What is the Method for Launch Control in Cars?

Utilize the transmission to adjust the engine speed to the output platform of maximum torque, thereby enabling the engine to deliver maximum torque output at the very start, achieving optimal acceleration. Below is a detailed introduction about launch control in cars: 1. Overview: As a racing technique, launch control is recommended to be attempted on closed roads or tracks. Using launch control on public roads with traffic is considered dangerous. The initial kinetic energy of the vehicle during launch is very high, making it impossible to brake within a short distance in case of emergencies. 2. Precautions: Launch control imposes an extremely high load on the transmission of both manual and automatic cars for a short period. It is essential to allow the transmission to cool for at least 15 minutes between two launches; otherwise, it will significantly affect the transmission's lifespan.

I usually enjoy studying vehicle performance. A manual transmission launch control requires three steps. First, fully depress the clutch and engage first gear, then use your right foot to press the accelerator and raise the engine speed to around 3000 RPM to maintain power reserve. Next, quickly lift your left foot to the half-clutch position—you'll feel the car slightly lurch forward—then immediately floor the accelerator with your right foot while fully releasing the clutch with your left. The entire motion should be seamless, completed within about a second. A crucial tip is to disable the ESP traction control system, as the electronic system will otherwise cut power. Finally, practice in an open area—avoid slamming the accelerator at first and instead focus on feeling the clutch engagement point. Also, check your tire condition; heavily worn tires won’t grip the road at all.

When doing track days, launch control is frequently used, and the key lies in vehicle setup. For automatic transmission cars, switch to sport mode, while manual transmission cars need to warm up for ten minutes first. Before launching, turn off auto start-stop and traction control. When pressing both the brake and throttle to the floor, keep an eye on the tachometer to avoid exceeding 4000 RPM. For rear-wheel-drive cars, firmly grip the steering wheel, as you'll clearly feel the rear wheels spin when releasing the brake. Front-wheel-drive cars are relatively easier to control, but be mindful of understeer. Once, I drove a car with reinforced clutch plates, and after three consecutive launches, I still smelled burning. It's recommended to install an oil temperature gauge; stop immediately if the transmission overheats. Asphalt roads are the safest choice for the venue, as gravel roads can easily lead to loss of control.

I rented a hot hatchback before to try launch control. With an automatic transmission, it's actually quite simple. Keep the left foot firmly on the brake, then stomp the accelerator to the floor with the right foot - the engine will growl as it builds up power. The moment you release the brake, you feel like you're being pressed into the seatback. Although it lasts just a few seconds, the front tire wear was surprisingly severe, with visibly shallower tread patterns. The instructor said regular family cars shouldn't be treated this way - the transmission valve body can easily get damaged, and the repair bill could cover half a year's fuel. Now car enthusiasts all recommend avoiding consecutive launches, leaving at least 5-minute intervals for cooling. The most dangerous is doing this in rainy conditions - you'll definitely spin out when the road is wet.
