What is Launch control?
An electronic system that holds engine RPM at an optimal level for the fastest possible standing start, then releases for maximum acceleration.
Launch control is an electronic system that manages engine RPM and clutch engagement (in manual transmissions) or torque delivery (in automatic transmissions) for the fastest possible standing start. Modern launch control systems hold the engine at a calibrated RPM (typically 4,000-5,000 in turbocharged cars, lower in naturally aspirated) until the brake is released, then deliver maximum torque to the wheels with optimal traction control.
The benefit varies by car and use. AWD performance cars (Nissan GT-R, Audi RS3, Lamborghini Huracan) benefit most because launch control optimizes torque distribution between front and rear axles. Turbocharged cars benefit because launch control holds RPM at the boost threshold, eliminating turbo lag at launch. Manual transmission cars benefit but with more driver involvement still required.
Launch control is increasingly common in performance cars as standard or selectable equipment. The Tesla Model S Plaid, Lamborghini Aventador, Porsche 911 Turbo, BMW M cars, and Mercedes-AMG cars all have launch control. Some manufacturers limit launch control activation count (the launch control system may only be available 1-3 times per drive cycle to protect the drivetrain from repeated abuse).

Every Mazdaspeed3 made 263 hp and 280 lb-ft from a 2.3-liter turbo four, from 2007 through 2013. Here is how Mazda kept that torque in check through the front wheels, what magazine tests clocked, and why the 2010 car wore a grin.
Range Rover posted a video on October 26 of the camouflaged GT finishing a test drive to the Nürburgring. It calls the electric GT its most aerodynamic model ever, with the lowest center of gravity of any Range Rover, and the video keeps calling it a car.
Individual throttle bodies give every cylinder its own throttle, right at the intake port. Lexus said the setup cut the LFA's response time to about half that of a single throttle. Here is how ITBs work, which factory cars used them, and what they cost.
The Audi Q9, the brand's new full-size flagship SUV, is the first production car with three-dimensionally curved digital OLED taillights. Six panels hold 512 segments on glass 0.1 millimeters thick, and the rest of the design is kept quiet so the lights carry the look.
