Hybrid electric vehicles (HEVs) combine fuel and electricity, with an electric motor providing auxiliary power for driving. In a HEV, the engine and generator work together; the engine operates when it is functioning properly.
So, which is better, a range-extended hybrid electric vehicle (REEV) or a hybrid electric vehicle (HEV)? To answer this, let's first understand the main differences between the two types of vehicles:
1. Hybrid electric vehicles have lower fuel consumption at high speeds and more stable overall fuel consumption.
Range-extended hybrid electric vehicles can achieve fuel consumption as low as 3-4 liters per 100 kilometers in urban areas, and can even run entirely on electricity without fuel. However, these vehicles are driven entirely by electric motors, and when driving on highways, the motors need to maintain high speeds for extended periods, which consumes a lot of electricity. As a result, the fuel consumption of range-extended hybrid electric vehicles on highways is generally more than twice that in urban areas.
In contrast, the fuel consumption of hybrid electric vehicles does not fluctuate much in urban and highway conditions. Under combined urban and highway conditions, the actual fuel consumption of hybrid electric vehicles can mostly be maintained at 5-6L per 100 kilometers.
2. Hybrid electric vehicles are cheaper.
Currently, there are nearly 80 hybrid electric vehicle models on the market, with most priced between 150,000 and 200,000 yuan. The cheapest hybrid electric vehicle costs just over 100,000 yuan, making it more affordable for consumers with limited budgets. Range-extended hybrid electric vehicles, on the other hand, are fewer in number and are mostly high-end models, with an average price exceeding 300,000 yuan, making them more accessible.
3. Hybrid electric vehicles have better quality and stability.
Hybrid electric vehicles (HEVs) and range-extended hybrid electric vehicles (REEVs) are both hybrid technologies with a certain history. However, HEVs have undergone a longer period of market testing, so they have an advantage in terms of quality and stability. Even if quality problems occur, the subsequent maintenance costs of HEVs are lower than those of REEVs.
4. Range-extended hybrid vehicles are eligible for green license plates.
Because range-extended hybrid electric vehicles (REEVs) have charging ports and a long pure electric range, they are classified as new energy vehicles and can directly obtain green license plates. They can also enjoy purchase tax exemption and new energy subsidies. Hybrid electric vehicles (HEVs), on the other hand, still fall under the category of gasoline vehicles and can only obtain blue license plates.
5. Range-extended hybrid electric vehicles have lower operating costs.
Although range-extended hybrid electric vehicles (REEVs) experience significantly higher fuel consumption when the battery is low or when driving on highways, they can operate entirely on electricity if the driving scenario is concentrated in urban areas. With similar daily maintenance costs, the overall cost of using a REEV is lower.
6. Range-extended hybrid vehicles have stronger acceleration performance.
Range-extended hybrid electric vehicles (REEVs) are driven entirely by electric motors, so they are typically equipped with high-power motors. Compared to the lower-power motors in hybrid electric vehicles (HEVs), REEVs offer stronger acceleration performance, giving drivers more confidence whether accelerating from a standstill or changing lanes to overtake.
