I understand what you are saying and they are valid points.Zeitgeist said:The idea of using the same engine is as many cars as possible is a good idea. It allows the manufacturer to produce them in greater quantity which brings down cost for them and consumers. It also brings more people into using and modifying them so there can be more aftermarket and OE performance parts. Also the more people with the same engine the more likely all the problems can be found and fixes put in place to correct them without finding out the hard way. Usually the manufacturer that uses an engine so widely will also spend more money and development time to build the engine right ( even if it cost a little more ) if it plans on staking so much in one or two engines.
