1.2-liter displacement cars can run long distances, especially on highways, but the re-acceleration capability of small-displacement engines is very weak at high speeds. Many cars use small-displacement naturally aspirated engines or small-displacement turbocharged engines, which are fuel-efficient and have low exhaust emissions. The meaning of the golden displacement can be interpreted from three aspects: Having fuel economy characteristics; good handling, power, and comfort; being able to meet various forms of consumer use: such as business, commuting, travel, etc. In other words, it can maximally meet the various needs of consumers for car use and has a reasonable price, which is the golden displacement and golden model.

I've driven quite a few small cars before, and 1.2-liter engines are perfectly fine for long-distance trips. These designs are mainly focused on fuel efficiency, especially when cruising steadily on highways. However, small displacement means weaker power, so acceleration is slower when going uphill or overtaking—just avoid stomping on the gas pedal. Before long trips, carefully check the cooling system and engine oil, and make sure the tires are at the right pressure. Maintaining a steady speed between 90 to 100 km/h is the most economical, and avoid overloading the car to prevent straining the engine. Modern engines are durable and fuel-efficient, often consuming around 5 liters per 100 km, saving a lot on long trips. Just be mindful not to crank the AC too high in summer, as it can affect performance. In short, small engines can handle long distances—safety comes down to proper maintenance and smooth driving.

I've taken my 1.2L compact car on several long-distance trips, like that 500+ km coastal drive last time - smooth sailing and fuel-efficient throughout. Before departure, I always check brake pads and tires, ensuring proper tire pressure to prevent overheating. Cruising at 90 km/h on highways feels stable; acceleration is a tad slower but manageable, just avoid overloading passengers. The AC handles fine, and nighttime lighting works without issues. A full tank goes the distance, costing mere tens to refuel - way more economical than renting a larger vehicle. For long trips, I plan routes avoiding steep grades, packing snacks and water with planned rest stops. Though modest in power, this small engine proves perfectly capable for economical long-haul driving when operated sensibly.

1.2L displacement cars are quite economical for long-distance travel, saving on fuel costs. These engines typically consume 5 to 6 liters per 100 kilometers, significantly reducing expenses for long trips. Maintenance is simple and inexpensive, with affordable part replacements. However, avoid overloading to ease engine strain, and check engine oil and air filters before departure for better performance. They might feel sluggish on mountain roads or during quick overtakes, so avoid aggressive acceleration. Overall, small engines are economical and practical, ideal for long-distance self-driving.

Driving a small-displacement car on long trips is feasible, but safety must be prioritized. Insufficient power may cause issues on slopes or during sudden overtaking, increasing the risk of rear-end collisions. I always check the brakes and cooling system beforehand, ensuring proper tire pressure to avoid blowouts. Maintain a safe distance while driving, avoid aggressive maneuvers, and cruise steadily at around 90 km/h to give the engine a break. In summer heat, avoid running the AC at full capacity to prevent overheating. Although small cars are fuel-efficient and easy to handle, don’t forget emergency tools like a spare tire. For rough roads, choosing a flatter route is safer.
