Fuel Savings Advisor 25 percent less consumption

25 percent less consumption

The carmaker endeavor to construct their vehicles always more fuel-efficient. This benefits but little if the driver can not simply keeps some rules.

Downsizing, lightweight, higher pressures - there are different approaches to make cars more fuel-efficient. One of the biggest factors affecting the consumption of the vehicle, but sits known to be behind the wheel. By anticipatory driving, the driver can save fuel, in fact without the highway Schleicher.

Up to 25 percent can be saved in fuel demand, according to automotive expert Hans-Ulrich Sander by TÜV Rheinland. For example, he calls the timely upshift than one point. "Modern cars can be in city traffic without stutter in fifth or sixth gear to move ," said Sander. Here, the expert contradicts a widespread belief " Driving in the lower speed range damage the engine in any way. "

For cars with automatic applies: When accelerating slightly Lupfen the accelerator, then selects the transmission of even the next higher and therefore fuel-saving gear. When approaching a red light, you should use the fuel cut-off and let the vehicle as long as possible without gas rolling in the aisle. The injection units interrupt the fuel supply when the foot off the accelerator. This also applies to downgrades.

Many modern cars use the start-stop system to save fuel in the state. For vehicles without this feature it is worth it in traffic jams or at red lights that take longer than 15 seconds, stop the engine. " One hour of idling costs at least a liter of fuel ," said Sander. Eco - driving programs of modern automotive regulate energy guzzlers such as the air conditioning automatically shut for vehicles without this feature, the driver itself should be careful, sitting or only as long as absolutely necessary to develop climate control Rear window defroster, they still drive the fuel consumption by a maximum of up to four liters per 100 kilometers in the air.

Also unnecessary ballast increases the thirst of the vehicle: At 100 kilograms, it is about 0.3 gallons of extra. Increase bicycle carriers and roof boxes not only the weight but also provide with additional wind resistance for increased consumption - ie dismount. Often overlooked is also that the tires should always have the correct air pressure not only for safety reasons: 0.2 bar to little increase rolling resistance, in the wake of consumption increases equal to ten percent.
