Does the BMW M4 have four-wheel drive?

What does the M gear in Lavida mean?

M gear is the manual mode of an automatic transmission. In this gear, shifting can be done like in manual transmission vehicles, upshifting at high speeds and downshifting at low speeds. When using the manual shifting mode, you need to switch the gear lever to the M position. While driving, you can directly shift into the M gear. To shift gears, simply move the gear lever, use the paddle shifters on the steering wheel, or press the shift buttons. When climbing a long, steep slope, the driver can switch to manual mode and engage first gear. This restricts the vehicle to lower gears, preventing frequent gear shifts, which enhances climbing power and protects the transmission. Similarly, when descending a long slope, the driver should use manual mode to keep the transmission in lower gears, thereby controlling the speed without prolonged braking and avoiding overheating of the brakes, which could affect braking performance. Advantages of a manual-automatic transmission vehicle: Faster braking and stopping: When the vehicle is traveling at high speed and requires urgent braking, using manual downshifting can slow the vehicle down as quickly as possible. This is easier to master and operate in manual mode, allowing the vehicle to brake and stop more quickly. Faster cornering: Normally, when cornering, the driver first applies the brakes to slow down before entering the curve and then accelerates when exiting the curve. If the driver switches to manual mode before entering the curve and downshifts to use engine braking to control speed, a light press on the accelerator when exiting the curve ensures a smooth and safe exit. Faster overtaking: When overtaking, switch from D gear to manual mode and perform two consecutive downshifts. This increases the engine speed and torque, allowing the vehicle to overtake easily and quickly with just a light press on the accelerator.

What is the function of the ECON button in a car?

ECON stands for the car's energy-saving mode switch, which can be used to turn the energy-saving mode on or off. Modern cars generally offer three driving modes to choose from: energy-saving mode, comfort mode, and sport mode. Below is information about these three modes: Energy-saving mode: When the car is in this mode, fuel consumption is relatively low. The throttle pedal sensitivity decreases, and the transmission shifts up more aggressively. Comfort mode: This mode can be considered a normal operating mode for the car. In this mode, the throttle pedal response is more sensitive than in energy-saving mode. Sport mode: This mode can be used during aggressive driving. When sport mode is activated, the throttle pedal response becomes very sensitive, and the transmission delays shifting. The transmission will only upshift when the engine speed reaches the redline. After switching to sport mode, the engine speed is maintained at around 3,000 RPM, providing better power response during acceleration. When the car enters ECON mode, it can achieve reduced fuel consumption and energy savings, but the car's power output will be weaker. ECON can be understood as an abbreviation for 'economy.' In most cases, it is recommended to keep ECON mode on. It should only be turned off when high torque output is needed (e.g., when climbing a hill) or when driving at very high speeds. Pressing the ECON button activates the low-carbon, eco-friendly driving mode. Subsequently, the ECU, engine, and transmission operate intelligently in the most fuel-efficient mode to execute the driver's intentions, achieving optimal fuel economy through quick upshifts and smooth acceleration. The air conditioning also operates in an energy-saving state. When the driver presses the accelerator pedal deeply, the ECON system effectively controls the opening and closing of the intake valves to ensure smooth engine operation and energy savings. Although the ECON mode is simple and effective, it may not work under certain conditions: When the vehicle speed exceeds 120 km/h, priority is given to speed, and the energy-saving mode automatically deactivates. This means that if the car exceeds the economical speed range (usually between 60-90 km/h), the ECON mode will not save fuel. The key to the ECON mode is that it operates independently via the car's computer while driving to be effective. Therefore, it does not work during idle parking or when the car is in N, P, or manual mode. When overcoming significant resistance or requiring high torque output (e.g., when climbing a hill), the ECU prioritizes ensuring sufficient power to drive the car, and the ECON mode will not function in such cases.

How many horsepower is 115kw?

When the engine power is 115kw, it is 156.4 horsepower. 1kw=1.36 horsepower, so 115kw=1.36X115=156.4 horsepower. 115kw is the power, which is an indicator of the engine's dynamic characteristics, usually the rated power of the engine, while the net power will be slightly lower. 1 horsepower=735 watts; 1000 watts=1000 divided by 735 horsepower=1.36 horsepower. 1 horsepower equals the work of 75 kilogram-force multiplied by meters completed in 1 second, also equal to 0.735 kilowatts, or metric horsepower. 1 imperial horsepower equals 550 foot-pounds per second, equal to 76 kilogram-force meters per second, or 0.746 kilowatts. In China's legal measurement units, the unit of power is the watt. Power: Power refers to the amount of work done by an object per unit time, that is, power is a physical quantity that describes how fast work is done. Horsepower: Horsepower is a unit for measuring the performance of a car engine, and it is also an important parameter for measuring the performance of a car. Simply put, the greater the horsepower, the more energy the engine can release in the same amount of time. Power and horsepower both refer to the force generated by the engine, just in different units, both measuring how much energy an engine can produce. The following is a detailed explanation: The higher the power of the engine, the stronger its performance, but the higher the fuel consumption. Power is related to speed and torque. The higher the speed of the engine, the higher the power, and the greater the torque of the engine, the higher the power. An engine with higher speed does more work per unit time, and an engine with greater torque can output a larger moment per work cycle. To increase the power of the engine, simply increase the speed and torque. Horsepower, power, and torque are all important and indispensable. Power is horsepower, and horsepower is power, but they are different units that can be converted into each other. Normally, power is expressed in KW, horsepower in PS, and torque in N·m. When people say how many horsepower a car has, they are actually talking about how much power the car has. The greater the power of the car, the greater the horsepower, and the faster the speed. Torque is the force of the engine, which can be simply understood as: the amount of force the engine can generate in one rotation. The maximum torque represents the maximum force the engine can generate. The greater the force, the faster the acceleration and the easier it is to climb hills. In addition, another important indicator of a car is torque, which represents how much force the engine has, thereby determining the force with which the wheels drive the vehicle. Power determines how fast a car can go, while torque determines how quickly a car can accelerate. If a car is compared to a person running, horsepower (power) represents the person's top speed, and torque represents the person's explosive force. For the exact same car, the faster you want to go, the more energy you need, so power determines the total energy an engine can output. In most cases, it can be understood that the maximum power determines the car's top speed.

What is Manual-Shift Automatic Transmission?

Manual-shift automatic transmission combines manual gear shifting with automatic gear shifting in a vehicle. Essentially, it is still a type of automatic transmission that simulates the operation of a manual transmission through an electronic control system. This setup is added to automatic transmissions to enhance fuel efficiency and driving control, allowing drivers to regain the decision-making power over gear shift timing that was originally handled by the computer. Automatic transmissions can reduce the impact of manual shifting on the vehicle's drivetrain, thereby extending the vehicle's lifespan and improving ride comfort. Manual transmissions, lacking the hydraulic torque converter found in automatic transmissions, are generally more fuel-efficient.
