The 2016 Kenworth T660 is a vocational truck known for its aerodynamic design and fuel efficiency. Primarily available as a conventional cab tractor, it served the North American market from 2008 through 2016. Key trims often revolved around engine and spec configurations tailored for specific hauling needs. Its popularity stems from a blend of driver comfort, operational efficiency, and Kenworth's reputation for quality. New pricing varied widely based on configuration, but used models typically range from $40,000 to $80,000 depending on age, mileage, and condition.
The Good
The 2016 Kenworth T660 offers exceptional fuel efficiency and a comfortable, driver-centric cabin. Its robust performance and renowned reliability provide peace of mind, while the modern, aerodynamic design appeals to both pride and practicality, making it a smart investment for owner-operators and fleets.
The Bad
Potential owners of the 2016 Kenworth T660 should be aware of possible electrical system gremlins, particularly with older units. Some drivers have reported issues with exhaust gas recirculation (EGR) systems and cabin noise intrusion. Regular maintenance is crucial to mitigate these potential concerns.
2016 Kenworth T660: Quick Overview
- Engine Options: The 2016 Kenworth T660 was primarily equipped with PACCAR MX-13 engines, known for their efficiency and power. Other Cummins ISX15 engines were also available in some configurations.
- Horsepower: PACCAR MX-13 engines typically ranged from 400 to 500 horsepower, with torque figures often between 1,450 and 1,850 lb-ft.
- Fuel Economy: Specific MPG figures are highly variable for heavy-duty trucks and depend heavily on load, terrain, driving style, and axle ratios. However, the T660's aerodynamic design was a key selling point for maximizing fuel efficiency, often achieving numbers significantly better than less aerodynamic competitors, potentially in the 6-8 MPG range under optimal conditions.
- 0-60 Times: 0-60 mph times are not a standard metric for Class 8 trucks as their focus is on hauling capacity and sustained speed under load, not rapid acceleration.
- Towing Capacity: The towing capacity is determined by the Gross Combination Weight Rating (GCWR), which can exceed 80,000 pounds, and is configured based on the chassis, engine, and drivetrain specifications for specific applications.
- Trim-Level Features: While not having distinct 'trims' in the passenger car sense, the T660 offered various spec packages and options that defined its capability. These included:
- Aerodynamic Package: Features like a sloped hood, aerodynamic mirrors, and chassis fairings to reduce drag.
- Sleeper Options: Available in various sleeper sizes (e.g., 40-inch, 52-inch, 62-inch, 73-inch) for long-haul comfort, with amenities like beds, storage, and sometimes even refrigerators.
- Interior Options: Choices for driver comfort and functionality, including upgraded seating, enhanced dashboard layouts, and premium materials.
- Chassis Configurations: Available in different wheelbases and axle configurations to suit vocational needs.
- Transmission Options: Typically offered with manual transmissions (e.g., Eaton Fuller) or automated manual transmissions (AMTs).

What Problems Does the 2016 Kenworth T660 Have?
The 2016 Kenworth T660, like many heavy-duty trucks, can experience issues that are often tied to the complexity of modern diesel powertrains and their operating environment. One area frequently mentioned by owners and technicians involves the Exhaust Gas Recirculation (EGR) system. Problems can include clogged EGR coolers or valves, leading to reduced engine performance, increased emissions, and potential check engine lights. While not specific to the 2016 model year, these are known concerns for PACCAR engines of that era, especially if the truck has been subjected to frequent short-haul cycles or has not had proper maintenance.Electrical gremlins are another reported issue. This can manifest as intermittent warning lights, faulty sensor readings, or issues with auxiliary systems. Given the intricate wiring harnesses and numerous electronic control modules (ECMs) in modern trucks, diagnosing and repairing electrical problems can be complex and costly. Drivers have sometimes reported issues with the infotainment system or cabin electronics, though these are generally less critical than powertrain concerns.Fuel system components, such as fuel injectors and pumps, can also be a source of problems over time, especially with varying fuel quality. The aftertreatment system (DEF/DPF), while designed to meet emissions standards, can also require maintenance and occasionally experience issues like clogged filters or faulty sensors, particularly if drivers do not allow the system sufficient time to regenerate. Specific recalls for the 2016 model year would need to be checked against the National Highway Traffic Safety Administration (NHTSA) database, but common recalls for trucks of this era often relate to braking systems, steering components, or potential fire hazards from certain electrical connections or fuel line issues. Long-term reliability heavily depends on the truck's maintenance history, how it was operated (e.g., type of hauling, driving habits), and the quality of repairs performed. Trucks that have been meticulously maintained with regular fluid changes, filter replacements, and timely attention to minor issues tend to be far more reliable over the long haul than those neglected.
How long will the 2016 Kenworth T660 last?
The 2016 Kenworth T660 is built for durability and can achieve significant mileage. Owner data and maintenance habits are paramount. Well-maintained T660s can routinely surpass 500,000 to over 1,000,000 miles in service. The PACCAR MX-13 engine is generally robust, but long-term care of the aftertreatment system, EGR, and regular fluid maintenance are crucial. Weaknesses that can emerge over time include potential electrical system issues and wear on suspension and drivetrain components, especially if subjected to heavy vocational use. With diligent preventative maintenance, these trucks can offer decades of reliable service, making their longevity a strong selling point.
What Technology & Safety Features are Included?
The 2016 Kenworth T660, while focused on robust functionality, offered a decent array of technology and safety features for its class and era. Built-in tech primarily revolved around the driver's operational needs. The dashboard typically featured clear, analog gauges for critical functions, complemented by a digital display for system diagnostics and trip information. Entertainment features were often basic, focusing on AM/FM radio, CD players, and auxiliary inputs, with optional satellite radio for long-haul drivers. More advanced infotainment systems with larger touchscreens and navigation were available on higher-spec models or as aftermarket additions.
Driver-assistance features were less prevalent and sophisticated compared to modern passenger vehicles. However, options could include features like cruise control, and potentially advanced systems such as lane departure warnings or forward collision mitigation, though these were not standard across all configurations. The primary focus was on systems that aided driver visibility and control, such as powerful lighting and responsive braking systems.
Safety features were paramount. The robust frame and cab construction were designed to offer significant protection. Standard safety equipment included anti-lock braking systems (ABS) for improved stopping control. Optional features could extend to enhanced lighting for visibility in adverse conditions, heated mirrors to prevent fogging, and sometimes, specialized aerodynamic mirrors that reduced blind spots. Air suspension systems could also contribute to a more stable ride, indirectly enhancing safety.
Crash-test ratings are not typically published for Class 8 trucks like the Kenworth T660 in the same way they are for passenger cars by organizations like the NHTSA or IIHS. The design and engineering of these vehicles prioritize occupant protection through their sheer size, strength, and specific safety systems designed for commercial trucking operations. Their inherent structural integrity, along with features like reinforced cabs and advanced braking systems, are considered their primary safety contributions.
