One in two cars now fitted with ESC

The Electronic Stability Control (ESC) technology will be fitted in one in two cars built in 2012 worldwide, according to Bosch, which has produced the system since 1995.

ESC is an increasingly important aspect of car safety and a car sold in the UK without it will not be able to receive a top five-star safety rating after it was added to the tests last year.

The system corrects oversteer and understeer by monitoring the steering and brakes to keep the car under control around corners.

It was designed to help cars avoid flipping over around corners – a problem usually associated with taller cars such as people carriers.

The famous ‘Elk Test’ in Sweden is an important test for all new cars. The Elk Test simulates a car swerving to avoid an Elk in the road. While this may not be a problem in the UK, it is a common occurrence in Sweden.

However, it also improves grip in smaller cars and has become an important aspect of car safety in recent times.

Bosch says over 75 million cars have been fitted with the system across the world since 1995 and despite it beginning as a system for luxury cars and people carriers, models such as the compact Kia Rio, Ford Fiesta and Vauxhall Corsa are increasingly using the system to boost safety scores.

Gerhard Steiger, the president of the Bosch Chassis Systems Control division, said: “After the seat belt, ESP is the most important safety system in cars, and has saved many lives over the past years.”
