What are the disadvantages of buying a diesel car?

[JoelMarie]

Diesel cars have the following disadvantages: 1. Poor comfort: High noise and vibration levels affect driving and riding comfort, making them relatively less common in passenger vehicles. However, with continuous technological advancements, some mid-to-high-end diesel cars have achieved performance close to that of gasoline engines. Major domestic and international automakers have also introduced many diesel sedans and SUVs. 2. High fuel quality requirements: Diesel engines have high manufacturing costs, stringent fuel quality requirements, and are heavy. The fuel injection system in diesel engines is extremely precise and difficult to manufacture. Using low-quality fuel can severely shorten the lifespan of the injection system. Due to the high compression ratio of diesel engines, they require high structural strength, resulting in greater weight and larger size. 3. Poor cold-start performance: Due to factors such as diesel's low volatility and compression ignition, cold starts in winter are not as efficient as in gasoline engines. Even with preheating devices, it takes several tens of seconds of preheating before the engine can start.
