Daimler's Mercedes-Benz Truck unit along with Germany-based trailer maker Krone have teamed up to put together a linehaul tractor-trailer they say delivers up to a 20% cut in fuel consumption compared to existing combinations. The rig, rolled out at the IAA Truck Show in Frankfurt, Germany, consists of the latest generation Mercedes-Benz Actros over-the-road cabover mated to Krone's new Profi Liner Efficiency, an aerodynamically enhanced curtain-side trailer fitted with low-rolling-resistance tires.
