Why a boat-tail semi isn't as silly as it might sound
But a boat-tailed tractor trailer might be just what we need. Why? Because when fitted with such a piece of aerodynamic kit, total fuel-consumption reportedly drops by 7.5%. The tests in question were conducted by the Dutch PART (Platform for Aerodynamic Road Transport) public-private partnership platform on public roads. One truck without any aero-aid was driven around for a year, as was another truck with the boat-tail.
Not only did the boat-tailed machine get a 7.5.
