Any problems arising from development must be solved with a development perspective and innovative practice. By innovating the operation mode of "mixed ownership", Shenzhen has solved the problem of "one kilometer after Z" in the promotion of new energy public transport, and the measures to realize the pure electrification of exclusive public transport are worthy of reference for the industry. "The charging pile has a large capital investment and rapid technology update. Without the intervention of companies with technical reserves and market power, it would be difficult for enterprises to survive." As one of the top three bus companies in Shenzhen, Yu Gang, the chairman of Shenzhen Bus Group, has a deep understanding of the "charging pile problem" encountered in the promotion of pure electric bus. Yu Gang introduced that the public transport group in a city in China had invested more than 200 million yuan to build 200 charging piles, each charging pile cost about 1 million yuan, 2-3 times the market price. Z could not recover the cost at last, and because it could not keep up with the technology update, many equipment was currently idle.

Why does the new energy vehicle suddenly "break the circle" and make many consumers "turn into fans"? Compared with traditional fuel vehicles, what are the unique attractions of new energy vehicles for consumers? What are the characteristics and differences in products, marketing and services of different automobile enterprises? With these hot topics in mind, the reporter recently selected three enterprises in the high-end field of new energy vehicles, namely Tesla, Weilai and BYD New Energy stores in Beijing for experiential interviews to observe the changes of new energy vehicles in product power, price, marketing and service from the perspective of consumers. I hope to read with readers the reasons behind the unexpected growth of the new energy vehicle industry in the middle and high-end field, which is the "race track" of new energy vehicles.

Model diversification: many people find that there are more new energy vehicles running on the street today, and the models are more abundant. Is that the case? By visiting the stores of the three automobile enterprises mentioned above one by one, the reporter found that the product power of new energy vehicles has been greatly improved, and can intuitively feel the strong development momentum of the industry. In Tesla's Beijing Huamao Store, two Model 3 cars are in the middle, and Model Y and Model X of SUV models are on both sides. The three models have the same style, dynamic and fashionable appearance, and simplified interior. The center console has no other physical buttons except for the center control display. From the appearance, the products of the three new energy vehicle brands all have a prominent feature, that is, the design style is fashionable, which is obviously ahead of fuel vehicles at the same price, close to or even beyond international luxury brands. Under the new consumption feature of "beauty is justice", this alone has greatly enhanced the attractiveness of products.
