Chery As Technology A Goliath 7 Conquering Gobi and Media

Just a few days ago, news that a production car won the championship in the ring tower broke the circle of friends. Chery’s Ruihu 7 was a pure production model that not only successfully completed a race that was usually completed by only modified cars. And won the championship in one fell swoop. This kind of hard work was surprising, but even more rare was that we actually experienced the off-road performance of the Tiger 7 on the ground. After a cross-country track driving close to the ring tower and a normal road test drive, a car media expresses its appreciation for the excellent performance of the Tiger 7.

In fact, this experience event was the final race for Chery’s “Running Tigers 7! I was the Driver Challenge Camp” organized specifically for Tiggo 7, and it was with us that we were driving Tiggo 7 and 30,000 of them from across the country. Stand out of the 30 cars. The model we experienced was just a short time after it was launched, namely, the Tiger 7Sport model equipped with a 1.5T engine and a 6-speed dual-clutch gearbox. Whether it was a cross-country track race or a road test drive, the vehicles were all without modification. The original production model.

Powerful and full of 5 people speeding up easily

Tiggo 7 This 1.5T turbocharged engine, codenamed E4T15B, is a new engine optimized by Chery on the basis of E4T15, with a maximum thermal efficiency of 37.1% of the world's leading power, and a maximum output power of 108kW (liters) of the maximum power of the engine. 72kW/L), 210Nm maximum torque (140Nm/L rise torque). Thanks to its great lightweight design, the Ricoh 7Sport has a compact mass of only 1350kg, which is 200-300kg lighter than its competitors. Therefore, its ton power is 75kW/T, which is also better than most competing models. .

With a 6-speed dual-clutch gearbox with a transmission efficiency of more than 90%, the performance of the Tiger 7Sport is far better than what we see after the 1.5T engine displacement.

For double (driver + navigator) track driving, this kind of power is actually excessive, because cross-country roads are covered with sand and stones. Excessive engine output can easily lead to wheel slippage, especially for the Tiger 7Sport. Model. But even so, in the cross-country track, the Tiger 7Sport acceleration is still relatively fast. Compared with the fine cars, the driving performance of the Tiger 7Sport is significantly lighter.

On the pavement, the performance of the Tiger 7Sport is meaningful to consumers. Due to the improper operation of some of the players in the competition, some of the cars were damaged. We could only use one of the 4 or 5 media to fly a 7Tiger. Even so, the performance of the Tiger 7Sport was very surprising.

The first is that the acceleration capability is far beyond expectation. On a straight and windy road, the Tiggo 7Sport can guarantee a sustained and stable acceleration performance before 80km/h, and there are even some feelings of pushing back in the first half. However, the accelerating ability will have more obvious attenuation after 120km/h, but the speed of the deep step on the accelerator will still rise faster.

The second is the extremely high speed. Although the extreme value of the Tiggo 7Sport is 220km/h, we have pushed the speed of the Tiggo 7 to 201km/h on a windy road.

All in all, as a home-use urban SUV model, the performance of the Tiger 7Sport is satisfactory, not only for daily use, but also for occasional small exercise.

Excellent gearbox matching, comfortable and comfortable

For the Chery's first-ever use of the six-speed DCT dual-clutch gearbox, the media in the line gave a very high rating. In a media opinion, it was the performance of the very few models such as the Civic.

Dual clutch is characterized by short shift time and high transmission efficiency. However, most double clutches on the market, especially the six-speed double clutch, have the problem of low speed and large shift delay. However, it is obvious that the dual clutches provided by the Tiger 7Sport have solved most of the above problems.

In the process of test drive, no matter whether it is cross-country driving or highway driving, there is no obvious setback in the shift of the Tiggo 7Sport. Although the shift reaction time is still slightly slower than the mature AT, it is better than Most double-clutch transmission models are now available.

After turning on the air-conditioner on an ordinary road for 1.5 hours at a speed of 60-80km/h, the Tiggo 7Sport's fuel consumption fell to 6.4L/100km. After continuing to drive for 1.5 hours, and after many parking breaks, the fuel consumption of the Tiggo 7Sport is about 7L/100km. We think this fuel consumption is also lower, which is slightly better than our expected performance.

