"Oil to electricity" or a real pure electric traditional car company actually gave such a result? !

It's almost 1202, and you're still struggling with electric cars. Yes, as soon as the Guangzhou Auto Show ended, detectives found that traditional car companies were facing electrification, and their practice was also considered to be the Eight Immortals crossing the sea! Do you want to stick to "oil to electricity"? What can I change if I don't change trains? Can you build a pure electric platform?

Three problems and three routes, the detective came up with solutions given by three car companies. Let's see how you might buy a car in the future ~

■? BMW: Pure electric platform? What's the hurry!

Recently, BMW has once again defined its own electrification development route: in recent years, it will still focus on the compatibility of existing platforms. By the middle of this decade, around 2025, BMW will launch a new cluster architecture and make major innovations on the CLAR platform.

In other words, in BMW's view, the pure electric platform is not so urgent. At this stage, plug-in hybrid vehicles and pure electric vehicles can be derived based on the fuel platform. In recent years, plug-in hybrid power is more important than pure electricity in BMW's eyes. For example, the plug-in hybrid version of BMW 5 Series will be increased from the original 2 models to 5 models.

Maybe you will ask: No, isn't the BMW i3 a "native" pure electric vehicle? Yes, as early as 20 14, BMW introduced i3. In the eyes of detectives, BMW did not give the sales forecast of i3, but was exploring the future electric vehicle form. Its life+driver module is also a very leading automobile architecture until today.

However, the birth of i3 is not based on a pure electric platform, but more like a completely independent product, and i3 itself has a remote version. Limited by the battery technology and the extensive use of carbon fiber materials at that time, the cost, price and practicality of i3 did not match. It can only be said that the i3 was born prematurely 10 years ago, and it was an untimely model.

If i3 is the ideal of BMW's mature car in the future, then the pure electric vehicle born on the CLAR platform is BMW's response to the skinny reality.

■? Nissan: Change trains? I change the platform!

Traditional car companies need a lot of investment to completely break away from the influence of fuel vehicles and independently develop new pure electric platforms. This is really a "bet" on a future. Is there a compromise way to build a pure electric platform by using the existing platform? Yes

Take Nissan as an example to introduce Ariya to China next year. Detectives think this is an alternative to "oil and electricity"-CMF is built on the CMF platform? EV architecture.

As the name implies, the new platform only produces EV models, and Ariya made in China will be introduced next year. From the appearance and interior, it can be seen that it has completely separated from the form of fuel vehicle and has an independent design language. In addition, Ariya's front row is completely open, and there is no bulge in the center of the back row, which is a typical product of the pure level stage.

I think Nissan is a "show" because Renault Nissan's CMF platform is characterized by dividing the whole vehicle into five structural areas, namely engine compartment, cockpit, front chassis, rear chassis and electrical architecture. Among them, the electrical architecture of the full platform model is universal, and the other four areas can be freely combined, thus deriving different types of products such as MPV, SUV, car and hatchback.

From CMF to CMF? EV benefits greatly from the division of this structure. The difference between CMF platform and platforms such as EMP of PSA and MQB of Volkswagen is that the latter pays more attention to the variable range of vehicle wheelbase and the universality of parts, while CMF pays more attention to the flexibility of design and production, including variable wheelbase.

Paying attention to the flexibility of design and production is an important condition for the transformation of CMF platform to EV. The logic of dividing structural regions enables R&D departments to focus on electrification research and development in different structural regions. Finally, CMF? The EV platform can support the wheelbase changes of different models, up to 2770 mm ... Because of its strong platform adaptability, coupled with the small size and central position of the motor, CMF? EV even allows compact models to use 18 and 19 inch wheels.

Of course, Renault-Nissan-Mitsubishi is an inseparable alliance, CMF? EV not only serves Nissan, but Renault's actions in Europe are also based on CMF? EV platform synchronization. This is also why among Japanese brands, almost only Nissan has gone far on the pure stage, because Nissan has already had the blood of Europeans.

■? Volkswagen: selling cars? Believe it or not, I sell platforms!

