Recently, I took the WM EX5 purchased by drivers from a colleague for testing. As one of the first users to pick up the car, the EX5 400 innovative version has traveled nearly 60,000 kilometers in the three years since November 2018. When I used the car machine App self-test, I found that the software prompted that I needed to go back to the store for maintenance, and the cumulative mileage of the other long test car W6 of the driving Shipai was also nearly 10,000 kilometers, so I asked my colleagues to send the two cars together to the official after-sales service of Weima for maintenance.
Different from traditional car companies, WM's after-sales appointment service does not need to be contacted by phone, and the service options of the WM App and the car machine in the mobile phone can be directly clicked on the after-sales outlets that are convenient to go to, and even the specific date and time period of the store can also be checked on it, so that the maintenance workstation can be accurately reserved.
Before going, I thought that the appointment was just a process, who knew that after arriving at the store, I found the necessity of this link - from entering the reception area to leaving, for nearly three hours before and after, there have been Wei carriage owners coming to repair and maintain. I also asked the after-sales service specialist that on average they need to receive about 15 vehicles a day, and the situation is similar in other local stores. And this is still in a city like Chengdu, which has no license limit, and according to their understanding, in areas such as Beijing, Shanghai, Guangzhou, or Hainan, this data will be higher. It seems that I usually see a variety of WM models on the road is not the "maternity effect", and the after-sales busyness is enough to show that through more than three years of accumulation, the ownership of WM in the market is not low.
After completing some handover procedures, the service specialist of WM opened the W6 into the after-sales workshop. Here and the traditional fuel vehicle environment layout is basically the same, the whole feeling is still very clean and standardized, the biggest difference is that there is no pipe connected to the exhaust pipe of the fuel vehicle in the workshop of WM, and the inside can not smell the odor.
Although the W6 did not have an engine, WM's aftermarket technicians opened the front cover to fill glass water and check the 12V power supply. The operation of laying anti-scratch gaskets on the front bumper and fenders is very standardized and worthy of recognition.
After arriving at the store, after communication, I learned that this W6 did not carry out free first insurance in other media reviews, so this 10,000-kilometer maintenance needs to replace the reducer gear oil, which is also the highlight of this maintenance.
The reducer, which is directly connected to the motor, is an important component in driving an electric vehicle, similar to the gearbox of an engine. Since the load of the reducer gear is above 490 MPa, it is necessary to use lubrication, heat dissipation, oxidation resistance and corrosion resistance lubricants. Judging from the accessories provided by WM, the synthetic base oil used by W6 should be added with antioxidants, extreme pressure anti-wear agents and oily agents, which are sufficient to meet the standards of extending service life and increasing power efficiency.
The reducer gear oil change operation of W6 is somewhat similar to that of changing transmission oil, both of which loosen the screws in a position similar to the "oil pan", so that it can rely on gravity to flow out and recycle it environmentally. However, when adding new fluids, WM technicians need to use a special electric pump, re-inject lubricating oil into the integrated oil cartridge of the reducer, and then use a torque wrench to close the filling port.
Reducer gear oil as the most frequently replaced oil for new energy vehicles, in fact, the replacement frequency is much longer than the engine oil, such as the replacement cycle guided by the WM after-sales manual is two years and forty thousand kilometers. Considering that the cost of lubricating oil, including man-hours, is only more than two hundred yuan, its presence in the cost of the car is not strong.
Another WM suggested that every 10,000 kilometers can do self-funded projects, is to replace the air conditioning filter, the cost is more than a hundred yuan, and I bought accessories on the shopping platform at the same price. Originally, I once felt that the air conditioner was not turned on at any time, and it was completely possible to change it again for 20,000 kilometers, but after the Weima technician took it out, I dismissed such a thought, and with the current air condition, it is indeed not the degree to which it can be used to blow.
It is worth explaining that the replacement of the W6 air conditioning filter element needs to remove the glove box, I just saw the technician get started, but also firmly believe that this is a big project, the result before and after it took a minute or two to complete, it seems that usually really want to change the air conditioning filter, is not an impossible task.
The payment link has ended, the total cost of the two construction projects of the W6 is 425 yuan, for me who often haunts the car repair shop, this price is placed in front of most fuel vehicles, rounding is almost equal to no money.
What's more, WM Aftermarket also offers a wealth of free checks. In addition to our familiarity with the fastening of the suspension structure, the monitoring of the braking system, and the observation of the tire hub, for the power battery of the W6, the technician not only checks the appearance of the battery pack, high-voltage wiring harness, connector, etc., but also conducts a pressurization test with professional equipment on the insulation of the power battery, completely blocking the possible safety hazards.
