How did Chevrolet Pioneer RS, whose measured fuel consumption is comparable to that of a 2-ton car, do it?

Easy car originality: In many people's inherent impression, American cars are synonymous with fuel consumption. When you see an American medium and large SUV with a length of 5 meters and a weight of 2 tons parked in front of you, do you dare to believe that it can achieve the ultimate fuel consumption of 5.2L/ 100km, and the average daily fuel consumption can be maintained at around 7L/ 100km?

On a sunny morning, we started this verification trip. The protagonist is seven medium and large SUVs listed last year: Chevrolet Trailblazer. Friends who want to know other information about this car, my colleague has introduced it in detail before: first take the "force" to test drive Chevrolet Pioneer RS?

This experience has two key points: one is how low is its fuel consumption? Another is to what extent has its MyLink+ intelligent vehicle system developed after OTA upgrade?

The model of our test drive this time is the Chevrolet Trailblazer 650T RS 9AT dual clutch four-wheel drive 7-seat engine version, which belongs to the top model. The whole system adopts 2.0T+9AT powertrain, which meets the national 6B emission standard. The maximum power is 237Ps and the maximum torque is 350 Nm. Its maximum torque and speed range is between1500 rpm and 4000 rpm, and 95 # gasoline needs to be added.

Let me talk about the technical highlights of this powertrain. The biggest highlight is Tripower's three-stage intelligent cylinder changing technology, which can intelligently select and adjust the valve lift in real time according to the working conditions, and smoothly switch between the three working modes of "four-cylinder surge", "four-cylinder high efficiency" and "two-cylinder smooth operation". The matching 9AT gearbox is equipped with a variety of products of SAIC-GM, which has a wider speed ratio range and finer gear allocation, and can shift 9 gears within 95 km/h.

From the book, there is nothing wrong with this powertrain, there is no three-cylinder engine, there is no double clutch, and it is still a big displacement. Except that the cost of burning No.95 gasoline is slightly higher, it should be acceptable to everyone. This time, we drove all the way from Boruishun and Chevrolet 4S store in Haidian District to Tongzhou Grand Canal Park and then returned to the starting point after lunch break. Finally, the actual fuel consumption performance of this car is judged according to the apparent fuel consumption performance.

There are two passengers in our car, walking all the way and returning all the way. The selected route is mainly the unobstructed Sixth Ring Road, with some normal road conditions and congested road conditions in the middle. The journey is 86 kilometers and the return journey is 80 kilometers. The final apparent average fuel consumption is 5.7L/ 100km. Under the nature of this competition, everyone will use various methods to reduce fuel consumption as much as possible. We looked up the fuel consumption scores of previous test drive media, and the lowest score was 5.2L/ 100km, while the apparent fuel consumption of normal vehicles was about 7L/ 100km under the comprehensive working conditions of most high speed, a few urban areas and a little congestion. For reference, the comprehensive fuel consumption of the Ministry of Industry and Information Technology of this top model is 7.

To tell the truth, the result is still surprising. You should know that a car has its own limits. Even if you try your best to control factors such as wind resistance, braking and throttle opening, the final result can't escape its own mechanical quality. As a 2-ton, square and medium-sized SUV, it is remarkable to be able to push the limit to 5.2L/ 100km. As the daily driving mode of our ordinary car owners, it is hard to say that the average fuel consumption is around 7L/ 100km.

Let me talk about my feelings from the driving process. First of all, when you are driving lightly, the gearbox is willing to actively upshift. You can definitely get the ninth gear within the officially declared 95km/h, and the upshift process is very smooth and almost imperceptible. In addition, this three-stage intelligent cylinder changing technology, we only use two modes of "four-cylinder high efficiency" and "two-cylinder smooth operation" almost in the whole process. Four-cylinder high-efficiency mode is realized with medium throttle in middle-high speed cruising state, while two-cylinder smooth driving mode is realized with small throttle in middle-low speed constant speed, deceleration or downhill driving state. However, under the condition of low speed and uniform downhill, the instantaneous fuel consumption can be obviously reduced, and it is difficult to feel vibration or feedback when the two cylinders in the car are closed, so the occupants in the car will not feel uncomfortable from the experience.

In terms of in-vehicle system, you have to admit that domestic brands are the best, and they are superior to joint venture brands and luxury brands in terms of functional richness, voice recognition ability and recognition logic. Recently, however, some joint venture brands have actively cooperated with Zhongke Company in this respect, and the overall level has surpassed Geely, Great Wall and other domestic excellent in-vehicle systems, such as the latest Dongfeng Da Yue Kia K5 and Beijing Hyundai Sonata.

The Chevrolet Trailblazer RS we experienced this time is not a new model, nor is it an annual modified model. It only upgraded the in-vehicle system MyLink+ on the current model and completed the update of 22 functions. After practical experience, it is found that the availability of the system has gradually become the mainstream level of intelligent vehicle-mounted systems.

Let's take a look at what has changed since the OTA upgrade. First of all, it deeply integrates the latest speech recognition technology in Iflytek. Thanks to Iflytek, the speed of speech recognition, the ability of natural semantic recognition and the richness of supporting functions have been significantly improved. Generally speaking, you only need to say "Hello Xiaoxue" to wake up the car system. You can also change the wake-up address according to your own preferences, such as "Hello Xiaoxue, can I call you silly goose", and then say "Hello Xiaoxue" to wake up the system. Then it supports continuous dialogue. You don't have to wake up "Hello Xiaoxue" separately every time there is an instruction input. You can find a gas station and navigate directly and continuously, but you still don't support functions such as opening the skylight and adjusting the electric seat.

Then there is the upgrade of navigation, equipped with the car version of Gaode map. This time, the function of setting routing points has been added. Firstly, the navigation route from A to B is set by voice control, and then route C is informed again, so that the setting of route points can be completed and the recommended route of the system can be changed.

After OTA, the system interface can support theme selection and there are more flat styles to choose from. In addition, the shortcut function card on the last page of the home page can be deleted by sliding up. Music-related functions currently support Himalayan and other built-in applications, but you cannot download Tik Tok, QQ music and other applications you want to use.

Summary: It is very necessary for the pioneers to improve the intelligence of the car system, which once again adds weight to the balance bought by young people. In addition, the performance of fuel consumption is also surprising, which has changed everyone's understanding of American fare oil.