For the modular and platform-based route, everyone should be the most familiar to the public. Unlike BMW, Volkswagen will bet that pure electric vehicles will become the most important product type in the next era, and launched a modular platform ID for MEB electric vehicles. Series is an important product created by this platform.

Volkswagen also produced "oil to electricity" models, which originated from MQB models such as Golf, LaVida and Bora. Obviously, these three EV models are transitional products from any angle, and even played a certain role in promoting the birth of the word "oil to electricity".

However, in MEB, everything has changed. Similar to the goal of MQB, MEB is also characterized by super flexible wheelbase change, and on this basis, it pursues shorter front and rear suspension, thus creating a wider and more comfortable space with a smaller body. Volkswagen even incorporated the modular concept into the design of battery packs. Its basic structure can be used for all MEB vehicles, and it can adapt to different sizes of vehicles only by increasing or decreasing the number of modules.

The cost-intensive advantage of electric vehicles is further reflected in MEB, with ID. 3 for example, after the production line is mature, ID. The manufacturing cost of 3 is 40% lower than that of pure electric golf under MQB platform!

Volkswagen is definitely betting on the future of the whole group. According to the plan, in the next five years, Volkswagen will invest 1 1 billion euros in R&D and electric vehicle production, and the total R&D cost of MEB platform will reach 7 billion euros. You know, the platform is not static, and there will be various optimizations and adjustments in the later stage. According to the public's prediction, the research and development cost of MEB platform can only be recovered after the scale of electric vehicle industry reaches 20 million in 2029.

Why did Volkswagen introduce "industrial scale" here? Because just selling cars, who can guarantee to fill in such a big investment! Volkswagen's strategy is: not only sell cars, but also sell platforms! Open your platform to other brands! It has been announced that Ford will launch electric vehicles based on Volkswagen MEB platform in 2023, with the goal of delivering 600,000 vehicles in Europe based on MEB.

Yes, in Europe, you even drive a Volkswagen with the Ford logo ... so you can see why Volkswagen emphasizes the value of MEB and the scale of the electric vehicle industry.

■? Don't say "oil to electricity" easily? no

"Oil to electricity" is an uncomfortable word to listen to. For example, in the evaluation, it is often seen that a certain model is changed from oil to electricity, and the central bulge in the rear row is still retained. This feature has even become an important basis for judging whether an electric vehicle is "changed".

"Oil to electricity" is not only limited by the internal structure, but also difficult to jump out of the design language of the fuel version. At present, most of the "oil to electricity" models are based on the fuel version, and manufacturers give new cars "masks, skirts and signs" as eye-catching embellishment measures. Pure electric platform can liberate designers and make their ideas come true, which is difficult for "oil to electricity" models.

At the same time, due to the influence of the structure of the fuel vehicle, the axle load, chassis height and suspension adjustment of the vehicle should be adjusted accordingly to ensure that the driving experience will not be too outrageous. The detective once tried a prototype of a certain brand, only changed the electricity, and made no other adjustments. It really feels like the old man who drove my father. ...

But brands like BMW and Mercedes-Benz, whose pure electric vehicles combine the driving quality of fuel vehicles, are their bottom line. IX3 gives people a sense of control, which obviously has the flavor of fuel version X3, and even has a special taste because of its low center of gravity. Therefore, we can't deny the whole category of driving experience because the "oil to electricity" model in the past was not done well.

■? Summary of Little Detective

To tell the truth, detectives are not hostile to the word "oil to electricity", so they can be judged from the actual experience of users. ? The "oil to electricity" model will still exist for a long time in the civilian and high-end markets. It is not recommended that you evaluate future products from the previous "test-oriented model". Car companies headed by Renault Nissan have explored a road of "platform evolution" and can still build remarkable pure electric vehicles. Volkswagen is really a "poker", and success or failure is at stake, and it will be laid out on a large scale early.

Suddenly remembered that sentence: Zhang Hua was admitted to Peking University; Ping Li entered a secondary technical school; I work as a shop assistant in a department store-we all have a bright future. /kloc-looking back today after 0/0 years, I wonder if the meaning will change.
