smart cars can go on the highway. The specific details are as follows: 1. Power: The Mercedes-Benz smart is equipped with a three-cylinder engine, delivering a maximum power of 109 horsepower (80 kW) and a maximum torque of 170 Nm. The official data states a top speed of 155 km/h. Although there are no issues with going on the highway if all documents are complete, due to its lightweight and small size, it is not recommended to drive this car at high speeds on the highway as it can easily become unstable. Even if driving on the highway is unavoidable, it is advised to keep the speed below 100 km/h. 2. Body dimensions: The dimensions are 2695 mm in length, 1663 mm in width, and 1542 mm in height, with a wheelbase of only 1873 mm. It is positioned as a micro commuter car, and there is also a convertible version available for consumers. However, there have been real cases where, after going on the highway, the panoramic roof suddenly blew off, nearly hitting a small Polo behind it. This can be considered a global first and is an important reason why it is not recommended to drive a smart car on the highway.

As someone quite knowledgeable about car performance, I can confidently say that Smart cars are fully capable of highway driving. I've personally driven a friend's Smart Fortwo on the highway and found its power quite adequate. Its engine is designed to reach a maximum speed of 140 km/h, well above China's highway speed limit of 120 km/h, so daily overtaking or cruising isn't an issue. However, due to its compact size, it might experience some sway in strong wind areas, so it's advisable to slow down and stay focused. From a technical perspective, the key to highway driving is engine stability, and Smart's small-displacement turbocharged engine handles this quite well. According to my research, it has very low fuel consumption in urban mixed driving conditions, around 5 liters, but slightly higher on highways at about 6 liters, making long-distance travel feasible. If you're concerned about range, a simple fuel tank maintenance check will ensure safety. In summary, small cars are legally allowed on highways, and safety features like ABS and airbags are fully equipped, so there's no need for excessive worry.

From a safety perspective, I've always been concerned about a vehicle's performance on highways. The Smart car is absolutely fine for highway driving. Although its compact size might give the impression of being less stable, modern designs incorporate anti-rollover systems and electronic stability control to ensure driving stability. I often drive my family out on highways, and the Smart performs quite smoothly as long as the speed is kept within reasonable limits. The key is to develop good habits: wearing seat belts, regularly checking tire pressure and brake systems—these small details can significantly reduce accident risks. Additionally, strong wind zones on highways pose a potential challenge; the Smart's lightweight body might be affected, but avoiding severe weather ensures safe passage. Based on practical experience, I've discussed this issue with other Smart owners, and the general feedback is that the Smart is very agile on highways and easy to park, but it's advisable to conduct a comprehensive vehicle check before long trips. It's quite fuel-efficient, especially for city commuting, but for me, safety always comes first.

I often drive my smart car to commute, and occasionally it runs smoothly on the highway. I remember a short trip from the city to the suburbs on the highway—the smart car was easy to handle, maintaining a steady speed of up to 120 km/h without any issues. Its compact body makes it agile in turns, and lane changes on the highway are effortless. I recommend paying attention to a few things when using it: check tire wear, avoid overloading, and refrain from sudden acceleration to prevent loss of control. The smart's urban design ensures low fuel consumption, averaging around ¥0.5 per kilometer, with little change on the highway. Legally, all road-legal vehicles are permitted on highways, and the smart fully complies with standards, so there’s no need to worry. Parking is also more convenient, as you don’t have to worry about large vehicles taking up space. Overall, driving a smart on the highway is a practical choice—my personal experience confirms its reliability and efficiency.
