Comment Just for fun -- F150 gas savings (Score 1) 305
I asked Gemini to do the following:
"Get the number of F150s on the road. Estimate the change to drag coefficient a sloped hood would make -- Try one which is 6 inches shorter at the front than at the windshield, and estimate the savings of gas per mile that would cause. Multiply that out by the estimated number of trucks and estimated number of miles per year the trucks drive to get a gas savings for just F150s with the lower front on the hood."
According to its calculations, which it lays out in detail (doesn't make them RIGHT) the gas savings would be 306 MILLION gallons of gas a year.
Here's a more reasonable one, limiting ourselves to MODERN F150's:
"Get the number of model year 2024, 2025, and 2026 F150s sold in the US. Estimate the change to drag coefficient a sloped hood would make -- Try one which is 6 inches shorter at the front than at the windshield, and estimate the savings of gas per mile that would cause. Multiply that out by the estimated number of trucks and estimated number of miles per year the trucks drive to get a gas savings for just F150s with the lower front on the hood. "
Darn, changing this in 2024 would have only save 36 MILLION gallons of gas per year today.
If you generalize that across all pickup trucks sold in the past 3 years, we'd be saving (again, this is just Gemini, not real science) we'd be saving 216 million gallons a year.
If we included SUVs in that, the number would increase, but the pickup truck is (per vehicle) the better effect -- doing it for all SUVs (and there are a LOT more SUVs than pickup trucks) would only save a little more than doing the pickup trucks.
The US burns 136 billion gallons of gas a year, so it's a small percentage, but still a big number. Note that your truck would be able to go roughly 25 miles further on the highway with that 6 inch drop in front, with exactly the same gas tank size.
