## 📍Parts All parts have a durability value, theoretically the more advanced & expensive the higher the durability, but there are also advanced parts that are easily damaged. When the durability value is zero, the vehicle cannot be used and driven because of safety factors, and the part must be replaced. Parts can be recycled and broken down into raw materials. ## 📍Raw materials 1. Tier1 common, Tier2 advanced, Tier3 rare (the following are the raw materials of the parts) ### Tires Material：Rubber Flexibility：Very soft, soft, medium, hard, very hard tires ### Engine Material: iron, aluminum alloy Transverse engine - most common today W-type engine - higher output than V-type Rotor engine - smaller, high consumption, high fuel consumption In-line engine - high stability, most cars, low maintenance V-engine - smaller size, two systems, slightly more expensive to maintain, stable acceleration Horizontal-to-horizontal - low center of gravity, increase handling, expensive maintenance, long working hours, maintenance trouble ### Brake Brake Disc - Base, Type 1.2.3 Material: Stainless steel, iron, aluminum alloy Brake calipers - single, double, and six-piston calipers. The most common is the "two-piece cast" material, followed by the "two-piece forged" material, the "one-piece cast" material, and the "one-piece forged" material, in four grades ### Suspension Shock Absorber, Linkage Material: stainless steel, aluminum alloy ### Gearbox Material: iron, aluminum alloy Parts: pressure plate, clutch plate, flywheel Type：


Manual	High maneuverability
Automatic Transmission (AT)	Performance Stability
Continuously Variable Transmission (CVT)	Smooth gear shifting, good mechanical efficiency and fuel economy, slightly higher cost and chance of problems
Mechanical Automatic Transmission (AMT)	Economical, high efficiency, low cost, simple structure, the gearshift process will produce power interruption, so that the performance of the gearshift process is not good.
Dual Clutch Transmission (DCT)	Fast response speed, power can be fully developed, while the two sets of clutch work alternately, making the shift time extremely short, more direct shifting, less power loss, is an intelligent transmission, acceleration performance and fuel cost better than the AT
