Freightliner has confirmed production of the 2018 Cascadia is underway.

The first models off the line will go straight to the American market, with no confirmation of as to when it will hit Australian roads.

Speculation about the future of the Argosy also continues, with Australia and South Africa now the only markets for the model.

The new Cascadia boasts up to an eight per cent fuel economy increase over a similar spec 2016 Cascadia Evolution.

“It’s exciting to see trucks rolling off the assembly line and being delivered to customers. The new Cascadia delivers fuel efficiency, connectivity, safety, quality and a premium driver experience for our customers,” said Kary Schaefer, general manager of marketing & strategy for Daimler Trucks North America.

The Cascadia comes fitted with Detroit Diesel’s DD15 or DD13 engine with a 400 horsepower rating, mated with a DT12 automated manual.

Additional improvements include gauge and switch layouts, a new driver loft configuration aimed at customizing living space to address the realities of professional drivers, a redesigned sleeper area with sturdy television swivel, optional folding workspace/dinette and a full-sized Murphy style bed and cargo shelf option.

The vehicle will also include new splayed frame rails and most electronic control units will be stored securely in the cab in the new eVault for easier convenience and protection from the elements.
