50 years have passed since the birth of SEAT 1430 from 1969 to the present day. However, its 1,438 cc engine keeps incredible similarities with one of the most advanced engines of the moment: the 1.5 TSI 150 HP. The evolution is huge, but also, they are engines that have been implemented in numerous models of different nature. In order to accept this diversity of behaviors, it requires a series of virtues that not all of them fulfill: versatility, hardness, sobriety and balance.
