The '''Mack Anthem''' is a series of heavy duty ([[Truck classification#Class 8|Class 8]]) trucks built by [[Mack Trucks]] over 2 generations since 2018. It has a long low-drag hood and fenders. It is designed primarily for highway use.
== Design == The Anthem is a long-hood [[Cabin (truck)|conventional]]. Designed for highway use, it can have a day cab or two different sleeper compartments. It has aerodynamic aids standards and others are available. Normally a 6x4 (3 axles, 2 powered), there are also 6x2 (3 axles, one powered) models. Total loaded weight can be up to {{convert|62,000|lb}} and {{convert|80,000|lb}} including all trailers.
Advanced electronics are used for engine, chassis, and body controls, as well as maintenance.
In 2019 a new generation [[Bendix Corporation|Bendix]] Wingman Fusion was available in the Anthem. It uses radar and cameras to provide emergency braking, lane departure, and blind spot warnings.<ref>{{cite web |url=https://thebrakereport.com/next-generation-bendix-wingman-fusion-offers-greater-driver-assistance-solidifies-foundation-autonomous-future/ |title= Next Generation of Bendix Wingman Fusion Offers Greater Driver Assistance and Solidifies Foundation for Autonomous Future| website =The Brake Report|date=September 6, 2018|archive-url = https://web.archive.org/web/20211201221426/https://thebrakereport.com/next-generation-bendix-wingman-fusion-offers-greater-driver-assistance-solidifies-foundation-autonomous-future/ | archive-date = 2021-12-01 | publisher = Hagman Media Group }}</ref>
Mack builds their own major components (engines, transmissions, axles, and suspensions) and promotes an integrated design. Most vendor components are also available, but engine choice is very limited.
In 2025, a new generation was introduced.
== Engines == The Anthem is available with three Mack diesels, the MP7, MP8, and MP8HE. A Cummins Westport ISX12N natural gas engine is also available<ref name=aspecs>{{cite web|title=Anthem specifications|url=https://www.macktrucks.com/trucks/anthem/specs/|website=Mack Trucks|date=2020|access-date=January 14, 2021}}</ref>
The Mack MP7 is the base engine in the Anthem. It is a {{convert|659|cuin|L|1|adj=on}} [[Overhead camshaft|overhead cam]] [[Turbocharger|turbocharged]] [[Straight-six engine|inline six-cylinder]] [[Diesel engine|diesel]] engine. It develops {{convert|325|to|425|hp}} and {{convert|1260|to|1560|lb.ft}} of torque.<ref>{{cite web|title=MP7|url=https://www.macktrucks.com/powertrain-and-suspensions/engines/mp7/|website=Mack Trucks|date=2020|access-date=January 14, 2021}}</ref>
The Mack MP8 engine is a {{convert|783|cuin|L|1|adj=on}} overhead cam turbocharged inline six-cylinder diesel engine. It develops {{convert|434|to|505|hp}} and {{convert|1460|to|1760|lb.ft}} of torque.
The Mack MP8HE engine is a variant of the MP8 with a mechanical drive behind the turbocharger in the exhaust stream. This allows more heat energy to be used for better fuel economy.
The [[Westport Innovations|Cummins Westport]] [[Cummins X-series engine|ISX12N]] is a {{convert|762|cuin|L|1|adj=on}} overhead cam turbocharged inline six-cylinder [[Natural gas vehicle|natural gas engine]]. It develops {{convert|400|hp}} and {{convert|1450|lb.ft}} of torque.<ref>{{cite book|url=https://www.cumminswestport.com/content/841/ISX12N_5544037_0418.pdf|title=ISX12N sales brochure|year=2018|publisher=Cummins Westport|access-date=January 15, 2021|archive-date=January 22, 2021|archive-url=https://web.archive.org/web/20210122235020/https://www.cumminswestport.com/content/841/ISX12N_5544037_0418.pdf|url-status=dead}}</ref>
== Transmissions == All Mack transmissions have aluminum cases and three countershafts. Both Mack and Fuller have manual and automated shifting models. Allison transmissions are available as fully automatic only.
