The ECT mode in a car is a rapid acceleration mode, similar to a sports racing mode. It can quickly increase the engine's RPM, but fuel consumption will significantly increase. It is mostly used for highway driving. When activated, the throttle feels more responsive and direct, and the gear shift timing typically occurs above 4500 RPM. The usage of ECT is as follows: 1. When the ECT switch is turned on, the transmission mode switches to sport mode. In this mode, the transmission downshifts more frequently and responsively. Additionally, since the gear is limited to a lower range, the engine RPM increases accordingly, torque output rises, and the vehicle's power performance is greatly enhanced. 2. When the ECT switch is turned off, the transmission will switch back to standard mode. In this mode, the transmission's shift logic will determine the timing of gear shifts based on the actual road conditions and the driver's intentions.

Once when I was driving a friend's car, I noticed an ECT button on the center console. Out of curiosity, I pressed it and found the car suddenly became much more powerful. Later I learned that ECT is the electronic control mode in automatic transmissions, which manufacturers call Electronic Controlled Transmission. This feature is like installing a small computer for the gearbox - when you press it, the transmission immediately becomes smarter by delaying shift timing to let the engine roar more, making hill climbing and overtaking particularly thrilling. My old Toyota can't do without it on mountain roads, but don't keep it on all the time as it consumes more fuel! For normal city driving, just use the regular D gear, and only activate this mode when you really want to push the car.

In repair shops, it's common to see car owners confused about the ECT button. Essentially, it's an electronic control function for the transmission. Manufacturers designed this mode specifically to let drivers choose their driving style: the normal mode is fuel-efficient and smooth, while the ECT mode is much more aggressive. It intentionally raises the shift points, keeping the tachometer needle hovering around 3000 RPM before upshifting, delivering power much quicker. However, prolonged use isn't great for the engine, so it's recommended only for steep climbs or when in a hurry. Nowadays, newer cars come with driving mode selections, making standalone ECT buttons increasingly rare.

When I first picked up the car, the salesperson pointed to the small button under the steering wheel and called it the 'power switch.' Later, I learned it's actually called ECT. There are basically two ways to use it: for daily commuting, I leave it untouched and drive in ECO mode, cruising along slowly; on weekends when hitting the highway, a single press turns the dashboard red instantly, and the throttle response becomes noticeably quicker—about half a beat faster. Actual tests show fuel consumption increases by around 8%, but the thrill during overtaking is undeniable. Once, fully loaded and climbing a mountain road, I almost rolled backward without ECT—luckily, I remembered to press the button just in time. This feature is perfect for those who want to occasionally let loose, but using it daily might give your wife quite a scare.

Friends who have driven Japanese cars must be familiar with the ECT button, which I like to call the 'turbo boost' function! The principle is that the vehicle's computer controls the transmission logic, allowing you to experience a sporty feeling close to S mode while in D gear. A light tap on the accelerator can trigger a downshift, the engine sound becomes deeper, and the push-back sensation kicks in. However, the steering wheel doesn't become heavier, which is different from a true sport mode. The main drawback is that the transmission reacts too eagerly, making frequent starts and stops in the city more jerky in this mode. It's recommended to activate it 5 seconds before overtaking and turn it off after use.