After spending a few minutes upgrading the new ESC Safety Assist system, WM's service specialist drove the W6 to wash the car. At this time, the EX5 sent by the driver entered the maintenance station and began to complete the maintenance of 60,000 kilometers.
Although for fuel vehicles, 60,000 kilometers already need to check and replace a lot of accessories and oil, but our EX5 does not have the psychological burden of returning to the furnace, and the maintenance project only has more coolant replacement than W6, which is also something that needs to be completed every 60,000 kilometers. The whole replacement process, in fact, is similar to the fuel vehicle, that is, gravity emptys the original coolant, and then directly injects it into the standard line at the injection port of the front cabin - from the pink color point of view, Weima's coolant is not special, but its role in addition to covering the motor, motor controller, DC / DC heat dissipation, but also need to the battery pack in different working conditions for heat dissipation and heating, so from a safety point of view, its cooling system is not only high sealing requirements, but also needs to be anti-corrosion non-electrolytic liquid. Considering that WM gives a fairly reasonable after-sales price, I think the owner does not need to operate it himself to avoid causing unnecessary trouble.
Finally, WM after-sales technicians also read the data of the battery pack through the software, from the equipment display, after driving 60,000 kilometers EX5 not only did not have significant attenuation, the voltage between each battery module is also very stable, it can be seen that WM's three-electric system is very well controlled.
What makes me feel more intimate is that WM can not only query the time, mileage and project of each maintenance from the car machine and app, but also even display the maintenance cost, which is a transparency that most brands do not provide. Judging from the relevant records, the maintenance of this EX5 is quite irregular, counting today,It has only done four maintenance, but the service commissioner said that this does not affect the warranty of the whole vehicle. In the end, the total cost of the EX5 after a total of 60,000 kilometers was less than 1,500 yuan, which also included a fragrance kit that cost 225.5 changes. More importantly, the maintenance cost of EX5 can be used as a reference for W6, although the price and positioning of the two models are completely different, but the accessories and working hours given by WM are exactly the same.
As a comparison, I inquired about the estimated total price of Japanese, German and American fuel SUVs of the same level as the W6 in 60,000 kilometers of maintenance, which basically cost tens of thousands of yuan. In this way, W6 can save a lot of money only in the maintenance of this piece, if you compare the energy consumption cost of driving 60,000 kilometers, the gap between the two will be widened - W6 currently shows the average electricity consumption of 100 kilometers is 17 degrees, the electricity expenditure in the case of home charging is about 5,000 yuan, and in the calculation of 8L/100km of No. 92 gasoline, the owner's fuel expenditure will reach about 34,000.
Therefore, in this conversion, the difference in the total cost of 60,000 kilometers of WM W6 and the same level of fuel SUV is close to 45,000! If the cycle of use of the car is extended, as the number of places where the fuel powertrain needs to be maintained continues to increase, the advantages of WM as an electric vehicle will be more obvious, which is enough to erase the outside world's concerns about the retention rate of new energy vehicles. In particular, WM W6 and EX5 both provide a lifetime warranty for power batteries, which is believed to make many consumers with doubts completely untie the happy knot.
Driver's Summary
I also knew that new energy models without powertrains would have lower maintenance costs, but there was no clear quantitative indicator. This time driving WM W6 to the store maintenance, not only found that the WM dealer's showroom scale, layout standards and can see the transparent workshop of the rest area, is completely not inferior to the level of the joint venture brand, but also in the degree of standardization of the after-sales maintenance process, it is absolutely reassuring to hand over the car to the hands of WM after-sales technicians.
More importantly, when I sign the bill to pay, I will gush out a little sense of superiority in my heart - in the past, in order to save money, my own car would choose a familiar auto repair factory for maintenance after the insurance was issued, and the cost could be 40% off than the official channel. But the owner of the use of WM model should not bother this, from the car company's public after-sales price list, WM parts, man-hour cost has been quite affordable, and then considering the excellent durability of W6, the actual need to complete the maintenance project is not much, so there is no burden on use.
Of course, I think maintenance costs are not the first element of consumers deciding to buy a car. If you are in an extremely cold environment for a long time, there is no convenient home pile, you need to drive often for a long time, or even like to study the engine structure, it can be a reason to choose a fuel vehicle. But I think we should not be trapped in their own situation, but only from the standpoint to evaluate the electric vehicle, at least as a new energy owner, I will admit after test driving the W6, it has certain advantages in intelligence, smoothness, economy, and the low cost of maintenance, as well as a long-term warranty commitment, is the icing on the cake of the W6.
