Ford Learns from Engine Failures
Ford’s approach to engine development is anything but ordinary. Instead of aiming solely for victory on the racetrack, the automaker sets out to push its engines to the brink of failure, using the resulting insights to build better engines for its road-going vehicles.
Breaking Things to Build Better V8s
When Ford sends its race-prepped Coyote V8 engines into the fray, its goal is not just to win trophies. It’s to break things. Extreme racing environments expose weaknesses long before a standard road car ever could. This philosophy allows Ford to identify and address potential issues, making their engines more robust for everyday drivers.
Take, for instance, the brutal track duty cycles that revealed a flaw in the engine’s camshaft chain drive system. Ford engineers swiftly refined the design and transferred those durability upgrades directly into the production 5.0-liter Coyote V8, built at the Essex Engine Plant in Windsor, Ontario.
Celebrating Failure
This approach requires a shift in mindset. “We now celebrate internal test failures,” said Charles Poon, Ford’s vice president of Vehicle Hardware and Software Engineering. “The more issues we identify during testing, the lower the chance of our customers experiencing them.”
Ford connects two distinct internal teams to make this happen: Ford Racing Engineers and pit crews who monitor real-time telemetry and physical engines during competition. This data is then used by Product Development Engineers to re-engineer vulnerable components for mass production.

Engines pushed to the limit in both lab and track tests are sent back to facilities like the Essex Engine Plant. There, mechanics meticulously tear them down to locate structural stress points. These upgrades might never have come to fruition without the harsh conditions of racing.
“Ultimately, testing is not simply about ‘finding new defects’ — it is about validating our engineering,” Poon said. “When a failure does occur, our goal is to predict exactly what will fail and when. That level of predictability is how we prove our engineering models truly align with real-world conditions.”
Today, those race-proven refinements directly benefit everyday drivers—whether they’re towing heavy equipment in an F-150, commuting in a Mustang GT, or chasing lap times in a Mustang Dark Horse.
Ford plans to put these educated observations to the ultimate test next year when the company’s Le Mans Hypercar project officially takes the green flag for the first time. The hypercar will be powered by a 5.4-litre naturally-aspirated V8 engine derived from the Mustang’s 5.0-litre Coyote. Those engines are pretty much the same ones the company already uses in the Mustang GT3 in both IMSA and FIA World Endurance Competition.
