The new Mercedes C-class as a change, both the design concept and intelligent configuration have been upgraded, and in many aspects to refresh the market standard, can be called the S-class in the same level.
So?
The main changes in the all-new Mercedes-Benz long-wheelbase C-Class focus on the way it is driven.
The new C adopts rear-wheel drive mode, and the rear car is significantly more high-end than the front car. This time, we will talk about the powerful advantages of the new C rear car over the front car.
The whole power transmission system of the front drive car is all located in the front of the car. After the output power of the transverse engine, it is transferred to an equally compact main reducer through a very compact gearbox for deceleration and twisting, and directly drives the two front wheels.
Then drive different, longitudinal engine output power to a specific volume of gearbox box, and then through a very long drive shaft, the transmission of power to the gearbox located in the rear wheel of the main reducer output, drive the rear wheel.
Therefore, from the point of view of materials, the gearbox and the main reducer of the front drive are very small, so it does not need a high cost, so the cost is reduced.
However, the rear-drive gearbox is bulky, which costs a lot of money, and the main reducer is large, which also costs money;
Add that one drive shaft, the natural cost is higher than the previous drive.
The chassis design, that’s the key.
First of all, through the description of the front has probably known prior to drive the mechanical structure, all the heavy components concentration in front, behind the front wheel is nothing happened, so, in the car body structure, the front is very simple, need only in car welding a vice frame used for power system of a complete set of bearing and to strengthen the mechanical hardness.
The big piece in the back doesn’t need any reinforcement at all.
This can have a big impact on car prices!
The reason is that the material used to strengthen the frame is generally ultra-high strength steel, and you should know that the cost of ultra-high strength steel is not cheap, the front drive here can save a lot of money.
Not only that, the precursor has cost advantage in manufacturing, in the absence of the back of the drive shaft and the main reducer, chassis can make flat, for the bulk, such as automobile chassis manufacturing cost compared with much lower, as a result, in manufacturing, it will make a great cost advantage of precursor, of course, the cost is low, the price will be lower.
For one thing, the rear car chassis has to accommodate the whole drivetrain from front to rear. Not only the front of the car, but also the middle and rear of the car have to be strengthened. As a result, the overall chassis has to be much stronger than the FF car, for one thing.
