio moving from a stop... to begin with (and keep it simple and cheap)

Better yet, put front into neutral, use the back to accelerate up to cruising speed, put front into drive, the rear into charge, after charging, into neutral.
IMO using the motor to drag charge the back wheel, will use way less gas than it would pushing the car up to cruising speed. Just have it done automatically. Don't know how much mpg you would lose dragging around the weight of the battery and the motor.

I'd think that if the battery started out charged and it was used to give a good assist from say, 0 to 40, and when you apply the brakes, it would regenerate electricity like a Prius, you could have enough of a charge to get you up to speed for most if not all of a regular daily commute. Advanced electronics would allow it to go into regen mode more like a Prius but to keep it simple, ie cheap, I'm going with brake regen only. Besides, the Elio should really coast pretty far with it's aerodynamics and lower rolling resistance. There is another version of the "mild hybrid" where basically, the alternator is replaced with a motor generator that can be used to help power the car at the engine vs. at the wheel. It'd also be used like a regular alternator. There's yet another mild hybrid that uses a motor generator instead of a starter. By replacing already existing components, the cost is somewhat abated.

I'd really like to try the powered hub design though. They are predicting it'd cost about $3,000 to implement in a car but that's using two hubs where we'd only need one of course. The battery could also be smaller as the car is lighter and should be better on battery. maybe the Elio will have an Elio Sport-E that uses that 73hp hub motor to both make it into a hybrid as well as make it much more sporty. Maybe the 2016 model...

I'm not really one for making things more complicated unless there is real evidence to show it's worth it, but I'm kinda diggin' this Idea. Simple hub motor and battery on the back with only an interface to the computer for throtle and braking coordination. Designed to be plugged in for the bulk of the charging, and primarily there to assist in saving fuel in acceleration or maybe hills. (And give a better 0-60 time if you really romp on it). I wouldn't want to see 'em work on it NOW, but in a couple years I can see it working for the next 100 mpg phase. And it wouldn't be hard to retrofit into older models either. I like the idea as a plug-in hybrid light, cause you get into too many variables charging the battery on engine power, i.e. is it worth it? And a small battery isn't so much weight to factor in. If it goes dead while you are out running errands, then you loose a few mpg and the ability to lay rubber off the line when that Prius pulls up at the light, but the vehicle would then just be it's normal 'stock' self. Not the end of the world. As far as regen braking, I've never seen anything that indicates it is all that efficient, but why not throw it on, since all the components are in place anyway. I would think about maybe some potential solar charging of the boost-battery system while the vehicle is sitting in the parking lot at work or whatever. There are some interesting flexible panels and transparent ones too that might be interssting. Only engineering question I see is; do you want to carry two battery systems on board? One for the drive-boost and one to start the engine..... doesn't seem that efficient. But I do like your idea, especially since I was thinking of making it a hoby to mod an Elio up to 100 mpg.

You'd want two battery systems in case you ran down the hybrid battery. The Prius we have is like that (daughter's car). That hub system is being designed as a retrofit kit. It should be able to be put in as a plug and play system almost. I'm betting the aftermarket criminalizes more choices like the hub motor. I hope so. It would be neat if Eliooffered that Sport Hybrid model I'm dreaming of.