Mack mDRIVE automated manual is the base transmission. It has no clutch pedal and shifts itself on demand. The driver can override it but it is normally driven in "D". It can have 12, 13, or 14-speeds.<ref>{{cite web|title=Mack Transmissions|url=https://www.macktrucks.com/powertrain-and-suspensions/transmissions/|website=Mack Trucks|date=2020|access-date=December 28, 2020}}</ref> Other Mack manual transmissions have 8-18 speeds.
[[Eaton Corporation|Eaton-Fuller]] UltraShift automated shifting systems are available on all of their transmissions from 9- to 18-speeds.
[[Allison Transmission|Allison]] RDS series 6-speed transmission is available. The RDS is a [[Automatic transmission|fully automatic]] planetary gear transmission with a lock-up torque converter.
== Frame == A ladder frame with beam axles is used. There is a single front axle on semi-elliptical [[leaf spring]]s. The base rear suspension is a Mack tandem with two powered axles, a single rear drive axle with an undriven pusher axle is available. Wheelbases are from {{convert|174| to |203|in|cm}}
A set-back front axle is used. Set back axles, where the hood extends in front of the axle, are used when overall length is not important. They let the fenders and bumper taper back to the tires, allowing less wind drag.
In 2020 Mack introduced the Command Steer system. An additional on-demand electric power steering system on top of the hydraulic system. This allows easier steering, will help dampen steering feedback, steady driving, and can compensate for side-winds, uneven pavement, and braking on different surfaces. A very light feel and automatic return-to-center feature are useful off-road, at slow speed, and in backing.<ref>{{cite journal|url=https://www.truckinginfo.com/351854/mack-adds-active-steering-option-anthem-daycabs-gain-smartway-badge |title=Mack Adds Active Steering Option|journal=Heavy Duty Trucking|date=February 25, 2020|access-date=January 19, 2021}}</ref>
[[Dana Incorporated|Dana-Spicer]] and [[Meritor]] supply [[Air brake (road vehicle)|air brakes]], driveshafts, and other components.
== Axles ==
Front axles are available in {{convert|12,000| and |14,000|lb}} ratings from Mack, Dana-Spicer, and Meritor.
Mack powered axles have the drive carrier on top of the housing instead of the front of it like other manufacturers. This lets the driveshafts be in line from the transmission to and between the axles.
Other powered axles are available from Dana-Spicer and Meritor. These have front mounted carriers and in tandemsthe two axle housings are different. The mRIDE tandem has tapered leaves that rock above the bogey pivot then go out and above the axles. Struts go from the bottom of the bogey pivot out and under the axle. They are rated at {{convert|40,000|, |46,000|, and |52,000|lb}}.
The Twin Y air suspension has trailing arms that fork to the rear and attach to both the top and bottom of the axle. There is an air bag behind the axle. Each axle is sprung individually. They are rated at {{convert|40,000|lb}}.
A Liftable pusher axle is used in a 6x2 arrangement, where only the rear axle is driven. They are lighter, have less drag, and can be raised when not needed. This allows better fuel economy and longer tire life.
Other tandems with mechanical or air suspensions are available from Mack, Chalmers, and [[Hendrickson International|Hendrickson]].
== Applications == The Anthem is designed as a fuel-efficient highway semi-tractor only.
Regional service is when runs are one day long. Regional tractors usually have a day cab, short wheelbase, and are often used for fleet service. They often can be used with a lower power engines and/or a 6x2 (three axles, rear only driven) arrangement.
Over-the-road is when one or two drivers live in the cab for extended periods. Over-the-road tractors are often owned by their drivers. With sleeper compartments and longer wheelbases they usually need more powerful engines than regional tractors.
