How can powerful cars easily do a burnout, but also take off from the line without spinning their tires?
In: Engineering
Older cars did struggle with this exact issue and it was mainly down to driver skill, clutch and throttle balancing to maintain traction.
Newer cars with faster computers and faster controls can limit so many variables to certain parameters, and then monitor those parameters and change them if they detect slip on a certain tyre.
The earliest tech example is two step limiting. A control which allowed the engine to rev to a certain rpm ( an rpm where dumping the clutch wouldn’t cause a burn out, but a launch ) before the actual red line or cut off limit.
New traction control systems use mainly clutch bite (automatics). Where essentially if slip is detected then clutch pressure can be relieved. Combined with a little bit of braking pressure, and throttle adjustments.
