Last year they did it with baboons, this year Hyundai let a bunch of school kids loose on a car.
A panel of 25 children aged between four and 10 to beat up a New Generation i30 Tourer over playtime. Popular activities included jumping on seats in muddy wellies), prodding buttons, opening storage compartments, repeatedly putting windows up and down, dropping crisps, squashing bananas into fabrics and spilling orange juice on the seats. Another favourite was pulling faces to their friends in the reversing camera.
Remarkably, as with the baboon treatment, the car cleaned up remarkably well.
