Transport efficiencyExcellence in all areas
More freight per truck, more payload for busesLow dead weight = higher payload = less energy per tonne-kilometre / person-kilometreMore kilometres per litre dieselLow fuel costs and less CO2 output; less energy per tonne-kilometre / person-kilometreGreater safety in trafficElectronic assistance systems prevent accidents; new traffic information systems reduce traffic jamsMaximum reliabilityPassengers and freight arrive reliably and punctually at their destinations; service contracts ensure high vehicle availability and calculable costsGreater comfort for the driverSophisticated ergonomics = high concentration and alertnessMore service and flexibilityTransport efficiency ensured by expert advice at purchase, flexible rental facilities and fleet management
MAN offers an all-embracing efficiency programme for cutting the total cost of ownership (TCO) wherever it can be attacked.

MAN – RoadmapFuels and Drives
Internal combustion engines using- conv. diesel with bio – blends (HVO, FAME) and CNG- hybrid technology for city traffic
Conventional diesel (based on crude oil) with bio – blendsCNG
Internal combustion engines plus- increased XTL – blend of diesel fuel- hybrid technology for city traffic- plug-in hybrid for short distances
BTL for long distancesPlug-in hybrid for short distances & ICE as range-extender
Regenerative liquid hydrocarbons,hybrid as well on long distancesBattery vehicles for short and medium distances (together with further optimization of batteries and regenerative fed energy supply)
