This is from the Euro NCAP site. Don't know how reliable but this is what they say.
"Euro NCAP provides motoring consumers with a realistic and independent assessment of the safety performance of some of the most popular cars sold in Europe.
Established in 1997 and now backed by five European Governments, the European Commission and motoring and consumer organisations in every EU country, Euro NCAP has rapidly become a catalyst for encouraging significant safety improvements to new car design.
We hope that when buying a new car EuroNCAP.com will help to give you the information you need to choose safety"
