To add to this - the old Volkswagen 4 cylinder engines put out around 55HP. Your normal modern car is 200HP and up. That engine was in the Beetle as well as the microbus. Neither vehicle was a barn burner, but could eventually get up to 60MPH. But after you got to that speed it would be fine. I used to also drive a 1980 Ford Mustang with a 6 cylinder engine that put out around 90HP. The post-muscle-car era had some pretty anemic engines, but we got around.
