Estimation of fuel-saving due to lightweight

• Long haulage truck = tractor and semitrailer

• Weight, empty: about 15 t

• Weight, fully-loaded: 40 t

• Driving distance 150 000 km/year

• Fuel consumption fully-loaded: about 40 l/100 km

• Fuel consumption empty: about 28 l/100 km

• Weigh difference: 25 000 kg • Difference in fuel consumption: 12 l/100 km

E-Mobility, light weight design for increased driving range

For battery electric vehicles (BEV), the weight of the batteries with the capacity to run a certain distance is 20 to 30 times the weight of diesel fuel needed to run the same distance.

In this case, light weight design has the potential to increase driving range significantly.
