This is a fundamental flaw in the EREV design and it is the reason the Harvester is limited to 5,000 lbs towing and the EV can do 10,000 lbs. Without getting into an annoying discussion, it is energy in / energy out. Every EREV needs to be able to produce enough electricity in the gasoline engine to recharge the batteries at the rate at which they are being discharged during the largest expected sustained load. That makes for a difficult engineering dilemma. A big enough engine to pull 10,000 lbs 80 mph into a 20 mph headwind on I-10 for 200 miles (or up a 6% grade) is a totally cr@ppy design for everyday efficiency (cf the dumb RAM). So you derate.I will put my thoughts here: I have an old Chevy volt with a gas generator. It can barely pull itself up a hill if the battery is depleted and it’s depending on the generator to run the vehicle.
if the Scout doesn’t use some advanced logic to keep something in the batteries depending on either a selected navigation route or if the driver doesn’t use nav a screenshot of surrounding potential elevation changes, to keep the battery up, there will be some disappointed owners dragging ass uphill with the gas engine redlining.
BTW I had a 2011 Volt. Glad to see yours still going strong-ish.
