looks at things from different angles and gets different results. Just like we can't say whether Audi is better or Mercedes-Benz is better, because everyone has different perspectives and different things valued. However, when judging the quality of a car, more than 90% of people have the same idea, looking at the three major items of the car, namely the engine, gearbox and chassis.
engines and gearboxes are talked about a lot, and they also have a certain understanding of the technical strength of various car companies. They are already familiar with their performance, thermal efficiency and fuel economy. When buying a car, you will judge it by yourself based on the engine parameters and the transmission category.
But often, many people only look at these two things when buying a car, and finally skip the chassis. In fact, the chassis is the most critical and should not be ignored. Its quality will affect the vehicle's handling performance and the overall comfort of the vehicle.
chassis architecture is not a single individual. It includes four very important systems in the car, including the transmission system, the braking system, the driving system and the steering system. These are of great significance to the driving texture of the vehicle and to maintain the safety of the vehicle.
The power generated by the engine's work needs to be transmitted to the drive wheels through the transmission system, so that the vehicle can move, and the transmission system must be linked to components such as clutch, gearbox, and drive axle. If the chassis structure is loose, the transmission efficiency will be too low. Even if the car is equipped with a 3.0T V6 engine, the power generated may not be as good as the driving texture brought by a 2.0T engine with an excellent chassis structure.
For example, the driving system includes frame, axle , suspension and other structures. During the driving process, they also need to cooperate with the engine and gearbox to transmit the engine's power and drive the vehicle to drive it. When a vehicle is hit, it is also necessary to buffer the impact force on the vehicle body to ensure the stability of the vehicle. If the chassis structure is stable enough, it can pull the vehicle back even on the verge of danger. But if the chassis structure is unstable, the result will be very dangerous.
In addition, like steering systems and braking systems, they also have irreplaceable positions in the chassis, like driving systems and transmission systems. Only by cooperating with each other can these systems protect people's daily travel, so the chassis can be ranked along with the engine and the transmission as the three most important parts of the car.
When judging a car, many insiders often check the chassis first to see what kind of suspension structure the car company has equipped for the car, is it a McPherson independent suspension + rear multi-link independent suspension, or a double wishbone + five-multi-link suspension? Because different chassis structures will also bring different driving textures to the entire vehicle. Relatively speaking, the four-wheeled independent suspension structure must have a better driving texture than the non-unique suspension structure.
As the saying goes: the quality of the chassis determines the curve speed of the entire vehicle, and the engine determines the straight speed of the vehicle. Car companies that can continue to be active in the market now have certain strength in engine technology. The power output of engines with the same displacement may be only a gap of five or ten horsepower.
Take BMW 5 Series and Mercedes-Benz E-Class for example. They are both equipped with 2.0T engines. The former has a high-power engine, the maximum horsepower of , , is 252 horsepower, and the latter's high-power version has a maximum horsepower of 258 horsepower, and the power output is only 6 horsepower, which is almost negligible.
However, the chassis training methods of these two cars are completely different, and the driving experience they bring is also completely different. BMW pays more attention to the vehicle's sporty performance, so it feels more intense when driving. Mercedes-Benz pays more attention to the comfort of the vehicle, so the driving texture of the Mercedes-Benz E-Class is not as impulsive as the BMW 5 Series, but instead has a sense of elegance like a "Western gentleman".
In addition, the chassis structure will also affect the vehicle's level and positioning. Nowadays, car companies have begun to adopt platform production methods, and the main research and development target of the platform is actually the chassis design structure.With the platform, car companies can create different cars by replacing different shells on this chassis. Therefore, whether this car is an A-class car or an D-class car basically depends on what chassis is used.
Like the production platform of Volkswagen Lavida, whether it is Volkswagen itself or the sub-brand of Skoda , any model created on the same platform as Lavida is an A-class car. We can't think that this car is an B-class car, or a C-class car because its wheelbase simply does not meet the standards of B-class cars or C-class cars.
The chassis of a car is actually a field worth studying. It has a great impact on the driving texture of the vehicle and the quality of the whole vehicle. While studying engines, traditional OEMs should also pay more attention to the design and control of the chassis, so that they can occupy a more favorable position in the fierce competition in the fuel vehicle market.
