I wish they would go with a 4 cylinder ICE. Probably could even go down to 3. I want an ICE that can just barely keep up when I'm running on flat ground with a trailer. When going uphill I want to drain the battery a bit (and then recharge downhill). I want to be able to drive for 11 hour towing a trailer, stopping to recharged and fill the gas tank (both at once please!) every 300 miles.
The ICE is a generator rather than connected to the wheels. The truck operates as an EV at all times and then fires the motor when at low state of charge. How it runs is really not important as long as it charges the battery enough to extend range indefinitely. The game is about peak efficiency.