High-speed stability, great wind, 200km/h, not floating

Due to the different design orientations of pneumatic/site and other aspects, people's high horse SUV models are generally not suitable for high-speed driving, but Tiggo 7 apparently does not believe this evil.

As mentioned above, we experienced the high-speed performance of the Tiggo 7Sport on the Gobi Highway where we did not see any cars and the winds above Grade 5, and we found that the high-speed stability of the Tiggo 7 was excellent, and the common high-speed overtaking speed was 160km/h. Within the vehicle, there will be no sense of instability. Even at a speed of 201 km/h, there is no significant difference in stability performance from 160 km/h. The stable driving performance guarantees the driver's high-speed driving confidence.

Such excellent high-speed performance proves the strength of Tiggo 7Sport in site design. Chery said that the Tiger 7Sport has optimized its steering performance, and the steering assistance of the new car is more stable than the old models while ensuring the ease of use of the steering and the assistance is more reasonable.

In the cross-country track, the writer's feeling is that the Tiggo 7Sport is very easy to navigate, for example, the directional accuracy, and the steering wheel will not appear obvious thug problem, the direction is always stable, the vehicle has shown a good drive.

Comfort improves noise, vibration performance is better

In the test drive of the manual Tiggo 7 last year, the author made a very high evaluation of the noise and vibration performance of Tiggo 7. The new Tiggo 7Sport was tested on the Gobi Beach this time, and its NVH performance has been significantly improved.

The author can obviously feel the improvement from the vibration performance of the back row. The high-speed driving of the vehicle on paved roads has very limited subtle vibrations that can be felt by the rear passengers. Even with careful and sensible feelings, subtle vibrations can be completely ignored and the ride comfort of the rear seats is significantly higher than that of the old models.

In respect of noise, we found that even when driving at high speeds of 120km/h, the noise in the vehicle will not affect the communication between the occupants, even the front and rear rows of exchanges will not affect the occupant's rest. There will be a sense of fatigue.

Competition vehicle was opened with Toray Tiger 7Sport reliability

In the cross-country driving experience, Chery arranged new cars for the Bo X and GXX competition vehicles as a comparative test drive model for the media. Every media involved in the experience needs to select a competition vehicle at the timing point of the track 2 to change the driving experience. The racing vehicle drives a cross-country section with a length of about 1km and a lower difficulty.

However, not all media have completed this experience because one of the competing vehicles failed to continue driving after being tested for several times.

This episode instead shows the reliability of the Tiger 7Sport. In addition to damage to some models caused by improper driving of the racer, such as suspensions, tires, etc., the participating Tiger 7Sports have endured extreme violence driving by 50 drivers and nearly 40 media on the Gobi Beach at 50°C. In the second day of road driving, these models did not have any problems, and there were no common minor problems such as abnormal noise.

The most direct example is that some media have been worried that the dual clutch of the Tiggo 7Sport will not be tormented. However, in the Gobi beach where the temperature exceeds 50°C, regardless of the violent driving on a cross-country track that lasts one day, or the average driving speed of 160km/h on a paved road and the extreme speed of 201km/h, the two clutches of the Tiger 7 are diligent. No failure occurred. Only after high-speed extreme driving did the driver's media respond to the gearbox with a slight reaction to dullness and suspected of overheating, but there was no actual test data. The vehicle can also continue normal driving.

Experience summary

Chery has always shown people in a low-key image of engineers. Its new products have once again deepened my impression of Chery. In fact, relative to the value of color, configuration, etc., the above-mentioned engine, transmission, controllability, stability, NVH, and reliability are often referred to as “invisible places” and are often self-owned brands. Relatively weak place. In contrast to other independent brands that have invested heavily in their face value and configuration, Chery has been working hard at "invisible places." The performance of Tiggo 7Sport in these invisible places shows that Chery’s efforts are paying off, and Chery has also secured its status as a domestic automobile circle technology.

Under the background of increasingly fierce market competition and increasingly mature consumers, Chery's deep plowing of technology is the only way to break through the restrictions of joint venture brands and realize the leap-forward development of independent brands. With products with superior quality such as Tiggo 7 gradually embarking on the market, Chery will also lead its own brand to gradually change its brand image and allow consumers to have a brand new understanding of their own brands.
