Febiac's Joost Kaesemans told 'De Tijd' "The fuel consuption and the impact on the environment of this kind of vehicle differs only very slightly from standard cars, putting them within the reach of a greater number of people."
Mr Kaesemans adds that the SUVs are also popular due to their robust and adventurous image, despite them often not even being four-wheel drive.
SUVs are also popular among older drivers as they offer more space behind the wheel and as the hieght advantage makes them feel safer.
