Wuling Xingchen is the second model under Wuling's Silver Label strategy and the first SUV. With its stylish and youthful styling, LING OS system, spacious seating space, the only FSD variable suspension in the 100,000-class class, and other highlights, as well as its top-end con

Fuel Consumption Test: Urban Road Conditions

For a hybrid model and a non-pluggable HEV model, fuel consumption performance is naturally the performance we are most concerned about. We conducted a real-life fuel consumption test on the Wuling Xingchen hybrid top-end version, which was divided into two working conditions: urban and high-speed, with driving distances of more than 100km each.

The urban route traveled a total of 110.3 kilometers, of which about 80 kilometers were urban main roads with dense traffic but basically able to drive at a moderate speed. 30 kilometers were busy urban sections, passing through many light-controlled intersections, and stopped and went. The overall road conditions during non-peak hours on weekdays are relatively smooth, with only a few main road junctions experiencing severe congestion, and the average speed throughout the journey is about 31km/h.

At the end of the city route, the fuel consumption indicated was 5.3 liters/100 kilometers. We filled up the car again, and it was the same jump. The actual fuel consumption is 6.96 liters, which translates into an average city fuel consumption of per 100 kilometers of of 6.31 liters, which is one liter different from the data shown on the table. Based on the current price of 92# oil at 8.29 yuan per liter, the Wuling Xingchen hybrid version costs 0.52 yuan per kilometer, which is about 30 cents less than a fuel vehicle with the same power level.

Fuel consumption test: high-speed road conditions

After the city route ended, we immediately started the high-speed route test with full fuel. Among the 102.5km high-speed route, about 100km is a toll highway. We drive at the highest speed limit as much as possible. The hybrid system spends most of the time in the state where the engine directly drives the wheels and charges the battery. The motor The auxiliary function is very limited, and the energy consumption level is theoretically higher than that in urban conditions.

At the end of the high-speed route, the indicated fuel consumption was 5.7 liters, which was slightly higher than the 5.3 liters indicated in urban road conditions. What was the actual measurement result? We flushed the car and filled it up with oil. The actual amount of oil was 6.56 liters, which is equivalent to 6.40 liters/100 kilometers. Calculated based on the 92# oil price of 8.29 yuan, it is 0.53 yuan per kilometer, which is basically the same as urban routes.

Fuel consumption test summary: As a compact SUV, the body size of Wuling Xingchen is not "compact", and the hybrid version weighs about 1.6 tons (about 100kg more than the fuel version). This 2.0L The hybrid system consumes just over 6 liters of fuel during stop-and-go driving in urban areas, saving at least 3 liters of fuel compared to a fuel vehicle with the same power level. In the case of high-speed direct drive, it is equivalent to a fuel vehicle. The single-speed DHT also makes its cruising speed relatively fixed and high, but the actual measured result of 6.4 liters is also very good.

Acceleration test

Hybrid models can be driven directly by the motor. Thanks to the full torque output characteristics of the motor, it has a brisker speed-up performance in the middle and low speed range than a fuel vehicle. Therefore, after switching to the hybrid system of Wuling Xingchen, the zero-to-zero acceleration performance is naturally worthy of discussion.

Turn off ESP and the air conditioner before conducting the fuel consumption test to limit the power as much as possible. Shift into S gear. At this time, the system will immediately start the engine and enter HEV mode. The engine and electric motor will output in parallel. The 100kW power-shaped battery will also reach the maximum discharge power, and the vehicle will enter the strongest power state.

During the 0-100km/h acceleration test, the front wheels of the Wuling Xingchen Hybrid experienced tire slippage that lasted for about 1 second at the moment of starting. This shows that the power of the driving wheels is quite strong. The starting posture is relatively calm, the head-up phenomenon is not obvious, the push-back feeling is strong in the early stage, and continues to weaken in the later stage. The entire acceleration process is smooth and natural, and the single-block structure also avoids power interruption when changing gears.

It can be seen from the test chart that due to tire slippage at the start, the power has a "landing" process within 0.5 seconds, and then explodes to the maximum G value, close to 0.6g, which gradually weakens to 0.2g as the speed increases. The whole process is very Smooth and silky, no big fluctuations.

