The Modular engine got its name from its design and sharing of certain parts among the engine family, starting with the 4. 6L in 1990 for the 1991 model year. The name was also derived from a manufacturing plant protocol, “Modular”, where the plant and torque specs for 3.8 chrysler v6 pdf tooling could be changed in a few hours to manufacture different versions of the engine family. In the second half of the 1980s, Petersen, now chief executive officer, sought to update Ford’s decades-old V8 architectures, challenging Ford senior engineer Jim Clarke to do for Ford’s V8s what Jack Telnack did for Ford’s vehicle design.
The objective was to develop a new V8 engine that would surpass Ford’s earlier V8s in every meaningful way, from power and efficiency to emissions performance and smoothness of operation. Clarke and his engineers studied engine designs from major European and Japanese automakers and sought to develop a V8 that was technologically advanced and power-dense, yet also dependable with no major service required before 100,000 miles of use. Perhaps the most significant aspect of the new engine’s design was the number of variations of the engine that could be made to suit different needs. In addition to the various eight-cylinder engines produced, ten-cylinder engines eventually entered production.
Six-cylinder derivatives were also explored, though never built. With the wide array of engine configurations possible within this architecture, Ford developed a new, modular tooling system for producing different engines quickly and efficiently in the same factory. Three years later, in the third quarter of 1990, the first Modular engine, a 4. In spite having a smaller displacement, the 4. 60 MPH from a stop 1.
