Some people think that hybrid vehicles are only a transitional product. The ultimate goal of the development of new energy vehicles is electric vehicles. Therefore, China should cross hybrid power to directly develop electric vehicles and realize overtaking. This is not the case now. The "12th Five-Year Plan" (Summary) for the development of electric vehicle science and technology released by the Ministry of Science and Technology pointed out that the three types of electric vehicle technology, pure electric, hybrid, and fuel cell, have their own optimal models. For short-distance travel needs, small pure electric vehicles can be used; for long-distance travel needs, hybrid vehicles, plug-in hybrid vehicles or fuel cell vehicles are mainly used. The battery of medium-sized electric vehicles such as the BYD E6 is close to 500 kilograms, and it occupies most of the space in the car. Therefore, it is not advisable to use the pure electric mode in medium-to-large vehicles, and only use hybrid power.
In the past, the prices of hybrid vehicles were relatively high and have now changed. If the second-generation Prius uses a 1.5-liter engine, the starting price in China is 259,800 yuan; the third-generation Prius uses a 1.8-liter engine; the third-generation Prius in the United States has a retail price of 27,000 US dollars, equivalent to 170,000 yuan. Diversified. At present, the lowest official price in the country is 229,800 yuan, the highest price is 269,800 yuan, and online merchants offer 169,900-26,800 yuan. In addition, hybrid vehicles cannot make horizontal comparisons based solely on engine displacement. For example, the total power of a 1.8-liter hybrid car is equivalent to a 2.0-liter sedan, and the fuel consumption is lower than that of the second generation. As a result, the price gap is much smaller.
The United States has established a credit line for each qualifying hybrid vehicle. The credit line is lower than the electric vehicle (up to $7,500), and the Prius is $3,150, but this tax credit will go with the hybrid car of the car company. Quarterly sales reached 60,000 units and above, and began to decrease. There was no tax incentive from the sixth quarter. For example, if an American buys a Prius in July-September 2006, he will receive a $3150 tax credit, and no tax credit will begin on October 1, 2007. Relatively speaking, domestic subsidies for 3,000 yuan for hybrid vehicles are still too low, at least 20,000 yuan -30,000 yuan. Subsidies are best used for tax cuts. It is not a good idea to give money directly.
Many people think that hybrid cars can't afford to save more than oil prices, and they don't think the economy accounts will come. The average third-generation Prius fuel consumption announced by the United States is 4.7L/100km, 3.9L/100km in the United Kingdom, and 4.3L/100km in the Ministry of Industry and Information Technology. In comparison, the 2.0L sedan has a fuel consumption of 5-6L per hundred kilometers on the expressway, some 7L, and a congested road 8-12L, with an average of 6.5-9.5L. When the hybrid power is calculated at 4.5L/100km, the fuel saving rate can reach 30%-50%. In a competition in 2006, some Prius oil (45L) ran 1227.5 kilometers (of course, high-speed working conditions are mostly); shortly before friends in Hangzhou to participate in the Beijing auto show, Lexus CT200h a box of oil ran 1240 kilometers, the record is still Very impressive. Many people test drive hybrid cars. A box of oil can easily reach 1,000 kilometers. Plug-in hybrid cars can also add the added mileage after the battery is fully charged.
The advantages of hybrid vehicles are not only fuel saving, but also environmental protection. When the car is idling, the concentrations of exhaust gas CO and HC are high. As the speed increases, the concentrations of CO and HC decrease (contrary to the situation of NO2, the speed increases emission concentration increases), and some European cities have requested to turn off the engine when parking. Hybrid vehicles do not have idling conditions and start using electricity at low speeds, which can significantly reduce pollutant emissions. In a big city like Beijing, the average speed in the center area is 19.7 km/h. Some people predict that the speed will be reduced to 15 km/h, and PM2.5 will inevitably increase dramatically. At this time, the advantages of hybrid power can be revealed.
