55mph is a sweet spot where the engine is operating close to peak efficiency and air resistance hasn't yet exploded. There very much are cars that are most efficient at 65, but that is because they sacrifice efficiency elsewhere.
Peak efficiency is the intersection of many curves- gearing, rpm, aerodynamics, speed... Aerodynamics is possibly the biggest factor though, hence the common point of 55
- greatsuccess 13y ago55 MPH is nothing of the sort. My BMW reaches the same efficiency at 75 MPH as your honda does at 55 MPH. This has been debunked years, no centuries, NO EONS ago when Ronald Reagan decided to enforce a federal speed limit in exchange for provisioning interstate construction money. Its a fallacy, its wrong, and its well known. Stop spreading the 55 MPH is efficient pablum. Are you seriously all 18 year olds in here?
- trhway 13y ago>55mph is a sweet spot where the engine is operating close to peak efficiency and air resistance hasn't yet exploded. i think 55 is just the speed of EPA "highway" efficiency tests
- sliverstorm 13y agoAnother important bullet I forgot- the national maximum speed limit was 55mph until 1995. Cars were probably made to target that.
