Page "Electronic stability control" Paragraph 31

ESC is built on top of an anti-lock brake ( ABS ) system, and all ESC-equipped vehicles are fitted with traction control.

The ESC components include a yaw rate sensor, a lateral acceleration sensor, a steering wheel sensor, and an upgraded integrated control unit.

According to National Highway Traffic Safety Administration ( NHTSA ) research, ABS in 2005 cost an estimated US $ 368 ; ESC cost a further US $ 111.

The retail price of ESC varies ; as a stand-alone option it retails for as little as $ 250 USD.

However, ESC is rarely offered as a sole option, and is generally not available for aftermarket installation.

Instead, it is frequently bundled it with other features or more expensive trims, so the cost of a package that includes ESC could be several thousand dollars.

Nonetheless, ESC is considered highly cost-effective and it might pay for itself in reduced insurance premiums.

In the US, Federal regulations will require that ESC be installed as a standard feature on all passenger cars and light trucks beginning in 2012.
