Q
How often should I use wax on my car?
The frequency of car waxing should be determined based on the parking environment, climatic conditions, and the performance of the car wax. It is generally recommended to wax every 2 to 4 months. If the vehicle is parked in a garage for extended periods and road conditions are favorable, the interval can be extended to once every 3 to 4 months. For vehicles parked outdoors and exposed to sun and rain, the interval should be shortened to 2 to 3 months. In rainy seasons or areas with high humidity, the interval may be further adjusted to 1 to 2 months to protect against acid rain erosion. Wax should be reapplied promptly when the car body feels rough or the wax layer noticeably diminishes after 2 to 3 washes. New cars come with a factory-applied protective wax layer, so additional waxing is unnecessary for the first six months after purchase. The type of car wax (solid or liquid) does not affect its protective properties, though application methods differ. Liquid wax is more suitable for owners seeking convenience. Waxing not only enhances paint gloss but also provides water resistance, dust protection, and reduces static electricity. It is advisable to wax in a shaded area and avoid cleaners containing sodium chloride to safeguard the car's paint and rubber components.
Q
What happens if I don't wax my car?
Long-term failure to wax a car will accelerate the aging of the paint and cause various problems. The protective film formed by car wax effectively shields against ultraviolet rays, acid rain, and dust erosion. Without this protective layer, the paint surface will fade and turn yellow due to direct sunlight, which is particularly noticeable on white cars. Acidic substances in rainwater can penetrate the paint surface, forming water marks and dark spots, while metal parts may rust as water droplets focus sunlight. Additionally, increased static electricity on an unwaxed car body attracts more dust, making it prone to fine scratches from daily friction and harder to clean. From an economic standpoint, poor paint condition directly impacts the resale value of used cars. Although waxing isn't mandatory maintenance, regular application significantly extends the paint's lifespan. It's recommended every 3-4 months, with shorter intervals during rainy or high-temperature seasons. Opting for car wax containing polyurethane or ceramic components offers longer-lasting protection, while applying care to avoid rubber and plastic parts.
Q
What happens if you never wax your car?
Long-term failure to wax a car can have multiple impacts. The paint will age faster due to lack of protection, as ultraviolet rays, acid rain and pollutants directly erode the surface, causing fading, oxidation and loss of luster, which makes the vehicle appear aged. Additionally, unwaxed paint surfaces have increased friction, making them more prone to accumulating stubborn stains and harder to clean. Minor daily scratches are also more likely to leave marks.
From a practical standpoint, the absence of a wax layer reduces the vehicle's water resistance and anti-static properties. Rainwater may create a convex lens effect that burns the paint, while metal components become more susceptible to rust. Regarding used car value, paint condition is a critical assessment factor - the dullness and minor damage resulting from prolonged non-waxing directly impact resale prices.
It's advisable to select appropriate car wax based on usage conditions, such as UV-resistant or carnauba wax. Regular vehicles require waxing every 2-3 months, while garage-kept cars can extend to 4 months. Monitor water bead formation on the surface (uniform, round beads indicate good condition) to determine when rewaxing is needed. New vehicles shouldn't be waxed for the first five months to preserve the factory protective coating. Dark and light colored paints should use corresponding wax shades for optimal visual results.
Q
What is the main purpose of the exhaust system?
The main function of an automobile exhaust system is to efficiently process and discharge the exhaust gases generated by engine combustion, while reducing noise and minimizing environmental pollution. This system consists of components such as the exhaust manifold, exhaust pipe, catalytic converter, muffler, and tailpipe working in coordination. The exhaust manifold collects exhaust gases from each cylinder and delivers them to the catalytic converter through the exhaust pipe. The converter utilizes three-way catalytic technology to transform harmful substances like carbon monoxide and nitrogen oxides into harmless carbon dioxide, water, and nitrogen. The muffler substantially reduces exhaust noise through either sound wave cancellation or sound-absorbing structures. Ultimately, the tailpipe safely channels the purified exhaust gases outside the vehicle. Exhaust system design also involves backpressure optimization to enhance engine intake efficiency; for instance, V-type engines frequently employ a dual-exhaust configuration to improve exhaust flow. Regular inspection of the exhaust pipe's sealing integrity, the catalytic converter's effectiveness, and the muffler's condition is essential for maintaining system performance, ensuring compliance with environmental standards while prolonging the vehicle's service life.
Q
Is the exhaust system important?
