"range-extended vehicles have both the user experience advantages of pure electric vehicles, which are environmentally friendly and powerful, and the advantages of traditional internal combustion engines in terms of range, so they are more popular among consumers."

this sentence came from ma jing, professor and doctoral supervisor at chang'an university at the "top of kunlun" extended-range technology development forum on september 13.

this statement is the consensus at present, but if it was said a few years ago, it would definitely cause heated discussion.

in 2020, stephan wöllenstein, then ceo of volkswagen china, even "blasted" extended-range power as "the worst option."

however, i believe everyone knows the story that followed. consumers who voted with their "wallets" chose extended-range models equipped with "bad" technology when purchasing a car. car companies led by ideal and wenjie achieved huge success in the market.

nowadays, all companies are working tirelessly to launch extended-range products on the market. new forces such as avita, zhiji, and xiaopeng are ready to launch extended-range models. even volkswagen, which looks down on this "backward" technology, has revealed that it will launch its own extended-range model next year.

last month, avita even held a separate press conference for the "kunlun range extender system" that will be installed on the avita 07 extended-range version, which shows their emphasis on extended-range technology.

so, what are the advantages of avita's kunlun range-extending technology, and what are its advantages compared with other range-extending technologies on the market? let's share some academic ideas.

"kunlun" extended range

according to avita's official statement, the kunlun range-extending system on the avita 07 has the characteristics of high efficiency, strong power feeding, and support for fast charging, which can achieve a user experience that is infinitely close to that of a pure electric vehicle.

the avita 07 is equipped with a 1.5t engine designed specifically for range extension, with a maximum power of 115kw, achieving a class-leading thermal efficiency of 44.39% and an oil-to-electricity conversion coefficient of 3.63kwh/l.

what’s even more interesting is that while this engine ensures strong data, it is also “not picky” and can run normally with 92-grade gasoline.

in comparison, many models of the same level can only "eat fine grains" and add 95-grade gasoline, so avita 07 also has certain advantages in terms of vehicle use costs.

in addition, the kunlun range-extended system of the avita 07 is also equipped with a generator with a peak power of 100kw and a continuous power output of up to 70kw; even when feeding power, the vehicle can still maintain near-full-charge performance.

when we test-drove other extended-range models, we had previously encountered a situation where the power dropped significantly after the battery was used up. the vehicle even had a bad experience such as poor power smoothness and throttle failure.

according to official data, the avita 07 can accelerate from 0 to 100 km/h with a full charge in 4.9 seconds, while in the feeding state it can reach 0 to 100 km/h in 5.8 seconds. it can still reach a top speed of 190 km/h, so you can have enough confidence even when traveling by car in areas without charging conditions.

having an excellent power generation device is not enough. avita officials also mentioned at the previous kunlun extended-range launch conference that this system will be equipped with a large 39.05kwh battery, which can achieve a comprehensive range of 1,150km and a pure electric range of 245km.

in addition, in terms of energy replenishment, the fast charging time required for other extended-range models of the same level is often around 30 minutes, while the avita 07 only needs 15 minutes. according to the currently popular calculation method, it has reached the 3c fast charging standard.

we are also very curious about the actual performance of the range-extending system on the avita 07. let's dig a hole here first. after the avita 07 is officially launched, autolab will borrow one to help everyone test it and see how its power feeding performance is.

range extender technology competition

we have selected several of the most mainstream extended-range suvs on the market and made a list, allowing them to compete on the same stage and have a showdown with data.

the competitors in this comparison include wenjie m5, ideal l6, leapmotor c11, lantu free and avita 07. we selected the highest configuration and strongest performance version of each model to compare their comprehensive strength.

the comparison dimensions include engine power, engine thermal efficiency, acceleration time from 0 to 100 km/h, and fuel consumption, to see who performs better in these key performance indicators.

the data comes from the official websites of various automobile companies and data from the ministry of industry and information technology.

1. engine power

the engine power will determine how quickly and efficiently it can charge the battery. higher engine power generally means the car can charge the battery faster when the battery is low, keeping the electric motor powering the vehicle.

it can be seen that avita 07 defeated several other competitors also equipped with 1.5t range extenders in this indicator and took first place.

more importantly, like the leapmotor c11 which uses a naturally aspirated engine, the avita 07 will be more economical in terms of car usage costs as long as it uses 92-grade gasoline.

