The 2020 Mack Granite is a versatile vocational truck, building on Mack's legacy of ruggedness. Primarily offered as a conventional cab, it has been a staple in construction, refuse, and heavy-haul applications for many years, with the 2020 model year continuing this tradition. Key trims often revolve around axle configurations and specialized body options. Its popularity stems from its robust build, customizable configurations, and strong performance in demanding environments, making it a workhorse for businesses.
The Good
The 2020 Mack Granite boasts exceptional performance for tough jobs, legendary reliability that inspires confidence, and surprising driver comfort for long shifts. Its durable design is built to last, offering excellent value through its longevity and operational efficiency.
The Bad
Potential weaknesses for the 2020 Mack Granite can include its less refined ride compared to on-highway trucks, higher fuel consumption in certain configurations, and the initial cost of advanced technology options. Regular maintenance is crucial for optimal performance.
2020 Mack Granite: Quick Overview
- Engine Options: The 2020 Mack Granite typically features Mack's own powerful MP engines. Common options include the Mack MP7 (10.8L) and the Mack MP8 (12.8L).
- Horsepower: Horsepower ratings vary by engine and configuration. The MP7 can range from approximately 250-350 horsepower, while the MP8 can offer power from around 380-505 horsepower. Torque figures are also significant, with the MP8 often exceeding 1,800 lb-ft.
- Fuel Economy: Fuel economy is highly dependent on the specific engine, transmission, axle ratios, and the vocational application. As a heavy-duty vocational truck, MPG figures are generally lower than light-duty vehicles and are measured in GPM (gallons per mile) or presented as a range for specific tasks. Exact figures are not standardized and vary greatly.
- 0-60 Times: 0-60 mph times are not a standard metric for vocational trucks like the Mack Granite, as their primary purpose is not acceleration but rather heavy hauling and specialized work. Performance is measured by tractive effort and ability to climb grades with heavy loads.
- Towing Capacity: Towing and hauling capacities are exceptionally high and depend heavily on the specific configuration, including the number of axles, Gross Vehicle Weight Rating (GVWR), and Gross Combination Weight Rating (GCWR). Configurations can be built to handle Gross Combination Weights well over 100,000 lbs, making them suitable for severe service towing and hauling.
- Trim-Level Features: Trims are generally defined by their chassis configuration and vocational purpose. Key features include:
- Axle Configurations: Various front and rear axle options (e.g., single, tandem, tridem) to meet specific weight distribution and load-carrying needs.
- Suspension Systems: Robust suspension options like Mack's proprietary suspensions (e.g., AL407, AL460) designed for durability and load capacity.
- Cab Options: Standard day cabs are most common, but sleeper options may be available for longer routes.
- Body Upfitting Capabilities: Designed for easy integration with various vocational bodies such as dump bodies, concrete mixers, fire apparatus, refuse collection systems, and cranes.
- Powertrain Integration: Customizable transmission options, including manual and automatic transmissions from manufacturers like Allison and Eaton.

What Problems Does the 2020 Mack Granite Have?
The 2020 Mack Granite, like most heavy-duty vocational trucks, is built for extreme durability. However, common areas that owners and operators report concerns or require attention over time include:
Electrical System Issues: While generally robust, complex electrical systems in modern trucks can sometimes present intermittent faults. This could range from sensor issues to problems with the dashboard displays or lighting systems. These can be more prevalent as the vehicle accumulates mileage and operates in harsh conditions.
Emissions System Components: Modern diesel engines are equipped with complex after-treatment systems (DPF, SCR) to meet emissions standards. Components within these systems, such as DPF filters needing regeneration or SCR sensors, can sometimes require maintenance or replacement. While not necessarily a defect, it's a known aspect of owning and operating modern diesel trucks.
Wear and Tear in Vocational Applications: The primary reason for the Granite's existence is vocational use, which often involves significant stress on components. Items like suspension parts, brakes, and chassis components can experience accelerated wear due to constant heavy loads, rough terrain, and frequent stop-and-go operation inherent in construction, refuse, or other similar industries.
Cooling System: Overheating issues can sometimes arise, particularly in demanding applications where the engine is under sustained high load, especially in warmer climates. This could be related to radiator performance, fan operation, or coolant leaks.
Recalls: Specific recalls for the 2020 model year would need to be checked against official NHTSA databases for the VIN. Mack, like all manufacturers, issues recalls for safety-related defects. These can range from minor software updates to more significant component replacements. For instance, recalls in recent years for similar heavy-duty trucks have sometimes involved issues with braking systems, steering components, or electrical harness concerns.
Long-Term Reliability: Mack trucks, in general, have a reputation for strong long-term reliability when properly maintained. The Granite's straightforward, heavy-duty design contributes to this. However, the longevity of any vocational truck is heavily influenced by the severity of its use, the quality of maintenance performed, and the operating environment. Neglecting routine maintenance, especially fluid changes and filter replacements, can lead to accelerated wear and more significant problems down the line.

How long will the 2020 Mack Granite last?
The 2020 Mack Granite is engineered for longevity, typically operating for well over a million miles in some applications with diligent maintenance. Owner data and industry averages suggest that, with a consistent and comprehensive maintenance schedule (including regular oil changes, filter replacements, and chassis lubrication), these trucks can serve effectively for 10-15 years or more. Their robust construction and heavy-duty components contribute to significant long-term durability. Weaknesses that may emerge over extended service life, even with good maintenance, often relate to the cumulative wear on high-stress components like suspension, brakes, and exhaust after-treatment systems, particularly in severe vocational duty cycles. However, the core powertrain and chassis are designed to withstand substantial mileage.
What Technology & Safety Features are Included?
The 2020 Mack Granite is primarily a vocational workhorse, and its technology and safety features are geared towards operational efficiency and driver support in demanding environments. While not laden with luxury car-like infotainment, it offers practical technology:
Built-in Tech & Entertainment: Standard offerings typically include an AM/FM radio, and often a digital display for vehicle diagnostics and system information. Bluetooth connectivity for hands-free calling is often available or optional, enhancing driver convenience and safety by minimizing distractions. For more advanced systems, optional infotainment units with touchscreens, navigation, and integrated audio systems can be specified, catering to longer haul vocational routes.
Driver-Assistance Features: While advanced driver-assistance systems (ADAS) are less common as standard on base vocational models compared to consumer vehicles, many are available as options. These can include:
Crash-Test Ratings: It is important to note that heavy-duty commercial trucks like the Mack Granite are not typically subjected to the same standardized crash-test rating procedures (like NHTSA's frontal or side impact tests for passenger cars) due to their size, weight, and vastly different use cases. Instead, their safety is assessed through industry standards for component strength, structural integrity, and the availability of advanced safety systems designed to prevent accidents in the first place. Manufacturers like Mack focus on meeting and exceeding regulatory requirements for commercial vehicles.
