Regular vehicle maintenance is a key measure to ensure vehicle safety and extend its service life. Core items include oil and filter replacement (mineral oil every 5,000 km, semi-synthetic oil every 7,500 km, fully synthetic oil every 10,000 km), maintenance of air filters (every 10,000-20,000 km) and cabin air filters (every 10,000 km or annually), as well as brake system inspection (brake pads approximately every 40,000 km, brake fluid every 2 years or 40,000 km). Transmission fluid should be replaced according to vehicle specifications (manual transmission every 3 years/60,000 km, automatic transmission every 40,000-80,000 km), and spark plugs should be replaced periodically based on material type (conventional every 20,000-30,000 km, platinum every 60,000-80,000 km). Additionally, tires should be inspected for wear and pressure every 5 years or 60,000-80,000 km, coolant freezing point tested every 2 years or 40,000 km, and battery condition assessed every 2-3 years. For high-usage scenarios, maintenance intervals should be reduced by 20%, with regular throttle body cleaning (every 20,000-30,000 km) and belt inspections (timing belt every 60,000-100,000 km). Specific schedules should reference the owner's manual and account for driving conditions; for instance, cabin air filters require earlier replacement in dusty environments, while frequent short trips necessitate closer battery monitoring. Systematic maintenance can reduce mechanical failure risks by 50% while optimizing fuel efficiency and road safety.

The core of car maintenance lies in regular upkeep and scientific operation, with a focus on key components such as engine oil, braking system, tires, and filters. As the "blood" of the engine, mineral oil is recommended to be changed every 5,000 kilometers or 6 months, while fully synthetic oil can be extended to 10,000 kilometers or 12 months. The oil filter must be replaced simultaneously to ensure cleanliness. The braking system is directly related to safety: brake pads need to be replaced immediately when their thickness is less than 3mm; the moisture content of brake fluid should be tested every 2 years or 40,000 kilometers (replacement is mandatory if it exceeds 3%); and any abnormal brake noise detected during daily use should prompt immediate inspection and repair. For tire maintenance, check tire pressure monthly (standard value: 2.2-2.5 Bar); replace tires when tread depth falls below 1.6mm or bulges appear; and perform tire rotation every 8,000 kilometers to ensure even wear. Replace the air filter every 10,000-20,000 kilometers (shorten the interval in sandy/dusty areas). The cabin air filter should be replaced every 6 months or 10,000 kilometers to maintain air quality. Other components requiring periodic maintenance include: spark plugs (nickel alloy: 20,000 km; iridium: 60,000 km), coolant (2-5 years depending on specification), and transmission fluid (automatic: 60,000 km). Simple tasks like wiper blade replacement and windshield washer refill can be DIY, but avoid unnecessary maintenance like throttle cleaning. For new energy vehicles, pay special attention to the three-electric system (battery, motor, electronic control) and battery charge management (maintain 20%-80% capacity). Scientific maintenance practices significantly enhance driving safety and reduce long-term costs. Strictly follow the maintenance manual while adjusting schedules according to actual driving conditions.

Comprehensive car maintenance should follow the principle of "periodic and prioritized". The core is to ensure driving safety and vehicle performance through regular inspection and replacement of key components and fluids. Basic maintenance includes changing the engine oil and filter every 5,000-10,000 kilometers or 6 months, while checking tire pressure (2.3-2.5 Bar is recommended in summer, and increased by 0.2 Bar in winter), lights and fluid levels. Mid-term maintenance (10,000-20,000 kilometers) requires additional replacement of air filters and cabin air filters (shortened to 8,000 kilometers in dusty environments), as well as checking the thickness of brake pads (must be replaced if less than 3mm) and the moisture content of brake fluid (replace immediately if it exceeds 3%). Major maintenance (40,000-60,000 kilometers) covers key items such as transmission fluid (60,000 kilometers for automatic transmissions, extendable for manual transmissions), spark plugs (60,000 kilometers for iridium ones), and timing belts (inspect at 80,000-100,000 kilometers). Car owners can independently replace wiper blades, clean filters and refill windshield washer fluid (choose products with a freezing point below local winter temperatures). Avoid unnecessary over-maintenance such as engine cleaning unless required, and retain maintenance records for traceability. Tires should be inspected monthly, and replaced when tread depth reaches 1.6mm or after more than 3 repairs, while regularly removing debris from tread grooves. Coolant level, battery condition and shock absorber leaks should also be periodically checked to ensure long-term vehicle reliability.

The drive system of an automobile refers to the mechanical device that transmits engine power to the wheels, with its core function being to ensure efficient power distribution for vehicle movement. Currently, mainstream drive configurations include front-wheel drive (power transmitted only to the front wheels), rear-wheel drive (power transmitted only to the rear wheels), and four-wheel drive (power intelligently distributed to all four wheels). For instance, the Hi4 intelligent four-wheel drive plug-in hybrid system used in the WEY G9 automatically adjusts front and rear axle torque based on road conditions, delivering both 487 horsepower of robust power and a 140-kilometer pure electric range. Conventional fuel-powered vehicles like the Mercedes-AMG A35 Sedan employ a 7-speed dual-clutch transmission coupled with a 4MATIC permanent all-wheel-drive system, where the driveshaft—a critical component—utilizes high-rigidity materials to ensure stable delivery of 400 Newton-meters of torque. With the rise of electric vehicles, manufacturers such as BYD have adopted localized production to integrate the three core electric systems (battery, motor, and electronic control) with the drive unit, achieving further energy efficiency optimization. Drive shaft market data indicates that aluminum alloy and titanium alloy variants are increasingly preferred for high-performance vehicles owing to their weight-saving properties, whereas steel driveshafts remain prevalent in budget-oriented models. The selection of a drive system directly impacts handling dynamics, energy efficiency, and production costs, requiring consumers to evaluate these aspects according to their typical usage patterns.

Front-wheel drive (FWD), rear-wheel drive (RWD), and all-wheel drive (AWD) each have their own advantages and disadvantages, and the choice should be based on specific needs. FWD features a compact structure, lower cost, and better fuel economy, making it ideal for daily urban commuting—particularly due to its enhanced stability in rainy or snowy conditions. However, it offers inferior handling and may experience power deficiency when climbing hills. RWD delivers superior handling and acceleration performance, appealing to driving enthusiasts. Luxury and performance vehicles predominantly use this configuration, though it is more prone to slipping on wet surfaces and incurs higher costs. AWD automatically distributes torque to all four wheels, substantially improving traction and stability in challenging road conditions, making it well-suited for snowy northern regions or light off-road use. That said, its intricate design results in elevated purchase and maintenance expenses, along with increased fuel consumption. For budget-conscious buyers primarily driving in urban areas, FWD is a pragmatic option; those prioritizing driving dynamics on well-maintained roads may opt for RWD; while AWD proves more appropriate for frequent adverse conditions or all-weather safety requirements. Note that the drivetrain configuration alone doesn't determine a vehicle's overall quality—factors like chassis tuning and powertrain specifications must also be evaluated comprehensively.
