Some cars have it by the bucketload and others need a bit of help from their owners. We are talking style of course. These photos were actually taken at a show and we found a line of Renault 5 Turbos showing the evolution of the bonnet bulge. The act of adding a huge bulge clearly hints at the possibility of a powerful engine underneath.
Bonnet buldges hint at powerful cars such as the Pontiac Trans am and the pro street class of drag racer. A bulge can be added with a fibreglass or plastic add on or the bonnet can be panel beaten to provide a bulge. Please only do this if you genuinely have a powerful engine underneath, if it sounds weedy you will look a total idiot.
