Modern cars have efficient fuel injection and engine management systems that are designed to minimize the need for warm-ups. In fact, some car manufacturers even recommend against idling their vehicles for extended periods as it can waste fuel and contribute to engine wear.
That said, if you live in a particularly cold climate, you may want to briefly warm up your engine (for about 30 seconds to a minute) before driving off. This is to help the oil circulate and reach the moving parts of the engine. However, it's important to avoid idling for too long, as this can actually do more harm than good.
The best way to warm up your engine is to simply drive it gently. Avoid revving the engine high or putting it under too much load. This will help the engine reach operating temperature quickly without causing unnecessary wear and tear.
