Plastic Fantastic: Are composite engines the future?
Armed with a vast base of research and immense skill, Holtzberg retooled his operation to mold carbon composite engine blocks, with an eye toward selling them to racing teams. Holtzberg's blocks are based on the venerable 2.0-liter Duratec mill that sees duty in the Ford Focus.
Holtzberg's carbon-fiber block has the potential to save more than 20 pounds over the aluminum equivalent, but at an enormous cost. There's no definite word on pricing just yet, but it should be at least $2,500 per pound saved, which pretty well limits the technology to race teams... for now.
The technology could make huge leaps forward in weight saving and fuel economy should it ever hit the streets, but don't figure on that happening for quite a while.
