Q1:If the rear suspension of the new Sagitar is replaced by an independent suspension, what will happen to the semi-independent suspension of the new Sagitar we bought in 2013? Isn’t this a scam?

A1：It is difficult to upgrade current semi-independent suspension models to independent suspension. Although there are successful cases in China, car owners have spent tens of thousands of yuan. General car owners seriously do not recommend such an upgrade. The difference between independent suspension and semi-independent suspension is not very obvious, and it is not worth spending so much money on it.

In addition, this situation is not an unequal transaction or a 'trap'. It is normal for cars to have price reductions or additional configurations during the entire production cycle due to R&D and production equipment cost recovery, marketing strategies, market competition and other reasons. Cars 10 years ago had lower configurations and were more expensive than now, which does not mean that the previous car companies were 'unkind'. This is the general trend of the market, and the new Sagitar may also increase the price or reduce other configurations because of this.

Q2:Does the suspension structure of models on the same platform have to be the same?

[现在的悬架系统大多数都是通过副车架连接到底盘上，这种结构有点类似于积木]

A2：They are not necessarily exactly the same. As far as Volkswagen's PQ35 and MQB platforms are concerned, they can be equipped with torsion beam and multi-link rear suspension structures on the same platform and the same model.

In fact, the concept of "car platform" is relatively general and is mainly reflected in the research and development stage of cars. In order to facilitate differentiation, most of the parts that can be shared by different models, such as model development templates with similar chassis, body structures and production processes, are classified as a "platform". Engineers can design more models with different characteristics based on the different positioning of the car and through different component module combinations on the same platform.

Q3:Which one is more cost-effective, the Magotan 1.8T luxury model or the 2.0T premium model? The price difference is about 30,000, and there are not many useful differences in configuration. The key is that the engines are different. What is the difference between dry type and wet type? I searched a lot of reviews and there are different opinions.

[DSG从曾经大众的骄傲变成了现在大众的死穴]

A3：The premium model has 17-inch tires, additional rear window sunshades, automatic headlight shut-off, delayed headlight shut-off, rain sensor, electric heating for both rows of seats, 6 CDs, central control LCD screen and reversing image, keyless ignition system, and front and rear head airbags. But as you said, whether the configuration is worth it or not depends on your personal car-using habits. Some configurations are rarely used, so even if the price is very low, it won’t be of much significance. Therefore, it is recommended to choose a car model based on personal needs.

In terms of power, both cars can accelerate from 100 kilometers to 100 kilometers within 9 seconds, which is enough for most car owners. The difference is that the 7-speed dual-clutch equipped with the 1.8T is a dry dual-clutch. It is not soaked in the transmission oil to absorb heat for heat dissipation, but is cooled by air. When stopping and going in urban areas, the clutch is prone to overheating, and the gearbox enters the protection program. This problem still occurs in many cases in China.

Q4：Why is the Mercedes-Benz C-class BMW 3 Series so small but positioned as a mid-size car? Isn't it as tough as Nissan's Sylphy and Buick's GT? They are all in the compact class?

[宝马3系为了达到50:50的前后配重，把发动机尽量后移，但占据了一部分的车型空间]

A4：The positioning of a vehicle is not entirely determined by space or size, but also by comprehensive price, configuration level, power, body structure, etc.

In addition, the main reason why rear-wheel drive vehicles with the same wheelbase have smaller space than front-wheel drive vehicles is that the rear-wheel drive vehicle's longitudinally mounted engine and longitudinally mounted gearbox will occupy the longitudinal space of the cabin, causing the cabin to move backward. From a control point of view, a rear-wheel drive car with a too heavy front end will affect the steering characteristics and the drive wheels will easily slip. Therefore, models like BMW will try their best to maintain a 50:50 weight distribution on the front and rear axles to ensure excellent control performance.
