2010 corvette ZR1 is coming out with new launch control as an update, and apparently it will cut close to .5 of sec from 0-100.
How it works
This device combines the effort of an electronic-driven accelerator and a computer program in the car. The software drives the accelerator according to engine specifications to make the car accelerate smoothly and as fast as possible, avoiding spinning of the drive wheels, engine failure due to over-revving, and clutch and gearbox problems. This feature is only available at the start of the race, when the car is stopped in the starting grid. After the car is running at a certain speed, this computer program routine is disabled and everything is back to normal operation.
Reason for use
In high-performance racing vehicles, the driver has a very small threshold when it comes to acceleration. High power delivered by the engine to the gearbox and driven wheels cannot be easily managed even by the most experienced drivers.
Facing this issue, and with the growing development of electronics during the 1980s, led to the introduction of this type of software.
