分数是本图鉴内的相对0–100分。用于浏览，不是工程规格。
简短问答
这类交通工具要看哪些本地机构或走廊规则？
先看本地视角中的型式认定、营运许可与枢纽——不要假定一份全球清单。
Is this a buying guide?
No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.
Are the scores official?
No. The six scores are relative editorial 0–100 marks across the 48 types on this site.
Where do the photos come from?
Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.
Why metric units?
Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.
How is this different from a wiki article?
Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.
汽车的推进、结构、控制与安全在同一运行包线内耦合。先分清各系统名称与职责，便于故障模式与合规审查。
下方仪表为设计裕度、可维护性与人因的相对评分，用于同级平台比较。

系统
车身·载荷路径
就汽车而言，Stamped steel unibody carries bending and torsion through sills, A/B-pillars, and floor pan. Crash rails and crush zones manage frontal energy before the cabin ring stiffens.
推进·动力
就汽车而言，Inline or V-layout 发动机 drives a multi-speed automatic or dual-clutch gearbox. Torque converter or clutch modulates launch; final drive and half-shafts deliver torque to driven wheels.
制动·能量回收
就汽车而言，Hydraulic 制动 circuits with ABS/ESC modulators pulse calipers per wheel. Vacuum or electric boost assists pedal effort; yaw sensors trim individual corners during slides.
车载网络
就汽车而言，Instrument cluster, infotainment, and ADAS share CAN-FD and automotive Ethernet. Steering-wheel switches and touch UI route HMI commands through gateway ECUs.
乘员安全
就汽车而言，Front, side, and curtain airbags deploy from crash sensors within milliseconds. Seat belts use pretensioners and load limiters to manage occupant deceleration.
热管理
就汽车而言，Radiator, water pump, and thermostat stabilize coolant around the block and head. HVAC condenser and cabin heater core share the front heat exchanger pack.
相对量表
热点
就汽车而言，Timing chain/belt
就汽车而言，Stretch or skipped teeth desynchronize cam timing and can cause valve-piston contact on interference 发动机s.
就汽车而言，Catalytic converter
就汽车而言，Melting substrate or poisoned catalyst raises emissions and often triggers limp-mode fuel trims.
就汽车而言，Wheel bearing hub
就汽车而言，Noise and play grow before heat buildup and ABS tone-ring damage appear at high speed.
就汽车而言，Steering rack boots
就汽车而言，Torn boots admit grit that scores the rack and causes wander or fluid leaks.
就汽车而言，Subframe mounts
就汽车而言，Cracked or settled mounts change alignment and transmit driveline vibration into the cabin.
材料
就汽车而言，HSLA body steel
就汽车而言，High-strength low-alloy sheets in pillars and rails balance formability with crash energy absorption.
就汽车而言，Al-Si hypereutectic pistons
就汽车而言，Light pistons with controlled expansion reduce reciprocating mass in gasoline blocks.
就汽车而言，DOT 4 制动 fluid
就汽车而言，Glycol-ether fluid with high wet boiling point resists vapor lock under repeated hard stops.
就汽车而言，Multi-layer steel head gasket
就汽车而言，Embossed MLS seals combustion pressure while accommodating thermal growth between head and block.
