The 6th Tehran International Auto Show, which opened its doors on January 27 for a five-day run, has become a dominant showcase for Chinese automotive brands. The event, featuring presentations from 40 companies across the auto sector, puts a spotlight on a wide array of China-made vehicles, such as the Chery-based Phoenix, BYD's Yuan Plus, Han, Song Plus, and Dolphin, as well as the MVM X77. While Japanese, Korean, and German models are also on display, the exhibition floor is largely occupied by Chinese manufacturers. The strong presence is further amplified by several global automakers that now use China as an assembly base for vehicles sold in Iran. Industry analysts point to a combination of international sanctions and the compelling cost-effectiveness of Chinese vehicles as the primary drivers behind this surge, which includes both direct imports and local assembly operations. Visitors to the exhibition can explore a diverse range of products, from imported and locally assembled passenger cars to electric and hybrid vehicles, heavy-duty trucks, and motorcycles. The event has served as a launchpad for over 30 newly imported models, generating significant visitor interest. Notable debuts include the Lamari Ecco, the MVM X77, the MG RX9 seven-seater crossover, the Hongqi…

In the eyes of most people, a car door is just a simple component used for entering and exiting the cabin and ventilation. However, it is far from that simple. It is a key part of the vehicle structure, the first barrier to safety, a reflection of design aesthetics, and a stage for the increasing innovation of automotive technology. A car door that combines the essence of mechanical engineering, materials science, electronic technology, and industrial design. 1、 Basic function: the core of safety, convenience, and comfort The most basic function of a car door is to provide convenient passenger access. But on this basis, it has been endowed with more core missions: Passive safety cornerstone: The car door is an important component of the vehicle's side structure. It usually has built-in anti-collision beams (made of high-strength steel or aluminum alloy) inside, which can effectively resist intrusion in side collisions and reserve crucial living space for passengers. The sturdy door hinge and locking mechanism ensure that the door will not easily pop open in the event of a collision, ensuring that passengers will not be thrown out of the car. Sealing and quietness: The car door is isolated from wind, rain,…

In the design of the front face of a car, there is a component that not only carries crucial engineering functions, but also defines the visual soul of the vehicle, which is the car grille. It has evolved from a simple functional opening to the most recognizable design symbol of the brand, a perfect combination of engineering and art. 1、 Core function: The "respiratory system" of the vehicle The fundamental function of a grille is functional. It is usually an opening on the front bumper, whose main task is to introduce cooling air into the engine compartment. Heat dissipation and cooling: The engine generates a large amount of heat during operation, requiring continuous air flow through the radiator to cool it down. The grille is the entrance to this' life passage ', ensuring that the engine runs at optimal temperature. Intake demand: For turbocharged models, the intercooler also requires cold air introduced by the grille to cool the compressed high-temperature intake and improve engine efficiency. In addition, it also provides external fresh air for the air conditioning system. Protective function: The mesh or grid like structure behind the grille can effectively prevent large flying stones, tree branches, and other foreign…

The evolution of car headlights, from the initial kerosene lamps to today's intelligent laser headlights, is a microcosm of the development of automotive technology. It is not only a lighting tool for night driving, but also an important accessory for improving driving safety and vehicle appearance. From Halogen to LED: A Technological Leap Halogen headlights: With mature technology, simple structure, and low cost, they were the standard configuration for most economy cars in the past. The disadvantages are yellowish brightness, high energy consumption, and short lifespan. Xenon headlights (HID): emit light through high-voltage arc, with high brightness, white color, and long lifespan. But it requires lens and voltage regulator, which is costly and has a delay in startup. LED headlights: the current mainstream trend. It has the advantages of extremely low energy consumption, long lifespan, instant lighting, and flexible design. Not only can it achieve more intelligent brightness adjustment, but it can also shape a unique "light language", greatly improving vehicle recognition. Laser headlights: a top-level configuration of high-end brands such as Audi, which can be called the "light factory". The illumination distance is extremely long (up to twice that of LED lights), and the energy consumption is extremely low,…
