minus-squareares35@kbin.sociallinkfedilinkarrow-up4arrow-down3·10 months agothat may have been the case during the carter administration, but the efficiency curve of a modern car tops out a fair bit higher than 55.
minus-squarefuckwit_mcbumcrumble@lemmy.worldlinkfedilinkEnglisharrow-up7·10 months agoMost cars still do drastically drop off in efficiency past 55mph, wind resistance is still the same as it was in 1975. Modern cars are more efficient at 70mph than older ones, but they’re still less efficient than they were at 55.
