Did you know that your Q30 has achieved euro ncap 5 star safety level.
Every car is fitted with pyrotechnic detonators linked to a sensor tube behind the front bumper.
The idea being if you hit a pedestrians legs the hood (bonnet) hinges will explode shear pins alowing it to move upwards and slightly back moving the pedestrian away from hard engine components.
The sensor detects air pressure in a plastic tube rather like a straw, if the tube is squashed it will deploy the detonators, unfortunately it's that unsophisticated.
So in years to come if the front bumpers to be removed extreme caution should be applied...and disconnect the battery first.
