Audi Q5L can perform a launch start. Definition of launch start: A launch start means adjusting the engine speed to the maximum torque output platform using the transmission during startup, so that the engine starts to output maximum torque at the moment of starting, achieving optimal acceleration. A launch start is considered a traffic violation and will result in corresponding fines and deduction of driving license points. Precautions for launch start: Attempt it on closed roads or race tracks; Before performing a launch start, ensure that the engine coolant temperature, oil temperature, and transmission oil temperature reach normal levels; Allow at least 15 minutes for the transmission to cool down between two launch starts.

I've studied the driving system of the Audi Q5L, and the high-end models are indeed capable of performing launch control. Key hardware foundations include the 7-speed dual-clutch transmission and quattro all-wheel-drive system found in the 45 TFSI version. The procedure is quite straightforward: first switch to dynamic mode and engage S gear, turn off ESC, press the brake pedal fully with your left foot, floor the accelerator with your right foot to build up revs to around 3000 rpm, then release the brake abruptly to launch. However, I recommend trying this only in closed areas as it's too dangerous on public roads. During launch, the all-wheel-drive system prevents significant wheel spin, and Audi claims the 0-100 km/h acceleration can be achieved in under 6 seconds. But be aware that frequent launch control accelerates clutch wear, so it's best to let the transmission rest for a few minutes after each session.

As an Audi owner, I've tried the launch control function on the Q5L. You must choose the 45 TFSI high-power version to access this feature, as the 40 TFSI has different hardware tuning. When activated, the dual-clutch transmission enters a competitive mode, instantly delivering power to all four wheels. The quattro system immediately adjusts torque distribution if the road is slightly wet. Once during track testing after three consecutive launches, I distinctly smelled burnt clutch. While the dashboard won't directly display an overheating warning, the intermittent flashing of the stability control light serves as the alert signal. There's absolutely no need for this function in daily driving - it's purely a performance toy. If you want to play with it, wait until the engine oil temperature reaches 90 degrees for safer operation.

In repair shops, it's common to see Audis requiring major transmission overhauls due to reckless use of launch control. The Q5L's launch control essentially involves suddenly releasing power from the transmission's semi-engaged state, generating an instantaneous impact exceeding 500 Nm. At this moment, the dual-clutch module endures friction heat three times greater than during normal gear shifts. I've encountered owners who engage in launch control over ten times monthly, resulting in the need to replace the entire clutch assembly within two years. In reality, manufacturers include this feature primarily to showcase performance potential, not to encourage frequent use. Special attention must be paid to deactivating the ESC system during operation, as triggering the protection mechanism will limit engine RPM. Avoid attempting this in cold conditions as well, since transmission fluid hasn't reached optimal lubrication state.
