Steps for performing a high-speed run in an automatic transmission car: You need to place the gear in D (Drive) mode, fully depress the accelerator pedal to accelerate, and the RPM will temporarily reach the red zone, then shift gears and repeat the process. If the transmission is a manual-automatic transmission, you can utilize the D mode with 3rd or 2nd gear. For example, driving in 2nd gear up to 70 km/h can also achieve an RPM of three to four thousand. Performing a high-speed run in a car means allowing a new car to test its higher performance capabilities, with the RPM requirement not exceeding two-thirds of the design limit. For instance, if a car's engine redline is 4500 RPM, the maximum RPM during the first tank of fuel should not exceed 3000 RPM.
For automatic transmission cars driving at high speeds, as someone who loves adventurous driving, I usually start with the preparations. First, take some time to walk around the car and check: tire pressure should meet the standard to avoid the risk of a blowout, and fuel and coolant levels should be sufficient to prevent stalling midway. After getting in the car, fasten the seatbelt and adjust the seat and mirrors to a comfortable position to ensure a clear view. After starting the engine, shift to D (Drive) mode—don’t rush to stomp on the accelerator. Instead, accelerate gradually to let the car warm up, and maintain high-speed driving only after the speed stabilizes. On the highway, always pay attention to the dashboard, monitoring RPM and temperature to avoid overheating. It’s best to use the cruise control function, which automatically maintains speed and reduces fatigue. I also enjoy listening to music to pass the time while driving, but keep the volume in check to avoid distraction. The entire process emphasizes both safety and enjoyment, especially on long trips—maintain a safe distance and keep speed within the limit, avoiding sudden lane changes or hard braking. Slow down in bad weather—safety always comes first.
As a veteran driver with over 20 years of experience, it's crucial to warm up the engine for a few minutes before hitting the highway. Before driving, ensure all passengers have fastened their seat belts. After starting the car, shift to D gear and begin smoothly by gently pressing the accelerator—avoid flooring it suddenly as it can damage the engine. Gradually increase speed to highway levels, maintaining a steady pace for optimal efficiency; using cruise control on highways is very convenient, allowing you to set a speed without constantly pressing the accelerator. Always monitor road conditions and maintain a safe distance, especially in heavy traffic. During the drive, keep an eye on the dashboard to ensure oil pressure and temperature remain normal, preventing potential malfunctions. Before exiting the highway, slow down gradually—avoid sudden braking. Regular maintenance, such as oil changes and brake inspections, is essential for worry-free highway driving. These small details contribute to a safer journey, ensuring you return home safely—the ultimate priority.
