Ford vehicles of all sizes – from Focus to F-Series Super Duty – go subzero testing in the U.S. military’s all-weather laboratory designed to re-create nearly every weather condition on earth.

Ford Motor Co is using the McKinley Climatic Laboratory at Eglin Air Force Base in Florida to push the limits of extreme cold-weather testing in order to improve vehicle quality and performance.
The carmaker has said that that each year it takes its global prototype vehicles and a team of engineers to the world’s largest climatic test and all-weather facility, which is used by the U.S. Air Force to test every aircraft in the Department of Defense inventory. Here, Ford engineers can get temperatures down as low as minus 40deg Fahrenheit in a span of just 10 hours. The hot, humid climate of northwest Florida in August has no impact on conditions inside the lab – making it ideal for simulating winter in Alaska’s Prudhoe Bay or Canada’s Yellowknife region.
So when it’s the middle of a development cycle, or the middle of summer, and there’s no access to a natural environment where engineers can evaluate whether a vehicle is starting as robustly as it should in below-freezing temperatures, McKinley Climatic Lab allows the carmaker to simulate, calibrate and validate – all under one roof.
The opportunity to accommodate 75 global prototype vehicles of all sizes for rigorous testing – plus house a versatile team of 54 engineers and technical experts – creates efficiency in the company’s product development cycle that helps Ford learn in just three weeks what could take twice as long in a smaller facility. Collecting multiple data sets, analysing results, and comparing and contrasting enables Ford engineers to quickly implement changes that enhance vehicle quality.
Optimum performance in the most extreme weather conditions means different things for customers in different parts of the world. That’s why Ford says its engineers strive to account for all variables when seeking assurance that customers who live and work in cold climates will be able to reliably start and run their vehicles in subzero temperatures. Specific situations engineers test for include:
In the oil fields of Alaska’s Prudhoe Bay, Ford F-Series trucks are not only a mode of transportation, but also a safety device for workers who need a warm cabin to retreat to on-site to prevent cold-weather injury on the job. Ford engineers conduct idle tests at the lab – running the engine week after week as temperature fluctuates from 40deg to minus 40deg, and examining the exhaust as it heats up then cools back down – to help ensure the needs of these customers are met
For those customers who depend on their vehicles for work commutes and to transport their families around town, testing at the lab ultimately seeks to provide them with the assurance that their vehicles are designed to start and run in the bitter cold. As temperatures in the lab drop to minus 22deg, Ford engineers examine the volatility of 13 different types of fuel commonly used by customers across the globe to calibrate the cold start
When running tests at such low temperatures inside McKinley Climatic Lab, engineers make changes daily to help ensure engine start and vehicle driveability. Learnings from these cold-weather tests have helped Ford engineers perfect the 6.7-litre engine that powers the current F-Series Super Duty. Engineers found that replacing metallic plugs with ceramic gold plugs enabled the engine to heat up more quickly, for a more robust start.
