Engines allow company to save $800 per unit sold

DETROIT -- A key factor in General Motors' ability to play an aggressive price game often goes unnoticed or even draws criticism - GM's heavy use of pushrod engines.
Performance buffs belittle pushrods as crude and outdated. But pushrods - expected to make up 62 percent of the 5.5 million engines GM will sell in North America this model year - save GM roughly $800 per unit against comparable overhead-cam engines, analysts say.
That enables GM to boost incentives, add standard equipment or offer a V-6 cheaper than a competitor's overhead-cam version.
Edward Koerner, vice president for powertrain engineering operations, says pushrods fill the high-volume, price-competitive segment of GM's engine lineup. Targeted at consumers who want a reliable engine but don't care about its inner workings, pushrods "give you some feature-content opportunities," Koerner says
