Live Teardown Of F-150 Ecoboost At Detroit Auto Show

Live Teardown Of F-150 Ecoboost At Detroit Auto Show

A never before attempted “live teardown” of Ford’s F-150 EcoBoost engine was performed at this year’s North American International Auto Show. The teardown exhibited a truck engine prepared to perform optimally for many more miles (another 150,000) even after it had reached 160,000 miles of what Ford describes as “harsh dynamometer and real-world use.”

The proof was in the fact that the key internal components of the 2011 F-150 “hero” engine were found to fit into rigid factory specs during the live teardown. Engine parts such as the block, pistons, turbos, crankshaft, valves, and other internal parts of the 3.5-liter F-150 EcoBoost engine passed rigid factory specifications after enduring testing that simulated 10 years of wear or about 160,000 miles.

“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,” said Heinz, a long-time engine mechanic who watched the teardown with a group of students.

Heinz attributed Ford’s engine design, the high-quality manufacturing process, as well as what he called “precise tolerances between the moving parts” to the low wear that was found on engine components at the teardown.

The engine with 160,000 miles that was examined at the auto show performed specific tests in order to prove it’s durability. The engine hauled 55 tons of lumber, ran at full throttle for 24 straight hours towing 11,300 pounds, beat competitors’ larger V8 engines in an uphill towing competition, and completed the world’s toughest desert endurance race in Mexico—The Baja 1000.

Ford powertrain technician Chris Rahill stated that the engine he disassembled “is not even close to being near the end of its life.”

“Given the intense engineering and research and the severity of the durability tests we run that go into all Ford engines, I’m not at all surprised how good this engine looked,” said Rahill. “Everything was within manufacturing specification. Nothing was out of the norm.”

The live teardown can be viewed in a 3-part video below:

Great job, but I can't help wonder how the tranny held up after the torture tests; was it the same tranny in all the torture episodes? I have had a few fords and the tranny is the weakest link in the powertrain...
