That's the beauty of electric motors. The full torque potential of the motor is available instantly at 0 RPM and it never tapers off. I totally flat torque curve. As long as the batter can deliver a full charge to the motor, the motor will produce it's max torque. Many people don't realize this which is what makes those Tesla vs. XXXXX drag race videos all over YouTube so dumb. They will distroy just about any gas powered vehicle on the road simply because of the way the electric motors deliver their power to the wheels. There is a reason Chevy now has an electric motor for their "Copo" drag Cameros. I'm not a Tesla or electric car junkie but I do appreciate the technology behind the power trains and understand it's capabilities.
I see this current version of the truck being a great idea for short-haul or local trucking firms. The range isn't there yet for the serious long haul stuff, and I could see long grades over mountains and cold weather wreaking havoc on the range. I'm really surprised they went right for the semi-trailer market and didn't start with slightly smaller two and three axle good delivery trucks which would be better suited based on range.
