Renault Twingo Euro NCAPThe Renault Twingo, Toyota Aygo, Citroen C1 and Peugeot 108 have all scored four stars in the latest Euro NCAP safety tests – one star less than the expected norm for new cars.

The crash test organisation assessed both the Twingo and the Aygo, using an equivalency demonstration to apply the Aygo’s scores to its sister C1 and 108 cars.

While both crash-tested cars showed good passenger and child protection, plus decent pedestrian safety, it was the lack of standard safety assist features that let them both down and precluded a full five-star rating: both models were awarded 56% for safety assist.

Although all four cars have ESC stability control as standard, plus a seatbelt reminder system for front and rear seats, they lack any form of autonomous braking or lane-keeping systems, and only the Twingo offers an electronic speed limiter as standard.

Euro NCAP made standard ESC a prerequisite for a five-star score a while back; the quartet passes this test but there aren’t enough safety assist systems elsewhere to lift them into the five-star arena.

Other cars tested in the September 2014 Euro NCAP tests include the Citroen Berlingo and Peugeot Partner, which were awarded three stars, and the Nissan e-NV200 electric van, which also scored three stars.

The only five-star car was the Mercedes-Benz GLA compact crossover.
