The safest and most advanced truck we've ever built.
Technology gets tough in the all-new 49X, the first Western Star to feature the most advanced suite of active safety systems ever offered to the vocational market — Detroit Assurance. But it not only helps keep people safe, it helps you reduce the repair and operational costs of having a truck out of service by avoiding collisions — which can mean game-changing productivity to you. SIDE GUARD ASSIST A game changer for safety in and around busy jobsites, Side Guard Assist detects objects on the passenger side of the truck and alerts the operator. Active Brake Assist 5 Active Brake Assist 5 detects distance and speed to moving and stationary objects in its path and determines if braking is necessary. It's the only system on the market that works down to 5 MPH, making it ideal for travel in congested urban areas. It also recognizes pedestrians who are about to cross in the truck's path, alerting the operator while partially braking, followed by full braking if the operator does not react. Adaptive Cruise Control to 0 MPH and Tailgate Warning Detroit Assurance technology enables state-of-the-art features such as Adaptive Cruise Control to 0 MPH and Tailgate Warning to ease driving in stop and go traffic, as well as help mitigate front and rear collisions as operators travel from one jobsite to the next.
Tough on the outside. Very comfortable on the inside.
When your trucks work some of the toughest jobs around, you can't underestimate the importance of comfort. The interior of the all-new 49X has the space, the ergonomics and the quality finish that make the long days for operators in construction, logging, quarry and other demanding environments a lot more comfortable. THE 49X DAY CAB / SLEEPER The 49X cab represents a leap forward not just in technology but in comfort. In the sleeper, you'll find a number of features and options that let you create the living and working space your operators need when they're on the job for extended times.