Wuling Xingchen Hybrid’s measured zero-to-0-60 acceleration time of 8.17 seconds is in line with our expectations. It is not as fast as the official 7.8 seconds, but it is more than one second faster than the 1.5T fuel version. Compared with other 2.0L hybrids, It is a joint venture brand model, and its performance is also better. It can be considered impressive in front of the two hybrid giants Toyota and Honda.

Braking test

Braking performance is also one of the basic vehicle performance we pay attention to. Wuling Xingchen performed relatively average in the braking test at 100 kilometers per hour. First of all, when braking at full power, the front of the car sinks seriously, the front suspension is quickly compressed to the limit when the center of gravity shifts rapidly, the rear of the car is raised high, and the rear wheel grip is reduced, which further affects the braking effect. The original Giti Comfort F50 series tires are focused on comfort and are known for their cost-effectiveness. The 215mm tire width is not ideal, which also affects braking performance to a certain extent.

Judging from the test chart, the acceleration remains at a level of -0.9g during full braking, which is not very high and cannot reach above -1.0g. Fortunately, the braking force is released evenly throughout the entire process, and there is no slow response in the early stage or severe attenuation in the later stage.

The brake system hardware of the Xingchen hybrid version is the same as that of the fuel version. It uses a vacuum booster brake master cylinder , and a front ventilated disc rear solid disc. The tire model is also exactly the same, limited by cost, and The iBooster electronically controlled brake assist system is not used, so the braking performance is comparable to the fuel version, both at 41+ meters. Compared with the braking distance of several other joint venture hybrid SUVs of less than 40 meters, this result is indeed not outstanding.

Noise test

In terms of noise, as an economical hybrid model, you can't expect it to be equipped with soundproof glass and active noise reduction. However, the entire car is still covered by 42 acoustic packages, so the sound insulation performance is not sloppy. After our actual test of

, when the vehicle is stopped and in the EV state, the engine is not working. At this time, the noise value in the car is 37.8 decibels, which is quite quiet. When the engine is involved, the operating noise becomes more obvious and can be clearly discerned in the car, reaching 47.0 decibels.

After the vehicle started driving, the measured noise values ​​were 60.1 decibels, 68.3 decibels, and 74.2 decibels at 60km/h, 90km/h, and 120km/h respectively. Such values ​​are not beautiful, because the body shape is relatively square and the speed is high. Downwind noise has become the main source, but considering its positioning and price, this result is within an acceptable range and is basically equivalent to similar models.

LING OS voice interaction test

Wuling Xingchen is the first model of LING OS Lingxi system . This system is jointly developed by SAIC-GM-Wuling , PATEO , SPEED , iFlytek , etc. It is an open and intelligent ecosystem that will gradually cover all new Wuling vehicles in the future.

LING OS Lingxi system has OTA capabilities and can be continuously iteratively updated. In the future, it will develop into an ecosystem integrating intelligent network connection, intelligent driving, and intelligent terminals. However, it is still focused on the intelligent network connection level.

I have already experienced this LING OS system when I test drove Wuling Jiachen. It has fast cold start, smooth operation, reasonable interface UI and operation logic, easy to get started, and rich functions. It is also the first to be used in cars. The terminal has built-in NetEase Cloud Music.The Lingxi system

has been widely praised since its release. Especially in terms of voice interaction, its usability is even higher than some new brands with intelligent labels. It supports partitioned sound pickup (left and right), continuous dialogue, and visibility. Speaking, multiple command recognition, wake-up-free, customized wake-up words, 3D car assistant image, etc., the entire voice interaction experience is very natural and more emotional.

To this end, the author specifically focused on Wuling Xingchen’s voice interaction and scored it according to the voice interaction evaluation standards in the Geek+ ICT-300 smart cockpit evaluation system to see where it is on the ranking list.

