Drive BMW, Ride Mercedes or Drive Mercedes, Ride BMW?

The correct saying should be 'Drive BMW, Ride Mercedes.' 'Ride Mercedes' is because Mercedes has a long history of manufacturing top-tier luxury cars and has considerable expertise in enhancing the comfort of suspension systems, making the ride more comfortable. On the other hand, 'Drive BMW' is because BMW cars are known for their excellent handling. The chassis, steering system, powertrain, and even the tuning of the electronic stability program are all geared towards the ultimate goal of driving pleasure. Below is some relevant information about Mercedes: 1. Historical Background: The world's first automobile was invented by German Karl Benz, and the first car appeared in 1886. Mr. Karl Benz is the creator of the automobile and later founded a car manufacturing company, which is Mercedes. 2. Compact SLK: As the market for high-end sports cars continues to heat up, Mercedes-Benz has timely launched the SLK series, where S stands for Sports, L for Lightweight, and K is the German word Kurz, meaning Short in English. Its silver-gray body, headlights resembling bright eyes, and the radiator grille merge with the turn signals, while the short and wide wheelbase creates the unique charm of the SLK. Its exterior gives a very concise and compact visual effect, and the body lines deliberately pursue the smooth and dynamic feel of a sports car.

What Causes the Engine to Shake with a 'Tut-Tut' Sound?

There are several reasons why a car engine may shake with a 'tut-tut' sound, including engine misfire, excessively rich fuel mixture, and cold starts. Here are the detailed explanations: 1. Engine Misfire: Engine misfire mainly refers to one or more cylinders not functioning properly. Common symptoms include intermittent exhaust flow, severe shaking of the exhaust pipe, and a clear 'tut-tut' or 'thud-thud' sound from the engine. This issue is often related to faults in the ignition coil. 2. Excessively Rich Fuel Mixture: When the engine's fuel mixture is too rich, symptoms include difficulty starting the engine, poor acceleration after starting, uneven engine operation, black smoke from the exhaust pipe, a 'tut-tut' sound from the engine, sometimes accompanied by backfiring, reduced engine power, and increased fuel consumption. This is mostly related to carbon buildup and clogged filters. 3. Cold Starts: During a cold start, the engine's lubrication is less effective due to poor oil flow and higher viscosity, leading to mechanical wear noises. Additionally, the coolant temperature is low during a cold start, and the fuel mixture is richer, resulting in incomplete combustion. This can cause the engine to shake and produce a 'tut-tut' sound, which is generally considered normal.

Does Modifying the Mid-to-Rear Exhaust System Damage the Car?

It will have a certain impact on the car. Replacing the full exhaust system mainly increases the diameter of the exhaust pipe, making the exhaust smoother and allowing the car's horsepower to be more easily utilized during high-speed driving. Replacing the mid-to-rear section primarily involves changing the catalytic converter and controlling exhaust backpressure. Theoretically, the more backpressure is released, the smaller the low-end torque becomes, which may slightly reduce acceleration performance, but high-speed horsepower will be better utilized. Additionally, modifying the exhaust system is illegal. Below are relevant extended materials: 1. Illegal Modifications: Small and micro passenger cars are allowed to install front and rear anti-collision devices; cargo vehicles are permitted to add windshields, water tanks, toolboxes, spare tire racks, etc.; and enhancing interior decorations are the three permissible modifications. Any other modifications that alter the vehicle's brand, model, engine type, or change the registered appearance and technical data of the vehicle are considered illegal modifications. 2. Penalties for Illegal Modifications: If a privately modified vehicle is driven on the road, the traffic management department of the public security organ shall confiscate the vehicle, enforce its scrapping, and impose a fine ranging from 200 to 2,000 yuan on the driver, along with revoking the driver's license.

Can a car pass the annual inspection with the malfunction indicator light on?

A car cannot pass the annual inspection if the malfunction indicator light is on. The annual inspection checks whether the car meets the required standards, and if any malfunction indicator light is illuminated during the inspection, the car will fail. Annual inspection content: Check whether the engine, chassis, body, and related equipment are clean, complete, and functional, whether the paint finish is uniform and aesthetically pleasing, whether major assemblies have been replaced, and whether they match the initial inspection records. Verify whether the vehicle's braking performance, steering control, lighting, exhaust emissions, and other safety features comply with the "Technical Requirements for Safe Operation of Motor Vehicles." Check whether the vehicle has undergone modifications, alterations, or transformations, and whether the driving license, license plate, and vehicle registration records match the actual condition of the vehicle. Also, verify whether any changes have been properly approved and documented. Inspect whether the license plate, driving license, and enlarged license plate markings on the vehicle are damaged, altered, or illegible, and whether they need replacement. For large vehicles, check whether the unit name or the name of the street, township, or district where the vehicle is registered, along with the maximum seating capacity in the driver's cabin, is painted in Chinese imitation Song font on both sides of the door as required. For trucks, check whether the rear tailgate (including the rear tailgate of trailers) displays the license plate number enlarged 2–3 times as required. For privately owned or jointly operated vehicles, check whether the word "Private" is painted on both sides of the door. The markings must be clear and should not include unit codes or other patterns (special cases require approval from the vehicle management office).
