If you want better MPG, you just need to add EFI a wideband and $50 is aero streaming.

Truly that trailer offers a missed opportunity to make your MIEV into a streamliner

Also a VW is only a couple hundred bucks to convert to CNG if you want cleaner and cheaper.

and yes all that has been done before also.

Good Show, not the first VW pusher I've seen, there was one behind my 1981 comutacar back in prehistoric times also.

Now make it a 500cc diesel and :)

How about this notion for a zero emission range extender:

Interesting concept, though not zero emissions if run on liquid nitrogen. Wonder what the overall efficiency is, including compressing the gas, and the energy delivered on a tank.

My favorite range extender is the cheapest is drafting big semi trucks. A bit slow, but easy in the B gear position. I've seen huge gains in RR during drafting.

Great, I'd love some commuta-car pusher archival photos for the Historic EV Foundation if you have em.

Links on a cheap CNG conversion would be quite interesting... However, before I spend real money on another aircooled VW, I'd simply salvage a late model FWD vehicle as the pusher. If it ain't cheap, it ain't viable.

How a bout this for a range extender? Put it in the trunk with sprockets going to a drive shaft.

This would be good for performance too! But maybe want to avoid overspeeding the e-motor!

Another grant-funded endeavour (sigh). Nothing revolutionary, as the main effort is to bring the HV into the vehicle and hack/spoof the vehicle's existing BMS.

Occurred to me that this thread should be parsed into the following categories (and maybe its own subforum):

1) Onboard Electric Range Extender (e.g., Enginer)
2) Onboard ICE Range Extender (ugh!)
3) Electric Range Extender Trailer (the example above)
4) ICE Range Extender Trailer (AC Propulsion had a nice one)
5) Electric Pusher Trailer Range Extender
6) ICE Pusher Trailer Range Extender (jray3's toys)
