The block, pistons, turbos, crankshaft, valves and other internal parts of the Ford 3.5-liter F-150 EcoBoost “hero” engine are still within rigid factory specifications after enduring testing that simulated 10 years of wear or about 160,000 miles. In an unprecedented – and high-stakes – public reveal, Ford engineers disassembled the engine for the first time in front of a live audience of nearly 1,000 at the North American International Auto Show in Detroit.
“I was amazed that, first, the engine looked as good as it did, and second, Ford took the chance of opening it up in front of the public,” said Gary Heinz, coordinator of the Automotive Student Service Education Training program at Henry Ford Community College in Dearborn. “You know that in a Detroit crowd, there are a lot of auto mechanics who know a good engine from a worn out one.”
The dyno and teardown events are captured in the final episode of a web-based documentary that went live a few days ago right here. The documentary series explores the engine’s long road of crazy durability tests, including the world’s toughest desert endurance race, the SCORE Tecate Baja 1000, in Mexico. Part one of the five-part documentary is below. Enjoy.
