Does the new BMW 3 Series require a break-in period?

The new BMW 3 Series requires a break-in period. Here is relevant information about the BMW 3 Series: 1. Exterior: In terms of exterior design, the domestically produced new 3 Series largely retains the design style of the overseas version of the new 3 Series. The sharp LED headlights connect with the enlarged glossy black kidney grille, complemented by the front bumper air intakes and three-dimensional lines. The latest Hofmeister kink design on the C-pillar of the new 3 Series Li model removes the "small tail" feature exclusive to the current long-wheelbase version. Dimension-wise, the overall size has increased compared to the current long-wheelbase 3 Series. Compared to the overseas version, the new 3 Series long-wheelbase version has a significant 110mm increase in wheelbase. At the rear, the car features straight and sharp taillight outlines with L-shaped red light strips inside. Additionally, the M Sport package version includes black trim with color separation treatment and ventilation holes on both sides, paired with a small spoiler and a dual-exhaust layout. 2. Interior: For the interior, the new BMW 3 Series long-wheelbase version largely follows the main design of the overseas model. Examples include the new floating LCD screen, the newly designed electronic gear lever, and the M-branded three-spoke multifunction steering wheel. 3. Powertrain: Under the hood, the new BMW 3 Series long-wheelbase version is equipped with the latest B-series 2.0T engine (B48B20B), delivering the same 184 horsepower as the current 320i/Li, though the badge has been changed to 325Li. The transmission remains an 8-speed automatic gearbox. Additionally, improvements in lightweight construction, thermal energy management, and fuel efficiency optimization enhance the car's power output. Moreover, the new model maintains a perfect 50:50 weight distribution.
Oh, I just helped my friend check out his new BMW 3 Series, and the manual has detailed break-in recommendations. Modern car engines are highly precise, with many components pre-run-in at the factory, but BMW still recommends gentle driving for the first 1,500 kilometers—no high-speed runs, no full loads, and no sudden acceleration. The goal is to allow components like pistons and cylinder liners to settle in completely, avoiding early wear. While technically not mandatory, doing so can extend the engine's lifespan and performance. From my experience, neglecting the break-in period might lead to increased oil consumption or minor unusual noises. The key is to follow the official guidelines without overthinking it. Regular maintenance is more critical—check the oil level during the new car period to ensure stable oil pressure.
