The European New Car Assessment Programme (Euro-NCAP) carries out crash tests on cars available in Europe. Of the top 10 cars tested since 1998, none is a 4x4, and only three off-roaders make it into the the top 20 (see below).
Big 4x4s are right at the bottom of the class when it comes to pedestrian safety, getting an average Euro-NCAP crash test score of just 4 out of 36, compared with 10 and 13 for large and small family cars, respectively.
In October 2005, the British Medical Journal called for health warnings on 4x4s because of the dangers they pose for pedestrians,[10] and when new test results were released in November 2005, the only car with a zero rating for pedestrian safety was a 4x4 - the Jeep Cherokee.[11]
The UK Transport Research Laboratory released its annual report of deaths on Britain's roads in March 2005, providing hard evidence that the growth in popularity of big 4x4s is causing problems for road safety - 2004 saw the highest number of road deaths in seven years, reversing a long-term decline.[1]
The TRL blames the increasing mismatch between the size of vehicles on the road for a 1% rise in people killed in accidents in 2004. Passengers in 'super minis' were 12 times more likely to be killed than people in a 4x4 when these vehicles collided. The principal factor is the extra weight of the larger car, as well as extra height, which can override the bumpers and side impact protection on the smaller vehicle.
In the USA, where big 4x4s are even more common than in Chelsea, the safety record of 4x4s is appalling:
A 4x4 is twice as likely to be involved in a fatal rollover as an ordinary car.[5]
If a pedestrian is hit by a 4x4 they are twice as likely to be killed.[6]
In a side-impact collision with a 4x4, a car driver is around 4 times more likely to be killed than if they were hit by another car.[7]