2. engine thermal efficiency

the engine performance of the avita 07, which only needs 92 gasoline, is truly surprising, and it once again takes first place in terms of engine thermal efficiency.

the thermal efficiency of the engine will also directly affect the fuel economy and environmental friendliness of the vehicle. higher thermal efficiency means that more fuel energy is effectively utilized and less heat is wasted.

for new energy consumers, energy consumption level is a major consideration when purchasing a car, and this parameter cannot be ignored when purchasing a car.

3. acceleration time from 0 to 100 km/h

the m5 with rs in its name took first place in the parameter of acceleration from 0 to 100 km/h.

in a straight line, two-wheel drive can never catch up with four-wheel drive under the same conditions. it can be seen that the acceleration results of the four-wheel drive models in this test are basically at the level of 4-5 seconds, and the only two-wheel drive model, leapmotor c11, is nearly half the gap compared with the first place. however, considering the price, this is reasonable.

4. power supply fuel consumption

the fuel consumption after power feeding is an important indicator that reflects the working efficiency of the entire range-extended system, the design of the engine, and the overall energy consumption of the vehicle.

it can be seen that except for the wenjie m5 which has not announced this parameter, the fuel consumption of the ideal l6 and lantu free models are 6.9l/100km and 6.69l/100km respectively, the two-wheel drive version of the leapmotor c11 is 6.1l/100km, and the four-wheel drive avita 07's fuel consumption is even lower than that of the two-wheel drive leapmotor c11, reaching 6.08l/100km.

it can be seen that higher engine power and higher thermal efficiency bring advantages in energy consumption performance.

in addition to the above four indicators, parameters such as fast charging time and 0-100 acceleration performance after power feeding are also important factors in measuring the user experience of extended-range vehicles.

unfortunately, during the comparison process, we found that each company does not have a unified fast charging capacity range, and manufacturers usually do not publish the performance data of the vehicle under power feeding conditions.

but in fact, these data are also important considerations for our consumers when choosing a car. in the future, our "lab test" column will also test these indicators that affect the vehicle experience, especially the zero-to-hundred acceleration performance after power feeding, which users are more concerned about. friends are also welcome to continue to pay attention.

can you be "martial" or "literary"?

in fact, in addition to the kunlun extended-range technology just mentioned, the avita 07 has many other highlights, among which the one that attracts me the most is the "taihang intelligent control chassis".

the taihang intelligent control chassis of the avita 07 uses front double wishbone and h-arm rear multi-link independent suspension in hardware, and the material used is higher-strength and lighter aluminum alloy, which greatly reduces the unsprung mass and brings a better driving experience.

in addition, at the connection between the suspension and the body, the avita 07 also uses hydraulic bushing technology, which is rare in its class. it can better isolate the bumps and vibrations of the road, which will greatly improve the comfort of riding and driving in the car.

of course, "basic" configurations such as air suspension and cdc shock absorbers will not be absent. avita has piled everything it can on the 07 chassis.

nowadays, it is definitely not enough for a car to have "muscles" and good hardware. if a car wants to sell well, it must also be "smart" and its intelligence must keep up with the times.

let’s talk about intelligent driving first. as huawei’s “own son”, intelligent driving has always been avita’s traditional advantage. this time, 07 is no exception. avita 07 will also become the first model equipped with huawei qiankun ads 3.0 intelligent driving system.

the new ads 3.0 will unlock a new intelligent driving experience in all scenarios, all-weather, and end-to-end, with new features such as doubling the decision-making speed and being closer to human driving habits. it can realize new functions such as parking, omnidirectional collision avoidance cas 3.0, and remote vehicle moving.

in addition, the avita 07 will also be equipped with the hongmeng cockpit developed based on harmonyos 4. the screen layout is very similar to the previous avita 12, mainly consisting of a 35.4-inch 4k remote screen, a 15.6-inch central control screen and two 6.7-inch rearview mirror screens.

although there are many screens, they are arranged in just the right position so as not to block the driving view while achieving maximum versatility and playability.

we have previously experienced the performance of this cockpit on the avita 12, and the overall experience was very good. we believe that the new avita 07 will not disappoint us.

final thoughts

in general, the avita 07, which is about to be launched, continues its previous advantages in terms of intelligence, chassis materials, etc.

the new range-friendly models that "embrace" the fuel tank have made up for the range anxiety of pure electric models and given users more choices.

avita 07 has also officially started pre-sale, and now all it needs is an explosive price to impact the market.

at the end of the article, we also give a small preview. when this car is launched, our "lab test" will also borrow it and put it together with the most mainstream extended-range models on the market for a "big test". let's see if the strength of this kunlun extended-range car is really what it is.
