The Spanish traffic authority Dirección General de Tráfico DGT (DGT), has revealed the fuel-efficient speed of driving.
According to a DGT posting cited by Mundo Deportivo, Many people think that driving slowly saves fuel. However, the DGT has clarified that the key to reduced fuel consumption is maintaining a constant driving speed.
DGT’s Fuel Saving Speed
Others have quoted anything between 80 km/h and 100 km/h as the “magic number,” but the DGT has now specified that 90 km/h is the sweet spot – provided other driving conditions are optimal.
The DGT recommends the following to maximize fuel efficiency:
- Maintaining constant speed
- Avoiding unnecessary gear-changes
- Limiting the braking and acceleration
The fuel economy of a vehicle is about more than just the cost. What is the best way to learn about? Drive more than just How fast can you move?.
Many Spanish drivers are experimenting with fuel-saving methods as fuel prices continue to rise. DGT flagged a few popular beliefs which are either outdated, or just plain wrong.
- The highest gear is used at low revs
Contrary to popular opinion, this will not save you fuel and can actually cause your vehicle to stall. - Let the engine idle when you stop for a short time
Many believe that stopping the engine is more efficient than leaving it running. In reality, if stopped for more than 30–60 seconds, switching off the engine is more efficient. - Driving with high engine revs
The engine will wear out faster and consume more fuel. Use higher gears when the engine is not under stress. - Keep the fuel tank full to save on fuel
Many people believe that a full fuel tank will save them money over time. But the extra weight can actually lead to higher fuel consumption.
How to reduce fuel consumption in other ways
The DGT promotes smart driving in addition to driving at 90 km/hr and keeping a steady speed.
- When appropriate, use high gears without over-stressing the engine
- Avoid sudden acceleration
- Regularly check the tyres pressure
- Vehicle maintenance is important
Although removing large items from the trunk or using less air conditioner can make a slight difference, consistent driving habits and proper care of your car are what will really make a big difference.
