Fuel economy, environmental impact and wear on the engine, brakes and tyres depend largely on the way you drive the vehicle. By adopting an economical driving style and anticipating the traffic situation ahead, you can reduce fuel consumption by 10-15%. The following section gives you some tips on lessening the impact on the environment and reducing your operating costs at the same time.
Anticipate well in advance
A car uses most fuel when accelerating. If you anticipate hazards and speed changes well in advance, you will need to brake less and thus accelerate less. Wherever possible, let the car slow down gradually with a gear engaged, for instance when you can see that the next traffic lights are red.
Change gear early to save fuel
An effective way of saving fuel is to change up quickly through the gears. Running the engine at high rpm in the lower gears uses an unnecessary amount of fuel. Press the accelerator slowly and avoid using the “kick-down” feature.
Avoid driving at high speed
Avoid travelling at top speed. Fuel consumption, exhaust emissions and noise levels all increase very rapidly at higher speeds. Driving at moderate speeds will help to save fuel.
Do not let the engine idle for longer than necessary
Engine idling periods are automatically reduced on vehicles with start/stop system*. On vehicles without start/stop system*, it is worthwhile switching off the engine at level crossings, for instance, or at traffic lights with a long red phase. The fuel saved after only 30 - 40 seconds is greater than the amount of fuel needed to restart the engine.
The engine takes a very long time to warm up when it is running at idling speed. Mechanical wear and pollutant emissions are also especially high during this initial warm-up phase. It is therefore best to drive off immediately after starting the engine. Avoid running the engine at high speed.
Regular servicing
Regular servicing can establish a basis for good fuel economy before you start driving. A well-serviced engine gives you the benefit of improved fuel efficiency as well as maximum reliability and an enhanced resale value.
A poorly maintained engine can consume up to ten percent more fuel than necessary.
Check the oil level when filling the tank. Oil consumption depends to a great extent on the engine load and engine speed. It is quite normal that the oil consumption of a new engine only reaches its lowest level after a certain mileage. This means that the oil consumption can only be properly assessed after about 5,000 km. Depending on your personal driving style, oil consumption can be up to 0.5 ltr./1,000 km.
Avoid short trips
The engine and emission control system need to reach their proper working temperature in order to minimise fuel consumption and emissions.
A cold engine uses disproportionately more fuel. The engine only reaches its working temperature after about four kilometres, when fuel consumption will return to a normal level.
Check tyre pressures
Always make sure the tyres are inflated to the correct tyre pressures to save fuel. If the tyre pressures are just 0.5 bar too low, this can increase the fuel consumption by as much as 5 %. Due to the greater rolling resistance, under-inflation also increases tyre wear and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all through the year; they will increase fuel consumption by up to 10 %.
Avoid carrying unnecessary loads
Every kilo of extra weight will increase the fuel consumption, so it is worth checking the luggage compartment occasionally to make sure that no unnecessary loads are being transported.
Save electrical energy
The engine drives the alternator to generate electricity. This means that fuel consumption rises when more power is required for electrical equipment. Switch off electrical equipment when it is not needed. Electrical equipment which uses a lot of electricity includes the blower (at a high setting), the rear window heating and the seat heating*.