The automotive exhaust system is an indispensable core component of a vehicle, and its importance is mainly reflected in three aspects. First, it collects exhaust gases from each cylinder of the engine through the exhaust manifold, transports them to the three-way catalytic converter via the exhaust pipe, and converts harmful substances such as carbon monoxide into harmless gases like carbon dioxide, ensuring compliance with environmental regulations. Second, the muffler in the system reduces exhaust noise to approximately 20-30 decibels through the principle of sound wave cancellation, significantly improving driving and riding comfort. Finally, as an end device, the exhaust tailpipe needs to ensure that exhaust gases are safely discharged outside the vehicle, preventing high-temperature gas backflow from damaging the engine. It is worth noting that the design of the exhaust system also affects engine performance; for example, equal-length exhaust manifolds can optimize airflow efficiency, while the working efficiency of the catalytic converter is directly related to fuel quality, so it is recommended to use fuel that meets the RON95 or higher standard. If exhaust abnormal noise or power reduction occurs, it may be due to muffler perforation or catalytic converter blockage, and timely maintenance should be carried out to avoid more serious mechanical damage.
Q
What is in the exhaust of a car?
Automobile exhaust is primarily composed of harmless components and harmful pollutants. Among them, nitrogen accounts for approximately 71%, carbon dioxide about 14%, and water vapor around 13%, which are normal combustion byproducts. The harmful constituents include carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), sulfur dioxide (SO₂), lead-containing compounds, and particulate matter (PM2.5/PM10). Although their combined concentration constitutes merely 1%, their impact is substantial. Carbon monoxide impairs blood's oxygen-carrying capacity; nitrogen oxides irritate the respiratory system and contribute to acid rain formation; among hydrocarbons, 32 polycyclic aromatic compounds such as benzo[a]pyrene are carcinogenic; while particulate matter can adsorb heavy metals and deposit deep within the lungs. Additionally, although carbon dioxide in exhaust is non-toxic, it remains the principal contributor to the greenhouse effect. Black smoke emission indicates incomplete fuel combustion; white smoke may result from coolant entering the combustion chamber; and blue smoke signifies abnormal engine oil combustion. To mitigate exhaust pollution, regular vehicle maintenance (including inspection of the three-way catalytic converter), use of compliant fuels, and avoidance of aggressive driving behaviors like sudden acceleration are recommended. Modern vehicles compliant with Euro 6 or China 6 emission standards achieve significant pollutant reduction through optimized combustion technologies and advanced exhaust aftertreatment systems.
Q
Is the exhaust system connected to the engine?
The exhaust system of an automobile is indeed directly connected to the engine, with the connection point located at the exhaust manifold on the engine cylinder head. As the starting component of the exhaust system, the exhaust manifold is tightly connected to the engine cylinder block via a flange, responsible for collecting the exhaust gases generated after combustion in each cylinder and directing them into the exhaust pipe. This rigid connection ensures the efficient transmission of high-temperature and high-pressure exhaust gases. Meanwhile, the design of the exhaust manifold needs to balance between reducing exhaust resistance and avoiding exhaust interference between cylinders to optimize engine performance. The entire exhaust system consists of components such as the exhaust manifold, exhaust pipe, catalytic converter, muffler, and tailpipe. In particular, V-type engines employ a dual-exhaust manifold design to connect two separate exhaust systems. If the exhaust system develops leaks or becomes clogged, it may lead to problems such as decreased engine power, increased fuel consumption, or abnormal emissions. Therefore, regular inspection of the exhaust manifold gasket sealing and system integrity is crucial for maintaining vehicle performance.
Q
What happens when exhaust fails?
When the exhaust system malfunctions, the vehicle will exhibit various abnormal phenomena, including changes in exhaust color, increased noise, reduced power, and higher fuel consumption. If the exhaust is black, it is usually due to incomplete fuel combustion, which may be caused by a clogged air filter or faulty fuel injectors; blue exhaust indicates engine oil burning, commonly seen with worn piston rings or aged valve stem seals; white thick smoke may result from a damaged cylinder head gasket allowing coolant to leak into the combustion chamber. A sudden increase in exhaust noise often stems from damaged sound-absorbing materials inside the muffler or a cracked exhaust pipe, causing the airflow impact sound to be directly emitted. Reduced power occurs because retained exhaust gas impedes the intake of fresh air-fuel mixture, lowering combustion efficiency, while increased fuel consumption results from the engine compensating for power loss by increasing fuel injection. Additionally, failure of the three-way catalytic converter will trigger the malfunction indicator light, leading to diminished exhaust purification capacity and potentially affecting compliance with emission inspections. Exhaust pipe corrosion perforation or oxygen sensor failure will also exacerbate the problem—the former causing exhaust leaks and noise, while the latter leads to improper fuel metering. It is recommended that vehicle owners regularly inspect the exhaust system, use approved fuel, and perform timely repairs to prevent cascading component damage, ensuring the vehicle meets performance and environmental standards.
Q
What does a full exhaust system consist of?
A complete exhaust system mainly consists of three major parts: the exhaust manifold, the mid-pipe, and the tailpipe. The exhaust manifold is directly connected to the engine cylinder head and collects the exhaust gases from each cylinder after combustion through branched pipelines. Its key components include a three-way catalytic converter for purifying exhaust gases and an oxygen sensor for monitoring the air-fuel ratio.
