When the Euro NCAP consumer crash test programme was launched 20 years ago, its influence on car design and safety was less than clear.

It certainly caused disquiet among car makers, who were unused to public scrutiny on the sensitive subject of safety. For several years, no car maker dared use the Euro NCAP logo on its advertising for fear of legitimising the programme.

Crash testing has helped save 15,000 lives over the past 20 years

But since then, progress has been dramatic, as illustrated by this week’s graphic 40mph offset crash test into a deformable barrier of the hapless Rover 100 (pictured) – a test the humble hatchback was never designed to pass.

Over 20 years, Euro NCAP has tested around 630 individual models in a total of 1800 crash tests at a cost of £136 million. The effect on UK road deaths has been dramatic and the  annual toll of fatalities has halved to 1600.
