2020 Kenworth T680: Quick Overview
- Engine Options: The primary engine for the 2020 Kenworth T680 is the PACCAR MX-13. Drivers could also opt for the Cummins X15, offering a broader range of power outputs.
- Horsepower: The PACCAR MX-13 typically ranged from 405 to 510 horsepower with torque ratings from 1,450 to 1,850 lb-ft. The Cummins X15 offered similar ranges, often preferred for specific heavy-haul or performance needs.
- Fuel Economy: Designed for efficiency, the T680 consistently delivers strong fuel economy for a Class 8 truck. Averages can range from 6.5 to 8.5 MPG or even higher under ideal conditions, heavily dependent on engine, gearing, load, and driving habits. Kenworth's aerodynamic package contributes significantly to these figures.
- 0-60 Times: For Class 8 trucks like the T680, 0-60 mph times are not a relevant performance metric and are not typically published. Acceleration is focused on pulling heavy loads efficiently rather than rapid sprint speeds.
- Towing Capacity: As a Class 8 tractor, its "towing capacity" is better described by its Gross Combination Weight Rating (GCWR), which commonly ranges from 80,000 lbs to over 100,000 lbs, depending on axle configuration, engine, and application.
- Trim-Level Features: The T680 was available in various configurations from day cabs to multiple sleeper sizes, including a 76-inch Mid-Roof and High-Roof sleeper.
- Interior Packages: Offered multiple interior trim levels, such as the Vantage and Diamond VIT, which included premium materials, enhanced insulation, and more storage.
- Sleeper Amenities: High-roof sleepers often featured ample standing room, a double bunk option, swivel passenger seat, full-size refrigerator, microwave shelf, television mounts, and extensive cabinetry.
- Driver Comfort: Ergonomic dash layout with a 7-inch Kenworth TruckTech+ display, comfortable air-ride seats, and a quiet cab environment were standard across trims.

What Problems Does the 2020 Kenworth T680 Have?
The 2020 Kenworth T680, while generally reliable, has faced some common issues, many of which are typical for modern Class 8 trucks with advanced emissions systems. Frequently reported problems often revolve around the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems. Owners sometimes experience clogged DPFs, faulty DEF (Diesel Exhaust Fluid) sensors, or issues with the SCR injector, leading to "derate" conditions and reduced power. These issues are not exclusive to Kenworth but are a persistent challenge across the industry for models of this era.
Electrical problems, though less common, can manifest as issues with dashboard gauges, lighting, or the PACCAR infotainment system. Sensor failures, particularly those related to exhaust gas temperature or pressure, have also been reported, triggering "check engine" lights.
Regarding recalls for the 2020 model year, several were issued, some of which were broad and affected multiple PACCAR vehicles. Examples include recalls for potential fuel line leaks, which could pose a fire risk, and issues with brake systems or steering components that required inspection and potential replacement. Other recalls addressed software glitches in the engine or transmission control modules, impacting performance or emissions compliance. Owners should always check the NHTSA database for specific recalls pertaining to their VIN to ensure all necessary fixes have been applied.
Long-term reliability concerns typically extend to the longevity of emissions components, which can be costly to repair or replace after high mileage. Proper and diligent maintenance, including regular DPF regeneration and DEF system flushing, is crucial to mitigating these risks and ensuring the T680 achieves its expected lifespan of over a million miles.

How long will the 2020 Kenworth T680 last?
The 2020 Kenworth T680, like most well-maintained Class 8 trucks, is built for extensive service. Owners frequently report these vehicles achieving over 1,000,000 miles, with many reaching 1.2 to 1.5 million miles before major powertrain overhauls. Average years of service can easily exceed 10-15 years for an owner-operator or even longer for a fleet with rotation.
Long-term durability is strong for core components like the PACCAR MX-13 or Cummins X15 engines and Eaton transmissions. However, weaknesses tend to emerge in auxiliary systems. Over time, emissions components (DPF, SCR) will likely require significant maintenance or replacement. Air conditioning systems, various sensors, electrical wiring, and interior wear-and-tear items are also common points of failure or degradation with high mileage. Diligent preventative maintenance and prompt repairs are paramount to achieving maximum lifespan and minimizing costly downtime.