The mid-pipe runs through the chassis as an exhaust gas transmission channel. It typically features a double-layer corrugated pipe design with a steel wire mesh sleeve, secured with clamps to enhance flexibility and durability. The material is predominantly SUS304 stainless steel, known for its high temperature and corrosion resistance.
The tailpipe is located near the rear bumper. Its built-in muffler reduces noise through multi-channel airflow diversion. Some high-performance models employ specially shaped mufflers like S-type and G-type to optimize exhaust efficiency.
The entire system accomplishes exhaust gas collection, purification, noise reduction, and emission through precise coordination. The corrugated pipe structure effectively absorbs vehicle vibrations, while the three-way catalytic converter transforms harmful gases into harmless substances, complying with environmental regulations.
Notably, exhaust system design must balance back pressure and exhaust efficiency. Excessively low back pressure may impair low-RPM torque output, necessitating comprehensive consideration of the vehicle's power characteristics during modifications.
Q
How much money to fix car suspension?
The maintenance cost of car suspension varies significantly depending on the vehicle model, suspension type, component quality, and service location. For standard vehicles, replacing a single suspension component typically costs between 280 to 600 Malaysian Ringgit. A complete suspension replacement at an authorized 4S dealership ranges from 1800 to 2500 Malaysian Ringgit, while independent repair shops charge approximately 900 to 1200 Malaysian Ringgit.
MacPherson strut suspensions, owing to their simpler design, incur lower maintenance costs of about 2000 to 5000 Malaysian Ringgit. In contrast, multi-link suspensions with more complex structures command higher repair fees of 3000 to 8000 Malaysian Ringgit. Premium systems like air suspensions demonstrate substantially elevated maintenance expenses: basic retrofitting starts around 20,000 Malaysian Ringgit, while professional-grade modifications may exceed 100,000 Malaysian Ringgit.
Regarding components, standard-brand shock absorbers offer economical pricing, whereas performance-oriented brands such as Bilstein may cost 1000 to 5000 Malaysian Ringgit per unit. Vehicle owners are advised to select either manufacturer-authorized or third-party service providers based on actual requirements, prioritizing component reliability to optimize the cost-performance ratio. Implementing regular maintenance can prolong suspension lifespan up to five years, and minimizing travel on rough terrain effectively reduces component degradation.

Q
What are the principles of autonomous driving?
The core principle of autonomous driving technology is based on the collaborative operation of a closed-loop system consisting of perception, decision-making, and execution. The perception layer collects real-time environmental data through sensors such as lidar, millimeter-wave radar, and cameras. Lidar generates high-precision 3D point cloud maps, millimeter-wave radar excels at monitoring object speeds in adverse weather conditions, and cameras identify traffic signs and pedestrians. Multi-sensor fusion ensures comprehensive environmental perception. The decision-making layer analyzes data using deep learning algorithms, combines high-definition maps with real-time positioning (e.g., GPS + Inertial Measurement Unit), and completes path planning and behavioral decisions (such as lane changes or emergency obstacle avoidance) within 0.1 seconds. The execution layer precisely controls the throttle, brakes, and steering wheel through technologies like electric power steering and brake-by-wire systems, where response speed and accuracy directly impact safety. Currently, most mainstream vehicle models are equipped with L2-level systems (e.g., adaptive cruise control). L3-L4 systems are being gradually deployed in specific scenarios (such as highways or campuses), while fully autonomous driving (L5 level) still faces challenges like extreme weather adaptability and algorithmic ethics. In the future, with the widespread adoption of 5G communication and AI algorithm optimization, autonomous driving will further enhance reliability, but requires simultaneous improvements in supporting regulations and infrastructure.
Q
Are autonomous cars safe?
The safety of autonomous vehicles is a complex issue that requires multi-dimensional evaluation. Currently, models equipped with L2-level intelligent driving assistance systems have made significant progress in the local market. For example, Proton e.MAS 7, with its Shield Short Blade Battery and ADAS system, has obtained a five-star certification in the ASEAN NCAP test, with its adult safety protection score nearly perfect. The all-new Proton SAGA has become the first model in ASEAN to pass the CMR motorcycle safety certification, and its functions such as AEB and LDW have undergone localized calibration, optimizing the false trigger rate for typical road conditions like irregularly shaped tunnels and mixed motorcycle traffic. However, Minister of Science, Technology and Innovation Chang Lih Kang clearly pointed out that the implementation of fully autonomous driving (L3 level and above) still faces challenges in regulations and liability attribution, making commercial operation difficult to achieve in the short term. Current technologies focus more on improving the reliability of ADAS through multi-sensor fusion and AI algorithms. For instance, Zhixing Technology has conducted tens of thousands of kilometers of actual tests to adapt to right-hand drive and local traffic habits, while the intelligent campus autonomous vehicle evaluation framework developed by UMPSA emphasizes the importance of physical testing and localized adaptation. Overall, existing autonomous driving technologies have demonstrated high safety in limited scenarios, but full-scale deployment still requires improvements in the legal framework and further technical validation. Consumers can prioritize models that have passed ASEAN NCAP certification and are equipped with mature ADAS functions.
