Alternative drive systems tested in light trucks
In the short term, the carbon efficiency of light trucks, which are used primarily for regional transports, can be optimized through aerodynamic modifications, the use of fuel-efficient automatic drive systems and by limiting their maximum speed to no more than 85 km/h (in the United Kingdom and Germany). As of the reporting year, these measures were made standard throughout Germany in particular. Alternative technologies such as hybrid or natural gas drive systems, which can be introduced over the medium term for even greater efficiency wins, are currently being developed and tested by Deutsche Post DHL in collaboration with both manufactures and suppliers. One of the highlights in 2012 was the introduction of the world's first "range extender" truck. The vehicle, with its completely electric drive system that is kept powered by an electricity-generating diesel engine, has helped cut fuel consumption by more than 20 %.
