The NC 3.75 was an interim solution, as the NC MX5 faced losing its type approval status. Only NCs sold in Europe and Japan received this device. The change in regulation was well sign posted to all manfacturers, so one wonders how Mazda was caught out to make what was probably an expensive change to a model that was on the point of being dropped (the numbers of cars with this fitted is probably very low; went on sale in Q3 2012, 10-15,000 sold in Europe over a 2 year period). The conclusion would be that the ND was behind schedule. The regulation was absolute; it wasn’t a case of redesigning a bonnet to reduce liabiliry, but to meet a standard.
