Does the 2021 Sylphy Classic new car need a break-in period?

2021 Sylphy Classic new car requires a break-in period. Precautions during the new car break-in period: 1. Generally, new cars within 5,000 kilometers are in the break-in period; 2. During the break-in period, try to avoid driving at high speeds above 90 km/h; 3. When the new car has driven about 5,000 kilometers and is about to complete the break-in period, the owner can briefly run the engine at speeds above 4,000 rpm; 4. The purpose of accelerating near the end of the break-in period is to reduce carbon deposits and improve engine performance.
I just picked up my new 2021 Nissan Sylphy Classic, and I'm quite concerned about the break-in period. Although modern engine technology has advanced with high precision, making strict break-in less necessary, I still believe it's important to drive carefully for the first 1,000 kilometers or so. Avoid frequent rapid acceleration or hard braking, and keep the RPM below 3,000 to help the piston rings and cylinders seat better, reducing early wear. The manual also suggests gentle driving for the first few hundred kilometers to ensure long-term performance stability. I’ve seen online forums mention that after break-in, the car feels smoother and more fuel-efficient. While it’s not as critical as with older cars, as a new car owner, I’d still like to put in some effort to protect it. For daily driving, just stick to normal commutes—avoid heavy loads or long highway trips—and let the car adapt gradually.
Having driven for over a decade, I find the break-in process for new cars like the 2021 Sylphy Classic isn't as complicated as it used to be. With advancements in manufacturing technology, components are well-calibrated before leaving the factory, so there's hardly any issue. Just drive gently for the first 800 kilometers or so—avoid frequently revving the engine beyond 5,000 RPM, and refrain from hard acceleration or sudden braking. Occasionally taking it on the highway can actually help by clearing carbon deposits. Mainly, refer to the user manual; Nissan might recommend gentle driving initially, but in practice, minor deviations won't have a major impact. The key is timely oil changes and maintenance, which can improve sealing and durability after the break-in period. Nowadays, we can just hit the road without being overly cautious—the car is designed for durability.