Q
What is LiDAR in autonomous driving?
LiDAR (Light Detection and Ranging) is a core sensor in autonomous driving systems. It accurately detects the distance, shape, and speed of target objects by emitting laser beams and measuring reflected signals. The working principle is based on Time of Flight (ToF) or Frequency-Modulated Continuous Wave (FMCW) technology. By calculating the time difference between the emission and reception of laser pulses and combining it with angle information, LiDAR generates high-precision 3D point cloud data to construct a digital model of the vehicle's surrounding environment in real time. Compared to cameras and millimeter-wave radars, LiDAR offers centimeter-level ranging accuracy, strong resistance to light interference (e.g., backlight or nighttime conditions), and effective identification of low-reflectivity objects (such as black vehicles). However, its performance is significantly affected by heavy fog or rain. Currently, mainstream automotive LiDAR systems operate at 905nm or 1550nm wavelengths, with 1550nm providing superior long-range detection and weather penetration capabilities, albeit at higher cost. Technologically, mechanical rotating designs are gradually being replaced by solid-state solutions (e.g., MEMS, optical phased arrays) to enhance reliability and reduce costs. In autonomous driving applications, LiDAR performs critical functions including environmental modeling, obstacle classification, and lane-level positioning, typically integrated with cameras and millimeter-wave radars in multi-sensor fusion systems to ensure perception redundancy. Modern 128-line high-resolution LiDAR systems can now produce detailed point cloud imagery, while chip-scale technologies are driving further miniaturization and mass-market adoption.
Q
How expensive are autonomous cars?
Currently, the prices of fully autonomous vehicles vary significantly. Entry-level models such as the Changan Benben E-Star start at approximately 25,000 Malaysian Ringgit after subsidies, while high-end models like the Tesla Model X can exceed 600,000 Malaysian Ringgit. Mainstream mid-range autonomous driving models such as the WM Motor W6 are priced between 95,000 and 130,000 Malaysian Ringgit, while the NIO ET7 starts at around 225,000 Malaysian Ringgit. The price differences are primarily driven by brand premium, sensor configuration (number of LiDAR units), computing platform tier (e.g., NVIDIA Orin chipset), and software algorithm maturity. Notably, Baidu's "Apollo Go" robotaxi service is planning market entry, with per-unit costs around 130,000 Malaysian Ringgit. The shared mobility model can substantially reduce individual usage costs. With progressing localization and widespread adoption of lithium iron phosphate battery technology, L4 autonomous vehicle prices are projected to gradually decline to the 150,000 Malaysian Ringgit mainstream range during 2026-2030, though fully driverless systems will remain concentrated in premium models above 300,000 Malaysian Ringgit in the near term.
Q
What is level 5 autonomous driving technology?
Level 5 Autonomous Driving is the highest level of automotive automated driving, characterized by complete elimination of human intervention—vehicles can independently perform all driving operations under any road conditions, environments, and weather, including complex urban roads, unmarked rural sections, and extreme climate scenarios. Currently, no mass-produced passenger vehicles in the Malaysian market meet the L5 standard, but pilot applications of L4 autonomous logistics vehicles have emerged, such as the enterprise-level logistics vehicles co-developed by ALS and Zelos, which can achieve highly automated transportation in restricted areas while still requiring human supervision as redundant support. Although Tesla's FSD system provides functions like automatic lane changing on urban roads and signal recognition locally, it remains classified as L2+ level assisted driving and requires drivers to be ready to take over at any time. From a technical perspective, achieving L5 requires overcoming three major bottlenecks: first, deep integration of high-precision sensors and AI algorithms to handle Southeast Asia's dynamic traffic environment (such as mixed motorcycle traffic); second, the vehicle-grade computing platform must achieve over 1000 TOPS to meet real-time decision-making demands; third, establishing nationwide V2X vehicle-infrastructure coordination infrastructure. Brands like Xpeng Motors are positioning Malaysia as an ASEAN autonomous driving R&D hub, and their localized CKD production and AI technology deployment may provide a data foundation for future L5 implementation. Current L4 commercial vehicle pilots (such as the collaboration between 9Sight Intelligence and Pos Malaysia) have accumulated operational data for technical iteration, but the commercialization of L5 passenger vehicles still awaits regulatory refinement and clarification of insurance liability frameworks.
