Mack Trucks, Inc. is an American truck-manufacturing company and a former manufacturer of buses and trolley buses. Founded in 1900 as the Mack Brothers Company, it manufactured its first truck in 1907 and adopted its present name in 1922. Mack Trucks is a subsidiary of AB Volvo which purchased Mack along with Renault Trucks in 2000. After being founded in Brooklyn, New York, the company's headquarters were in Allentown, Pennsylvania from 1905 to 2009, when they moved to Greensboro, North Carolina. The entire line of Mack products is still produced in Macungie, Pennsylvania, with additional assembly plants in Pennsylvania, Maryland, Australia, and Venezuela.

Currently, the company's manufacturing facilities are located at the Macungie Assembly Operations plant in Lower Macungie Township, Pennsylvania. Mack Trucks is a top producer in the vocational, on-road-vehicle market, Class 8 through Class 13. It is also the most popular manufacturer of heavy-duty off-road trucks in America.
Mack trucks have been sold in 45 countries. The Macungie, Pennsylvania, manufacturing plant, located near its former Allentown corporate headquarters, produces all Mack products. The Mack MP-series engine, Mack transmissions, the TC-15 transfer cases, and rear engine power take-offs are designed and manufactured in Hagerstown, Maryland, which, according to local historians, was the original factory location.
Parts for Mack's right-hand-drive vehicles are produced in Brisbane, Queensland, Australia, for worldwide distribution. Assembly for South America is done at Mack de Venezuela C.A., in Caracas, Venezuela. The Venezuela operation is a complete knock down (CKD) facility. Components are shipped from the United States to Caracas, and the plant then does final assembly.
In addition to its Macungie manufacturing facility, Mack also has a remanufacturing center in Middletown, Pennsylvania, where it takes used parts and refurbishes them for resale/reuse.
2008 restructuring plan
On August 14, 2008, Mack Trucks announced a major restructuring plan that included:
- Relocation of Mack's head office, product development, most support functions, and purchasing functions to Greensboro, North Carolina, in 2009. Mack's parent, Volvo Trucks, already has its North American base in Greensboro.
- Assembly of all produced Mack highway vehicles in Macungie, Pennsylvania from 2008.
- Mack's testing facility in Allentown, Pennsylvania, will be converted into a "customer demonstration/reception center" in 2010.
- Restructuring the parts distribution network by 2010.
- Now delayed to 1st quarter 2011
- As of November 2009, assembly of Mack Highway product will shift to the Macungie Manufacturing Division. 100% of Mack's product will be assembled in Macungie.

Fire apparatus gallery
The heavy duty AC, with its well known tapered hood, was the truck which started the bulldog theme. A 377 cu in (6.2 L) 4 cylinder gasoline engine 4X2 with chain drive, it was strong, reliable, and worked well in rough terrain. Introduced in 1916, there was a great demand because of World War I, over 6000 3 1/2, 5 1/2, and 7 1/2 ton trucks were built for the UK and US military. There were also commercial sales from 1916, the AC was well suited for logging and construction work. A larger version, the AP, built between 1926 and 1938, was an off-road haul truck used on Boulder dam and other large projects. 40,299 ACs had been built when production ended in 1939.   
The N Series was Mack’s first military design, large 6 and 7 1/2 ton 6X6 artillery prime movers. Between its development in the late 1930s and the beginning of production in 1940 US military requirements changed and the truck was not needed. All NMs and most of the larger NOs were exported as foreign aid. After WWII the NO was developed into the successful M 123 semi-tractor. 
The B Models were Mack’s primary vehicle from its introduction in 1953 until it was replaced by the R Series in 1966. They ranged in size from the medium duty B20P gas powered 4X2 to the oversized B873SX turbo-diesel 6X6. B Models were commonly used as semi tractors and in the construction industry. They were also used as fire engines and trucks, sometimes with the roof of the cab removed. 127,786 B Models were built.  
R/RB/RD/RL/RM/RW, U, DM/DMM Models
|This section does not cite any references or sources. (June 2008)|
Mack started to produce the R, RW, and U models in 1966 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, the RW Superliner with a large, rectangular hood and grill in 1977, 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.
In the 1990s, the R, RW, 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 2006 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.
Also this model is serving in the Mexican Army as a Troop and Utility Truck in Configuration 6X6 OR 6X4
By 1916 Mack was producing 4 and 6 cylinder gasoline engines, in 2014 they continue to build their engines. Other builder’s engines were often optional, engines from Caterpillar, Cummins, Detroit Diesel, Hercules, Scania, and Waukesha have been used.
Mack started making diesels in 1938, in 1957 the END and turbocharged ENDT 673 diesel were introduced. This 672 cu in (11.0 L) I6 engine family was successful, and remained in production for over 30 years.
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 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.
Mack also produced railroad cars and locomotives between 1905 and 1930.
- MP engine series
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.
