European countries has been working in the last ten years in the implementation of high
capacity vehicles in road networks. The EU allowed each member state to use
combinations of cargo carriers with a modular concept, the European Modular Systems
(EMS). This paper analyses the real behavior in road test of the Euro Modular vehicle of
70 tons of maximum load (called Duotrailer). A route in real conditions is used and
comparisons between different vehicle typologies (Trailer, Gigatrailer and Duotrailer) in
terms of fuel consumption and emissions are performed. Results in the route tested show
that, as expected, the highest consumption correspond to Duotrailers. However, savings
with regards to trailers are around 22 % (per ton) and 26 % (per ton and m3), and savings
with regards to Gigatrailers are around 9 % (per ton) and 23 % (per ton and m3)
considering that the charge factor is higher in Duotrailers. Although emissions are higher
in Duotrailers, the load capacity is higher.
