How to save more fuel at car driving

Most fuel economize technics can be learned in 2 lessons:
Lesson 1: wheel bearings defect.
Lesson 2: the holes in the engine's exhaust.






The key to low fuel consumption: Understanding all the physics applicably for car driving. Most fuel economize technics can be learned in 2 lessons.

  Lesson 1: wheel bearings defect
Imagine Your car's front wheel bearings are defect. You hear a noise at low speed. The noise becomes louder and louder at higher speeds. When You reach 100 km/h, You think they will be irrevocably defect in the next seconds. You go behind a big transporter driving 90..100 km/h and enjoy the next tank stop. You can go in 15m distance into the wind shadow of a big truck. This is no safety problem, because big trucks have less deaccleration than small cars.

  Lesson 2: the holes in the engine's exhaust
Imagine You have some big holes in Your car's engine's exhaust. Your car is very loud when You drive in a common style. Imagine there is a city with a policeman every 50m. Every policeman will stop You for noisiness or for driving to slow. You have to be as fast as the other traffic, but be aware, You have also to be silent despite the holes. When You are able to drive with the holes between all the policeman without trouble, Your car will consume 25% less than DIN norm for city traffic. Clarification: the holes in the exhaust have nothing to do with the low fuel usage. They forced me only to change my driving style, because a normal driving style is terrible loud with this technical defect. I switched to the next gear at 1500 turns per minute. I tried to roll with as less changes of speed as possible. You can see the surprising results at my Renault Espace fuel statistic in winter 1995 to 1996.



  Simulate Your driving style in the staircase
A major factor in energy usage at city traffic is speed change. You can simulate this factor in the staircase of a 14 floor high building. Let's assume 250 cm high rooms and 30 cm thick floors. You see on the left to each floor a speed equivalent.

  • A green green traffic light 300 m ahead. It is unknown at what time the light will change to red. Your current speed is 53 (floor 4)
    • The real tilt turbo Porsche driver: accelerates to 99 (floor 14)
    • Standard driver: continues with same speed
    • Fuel economize driver: continues with same speed
    The light changes after 5 seconds to red.
    • The real tilt turbo Porsche driver: brakes to 0 (floor 0). He waits for the green light and accelerates again to 53 (floor 4) and wails all the time about the slow cars in front of him.
      Equivalent for all speed changes is 18 floors up.
    • The standard driver: continues with same speed. He comes to early and he has to break and accelerate again to 53 (floor 4)
      Equivalent for all speed changes is 4 floors up.
    • Fuel economic driver: let it roll. The car becomes slower and slower. He comes with 37 (floor 2) to the green light. He accelerates again to 53 (floor 4)
      Equivalent for all speed changes is 2 floors up.
