The significant price increases for all fuel and in particular diesel have sent fuel consumption costs soaring for bus companies during the last several months. They must take advantage of every possible opportunity to reduce fuel consumption to stay competitive despite the sharp increase in fuel costs. Fuel consumption can be reduced by 8 to 15 percent simply by employing a preventive driving style. For a touring coach covering 100,000 km per year this would mean saving 5000 litres in fuel. For a fleet of ten buses the savings would add up to around 50,000 to 60,000 euros per year. The eco training from the OMNIplus service portfolio of Daimler and experiences from various fleets prove that these savings are possible.
Economic driving techniques reduce the variable costs for fuel, repairs, maintenance and tyres. "Down with the rpm, up with the load" is the motto. Theoretically an engine running at a lower rpm in a higher gear needs less fuel than running at a higher rpm in a lower gear, although the accelerator must then be depressed further. The eco trainings also provide important tips for tyre pressure. When the air pressure in the tyres is reduced by 10 percent the fuel consumption increases by up to two percent, and if it is 20 percent lower then fuel consumption could rise by four percent. Around 30 percent of all vehicles on the road do not have enough air pressure in their tyres, which means that significant savings are possible in this area. In addition, 95 percent of flat tyres are due at least in part to incorrect air pressure.
