Reading by the warm fire, accompanied by a cup of tea, is a classic winter picture. However, for Ram Heavy Duty, who wrote his own book and prefers octane to Earl Grey, the perfect snow day is completely different. Cold is something to be embraced, not something to be hidden. This is an opportunity to improve Ram’s sense of purpose, and it now has first-class ratings in terms of fuel economy and traction.Ram Truck: Holden's Hero

We are going well north to Houghton, Michigan, where Ram takes merciless winter weather and literally “plows” through it. A series of intense vehicle tests, on a real world proving ground, that would swallow lesser automobiles. The conditions Ram endured recently in Houghton County show how surviving sub-zero weather in Michigan will later be duplicated on an assembly line and sold to the world.

Test #1 – Slush Packing

Driving through a wintry mix is difficult enough but how about parking afterwards? When everything collected underneath; the water, snow and slush combos become bricks of ice? It takes over the components and imprisons the entire undercarriage of the truck. Fuel lines, brakes, suspension components, the oil pan – all of these vital parts become grasped in winter’s cold hands.

Ram engineers drive the trucks through 12-inch-deep slush, then pull into special a refrigeration facility. They set the dial to minus 20, then returned the next morning to inspect the results. Did all the components underneath still meet their specifications?

“When it’s minus 20 outside and I walk up to my Ram Truck on a morning of a Michigan winter, I have a sense of self-reliance and assurance that my truck will start, warm up quickly and run well,” said Mike Cairns, Director of Ram Truck Engineering.

The diesel exhaust fluid tank and corresponding lines, made of materials to combat frost held up. A heating system keeping a portion of DEF above freezing allowed the engine to start. And because of the strategic location of vent lines, ice was unable to block them. This gave full function of the truck’s transmission, transfer case and windshield wipers.

Test #2 – Snow Ingestion

This one is just plain nasty. When seeing the designs for this test and the intent, I get goosebumps. Ram engineers literally force the trucks to breathe in massive amounts of snow, while running them for hours at a time.

Works like this: The lead truck pulls a chain link, grid device called a “drag.” When paraded through the snow it, kicks up whirlwinds of winter rage for the trucks following to drive through. This pushes the Ram Active Air intake system, the first of its kind in the automotive industry.

When vehicles encounter blowing snow, air filters can become clogged as the vehicle breathes. The resulting effects compromise the intake system and subtract performance. Yet, Ram trucks behind the “drag” breathed wonderfully, thanks to an under-hood inlet. This air path is protected from invading snow, ice and slush. The Ram Active Air intake system works intelligently too, switching “breathing patterns” depending on the driving conditions.Ram Truck: Holden's Hero

This helps the Ram lend its balance of fuel economy and power, be it a Michigan winter or Texas summer.

Test # 3 – Plow Power

80 percent of commercial and private plow trucks are 3⁄4-ton or greater and as Ram reaches that market, documenting the results of plow tests are vital. Ram engineers plow more than 10,000 tons of snow each winter as part of their ongoing research. Plow truck operators will take multiple passes in a small area, pushing forward and then reversing out. This is common in parking lots.

Think of how that constant shifting, from reverse to drive, puts increased strain on the transmission. Ram engineers use plow tests to see how the transmission holds up under pressure. One measure of merit for a truck is how efficiently and seamlessly it gets torque to the wheels. Plow testing is a measure of the same, except with a massive pile of snow now creating resistance.

Sometimes, we encounter that here in Michigan. Resistance. There are many negative stories about Detroit and the state in which she rests. However, what these tests show, more so than a capable truck, is how we as the American Automotive Industry face resistance.

With persistence.

And we take that persistence, bottle it up and mass-produce it. That creates jobs here and satisfied customers all across the globe.

Welcome to a typical day in Michigan . . . cold yet?

Ram engineering tested trucks with new and more “experienced” plows. V-shaped and straight plow combinations were used to cover a wide range of equipment.

Moving into the 2015 model year, Ram holds:

Best-in-class fuel economy with exclusive EcoDiesel – 29 mpg with Ram 1500

Best-in-class towing capability – 30,000 pounds with Ram 3500

Best-in-class payload – 7,390 pounds with Ram 3500

Best-in-class torque – 865 lb.-ft. with Ram 3500 equipped with Cummins

Ram Engineering conducted a large number of laboratory tests at the company's technology center in Michigan, and completed vehicle tests at the company's two main test sites in Arizona and Michigan. The goal is to ensure that all Ram trucks are fully capable of withstanding the harshest environments. In addition to Holden, Ram also traveled to Bemidji, Minnesota for a similar cold weather test.
