RE:ISUZU NRR Sea says around 300miles but it's also the same for many other truck companies. Volvo with a heavier truck had just under 400 and Tesla 500. Most trucks are using a 2-3 speed trans.
Tesla is impressive and clearly ahead of the pack followed by Volvo.
My opinion but I think the coil switching is making very minimal difference and they are putting a premium price tag on it. The ranges seem to be similar except Volvo and Telsa.
Cummings (meritor) are building in house Volvo (parent of Mack) is building in house even bought a battery plant Diamler (Star and Kenworth) is also building in house, and Telsa
Everyone seems to have spent big to go the direction they are in except Hino and Mack. I can see Mack tying in with parent company Volvo.
These limited runs will depend on sales and the early years will see low volumes.
