The Mercedes 'aero trailer'.
Mercedes has come up with a trailer design which it says cuts wind resistance by 18% and fuel consumption by nearly 5%, according to a design study that goes by the working title ‘aero trailer’ and shows how it is possible to reduce yet further the already low consumption, and therefore also the CO2 emissions, of state-of-the-art trucks such as the new Actros. The study was presented for the first time at the “Trailer 2011” show which took place in November in Kortrijk, Belgium.
