What is the most economic way to drive on the highway?

What is the ideal speed of driving to save money? What's the most economic speed for your car?

Many drivers have their philosophy on this, but there are rules that have already been proven.

For most vehicles, generally the best fuel economy strategy is:

Hurry Up

Switch to “Shortcut”

Go up to 90 km/h

Maintain engine speed between 1500 and 2500 pm

In this way fuel consumption is the lowest, and the engine is less busy.

As for driving on the highway, the German organisation TהV recommends:

A speed of 70 to 80 percent of the car's maximum speed

Don't go 130 km/h

This rule applies especially to the weaker cars, which have no higher speed.

For example: A car at a maximum speed of 150 km/h must be moved between 105km and 120km perh in order to preserve opitmal fuel consumption. /Telegraph/ Periscopi/
