Another reason to produce new engine rather than copy the Metro is litigation for patent infringement. Even a "dead" company will have sold or delivered the intellectual property rights to others.This point has been explained (add nauseum)...The ''engine" that came the closest to what EM required was the 25 year old Geo Metro engine. The problem: The Molds?... no longer exist. The dies?...no longer exist. EM's options?...Pay for engineers to "copy" 25 year old technology, or Pay for engineers to design an engine that took the "best aspects" of the Metro engine, and make a better engine. Think "long term". This was the best choice for EM and the best choice for us.
Isn't this what EM has done?
With a new engine, that is less of a problem. (Some will sue anyway.)