Regular function implementation

The first is the implementation of regular functions, including four basic functions: air conditioning, navigation, car windows, and music. These are a piece of cake for LING OS, and the recognition is fast and accurate without any difficulty. Of course, its capabilities don't stop there. For example, wipers, , sunroof, ambient lights, vehicle settings, etc. can all be operated through the voice system. Basically, you can only use your mouth while driving without using your hands. In addition to covering enough functions,

also has a very fast response speed, fast recognition and execution, and can basically answer questions in seconds. However, it also has certain speaking speed requirements for command input. If you pause slightly while speaking, the system will immediately enter the recognition process, resulting in incomplete command input and the need to operate again. Of course, this is also the case in many models. question. Therefore, during voice interaction, it is recommended to think about the sentence you want to say first, and then say it all at once to improve the recognition success rate.

Speech error correction ability

In the error correction ability test, we used three sentences with obviously deviated pronunciation for testing. The test was to test the in-vehicle system's ability to understand and correct non-standard Mandarin .

After testing, the system can recognize the two instructions with a strong Cantonese accent, "Open the car window" and "Navigate to the Bund". For the more difficult "I want to eat McDonald's ", it can recognize it as "I want to go to Macau." "Donglou" has a medium error correction ability, which is on par with most new power models.

Semantic association multiple recognition

This part of the test tests whether the vocabulary of the speech system is large enough, and whether the semantic understanding without any functional direction is accurate, such as "I am hot" and "I want to eat McDonald's". Whether it can be implemented clearly but without mentioning key words such as "air conditioning" or "navigation" in the statement.

After actual testing, the Lingxi system can easily complete the first four commands. This is also the limit of the ability of most car voice systems at present. What surprises me even more is that it can implement cross-functional dual commands, such as "Turn down the temperature." And open the passenger window."

In fact, even many new power brand models with the "smart" label cannot execute such instructions. However, Wuling's LING OS system is said to be able to implement ten commands, which means that ten commands can be executed at once. Say it, and the system can recognize all of them and complete all instructions at the same time. However, the system failed to successfully execute the command "temperature adjustment + navigation".

Overall, the voice system of this LING OS Lingxi system has a total score of 30 points. In the voice interaction part of our Jizhi + ICT-300 smart car evaluation system, it is the same as Jikrypton 001, ideal ONE, small Models such as Peng P7 tied for fifth place, better than Weilai ET7, BYD Han and other models.

What’s interesting about Wuling’s hybrid technology?

1. P1+P3 mainstream hybrid structure

Wuling Xingchen’s hybrid system adopts the current mainstream “P1+P3 dual motor series and parallel” route, which can realize four driving modes of pure electric, series, parallel and direct drive. The P1 motor is mainly used for starting and generating electricity. The P3 motor replaces the traditional gearbox as a drive motor. Its maximum torque reaches 320N?m, achieving very strong starting power.

2. The world's first electromagnetic single-speed DHT

Traditional hydraulic DHT has oil loss problems. The oil becomes viscous at low temperatures, causing switching delays when electric drive to direct drive.Wuling's hybrid system uses the world's first electromagnetic DHT, which adopts a high-efficiency electromagnetic combination method to achieve ultra-high speed control accuracy and ultra-fast switching speed, bringing faster and smoother driving response.

Clutch disengagement

At medium and low speeds, the electromagnetic clutch is in a disengaged state, and the drive motor is directly connected to the wheel end to drive the vehicle, and the engine only generates electricity; at high speeds, the electromagnetic clutch is connected when energized, accurately and quickly realizing electric drive to direct drive , the engine is directly connected to the wheel end to drive the vehicle, providing silky smooth driving control like a tram at full speed.

Clutch combined with

Some manufacturers' hybrid special transmissions (DHT) will adopt a multi-speed structure, such as the 2-speed DHT of Great Wall Lemon Hybrid, and the 3-speed DHT of Geely and Chery . The multi-speed structure can further Improving the engine's operating efficiency and making the direct drive range wider will also increase the weight, volume, and cost. If the adjustment is not good enough, the smoothness will be greatly compromised when changing gears. Wuling Hybrid chooses a single-speed structure. On the one hand, it can ensure the smoothness of power. On the other hand, it also reduces hardware costs and improves reliability. For a hybrid SUV that takes a people-friendly route, this approach is obviously more sensible.

