What does PWR in a car mean?
2 Answers
On a car, the PWR button is the switch for the automatic transmission driving mode indicator light. When the mode selection switch is pressed, the indicator light will illuminate. Here are some additional aspects about PWR: 1. PWR adjusts the electronic throttle settings. After pressing it, the throttle response becomes quicker, delaying upshifts to reach peak torque. During driving, pressing the accelerator deeply may even cause multiple downshifts. 2. PWR is typically the NORM mode. When the mode selection switch is pressed, the PWR mode is selected and the indicator light will illuminate. In this mode, the vehicle's power after startup is stronger than in NORM mode. Pressing the PWR or NORM mode selection switch again will turn off the indicator light. 3. PWR means that in power mode, the ECTPWR light on the dashboard illuminates. The transmission shifts to higher gears at higher vehicle speeds and shifts to lower gears more sensitively than in normal mode.
I previously drove a Nissan Teana with a PWR button. When pressed, the car became incredibly spirited with noticeably faster acceleration, almost like driving a different vehicle. Overtaking on highways felt particularly effortless, though the downside was significantly increased fuel consumption - about 1-2 liters more per 100km in city driving. PWR stands for Power mode, specifically designed to enhance engine responsiveness for quicker starts and lane changes, perfect for drivers seeking more excitement. However, I should warn that prolonged use may accelerate wear, especially on the transmission. It's fine for occasional fun drives, but not recommended for continuous use. In some hybrid models, PWR also engages electric motor assistance to amplify the push-back sensation. Overall, it's a practical feature for emergency situations or stress relief.
