Does anyone know if lowering the power on cars would significantly reduce gas mileage? It seems to me that average cars today go as fast as sports cars of the past. I remember in the 90s a typical family sedan went 0-60 in maybe 10 seconds, and even slower in the 80s. Now it seems like some of these family sedans go 0-60 in 6 or 7 seconds. If the slower cars of the 80s and 90s went fast enough for us then, they should be fast enough for us now.
