The Mack Anthem is a series of heavy duty (Class 8) trucks built by Mack Trucks. It has a long low-drag hood and fenders. It is designed as a highway semi-tractor with good fuel economy. Introduced in 2018, it remains in production in 2020.
The Anthem is a long-hood 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 62,000 pounds (28,000 kg) and 80,000 pounds (36,000 kg) including all trailers.
Advanced electronics are used for engine, chassis, and body controls, as well as maintenance. The Anthem can also be equipped with front and side collision warning systems, adaptive cruise control, lane departure warning systems, and Mack Road Stability.
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.
The Anthem is available with three Mack diesels.
The Mack MP7 engine is the base engine in the Anthem. It is a 659 cubic inches (10.8 l) overhead cam turbocharged inline six-cylinder engine. It develops 235 to 434 horsepower (175 to 324 kW) and 1,200 to 1,560 pound force-feet (1,630 to 2,120 N⋅m) of torque.
The Mack MP8 engine is a 783 cubic inches (12.8 l) overhead cam turbocharged inline six-cylinder engine. It develops 434 to 505 horsepower (324 to 377 kW) and 1,460 to 1,760 pound force-feet (1,980 to 2,390 N⋅m) 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.
All Mack transmissions have aluminum cases and three countershafts. Multiple countershafts (Fullers have two) allows smaller countershaft gears to spread the load between them and allow easier shifting. Manual transmissions have five or six main gears, extra ratios are made with different combinations of ranges. 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. Other Mack manual transmissions have 8-18 speeds.
Eaton-Fuller UltraShift automated shifting systems are available on all of their transmissions from 9- to 18-speeds.
Allison RDS series 6- or 7-speed transmissions are available. The RDS is a fully automatic planetary gear transmission with a lock-up torque converter.
