Test Drive

Another impressive feature was the lack of noise. Though we admittedly tread lightly on the surface streets, there was no cab-produced noise, no booming or rattling. On the freeway, the truck settled into a quiet cruise, showing sound levels comparable with – or even a shade quieter than – the International ProStar+ and the Volvo VN.

The quiet ride, along with the multi-adjustable suspension seats, help relax the driver. A three-compartment cushion provides excellent lumbar support.

The Cascadia is all about size. It is wide and tall inside and a comfortable truck whether you’re driving or resting. The cab width allows for seats two inches wider, longer and taller. Yet even with the wide seats, there’s 24 inches of walk-through to the standard 72-inch high roof sleeper, which has 94 inches of stand-up room. The seats are on swivels so they can double as armchairs when logging off-duty sleeper time.

Another distinctive feature is the small windows in the sleeper. They don’t help with fuel economy, but they do eliminate the potential water leakage path with the conventional mounting of glass in rubber. At the launch in 2007, Freightliner said research showed drivers didn’t particularly care about seeing out of the sleeper, but they did care about others seeing in. Eliminating the lower side windows at the time seemed an easy decision. But they are back, as is a sleeper door, as an option.

The Freightliner Cascadia’s bumper is in three pieces – as is the hood – for quick and inexpensive repair. For the same reason, the huge windshield is a two-piece roped-in design. The aluminum cab is designed to withstand not just the standard ECE 29 crash test, but the far more rigorous Swedish cab test requirements.
