The current supply chain issues have presented some challenges in getting parts we need. We ordered a custom, more powerful motor almost 6 months ago and it finally arrived. With the machining of a modified axle bracket, it’s now installed. The anticipation is that this motor will be able to fully power the vehicle while driving at speeds of 50+ mph. The previous motor wasn’t able to get all the way there – the gas engine had to provide some level of assist. This previous system topped out at about 30 mpg for combined city/highway driving. It remains to be seen just how much better this motor allows the system to get in terms of fuel efficiency.
