Freightliner Unveils Fifth-Generation Cascadia With New Safety Systems and Brake-by-Wire

Freightliner unveiled the fifth generation of its Cascadia on October 15, 2024, after showing the redesigned Class 8 tractor publicly for the first time at the American Trucking Associations' Management Conference & Exhibition.

Daimler Truck North America said customers had bought more than 1 million Cascadias since the model was introduced in 2007. The new version is the truck's first redesign in five years, Transport Topics reported. Series production is scheduled to begin in mid-2025, and DTNA said its order book would open later in 2024.

Safety systems

The update expands the Detroit Assurance safety suite with more computing power, an upgraded camera, four new short-range radar sensors and an improved long-range radar. DTNA said:

• Active Brake Assist 6 can now brake automatically for vehicles stopped at odd angles, vehicles in curves and stopped vehicles across multiple lanes, and can recognize stationary as well as moving pedestrians.
• Active Lane Assist 2 adds Lane Change Assist, which can counter-steer if the truck starts to move into an occupied lane.
• With lane keep assist active, the system monitors driver attention through steering input and can keep the truck centered, slow it to a stop and turn on the hazard lights if the driver does not respond.
• Side Guard Assist 2 now detects objects on the driver's side as well as the passenger side, from the cab to the end of the trailer.

Brakes, lights and mirrors

A new Intelligent Braking Control System combines brake-by-wire technology with backup pneumatics. It adds Comfort Braking, which distributes brake force and controls lining wear, and Endurance Braking, which blends the engine retarder with the service brakes when the pedal is pressed. A new electronic parking brake applies itself automatically if the driver leaves the seat or opens the door without setting the brake, to prevent rollaways.

New dual-stage LED headlights are designed to melt ice and clear condensation in minutes. "If you're in Alabama and you think, 'What do I need deicing for?' you actually need the defogging element," DTNA marketing communications director Samantha Parlier told TT. The MirrorCam camera system is now factory installed.

Efficiency and engines

DTNA said aerodynamic changes, including a new hood, a redesigned A-pillar deflector, a hood-to-bumper seal and new bumper air ducts, add a 1.9% fuel economy benefit. An optional Max Aero Bumper is also available.

At launch, the truck is offered with Detroit DD13 and DD15 engines rated up to 505 hp and 1,850 lb-ft of torque. Cummins X15 diesel and X15N natural gas engines, rated from 400 to 605 hp and 1,450 to 2,050 lb-ft, are to follow, with the X15N in 2026.

A new connected telematics platform adds remote lock and unlock, geofencing and Detroit Connect Video Capture 2.0, which records data during safety events.

"More safety features, greater efficiency and increased profitability is what we heard, and it's what we're proud to deliver," said David Carson, DTNA's senior vice president of sales and marketing.

What it means for drivers and fleets

For drivers, the October 2024 redesign brought features aimed at common hazards: automatic braking for stationary pedestrians, a parking brake that sets itself, warnings on both sides of the truck and a system that can bring the truck to a stop if the driver becomes unresponsive. Remote unlocking addresses a routine headache, since drivers locked out of the cab no longer need to wait for a locksmith. For fleets, the mid-2025 production start gave buyers time to plan spec changes and driver training for the new systems.
