each year, the indianapolis 500 bears some vestige of its original purpose as a proving ground for automobile manufacturers, in that it once gave an advantage in engine displacement to engines based on stock production engines, as distinct from out-and-out racing engines designed from scratch. one factor in identifying production engines from racing engines was the use of pushrods, rather than the overhead camshafts used on most modern racing engines; mercedes-benz realized before the 1994 race that they could very carefully tailor a purpose-built racing engine using pushrods to meet the requirements of the indy rules and take advantage of the 'production based' loophole, but still design it to be a state of the art racing engine in all other ways, without any of the drawbacks of a real production-based engine. they entered this engine in 1994, and because of the higher boost pressure and larger displacement that the "loophole" allowed pushrod engines, dominated the race. after the race, the rules were changed in order to reduce the amount of boost pressure supplied by the turbocharger. this amount was still 13% higher than what was allowed for the ohc engines. the engine was also allowed to retain its considerable displacement advantage. the inability of the engine to produce competitive power output after this change caused it to become obsolete after just the one race. mercedes-benz knew this beforehand, deciding that the cost of engine development was worth one win at indianapolis.
