Cab manufacturers could slow aerodynamic improvements, trailer manufacturers warn

Wincanton has taken delivery of 115 new tractor units equipped with powered, height-adjustable roof fairings, reporting that height-matched fairings improve fuel consumption by about 5% compared with conventional fixed fairings.

The FTA has welcomed the approval by Transport MEPs of draft truck design rule changes, which will allow manufacturers to exceed current maximum length and weight dimensions. 

Waitrose is trialling six dual-fuel trucks with aerodynamic trailers in a bid to reduce carbon emissions and improve fuel consumption in its own-account fleet.
