They did note all range testing with all season tires.
I wanna see a range test with 11,000 pounds on it. Well maybe not let’s be honest nobody is gonna tow long range with it. More of a product to compete with other toy cars like land rovers etc...
For the most part I’m impressed to see a truck with a low drag coefficient and decently low frontal area.
Considering it has 4 electric motors it’ll be great off road as well at the ohv parks.

1) Rivian's rolling resistance road load is about 18.2981-hp @ 100 km/h.
2) At an EPA test weight on the dynamometer of 7,443-pounds, it yields a Coefficient of rolling resistance near Cfrr= 0.014869609 on the mud and snow tires.
3) You could play with different test weights and calculate different rolling loads at the same velocity.
4) Bear in mind that with EVs, 'weight' can be an advantage, with respect to momentum-to-electric regeneration. Volvo published an SUV EV study indicating a curb-weight 'sweet-spot'.
5) On You-Tube, I provided AeroStealth some road load tables, which demonstrate where power is being absorbed out on the open road. You may discover that 'weight' is rather meaningless at 'speed.'
Look for John Gilkison You-Tube
