FUEL ECONOMY INCENTIVE
The purpose of Fuel Economy Incentive (FEI) is to allow the
fl

target while providing the driver an incentive to meet the target.

OPERATION
Using the Fuel Economy Incentive option, a
fl

engine. If this fuel economy is exceeded, the driver will be awarded a slight increase to the
vehicle speed limit.
In this example the following limits are set as listed in Table 5-46.

Table 5-46
Fuel Economy Limits
If the driver has an average fuel economy of 7.1 MPG then the new vehicle speed limit is 62 MPH.
Vehicle Speed Limit + (Average Fuel Economy — FEI Minimum Fuel Economy) x FEI
Conversion Factor = New Vehicle Speed Limit
60 MPH + (7.1-7.0 MPG) x (20 MPH/MPG) = 62 MPH
The maximum vehicle speed obtainable regardless of the fuel economy is 65 MPH.
