Seems like a flawed idea to this 2015 24 kW owner. It would be an expensive "dead weight" most of the time, especially around town for day-to-day driving..
I google'd "Enginer range extender kit" and found their web-site. They seem mostly oriented to converting Prius hybrids to be the equivalent of a Prius plug-in hybrid. I didn't find the Leaf product mentioned on their web-site (prototype?), but maybe I didn't look closely enough?
FWIW:
One of my concerns about the long range 200+ mile plug-ins involves the enormous amount of battery weight ... over 1000 pounds. I think the Tesla's have batteries that weigh 1200 or more pounds for the 85 kW models.
My impression is that my 2015 Leaf with 24 kW has a battery weight of 500 pounds, making it a relatively heavy car for how small it is.
