Can a New Car Run at 100 mph? A new car can run at 100 mph. The most important thing during the break-in period is to limit the engine speed. New Car Engine Speed: During the break-in period, excessively high engine speeds increase the possibility of damaging the piston rings. Therefore, manufacturers generally recommend limiting the speed of a new car to 80~90 km/h. Within this speed range, whether it's a manual or automatic transmission car, following normal shifting requirements or automatic speed switching points, the engine speed is around 2,500 rpm, and it should not exceed 3,000 rpm. Precautions for Driving During the Break-in Period: For a car in the break-in period, it's essential to control the driving speed and avoid excessively high speeds. After driving 1,500 kilometers, you can gradually increase the engine speed and vehicle speed to the maximum allowed by the car. Additionally, avoid pressing the accelerator too hard to ensure that pistons, cylinders, and other important components increase their load in a gentle state.