3. 2.0L hybrid dedicated high-efficiency engine

Wuling Xingchen Hybrid is equipped with a 2.0L Atkinson hybrid dedicated engine, with a maximum thermal efficiency of 41%. This value is considered leading among hybrid technologies currently on the market. The engine has a rated power of 100kW and a maximum torque of 175N·m ( net power 2kW, net torque 168N·m), which not only meets the function of efficient power generation in urban areas, but also ensures that it is powerful enough for high-speed direct drive.

This hybrid special engine has a number of fuel-saving technologies, such as EGR (exhaust gas recirculation) system and independent cooling system technology, as well as low damping springs, low tension piston rings , piston low friction coating, etc.; it also applies medium Built-in hydraulically driven dual VVT (intake and exhaust valve continuously variable timing) technology shortens the entire vehicle's oil and gas circuit and improves idling stability.

4. Three-power technology

Battery: Wuling Xingchen is equipped with a 1.8kWh high-power ternary lithium battery with a maximum discharge power of over 100kW, achieving a stronger electric driving experience. The battery core adopts an ultra-thin coating process and supports more than 50,000 high-temperature and high-rate cycles, which improves the safety, power density and cycle life of the battery, and supports ultra-low temperature cold start of -30°C.

motor: adopts a "P1+P3 dual motor" structure. The maximum torque of the drive motor reaches 320N?m. It starts with full torque output and its power performance is comparable to that of a 2.0T engine. It has an ultra-high peak efficiency of 97% and is more energy-saving. At the same time, it adopts low harmonic content NVH low-noise and mute technology to bring users a quieter driving experience.

electronic control: uses a highly integrated dual motor controller , which can realize OTA remote flashing function, and the algorithm adapts to different load requirements and application scenarios. The power module is equipped with a new generation of DrivePack automotive-grade module, which is one of the most advanced automotive-grade IGBT power modules in China and has the characteristics of ultra-low loss, ultra-high output power, and ultra-high reliability.

is priced at a price close to the people, but the configuration is sacrificed?

Compared with the fuel version of the Wuling Xingchen top model, the top model of the hybrid version only costs 10,000 yuan more, and it also uses a higher-cost rear multi-link independent suspension. Is this offset by reducing configurations? Woolen cloth? Let’s take the top and sub-top configurations of the fuel version and hybrid respectively to compare the configuration differences. The top-spec 1.5T Xingyao version of the

fuel version is priced at 99,800 yuan. Compared with the 109,800 yuan top-spec hybrid 2.0L DHT electric version, it has more features: spare tire, air curtain, variable suspension, automatic air conditioning, PM2.5 filter device, ambient lighting, rearview mirror electric folding , etc., and is equipped with 9 speakers.

The top version of the hybrid version is equipped with multi-link rear independent suspension, automatic driving locks and 6 speakers, while side curtain airbags + panoramic sunroof + crystal electronic gear lever will cost 4,000 yuan as an option.

In the sub-top version, the 1.5T Xinghui version has more features than the 2.0L DHT electric version: side airbags , spare tire, Bluetooth key, remote start, rear radar , variable suspension, single sunroof, LED automatic headlights, four windows with one-button lift (with anti-pinch), sensor wipers , 12V power supply in the trunk, and 6 speakers.

The hybrid version only has an automatic locking function and is only equipped with 4 speakers. The 10.25-inch large screen + LING OS system + crystal electronic gear knob costs 2,700 yuan as an option.

Although from the price point of view, the hybrid version seems to be only 10,000 yuan more expensive than the fuel version, but after such a comparison, you will find that in fact, in order to keep the hybrid version within a price range that is close enough to the people, the configuration There is a certain amount of sacrifice involved.

However, Wuling’s approach is advisable. After all, the cost of a set of hybrid technology is not low. It makes sense for price-sensitive consumers to reduce vehicle prices by reducing some unnecessary configurations.

Power experience

Wuling Xingchen hybrid version uses a 2.0L Atkinson cycle naturally aspirated engine. Officially, the thermal efficiency of this engine has reached the same 41% as Toyota, which is a little higher than Honda's 40.6%. . The engine output data is 136 horsepower and 175 Nm, which is a bit lower than the Toyota C-HR engine (145 horsepower, 188 Nm) that also uses a 2.0L hybrid system, but the power and torque of the drive motor are higher than The C-HR’s 109 horsepower and 202 Nm are much higher.

