Launch control is a feature of the manufacturing process for the Audi A3 and Audi S4. S-Tronic DSG transmissions are available on both versions. You can only use launch control up to the torque converter’s stalling rpm if your automobile has a conventional automatic transmission.

How can I tell if I am in command of the launch?
But the flag doesn’t appear until you floor it, is my argument. And if you try it out and it doesn’t work, you are making a fool of yourself. How can I be sure it will function before simultaneously applying the brakes and the accelerator?
When you depress the gas pedal, if the engine speed stays at its maximum between 3000 and 5000 rpm, the launch control has been successfully activated. If it exceeded 3500 rpm, you would either launch it at a higher RPM or stop doing it altogether.
Launch control: Does it harm the car?
Launch control is a piece of software that enables you to accelerate your car without experiencing any drama, such as wheelspin or, worse, exploding an engine cylinder.
Anyone can accelerate off the line, especially in a manual car, by putting the clutch in, reducing the throttle until it reaches a set RPM, and then releasing it. Pretty basic, yes?
Doing so, especially after several tries, might harm various components of your car, including the clutch, drivetrain, engine, and gearbox.
How quickly can a 2017 Audi A4 travel?
You can reach 130 mph on the racetrack in the base, entry-level A4 with the 40 TFSI front-wheel drive engine. This is made possible by the 2.0L 4-cylinder engine, which generates 236 lb-ft of torque and 188 horsepower.
Launch control on the 2010 Audi S5?
An S5 has no launch control. Has anyone used their S-Tronic or DSG car’s Launch Control? It works nicely if you mean to hold the brake, apply the throttle, and release the brake. An S5 has no launch control.
Has the 2010 Audi S4 launch control?
Yes, with the transmission in sport mode and the ESC in sport mode, with the left foot brake engaged and the accelerator floored until the engine reaches 3500 RPM.
What is your maximum number of launch controls?
We on the F90 board discovered a few weeks ago that BMW only allows the ZF8 transmissions to carry out 50 launches. For those of you who are interested, this means that after 50 launches, the 0-60 times on these automobiles will probably go up by almost a full second.
In order to let you know to limit launch controls, I just wanted to offer this as a warning. My 0-60 times climbed from 2.5 to 3.0 seconds, and my 1/4 mile timings went up by 2-3 tenths as well, because I used up all of mine in the first two months of ownership.
In other words, BMW is misrepresenting the performance of their vehicles by employing this method. If you utilize it, the figures in publications won’t match what you’ll see in the actual world.
Do every car’s launch controls work?
Any modern, serious performance vehicle must now have launch control. Heck, a launch control system is even included with the latest Renault Clio RS! Supercars now dominate drag racing, consistently getting the perfect launch and leaving most manual clutch-dumpers in their wake.
Since numerous videos of Nissan GTRs throwing people’s faces into extreme contortions online made them famous, practically every supercar will now come standard with a slightly different type of launch control. How then do these systems function, and how do they achieve nearly flawless acceleration?
To begin with, a launch control system has a number of tasks to finish in order to move a car off the line as swiftly and effectively as feasible. Wheel spin and hop must be eliminated, usable power, weight transfer, and traction must all be maximized, and in forced-induction powertrains, boost must be built to the necessary level.
Launch control is typically activated by selecting a particular driving mode from the traction control settings in most vehicles. The brake must be used for a predetermined amount of time after the setting has been made before the throttle can be floored. The exhaust then emits a spine-tingling rasp as the rev counter reaches a predetermined limit. You must then release the brake, at which moment the throttle is specifically opened to permit the least amount of tire spin and the greatest possible acceleration.
The programming of the car’s ECU accounts for the majority of this performance-enhancing wizardry. The clutch is engaged by the ECU when the brake pedal is depressed, in effect acting as a trigger mechanism.
Additionally, the computer in the automobile will have a pre-set rev limitation that turns off the ignition to prevent the engine from revving higher. The experts who programmed the ECU estimated this limit by determining the highest torque output through the wheels that will result in the quickest acceleration.
The wheels would simply spin up and waste valuable fuel turning the tyres into molten rubber on the road surface if the car were simply red-lined to initiate the fastest start possible. However, powertrains producing as much torque as they do in the current generation of performance cars prevent this from happening. Therefore, the majority of rev limiters are set to between 3500 and 4500 rpm, which will automatically decrease after the torque is released to the wheels.
While all of that is taking place on the engine side of things, the transmission also plays a significant part in transforming the rage under the hood into an absurd 0-60 mph time. When it comes to launch control systems, dual-clutch transmissions are the standard because they provide smoother, quicker upshifts than single-clutch systems. When employing the proper transmission fluid, a wet dual-clutch may effectively transmit the heat produced by the torque inputs, keeping the clutches and transmission from overheating. As a result, the DCT can launch numerous missiles without any actual risk of transmission warning lights!
The DCT’s clutches are “prepped” to receive maximum torque after the brake is released, allowing the precise torque output that was set into the ECU to reach the wheels. The ABS system then kicks in, braking whichever wheel is slipping to maximize traction, especially in all-wheel drive vehicles. Instead than just floor the throttle from 0 revs and hope for the best, this computer trickery allows for a far faster launch.
Launch control is most effective on supercars that are specifically turbocharged or supercharged, despite finding their way into supercar spec sheets all around the world. Launch control systems enable a turbocharger to spool up in advance of launch by allowing the engine to achieve a rev limit at standstill, which allows for a significantly larger power output from the engine than from a standard launch. To keep the turbocharger spooled, turbocharger anti-lag, which is effectively created by minor explosions in the exhaust system directly ahead of the turbocharger, should not be confused with this.
Even if launch control is a very efficient way to start a car, it must be acknowledged that the art of manually starting a car has been completely eliminated from the driving experience. Therefore, even if your quarter-mile time may be faster and your tires may last longer, it eliminates a significant portion of the petrolhead driving that many of us will enjoy. Would you be content if your car had a launch control system? Or would it make you happy to balance the clutch drop yourself and connect the engine and transmission in unison?
What is the launch control speed?
According to Road & Track, significant powertrain damage from multiple launches wasn’t uncommon. According to Car and Driver, Nissan had to reprogramme the R35 GT-system R’s exactly because the dual-clutch transmission of the supercar would be destroyed. In some cases, careful human input could surpass computer control in performance vehicles. It was demonstrated on an SRT Viper by Car and Driver.
Launch control is now necessary to obtain the finest acceleration data, though, as of recent years. For instance, it enables the future Hummer EV to achieve a stated 0-60 mph pace of 3.0 seconds. According to MotorTrend, the electronics just react more quickly and reliably than even some of the greatest humans can.
