The combat "N Series" (NB, NJU, NM, NO, NR, etc.) accounted for 26,965 of the total. Commercial type vehicles including: trucks, off-highway, fire-trucks, trailers, and buses, accounted for the rest. A total of 2,053 NO models alone were produced from 1940 to 1945. The 6x6 7-yard/2-ton NO was the most important specifically military model, and could be used as a transport or tractor for the 155 mm Long Tom field gun. Mack also built over 2600 power trains for tanks. The Allentown bus plant (5C) built VulteePBY Catalina flying boats as well as components for the BT-13 Valiant Trainer and B-24 Liberator Bombers. More than 700 NJU (5-to-6 ton 4x4) models were in the hands of the U.S. Army by 1942. In 1939 & 1940 the French and British received several hundred NR4 and EXBU models.

It was produced in 1955 and early 1956. The second styling included a styled grille, cab rear corner windows and stylish emblems and trim. The second styling was built from mid 1956 until the end of the D Model in 1958. A total of 832 D Model Mack Trucks were produced from 1955 until 1958.

1965: The R Model Series introduced, to replace the B Model Series. Some R series models continue in production until 2005.
Mack started to produce the R and U Model in the early 1960s for highway use, and the RD, DM, and all wheel drive RM and DMM Models for construction use. The lightweight RL model followed in 1967, and the setback front axle RB in the 1990s. All these models featured the same cab; the U, DM, and DMM had the cab offset to the left, and the early RD and DM had 3-piece steel hoods. They later had 1-piece hoods, the RD had a new hood, and the DM the U hood, although the 3-piece steel hoods remained optional. In the late 1990s, the R and U Models were discontinued and the RB was introduced, mostly for severe-duty applications. The hood was modified slightly for the model RB.
2004 was the last year for the RD, and 2005 for the RB and DM. The DM was the last model to use this cab style, and was the last model of this family to be produced. As a replacement for the construction models, Mack started to offer the Granite, Granite Bridge-Formula and Granite Axle-back, which feature a centered cab, which is not offset like the DM.
Also this model is serving in the Mexican Army as a Troop and Utility Truck in Configuration 6X6 OR 6X4
In the early 1960s, Mack Truck's executive vice president of product and engineering, Walter May, developed the Maxidyne high-torque rise engine. The engine was introduced as an inline six in 1966, as a 325 hp. V8 in 1970, and as the intercooled inline six 300 series in 1973. This was an industry-changing event. The Maxidyne, with an operating range of 1200-2100 R.P.M, and later 1050-1700 R.P.M., allowed a heavy Class 8 truck to be operated with a 5 speed (Maxitorque) transmission. Previously, heavy trucks typically operated between 1800-2100R.P.M. and were equipped with 10 or more gears.
The company's trademark is the bulldog. It can be found on the front of almost all Mack trucks. A Mack truck with a gold-plated bulldog indicates that the entire truck is made of Mack components. Trucks with another manufacturer's transmission, engine, rear axles or suspension are given the chrome-plated bulldog.
Mack trucks earned this nickname in 1917, during World War I, when the British government purchased the Mack AC model to supply its front lines with troops, food and equipment. British soldiers dubbed the truck the "Bulldog Mack", because they said it had "the tenacity of a bulldog." Its pugnacious, blunt-nosed hood, coupled with its incredible durability, reminded the soldiers of the tenacious qualities of their country's mascot, the British Bulldog.
The logo was first used in 1921 for the AB chain drive models and made the official corporate logo in 1922.
