About Cascadia

The Cascadia is the backbone of North American long-haul trucking. Introduced in 2007 as the replacement for Freightliner's Century Class, it was designed from the start around aerodynamics and fuel economy, the two things fleet managers care about most. Its smooth, sloping hood and integrated fairings made it one of the most efficient trucks of its era, and it quickly became the default choice for big fleets. Today it is the best-selling Class 8 tractor in the region, a familiar shape at every truck stop from Laredo to Lethbridge.

A thoroughly redesigned Cascadia arrived later in the 2010s with improved aerodynamics, a more comfortable cab and integrated Detroit powertrains, and a fifth generation followed with further gains in efficiency and safety technology. Each update has focused on reducing fuel consumption, which can save fleets thousands of dollars per truck each year, while improving driver comfort, since retaining good drivers is one of the industry's biggest challenges. Drivers praise the quiet cab and spacious sleeper options, while some owner-operators prefer the more traditional styling of rivals.

The Cascadia is offered in day-cab and sleeper configurations, with Detroit DD13 and DD15 diesel engines, the DT12 automated manual transmission and the Detroit Assurance suite of safety systems, including active brake assist and lane-keeping functions. The battery-electric eCascadia brings zero-emission capability to regional routes. It competes with the Peterbilt 579, Kenworth T680, Volvo VNL, International LT and Mack Anthem in one of the most fiercely contested segments of the commercial vehicle market.

This page covers updates and new model years, safety and technology features, fuel-efficiency testing, electric and autonomous developments, recalls and used-truck values. Watch for how the Cascadia adapts to stricter emissions standards, the growth of the eCascadia and autonomous versions being tested with technology partners, and the digital features that increasingly define the modern truck. For a vehicle that moves so much of the continent's freight, even small changes can ripple through the economy, and its sales figures are watched as an indicator of trucking's health.
