100 mph

You should see our blogs and articles in Ev World about doing 100 mph with aero. Phil Knox co-authored them with me. One is titled 100 mph at 32 mpg and the other is an article on how these higher speed aero principles could be applied to trucks and buses at 90 mph.

I would have no qualms about driving my truck with aero at 90 mph. I have already driven it at 85 mph in West Texas where the legal limit was 80 mph and I got 16.2 mpg. I think with further improvements the truck could get 16 mpgs at 90 mph. By the way the truck was extremely stable at 85 mph but I was just testing for mpg data and as soon as I got it I slowed down to 80 mph. Then I passed 2 cops with radar in short order.

The truck was so stable at this speed I let go of the wheel and counted to 14 seconds (1,001 1,002 etc) before I had to take hold of the wheel again. When conditions are good, when the highway is built for it, and the vehicle has the appropriate aero mods and is good condition I have no problem with higher speeds then 75 mph. I think aero can allow us to go faster, safer, and more fuel efficient then vehicles without good aero.
