Is it necessary to drive a new car on the highway?

After the break-in period of a new car, it is recommended to drive at high speeds to improve the engine's performance. Here is some relevant information about engines: 1. An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. 2. An engine is a complete set of power output equipment, including transmission gears, the engine block, and the drive shaft. The engine block is just a part of the entire engine but is the core component. 3. The engine block forms the skeleton of the engine and serves as the installation base for various mechanisms and systems. It houses all the main components and accessories of the engine, both internally and externally, and bears various loads. Therefore, the engine block must have sufficient strength and rigidity.

As someone who frequently discusses automotive technical details, I've encountered this issue multiple times. Running a new car at high speeds is not mandatory, as modern manufacturing processes have significantly improved; engines undergo pre-break-in at the factory, eliminating the need for dedicated high-speed driving. High-speed driving may offer some minor benefits, such as clearing slight carbon deposits at high RPMs or testing the vehicle's stability at high speeds, like braking and steering response. However, this is not compulsory; instead, I highly recommend following the owner's manual guidelines—some manufacturers may advise avoiding sudden acceleration or prolonged high speeds initially to extend component lifespan. From a technical perspective, engine break-in is more about adapting to your driving habits rather than relying on specific speeds. Daily driving in urban or suburban areas can achieve the same effect; ensuring regular maintenance and safe driving is key. Don't be misled by traditional beliefs from experienced drivers—new cars' performance is already optimized, and high-speed driving is just an option, not a rigid requirement.

In my years of driving experience, taking a new car on the highway isn't really necessary. Older cars used to require highway driving during the break-in period to smooth out engine components, but with today's advanced technology, new cars come well-prepared from the factory. When I get a new car, I enjoy taking it for a spin on the highway to test its performance, such as wind noise and acceleration, but this step can easily be skipped. Normal city driving is sufficient for breaking in a new car—just drive smoothly and avoid sudden throttle inputs. Highway driving might help improve fuel efficiency or prevent early mechanical issues like carbon buildup, but it's not a guarantee. My advice is to decide based on personal circumstances: if you frequently drive long distances, an early highway test won’t hurt. Remember, the break-in period is more about getting accustomed to the car's behavior than a mechanical necessity. The real focus with a new car should be timely maintenance and proper care to avoid problems. Don’t put too much faith in this practice—I’ve seen plenty of cars that never saw highway driving during break-in and still ran smoothly for years.

I don't think new cars necessarily need to be driven on highways. As someone who focuses on daily practicality, I mainly use my new car for commuting in the city. Modern cars are essentially broken in at the factory, so highway driving isn't a mandatory procedure. While it may offer minor benefits, such as cleaning the engine at high RPMs or testing high-speed handling, it also increases fuel consumption and carbon emissions. In daily driving, smooth acceleration and braking are more important for maintaining engine longevity. I don't specifically recommend highway break-in; just follow the owner's manual—some brands may suggest gentle driving during the initial period. For safety, make sure you're familiar with your new car before considering highway driving. In short, treat the car as a tool and drive as needed—highway driving isn't a rigid requirement.
