Bosch, the German company responsible for more than a few safety advancements over the years, has unveiled a new and more powerful 'ESP 9' electronic stability system.

Electronic stability control works by using the car's braking system to catch slides brought on by sudden or poor manoeuvring, or through adverse road conditions.

The Bosch system uses pistons to build up braking pressure, alternately braking the appropriate wheels to bring the car back on to the straight and narrow.

Current versions of the technology make a noticeable sound and pedal-feel as the system works, pumping or pulsing under foot - similar to early ABS systems.

Bosch's new 'ESP 9' system features six pistons, rather than the older version's two.

Six pistons means that the braking pressure can be built up more quickly and evenly, almost eliminating feedback and the sometimes noisy or lurching effect of ESP activation.

The six-piston system also means that full braking pressure can be applied almost instantly and, in the case of features like adaptive cruise control and torque vectoring, more delicately.

ESP 9 is also lighter than the continuing - but cheaper - Bosch ESP system, a move it says helps support manufacturer's need to save weight.

Bosch says the key to the new system is that the software is modular, allowing ESP 9 to more easily 'talk' to other software safety systems.

For now, Bosch's ESP 9 won't be cheap, making it a strictly prestige-focused option. But, as with all of these technologies, it won't be long before it starts trickling down to cheaper cars and as more countries adopt mandatory ESP.
