70,000 test kilometres prove it: the MAN TGX EfficientLine saves up to three litres of fuel

70,000 test kilometres prove it: the MAN TGX EfficientLine saves up to three litres of fuel

  • "Consistently Efficient" Tour 2011 crosses finishing line
  • Tour result: the two TGX EfficientLine trucks save 3.3 and 3.0 litres of diesel fuel per hundred kilometres

On a comprehensive informational tour, MAN Truck & Bus demonstrated that with a truck consistently designed for efficiency, even today up to three litres of fuel per hundred kilometres and thus CO2 can be saved in long-haul operation. This is the equivalent of approximately ten percent less energy per transported tonne. MAN achieves this by rigorously designing this vehicle to save fuel - all with tried and trusted series-production technology.

After twenty stops in ten countries, the "Consistently Efficient" Tour 2011 has reached the finishing line in Munich. At each stop, efficiency experts provided information on how vehicle operators can effectively reduce the cost of operating their fleets of commercial vehicles while at the same time making a contribution to environmental protection. 1,200 customers and journalists visited one of the tour stops.

Dr Frank Hiller, Director of Marketing, Sales & Services for MAN Truck & Bus, is pleased with the customer feedback: "The interest shown by the long-haul transport sector in concrete ways of saving fuel is enormous. More and more companies are taking the logical step and putting their trust in vehicles that have been designed to be especially efficient, such as the TGX EfficientLine."

By comparison with the reference vehicle, MAN TGX EfficientLine 1 and 2 saved 3.3 and 3.0 litres per hundred kilometres respectively on the "Consistently Efficient" Tour in May and June 2011. The two TGX EfficientLine trucks consumed on average 29.6 and 29.9 litres per hundred kilometres. The reference vehicle, a TGX without efficiency package and limited to 89 km/h, did with 32.9 litres per hundred kilometres. The difference in average speed was little: about 2.3 km/h between the TGX EfficientLines and the reference vehicle. Every truck on the Tour did more than 11,500 kilometres. Tour partner Aral has ensured that the kilometres driven are CO2 neutral.

In addition, an independent measurement run in April 2011 overseen by TÜV Süd (the Technical Control Board), resulted in 2.9 and 2.8 litres saving, underlining the potential of the TGX EfficientLine. The results of the measurements are thus based on a solid 70,000 kilometres driven under everyday conditions on Europe's highways.

Results of stages in Tour blog

The MAN TeleMatics® fleet management system was responsible for collecting the measurement results on the "Consistently Efficient" Tour 2011. This tool provides the fleet operator with a central overview of vehicle consumption, engine data, position, driving times – in all, more than a hundred parameters. Clearly laid-out information on the individual stages can also be found in the Tour blog at the following address:

The MAN TGX EfficientLine

The MAN TGX EfficientLine is a semi-trailer tractor for long-haul transport, uncompromisingly designed for maximum efficiency. One of the important building blocks in this regard is the optimisation of drag: top speed is restricted to 85 km/h. Aerodynamic side cladding is obligatory as opposed to compressed-air horns and sun visors mounted on the cab, which are taboo. Air Pressure Management, daytime running lights, tyres with low rolling resistance and a new Intarder generation save energy. And because the driver has a great deal of influence on the truck's fuel consumption, an Economy training course at MAN ProfiDrive® is included in the standard scope of delivery of the MAN TGX EfficientLine.

The MAN TGX EfficientLine is a semitrailer tractor designed with the rigorous reduction of the total costs of ownership in mind. It is designed for optimum aerodynamics, no compromises: side cladding is obligatory, top speed is restricted to 85 km/h. Air Pressure Management, daytime running lights and a new Intarder generation save energy.
