Caterpillar’s Foray into Highway Trucks
Caterpillar Inc., founded in 1925, built its global reputation on earthmoving equipment, mining machinery, and industrial engines. In 2011, the company made a bold move into the on-highway truck market by launching the CT Series, a line of vocational trucks aimed at construction, waste hauling, and heavy-duty transport. These trucks were built in partnership with Navistar, using International chassis and Caterpillar branding, with CAT’s own engines and styling.
The CT660 was the flagship model, designed to compete with Kenworth, Peterbilt, Mack, and Freightliner in the Class 8 vocational segment. It featured:
Terminology Notes
Several factors contributed to the CT Series’ short lifespan:
A Story from the Midwest
In 2014, a contractor in Illinois purchased a fleet of CT660 dump trucks for municipal roadwork. Initially impressed by the rugged design and CAT branding, the team soon faced repeated engine faults and difficulty sourcing parts. After two years, the trucks were phased out and replaced with Mack Granite models. The fleet manager noted, “They looked tough, but they weren’t built for the long haul.”
Strategic Implications of the Exit
Caterpillar’s withdrawal from the on-highway truck market reflects a broader industry trend: specialization over diversification. While the CT Series was an attempt to leverage brand loyalty, it revealed the challenges of entering a mature, highly competitive segment without deep infrastructure.
Key lessons include:
Recommendations for Fleet Managers
For those considering vocational truck purchases:
Final Thoughts
Caterpillar’s brief venture into the on-highway truck market was ambitious but ultimately unsustainable. The CT Series offered bold styling and brand recognition, but lacked the mechanical pedigree and dealer infrastructure needed to compete. Its exit underscores the importance of strategic alignment and customer trust in vocational trucking. In the end, Caterpillar returned to what it does best—building machines that move the earth, not just drive across it.

These trucks were built in partnership with Navistar, using International chassis and Caterpillar branding, with CAT’s own engines and styling.
The CT660 was the flagship model, designed to compete with Kenworth, Peterbilt, Mack, and Freightliner in the Class 8 vocational segment. It featured:
- CAT CT13 engine, based on Navistar’s MaxxForce
- Gross vehicle weight rating (GVWR): up to 92,000 lbs
- Configurations for dump, mixer, and lowboy applications
- CAT-branded cab interiors and exterior styling
Terminology Notes
- Vocational truck: A heavy-duty vehicle designed for specific tasks like hauling, dumping, or mixing, rather than long-haul freight.
- Class 8 truck: A truck with a GVWR over 33,000 lbs, typically used for the heaviest commercial applications.
- CT Series: Caterpillar’s line of on-highway vocational trucks, including the CT660, CT680, and CT681.
- MaxxForce engine: A diesel engine developed by Navistar, known for its emissions challenges in the early 2010s.
Several factors contributed to the CT Series’ short lifespan:
- Engine reliability concerns: The CT13 engine, derived from Navistar’s MaxxForce, had a reputation for emissions-related failures.
- Dealer network limitations: CAT dealers were experienced in off-road equipment but lacked infrastructure for highway truck service.
- Market saturation: Established brands like Mack and Kenworth dominated the vocational segment with proven platforms.
- Customer skepticism: Many fleet managers were hesitant to adopt a new truck line with limited field history and uncertain resale value.

Key lessons include:
- Dealer readiness matters: Highway trucks require a different service model than construction equipment.
- Engine platform trust is critical: Customers prioritize reliability and emissions compliance.
- Brand strength alone isn’t enough: Even iconic names must prove value in new markets.
Recommendations for Fleet Managers
For those considering vocational truck purchases:
- Evaluate dealer support and parts availability
- Prioritize proven engine platforms with strong emissions track records
- Consider resale value and long-term service costs
- Avoid niche models with limited production runs unless backed by strong warranties
