The best-in-class models are those that have achieved the highest scores in their respective class. In 2013, a total of 33 cars were tested in seven different categories. The top achievers gained the highest overall scores, calculated from the results achieved in adult, child, pedestrian protection and safety assist tests.

The latest best in class winners include the Qoros 3 Sedan, which was the best performer of any car subjected to Euro NCAP’s crash tests in 2013 and is the first vehicle developed in China to achieve the highest five-star rating under the overall rating scheme.

Meanwhile the Renault ZOE and the Lexus IS 300h triumphed in their respective supermini/large family car categories out of all the models – both conventional and alternative fuels – in those sectors tested by Euro NCAP in 2013.

The best-in-class honour for the Small MPV category was shared by the Kia Carens and Ford Tourneo Connect.

Finally, the Jeep Cherokee and the Maserati Ghibli also took the lead in the Small Off-Road 4X4 and Executive categories respectively.

Last year saw Euro NCAP update its assessment of child occupant protection, crediting manufacturers that allow for easy installation of most popular types of child seats and which comply with the most recent revised child safety standards. In addition, the organisation has started to test voluntary-set intelligent speed assistant systems as part of the rating.

Michiel van Ratingen, Euro NCAP secretary general, said: ‘Euro NCAP is continuously evolving in response to industry innovation and consumer expectation. It is very positive that the number of four and five stars is still significant despite of the ever-increasing requirements. In 2014, another big step forward is taken by adding crash avoidance systems such as Autonomous Emergency Braking and Lane Keep Assist/Lane Departure Warning tests to the overall star rating.’

He added: ‘The decision to reward collision avoidance technologies on new cars will encourage more widespread fitment and further improve the safety of all road users in Europe. We hope that this, together with very high levels of occupant protection, will allow consumers to choose the very safest vehicles in 2014 and after.’
