Steps for driving an automatic transmission car at high speed: You need to put the gear in D position, fully accelerate, the engine speed will temporarily reach the red zone, then shift gears, and repeat. If the transmission is a manual-automatic transmission, you can use D position gears 3 and 2, for example, driving at 70 kilometers per hour in 2nd gear, the engine speed can also reach three to four thousand revolutions. Below is some related information about high-speed driving for cars: 1. High-speed driving for cars, also known as letting a new car try to reach its maximum performance, requires that the engine speed should not exceed two-thirds of the design limit. For example, if a car's engine red zone is 4500 revolutions, the highest engine speed for the first tank of fuel should not exceed 3000 revolutions. 2. When driving a car at high speed, it should not be sustained for a long time. If the engine speed is maintained in the red zone for a long time, it will increase wear and even cause overheating problems, and the transmission cannot withstand it either.
I've been driving automatic transmission cars on highways for many years. Before starting, it's essential to check basic vehicle conditions, such as engine oil, brake fluid, and coolant levels, ensuring there are no shortages or leaks. Also, check the tire pressure—not too low or too high, as a blowout at high speed is very dangerous. After getting in, adjust the seat and mirrors, and only start the engine when comfortable. Let the car warm up for a minute or two until the engine sound stabilizes before moving. Shift to D gear and gently press the accelerator to speed up—don't stomp on it. Smoothly accelerate to around 60-80 km/h before entering the highway. On the highway, it's best to use cruise control for ease and fuel efficiency, keeping the speed under 120 km/h and avoiding speeding. Maintain a safe following distance of at least three to four seconds, and frequently check the mirrors and blind spots. Long drives can cause fatigue, so take a 10-minute break every two hours—drink some water and stretch. In short, prioritize stability.
