Aerodynamic detachable body components | If the stated condition applies, the number of points behind it should be entered in the negative or positive field depending on the prefix. | |||
Fuel consumption: | Points | Negative | Positive | |
Sun vizor | +2 | |||
End edge flaps | - 4 | |||
Towing vehicle side panel | - 1 | |||
Trailer/semitrailer side panel | - 3 | |||
Roof spoiler | - 6 | |||
Too large a distance between semitrailer and cab | +1 | |||
Tires | ||||
Tire inflation pressure too low | +3 | |||
Low cross-section tires 60/70/80% | - 2 | |||

Total: | Add negative and positive points | |||
Difference: | Subtract all the negative points from the positive. If the result is negative, then the vehicle is equipped to the best possible extent. | |||
Factor for determining the possible fuel saving | X 0.66 | Determine the possible savings potential in per cent, by multiplying with the factor 0.66. | ||
Result: | The calculated value provides information about the possibility of fuel saving in per cent, respectively the causes of high fuel consumption | |||
Further influences | The factors listed below influence the fuel consumption considerably. However, as they are caused by use or the environment, they can only serve to evaluate the complete vehicle with respect to the complaint of high fuel consumption. | |||
Load train gross vehicle weight/load increased | +6 | |||
Winter operation/driving in rain | +9 | |||
Semi-trailer instead of drawbar combination | -7 | |||
Type of road (medium to heavy expressway use) | +9 |
