Does the Tang DM Need to Warm Up?
3 Answers
No need to warm up the car all year round, and prolonged idling to warm up the engine is unnecessary. About the Tang DM: There is no need to warm up the car all year round, and prolonged idling to warm up the engine is unnecessary. After starting the car, it takes about twenty seconds for the engine to stabilize, at which point you can begin driving. Prolonged idling not only increases fuel consumption but also leads to more carbon deposits. The correct way to warm up: Engines with electronically controlled fuel injection systems will rev up to 1,000 or even 2,000 rpm immediately after ignition to quickly establish the lubrication system and minimize wear.
I've been driving the Tang DM for three years now, and as a hybrid enthusiast, I must say there's no need to specifically warm up the car. After starting, it usually runs on electric power, with the engine only kicking in when the battery level drops or during acceleration. Modern engines are optimized for cold-start lubrication, so idling to warm up just wastes fuel and increases emissions. It's better to drive slowly for a few minutes to let the engine warm up naturally. In winter, just wait for the engine temperature to rise before flooring the accelerator. The hybrid system manages temperature intelligently—if you often drive short distances in the city, using electric mode means you don't even need to warm up the engine. The key is to refer to the user manual, as BYD might have specific recommendations for cold climates. But for daily commutes, starting and driving right away is the most time-efficient and eco-friendly approach. Don't stick to old habits—idling damages the car and pollutes the air. Just maintain your car well, and you'll be fine.
As someone who drives the Tang DM daily for commuting, I never specifically warm up the car. After starting, the electric motor takes over, and the air conditioning can also preheat electrically to defrost the windows, with the engine rarely intervening. The convenience of a hybrid car lies in initially running on electricity, reducing cold-start wear. Only in winter when temperatures drop below minus ten degrees Celsius do I let the engine idle for half a minute after starting to warm up the interior before driving off, but this isn't for warming up the car itself. During actual driving, the system automatically preheats at low speeds, which is much more efficient than idling to warm up the car. After driving for over a year, the car runs smoothly with low fuel consumption. My suggestion is to handle it flexibly based on the weather, prioritizing safe visibility and comfortable starts, rather than rigidly adhering to outdated ideas.
