Drive with gentle acceleration and braking
Why this can help
Anticipating traffic can reduce unnecessary acceleration and braking, lowering fuel use for the same journey. United States Department of Energy guidance supports a smoother driving style.
One possible next step
On a familiar trip, look ahead and allow space to respond gradually to traffic.
What changes the outcome
Traffic, vehicle and route determine the effect. Keep safe following distances and obey road rules. Do not add separate percentage savings for speed, weight and driving style on the same fuel use.
Your illustrative scenario
Over one year · with the assumptions below
You
25 litres of fuel used less
You + 10 friends
275 litres of fuel used less
1,000 participants
25,000 litres of fuel used less
These are scenarios, not measured personal or collective savings. One separate vehicle per participant. A shared car is counted once.
Your inputs
- Fuel per 100 km Before
- 7 L fuel
- Fuel per 100 km After
- 6.5 L fuel
- Comparable distance per year
- 5,000 km
Calculation of the difference: (7 − 6.5) × 5000 × 0.01 = 25 litres of fuel used
Calculation boundaries
Use the same vehicle, fuel, distance and comparable traffic, weather and load. A difference between unmatched trips cannot be attributed to this action. Do not add several driving improvements for the same fuel reduction. Traffic, vehicle and route determine the effect. Keep safe following distances and obey road rules. Do not add separate percentage savings for speed, weight and driving style on the same fuel use.
The initial values are editable arithmetic examples, not measurements or typical savings from the cited studies. Replace them with comparable readings for your situation. The sources support the mechanism and its conditions; they do not predict these numbers.