Different from the THS hybrid system on the Toyota C-HR dual engine, Wuling Xingchen’s transmission mechanism is not an E-CVT, but a single-speed DHT structure with an electromagnetic control clutch. The biggest difference between it and THS is that it can realize engine direct transmission. Drive, the entire system is closer to Honda's i-MMD system.

In fact, some domestic manufacturers have already used second-speed or third-speed DHT, but the Wuling R&D team found that when users use the vehicle, 95% of the time they drive below 80km/h, and urban driving takes up all the time. For 90% of the driving time, for the DHT system, a single gear can meet most usage scenarios. It can also significantly reduce R&D costs, lower the selling price, and avoid gear shifting frustrations.

In actual driving, you can really feel that the power output of this set is very smooth and silky, and it is also very quiet when driven by pure electric power, which is what a hybrid model should be. The engine will intervene when it is above 35km/h, and the noise it intervenes is also very low. You can't feel it without looking at the tachometer . Unless you give the oil a big kick, the engine speed suddenly soars to more than 3000rpm, otherwise it will not be special. It's hard to notice if you pay attention. When the

Xingchen hybrid version is in D gear, the power output is relatively soft, and even makes people feel a bit meaty. It once made me wonder whether it is really driven by a motor. But when you shift it into S gear, it changes its personality directly. The back feeling of pushing the fuel at low speed is super strong, and it is very appropriate to use "moving like a rabbit". Wuling Xingchen's official 0-60km/h acceleration time is only 3.2 seconds. The 100kW power battery and the 320 Nm drive motor are all responsible for such a rapid acceleration.

This system can realize multiple modes of pure electric driving, series drive, parallel drive, direct drive + charging, kinetic energy recovery, and parking charging. Through the energy monitor, you can see that when starting gently, the vehicle is completely driven by the motor. When the vehicle speed reaches more than 35km/h, the engine will intervene. At this time, it is in series mode. The engine drives the generator to generate electricity, and together with the battery, supplies power to the drive motor. When the vehicle speed reaches 80km/h or above, the engine will enter direct drive mode. And when you step on the accelerator deeply to accelerate, the engine and the drive motor will drive the wheels together, which is in parallel mode.

Limited by the fixed transmission ratio of single-speed DHT in direct drive, the top speed of Wuling Xingchen hybrid version is only 145km/h, but this is enough for China's road environment. Overall, the hybrid system of Wuling Xingchen is quite powerful and worry-free in daily driving. Especially in S gear, driving has the pleasure of a tram without the anxiety of a tram.

Steering feel

The steering feel of Wuling Xingchen hybrid version is relatively light. It is very easy to drive at low speeds and the feedback texture is also relatively good. When driving on the highway, the speed-dependent gain effect is obvious, and the driving is not drifting. However, there is a small gap in the steering wheel. If you are driving intensely, you will feel that the front direction of the car is a bit slow, which is not smooth enough. Of course, for an SUV that focuses on family comfort, this is not a flaw.

Chassis Suspension

The vibration filtering performance of the entire chassis is also relatively good. When passing through large potholes, the shock absorber can fully resolve the impact, and the vibration filtering texture is also relatively high-quality. It is very integrated and will not give people a loose feeling. . However, the suspension has slightly more aftershocks. Although it can effectively reduce the impact feeling when passing through speed bumps, the suspension rebound is not crisp enough and there will be short-term continuous oscillation, even on some very flat but hard cement roads. There will be a bumpy feeling, and there will be obvious small movements when passing through road joints. There is still room for optimization in terms of comfort.

Summary

Wuling Xingchen is currently the cheapest hybrid model on sale, and the top-end price of less than 110,000 is indeed affordable enough. This allows consumers with limited budgets to enjoy the benefits of HEV hybrid models at a lower threshold. . The silver-labeled Wuling Xingchen has a certain improvement over the red-labeled Wuling models in both appearance and interior quality. Coupled with its good performance in chassis and control, as well as the arrival of hybrid power systems, It can be said to be extremely competitive in the 100,000-class SUV market. In addition to HEV, PHEV version is also coming soon. I believe that Wuling, a hybrid hybrid that serves the people, will bring us more surprises in the future.
