Enlarge the fuel tank, the whole downhill, known as a car with a range of more than 2,000 kilometers, is it greasy?

In the past, when new mobile phones were listed, they liked to run a score, but now when new cars are listed, they will run a battery life, and battery life has become a way for many new energy vehicles to show their strength.

When many new cars were launched, they began to claim that they could run 2,000 kilometers with full fuel and electricity. What is the concept of 2000 km? It's about the distance from Beijing to Guangzhou, is this really a car running with full fuel and electricity?

What cars claim to be able to run 2,000 km?

A few days ago, Xingtu Star Era launched a new medium and large SUV Star Era ET, which did some tests before going on the market, and after more than 40 hours of uninterrupted live broadcast, as well as under the harsh conditions of full load without turning off the ignition, with a comprehensive range of 2141.4 kilometers, it set a new record for the battery life of new energy vehicles in China.

Dongfeng Fengshen's first plug-in hybrid model, Fengshen L, is a "long-range intelligent hybrid SUV" with a pure electric range of 205km, equipped with a new generation of Mach electric hybrid PHREV hybrid technology, with an ultra-long range of 2,000km. Before the listing, 5 automotive media joined hands with Dongfeng Fengshen to launch a challenge of extreme endurance from Kunming, Yunnan Province to Wuhan, Hubei Province, and the official calibration of 1500km comprehensive range SUV with the longest mileage reached 2054km!

In addition, Geely launched a technology flagship SUV prototype - Galaxy Starship, tentatively named Galaxy L9, equipped with a new generation of Raytheon electric hybrid technology independently developed by Geely, the technology makes the engine thermal efficiency more than 46%, feed fuel consumption reduced to 2L, the official said that the vehicle mileage is more than 2000 kilometers.

The layman looks at the liveliness, and the insider looks at the doorway

The range of more than 2,000 kilometers with full fuel and full battery is not only a proof of the technology of the car company, but also can effectively alleviate the anxiety of battery life and bring lower car costs, which is the focus of the crazy publicity of the car company.

I have to say that "more than 2000 kilometers of endurance" is very exciting, which is very easy to break the cognition in the new energy vehicle market, a product point that is deeply rooted in the hearts of the people.

There is no doubt that it can be done with a range of more than 2000 kilometers, after all, now car companies are broadcasting the whole process of battery life challenges, and there are many eyes staring at the Internet. Generally, the vehicle is set off with full fuel and electricity, and the fuel tank and meter are sealed, and the vehicle is driven until it breaks down.

In fact, the big coffee has also participated in many brands of energy-saving competitions, including fuel, mild hybrid, plug-in hybrid, pure electric models and other competitions, which are not a lot of cats.

First of all, the time and place of the endurance test are very particular, and it is generally necessary to avoid severe cold and heat. Such extreme weather will have a great impact on the performance of the vehicle. For example, the ideal MEGA winter endurance test was previously arranged in Hainan, is there winter in Hainan? Nope!

Secondly, the location of the origin and destination points is also crucial. Some car companies set the starting point of the Endurance Challenge at high altitude and the end point in the plains. For example, the altitude of Xining city is 2,261 meters, and the average altitude of Yichang city center is 72 meters. The altitude difference between the two is more than 2,000 meters, and the downhill section is the majority, making it easier to achieve lower fuel consumption. It is no exaggeration to say that as long as the drop is large, the fueled Tesla can even be fully charged from the top of the mountain to the bottom of the mountain.

The test sections are mainly highways and national highways, so that the vehicle can travel at the most efficient speed of 60-80 km/h, and the hybrid system will automatically determine the best time to intervene. Avoiding congestion and traffic lights also allows the test to achieve near-minimum fuel consumption.

If the fuel tank is made larger, it can also run farther, for example, the fuel tank of Star Era ET has reached 67L, which is much larger than the 50L fuel tank of the average family car, and it already costs 550 yuan to fill up a tank of 67L.

The method of vehicle testing is very different from that of our daily driving. In order to achieve the lowest energy consumption, we will avoid turning on the air conditioner, while maintaining a constant speed of 60-80km/h, avoiding sudden braking and rapid starting, which is very different from the stop-and-go working conditions of our daily driving.

In the end, in order to achieve better results, sometimes they will even take risks to follow behind the big truck. The wind breaking of large trucks can effectively reduce wind resistance and save energy consumption, especially at high speeds to follow large trucks all the way at the most energy-saving speed, which is the most ideal driving state. We need to keep a reasonable distance between vehicles in our daily driving to avoid rear-end accidents.

Under these conditions, there are indeed many plug-in hybrid or extended-range vehicles, which can achieve a range of more than 2,000 kilometers with full fuel and full power. In the eyes of most people, a tank of fuel used to run a few hundred kilometers at most, but now it can run 2,000 kilometers, indicating that the energy consumption control level of the car and the increase in battery energy density have brought about an obvious improvement in fuel economy.

However, a range of more than 2,000 kilometers is actually a false proposition, which is the result of squeezing the vehicle and the driver at the limit. Can you drive without air conditioning? Can you be willing to be a big mom on the road? Can you guarantee that the road you drive will not be congested? With our daily driving habits and methods, the comprehensive range of full fuel and full power can reach 1500 kilometers, which is already very good, and the CLTC comprehensive range of most models is also calibrated at about 1500 kilometers, which is also the gap between theory and reality.

Write at the end

Whether it is a gimmick or a selling point with a range of more than 2,000 kilometers, it can indeed show that the current new energy vehicles have very obvious energy-saving advantages. For consumers who use cars frequently every day, they can really save travel expenses, especially those who run outside all year round and have an annual mileage of more than 20,000 kilometers. If you drive a few thousand kilometers a year, then the energy consumption of the car is not the first thing to consider.
