What is the recommended RPM during the new car break-in period?

During the initial break-in period, keep the engine RPM between 2,000 and 2,300. In the middle phase, maintain it below 2,500 RPM, and in the later stage, control it between 2,500 and 3,500 RPM. The vehicle's break-in period is essentially a gradual process - slowly conditioning and progressively increasing the car's speed allows for optimal engine performance development. Throughout this period, avoid both excessively high and excessively low engine RPMs. For manual transmissions, refrain from maintaining a single gear for extended periods. Additionally, don't overload the vehicle during break-in as this may cause engine wear, and avoid prolonged continuous operation to allow the machinery proper adjustment time.

What is the reason for brake drag?

Brake drag is caused by the absence of free travel in the brake pedal or a malfunction in the vehicle's braking system. Brake drag refers to the phenomenon where, after the driver fully releases the brake pedal, the vehicle's braking cannot be immediately or completely disengaged, and still maintains a considerable level of braking force. This condition causes the vehicle to remain in a constant state of braking, with the brake pads continuously rubbing against the brake discs, generating excessive heat. This can lead to the burning and erosion of the wheel brakes, and in severe cases, even cause the vehicle to catch fire. Additionally, it increases the vehicle's driving resistance, resulting in higher fuel consumption and slower acceleration. Therefore, immediate repair is necessary if such a phenomenon occurs.

What is the efficiency of a gasoline engine?

The efficiency of a gasoline engine is approximately between 80%-90%. Different injection methods: Generally, gasoline engines (except for direct injection engines) mix gasoline with fuel before entering the cylinder. In contrast, diesel engines directly inject diesel into the cylinder already filled with compressed air. Different ignition methods: Diesel engines ignite through compression auto-ignition, while gasoline engines require spark plugs to ignite the air-fuel mixture. Different compression ratios: Diesel engines typically have higher compression ratios than gasoline engines, resulting in higher expansion ratios and thermal efficiency, as well as lower fuel consumption compared to gasoline engines. Gasoline engines with equivalent power are lighter and cheaper than diesel engines, but their maintenance costs are higher than those of diesel engines.

Can a newly purchased car run long-distance on the highway?

A newly purchased car can run long-distance on the highway. Do not exceed 100 kilometers per hour when driving on the highway, and avoid sudden acceleration, sudden deceleration, or harsh braking and throttle application. Inspection: It is best to have the car inspected at a 4S shop before driving on the highway. Avoid full-load operation: Running a new car at full load can cause damage to the mechanical components. Road conditions: Try to choose roads with better quality to avoid excessive vibration, impact, or emergency braking, which can reduce the load on the body and powertrain. For long-distance drives exceeding 2 hours, take breaks at service areas, as prolonged continuous engine operation can accelerate wear on mechanical components.

What is the top speed of Pagani?

Pagani (including various models) has a top speed of around 370km/h. Speed: Speed is an expression of velocity, referring to the total distance an object travels in 1 hour. The unit of speed is kilometers (km) or miles per hour (mph). Speed is commonly used in the field of transportation, but it is not the standard speed unit in the International System of Units. Pagani's powertrain configuration: Pagani is equipped with a Mercedes-Benz AMG customized M158 series 6.0L twin-turbocharged V12 engine, with a maximum power output exceeding 730 horsepower and peak torque around 1000N.m. It is paired with a 7-speed sequential single-clutch transmission, achieving a top speed of 370KM.
