From oil trucks to trams, although the track is different, the core technology reserves of enterprises are different, resulting in the stratification of products is still obvious.
There are many points we consider in the oil car era, the engine gearbox matches the degree of advantages and disadvantages, the chassis adjustment is good or bad, the fuel consumption performance, the sound insulation performance, so in the traditional era, many companies can not build boutique cars, there are too many considerations.
Although new energy vehicles can abandon the engine, gearbox, and can better do a good job of sound insulation, as a "car", there are still three, six, nine and so on.
One is the control, a good electric car still has the characteristics of strong control, the other is the core driving ability is strong, the charging system is not fast, the power consumption is not big, the acceleration is not fast.
A whole new set of assessment criteria is out.
Many fuel vehicles in the past have not done a good job of fuel consumption performance, many companies in the past have been spit to death because of high fuel consumption, the same medium-sized SUV, your family's fuel consumption of 15L hundred kilometers, other people's cars accelerate faster and fuel consumption can also do 10L hundred kilometers.
For example, Nazhijie Big 7 and Tiguan L are the gap between the technical reserves and the products, which is very large.
The same is true for electric vehicles, good electric vehicles can do a good job in terms of motors, electronic controls, batteries, cost, performance, control, and power consumption can be done well enough in all aspects.
For example, the current mainstream models seem to me to be Tesla and BYD.
Taking ModelY as an example, a medium-sized SUV with a weight of two tons can control the power consumption of 100 kilometers to about 12 degrees of electricity (theoretical results) in the case of ensuring a 5-second acceleration performance, in fact, in daily use, the power consumption of 100 kilometers is about 14 degrees.
Talk about the domestic first echelon player BYD Tang.
The Tang EV with a self-weight of 2.3 tons, the 565km endurance version accelerates the performance of 8.9 seconds, equipped with an 86.4kWh battery pack, analyzes the power consumption of 100 kilometers of about 15.3 degrees, BYD Tang EV because of the larger size, greater wind resistance, and greater weight, the theoretical performance of 15.3 degrees 100 kilometers of power consumption is actually very good.
After all, it is only about 25% higher in power consumption than Model Y. At this time, the gap between the first echelon players can already be seen, Tesla is undoubtedly the strongest of the strong, and BYD is the strongest.
There is also a greater gap in contrast.
The size of the Model Y is the same, the zero-run C11 with little difference in self-weight, accelerates 1 second slower than the Model Y, consumes 15.3 degrees of power per 100 kilometers (theoretical data), and such data is a level of Tang EV with a larger size and greater self-weight.
Models manufactured by different enterprises have obvious mechanical literacy gaps because of different technical reserves.
In my opinion, the power consumption of 100 kilometers is the same as the fuel consumption of that year, and the strong enterprises can make the fuel consumption very low, relying on the process, technical reserves, matching ability and research and development strength.
Motors with higher integration, electronic control systems with clearer logic, and battery packs with higher energy density and lighter quality are all essential elements for low power consumption, and solving these problems requires enterprises to do their own core research and development.
The reason why Tesla has lower power consumption is because the motor is smaller and faster and the design is more reasonable, and the battery control system strategy is stronger and the distribution ability is better, and BYD is the same, fighting for the core technology.
Zero running, Weima including many new forces the reason for high power consumption, is because the core technology reserve capacity is not strong enough, the same is an electric vehicle, your motor, battery, electronic control are bought, others are their own research and development, tuning out, are an electric vehicle, but the strength of parts is a lot different.
For example, in the era of fuel vehicles, you use the engine that Mitsubishi eliminated, and Volkswagen uses the new EA211, and the fuel consumption, power, noise and reliability are definitely not the same.
Or that view, whether it is a fuel car or an electric vehicle, the fight is still a technical reserve ability and innovation ability, others build cars all rely on research and development, you build cars all by buying, over time, the gap will naturally come out.
