Is it necessary to warm up a new car before driving?

It is necessary to warm up a new car before driving. The correct method for warming up a car is to start driving 30 seconds to one minute after starting the engine, maintaining a low speed with the engine speed not exceeding 3000~3500 RPM, typically around 2000 RPM. Once the engine temperature rises to the normal operating temperature, you can resume regular driving. Additional information: Below are some precautions for warming up a car: 1. Idling to warm up the engine should not be prolonged excessively. 2. Avoid pressing the accelerator pedal aggressively while idling. It is best to drive smoothly at around 40 km/h for the first 2-4 kilometers. 3. Small-displacement engines, such as 3-cylinder or 4-cylinder engines, must be thoroughly warmed up. 4. When warming up a car in an underground parking lot, do not drive off with just a slight rise in coolant temperature.

I think modern cars don't really require prolonged idling to warm up. Because contemporary engine designs are quite advanced, utilizing electronic fuel injection technology where oil circulation and lubrication are achieved within seconds after startup - you can just drive off directly. Older vehicles needed warm-up due to slower carburetor systems, where preheating stabilized engine operation, but new cars' electronic systems automatically optimize this. Extended idling only wastes fuel and increases emissions, which is counterproductive. From my personal experience, waiting 10-30 seconds after startup for oil lubrication before driving yields optimal results, especially during cold winter conditions. There's no need to rigidly adhere to outdated habits of idling for minutes – it saves time and is more environmentally friendly.

My habit with a new car is to wait a little while after starting it before driving. In summer, I might drive off directly, but in winter or on cold mornings, I warm up the engine for a few seconds to half a minute, which makes it run smoother. The main idea is to let the lubricating oil circulate to reduce wear, but with new car engines having better materials, it's not a big issue even if you don't warm it up for a short time. If you drive off directly, keeping the speed low for the first few dozen seconds can achieve a similar effect. It's fuel-efficient and simple, no need for excessive measures. In short, just adjust flexibly based on the weather and the car's condition.

From a pollution reduction perspective, warming up a new car is unnecessary. Modern vehicles heat up quickly after starting, and idling only increases exhaust emissions and fuel consumption. Engine designs are optimized for cold starts, and prolonged idling is actually less eco-friendly. I recommend driving gently right after starting to help the engine warm up more efficiently through motion. Remember, less idling means contributing to environmental protection—simple and practical.

Briefly warming up a new car at startup is beneficial, mainly to allow the engine oil to circulate and reduce cold-start wear. The internal components of a new car's engine are precise, so a short idle of 10 to 20 seconds is sufficient, just avoid immediate acceleration or high-load driving. Not warming up isn't a big issue either, as modern cooling systems work quickly. The key is to adjust based on temperature, such as paying extra attention to oil circulation in colder regions. This helps protect the engine and extend its lifespan.
