# Commission Regulation (EU) No 65/2012 of 24 January 2012 implementing Regulation (EC) No 661/2009 of the European Parliament and of the Council as regards gear shift indicators and amending Directive 2007/46/EC of the European Parliament and of the Council (Text with EEA relevance), Division 4.5: Determination of the model fuel consumption

Extent: E+W+S+N.I.

FCGSI shall denote the fuel consumption of the vehicle when the driver follows the advice of the GSI:
FCGSI i = FCn i, where Vn – 1 GSI ≤ vi < Vn GSI (for n = 1, …, #g) and FCGSI i = 0 if vi ≥ V#g GSI
FC GSI = Σ 28 i=1 P i × FC GSI i /100
FCstd shall denote the fuel consumption of the vehicle when standard gear shift points are used:
FCstd i = FCn i, where Vn – 1 std ≤ vi < Vn std (for n = 1, …, #g) and FCstd i = 0 if vi ≥ V#g GSI
FC std = Σ 28 i=1 P i × FC std i /100
The relative saving of fuel consumption by following the advice of the GSI of the model is calculated as:
FCrel. Save = (1 – FCGSI/FCstd) × 100 %
