EU rules affecting HDV configurations
On April 15, 2013, the European Commission proposed new amendments to heavy-duty vehicle regulations that would permit more aerodynamic vehicle designs with improved energy efficiency and emissions behavior to be introduced onto European roads.
The amendments include derogations on the maximum total length of HDVs, allowing for existing trucks to be retrofitted with rear aerodynamic flaps and new trucks to feature these additional aerodynamic elements as well as rounder, longer cabin designs. In addition to improved aerodynamics, the new, rounder cabs will also affect road safety by improving outward visibility and lowering the risk of injury to other road users during low-speed collision events.
The proposed amendments also include provisions to facilitate intermodal container transport and to incentivize the adoption of hybrid HDV powertrains.
