This standard replaces GB 27999-2014 Fuel consumption evaluation methods and targets for passenger cars. In addition to a number of editorial changes, the following main technical changes have been made with respect to GB 27999-2014:
—The scope has been broadened for the purpose of this standard is modified (see Clause 1; Clause 1 of Edition 2014);
—The evaluation system for fuel consumption limit of vehicle type has been changed from the step classification based on curb weight to linear classification based on curb weight (see 4.2; 4.2 of Edition 2014);
—The fuel consumption target of vehicle type has been tightened up (see 4.2; 4.2 of Edition 2014);
—The concession multiples for accounting the corporate average fuel consumption of new energy vehicles have been modified (see 5.1.2; 5.1.2 of Edition 2014);

Introduction
This standard is an important measure for the implementation of the Plan for the Medium- and Long-term Development of the Automobile Industry. It aims to promote the development and application of advanced energy-saving technologies in automobiles of China, continuously reduce the fuel consumption of passenger cars in China, and promote the rapid and healthy development of the new energy automobile industry, so as to reduce the average fuel consumption of passenger cars in China to about 4 L/100 km by 2025, corresponding to approximately 95 g/km of carbon dioxide emissions.
To encourage the development of new energy vehicles, concessions are made in the determination up to the year 2025 of the fuel consumption and the corporate average fuel consumption (CAFC) for passenger cars of battery electric vehicle (BEV), off-vehicle-chargeable hybrid electric vehicle (OVC-HEV), fuel cell vehicle (FCV) types.
To encourage the development and application of energy-saving technologies for automobiles, this standard allows to reduce the fuel consumption of vehicle type in CAFC calculation based on the energy-saving effects, in line with the principle of quantitative evaluation, for energy-saving technologies or devices that demonstrate obvious effects in practice which, however, cannot be reflected, or fully reflected, by existing test methods.
Fuel consumption evaluation methods and targets for passenger cars
1 Scope
This standard specifies evaluation methods and targets for fuel consumption of vehicle type and corporate average fuel consumption (CAFC), production conformity and implementation date for passenger cars.
This standard applies to any Category M1 vehicle with a maximum design gross vehicle weight up to 3500 kg , including vehicles capable of working with gasoline or diesel fuel, battery electric vehicles, fuel cell vehicles, and vehicles capable of working with gas fuels, alcohol and ether fuels .

3 Terms and definitions
For the purposes of this standard, the terms and definitions specified in GB/T 19596 as well as the followings apply.
3.1
fuel consumption of vehicle type
combined fuel consumption of a certain vehicle type determined according to the prescribed method
3.2
average fuel consumption of vehicle fleet
average fuel consumption of a vehicle fleet calculated with the number of vehicles weighted based on corresponding to the vehicle type
3.3
corporate average fuel consumption
CAFC
average fuel consumption of vehicle fleet calculated with the fuel consumption of passenger car types produced or imported by a corporate weighted based on the corresponding production or import volume of the year
3.4
corporate average fuel consumption target
TCAFC
average fuel consumption of vehicle fleet calculated with the fuel consumption target of a passenger car type produced or imported by a corporate weighted based on the corresponding production or import volume of the year
3.5
off-cycle technology/device (OCT/OCD)
technology/device that has obvious energy saving effect in actual use, which, however, cannot (completely) be measured by existing test methods
4 Evaluation methods and targets for fuel consumption of vehicle type
4.1 Determination of fuel consumption of vehicle type
4.1.1 For gasoline, diesel, bi-fuel and dual-fuel passenger cars, the fuel consumption of vehicle type shall be determined using the Worldwide Harmonized Light Vehicle Test Cycle (WLTC) according to GB/T 19233.
4.1.2 For OVC-HEV and non-OVC-HEV passenger cars, the fuel consumption of vehicle type and the electricity consumption shall be determined using the Worldwide Harmonized Light Vehicle Test Cycle (WLTC) according to GB/T 19753. For OVC-HEV gasoline passenger cars, the electricity consumption shall be converted to gasoline fuel consumption according to GB/T 37340. For OVC-HEV diesel passenger cars, the electricity consumption shall be converted to diesel fuel consumption according to GB/T 37340. Up to 2025, the fuel consumption converted from electricity consumption is taken as zero 1).
4.1.3 For BEV passenger vehicles, the electricity consumption shall be determined according to GB/T 18386 and converted to gasoline fuel consumption according to GB/T 37340. Up to 2025, the fuel consumption is taken as zero .
