When trying to build a long-lasting legacy and a loyal fanbase that will continue to buy your latest and greatest models, manufacturers need an insignia of some kind. This could come in many forms, such as a particular feature that sets a vehicle apart from its rivals or a radical form of engine. The latter can be seen around the world, in examples such as Subaru’s Boxer engines andAudi’s throaty five-cylinder. Another instance is the Volkswagen Group’s VR6, which enjoyed an extensive production run over a span of over two decades. It left VW’s sedan line-up a while ago, though, but this only means models with the powerplant are now a bit of a bargain on the used market.
