2. Selection criteria

To be selected in the Topten product list, the Green Rating of the car should not be lower than the following values:

Category Cylinder capacity (L) Green Rating
Mini Cylinder capacity<1.0L ≥68.1
Small 1.0L≤ Cylinder capacity<1.3L ≥65.2
Compact 1.3L≤ Cylinder capacity<1.6L ≥67.1

Upper middleclass 2.0L≤ Cylinder capacity<2.5L ≥53.7

3. Terms

Fuel Cost: The cost of the fuel consumed by the car running 100,000 kilometers. It’s calculated based on the Composite fuel consumption per 100 kilometers. The price of the petrol is set at 7.8 RMB per liter. Unit: RMB.

Price: The reference price from the manufacturers and online website. For the actual price, please inquiry the sellers directly. Unit: 10,000RMB.

Green Rating: A comprehensive index based on the total life cycle energy and environmental impacts of the vehicle. The Green Rating combines air pollutant health impacts and greenhouse gas impacts into a single score ranging from 0 to 100. The higher a vehicle’s green rating, the more environmentally-friendly it is. The Green Rating methodology was developed by the Vehicle Emission Control Center, Ministry of Environmental Protection, in conjunction with the Innovation Center for Energy and Transportation. For the full text of the evaluation methodology will be available on the internet soon.

Composite fuel consumption: Fuel consumption for driving 100 kilometers over mixed city and highway driving, as specified in GB/T 19233-2008. Unit: L/100km. Note: fuel consumption is measured according to controlled and repeatable test conditions. Actual fuel consumption will vary greatly depending on driving style and many other factors.

Highway fuel consumption: Fuel consumption for driving 100 kilometers in a highway driving condition as specified in GB/T 19233-2008. Unit: L/100km.

City fuel consumption: Fuel consumption for driving 100 kilometers in a city driving condition as specified in GB/T 19233-2008. Unit: L/100km.

Cylinder capacity: Cylinder capacity is the volume swept by all the pistons inside the cylinders of an internal combustion engine in a single movement from top dead centre to bottom dead centre.It is the indicator to show the capacity of the engine. Many engine related performance indicators are closely related to cylinder capacity. According to the new China subsidy program for fuel efficiency and small cylinder capacity cars, if the car with the cylinder capacity below 1.6 liter meets some fuel consumption standards, the purchasers will get subsidy. It is measured in cm3 for more precise Unit: cm3.

Fuel: Fuel with which the results of the rating have been reached: petrol, diesel or hybrid.

Power: Unit: kW.

Emission standard: The tailpipe emission standard to which the vehicle is certified. The emission standard sets limits to the amount of pollutants released to the environment. Currently, National Standard III is the minimum standard nationwide. The higher a vehicle’s emission standard, the less environmental pollution.

Transmission: Mechanism of the car’s gearing system. It mainly includes: Automatic Transmission (AT), Manual Transmission (MT).

Total weight: The weight of a fully equipped empty car. Unit: kg.

Seats: Maximum numbers of passengers the car can carry.
