Petition to oppose FMCSA speed limiter mandate

Let's do some math shall we?
10 hours with an average speed of 60mph is 600 miles.
Increase your average speed to 65mph and that's an additional 50 miles.
An extra 50 miles a day, 5 days out of the week at a pay rate of .45cpm which any of us can make hauling vans for a mega carrier adds up to an additional $112.50 a week or $450 a month. Want a new car? Well, there's your new car payment. Increase your average speed by 10mph and there's your mortgage payment. Turning down trucks hurts drivers wallets.

It's not physics though. Fuel efficiency has more to do with RPM's than speed. Where that "sweet spot" is on the RPM's where peak efficiency is achieved is going to vary from truck to truck. In top gear the optimal RPM range for peak efficiency may be around 60mph or it could be closer to 70mph depending on how the truck is geared. Physics effects MPG's to the extent of aerodynamics and weight. As for the optimal speed that will be the speed at which optimal RPM's are achieved in top gear for highway driving. So no, slower is not more efficient which is why the city mpg rating is going to be lower than the highway mpg rating on any vehicle despite slower speeds during city driving. If the slower you are the more efficient you are were true then city mpg ratings would be higher than highway mpg ratings.

 

@rollin coal already beat me to what would have been my rebuttal

 

You could put me down for another grand

 

Correct, the starting and stopping adds another element outside of just speed. Perhaps I should have articulated it better but that was the point I was trying to make that speed alone isn't the sole factor in MPG's. Other things effect that. As for a lower gear that depends on the transmission. You might get away with that on the freeway with an 18 speed but optimal RPM on a 10 speed in 9th gear is going to be around 45mph. Do you want to drive 45mph on the freeway where the speed limit is 75? If so you must be hauling sand boxes out here in WTX and are the first I've met to speak English.
