values registered by each individual manufacturer; different manufacturers may 
be combined for their average fuel economy value calculation, if being approved 
by the central competent authority.  
4.2.5 Vehicle entities pursued 4.2.4 may consent to end their combined calculation of 
average fuel economy value; their previous earned credits from exceed the 
required target value may continue to be used by the assigned manufacturer 
through agreement; the deficiency from under their target value shall be 
managed in accor dance with 4.2.8 of this Article.  
4.2.6 The same vehicle entity manufactured or imported different brands of vehicles, 
may calculate the fuel economy values separately for different brands, if being

4.2.7 Vehicl e entities with annual sales number over 100 units or values over 100 
million NT dollars being approved by the central competent authority may use 
their annual sales number for the calculation of average fuel economy value. If 
the calculated average fuel economy is over the target value, the earned credits 
may be accumulated for the calculation of next 3 year’s average fuel economy 
values.  After t his amended regulation become s effective upon its promulgation 
in 2018, if the calculated average fuel economy i s over the target value, the 
earned credits may be accumulated for the calculation of the next 4 year’s 
average fuel economy values.  
4.2.8 For vehicle entities mentioned in the previous paragraph 4.2.7, if their calculated 
fuel economy values are under their required target values at specific year, their 
subsequent market sold vehicles must comply with the average fuel economy 
limits being defined by 4.2.2 of this Article until the difference of calculated and 
target values are being complemented or acqu ired from other entities’ credits to 
regain their average fuel economy calculation by their annual sales numbers.  
4.2.9 For Electric vehicles or Fuel Cell vehicles (sedans and station wagons) that being 
sold by the vehicle entity, its sales may be multiplied by 10 as the correspond 
sales and being used in the calculation of average fuel economy  value; fo r 
Plug-In Hybrid Electric sedans and station wagons  with pure electric travel 
mileage over 50 kilometers, their correspond sales multiplier may be set as 5. 
The provisions 4.2.2 to 4.2.8 are also applicable and the fuel economy test 
values shall be rated by the competent authority in other provisions. 
4.2.10 Effective from Jan. 1, 2022, for the sedans  or station wagons  that being sold by 
the vehicle entity, i f its fuel economy value is higher than the correspond   5 average fuel economy target value as listed in provision 4.2.2.2, the multiplier s 
for the calculation of average fuel economy value are set as follows ： 
4.2.10.1 Over by 10%, set as 1.5;  
4.2.10.2 Over by 20%, set as 2;
