Mack Trucks, Inc. is an American truck-manufacturing company and a former manufacturer of buses and trolley buses. A wholly owned subsidiary of Renault Véhicules Industriels since 1990, Mack Trucks is currently a subsidiary of AB Volvo. The company's headquarters are located in Greensboro, North Carolina. On September 3, 2009, a three-month transition from its headquarters in Allentown, Pennsylvania, to Greensboro was completed.
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. The company's distinctive logo, a chrome-plated (sometimes gold-plated) bulldog, 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 have been sold in 45 countries. The Macungie, Pennsylvania, manufacturing plant, located close to its abandoned 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.
On August 14, 2008, Mack Trucks announced a major restructuring plan that includes:
- 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 produced in Macungie

They later had 1-piece hoods, the RD had a new hood, and the DM the U hood. In the late 1980s, 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.
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 first available in the 1968 model year trucks. This was an industry-changing event. The Maxidyne allowed.
The company's trademark is the 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.
The Mack R Model was a Class 8 heavy-duty truck first introduced in 1966, by Mack Trucks, to replace the very successful Mack B Model. Its production ran for 40 years until the RD model was discontinued in 2002 and the RB and DM models were discontinued in 2005. The first R models introduced were powered by Mack Thermodyne diesel and gasoline engines. In 1973 the R cab was given a makeover to include a deeper rear wall for more room and a new dashboard design.
The Mack B Model was a heavy truck produced by Mack Trucks between 1953 and 1966. It is perhaps the best known classic Mack truck and many still survive to this day in both restored and unrestored conditions. Some owners still use them daily for both business and leisure. They were available as fire trucks, school buses and in a variety of truck configurations. The B model was replaced by the R Model.

The Mack F series was the third generation of cabover trucks from Mack Trucks. Its production began in 1962 and ended in 1981. It was produced primarily as a set-forward axle truck but a setback axle version was shipped overseas (from the USA). The cab came in a 50 inch (1371.6mm) day cab (no sleeper). Sleeper models included a 72 inch (1828.8mm), 80 inch (2032mm) and later a "bustle back" was added that lengthened the sleeper to 86 inches (2184.4mm).
- The Mack Super-Liner is a class 8 heavy-duty truck that was introduced by Mack Trucks in 1977, to replace the Mack RW (R-Western) model. Its production lasted for fifteen years until it was discontinued in 1993. The model designation is RW. Mack Trucks Australia still manufactures the Super-Liner as a lighter-duty version of the Mack Titan.
- In 1988, Mack Trucks Australia made 16 special edition SuperLiner II Bicentennials with the E9-500 V8, Mack 12 speed triple countershaft transmission, Mack front and rear axles, long taper-leaf springs on front and camelback on the rear, Spicer 1810 HD driveshafts and 5842mm (230 inch) wheelbase. The special limited edition models were named after people influential to Australian history, including James Cook, Captain Bligh, Ludwig Leichhardt, Governor Phillip, Ned Kelly, Kingsford Smith, and John Flynn. One remaining example is operated by Eagle Towing Service, of Ringwood Victoria and has since been converted to a heavy towing salvage truck. 
- This truck is also the inspiration of the character "Mack" in the Movie "Cars".
The Mack Titan is a heavy duty truck produced by Mack Trucks. There are two different variants of the Titan, one for the Australian market, that was first introduced in 1995 aimed at the heavy road train operators of Australia, and a 2008 model that was introduced in North America. The Titan can haul loads up to 200 tonnes GCM and comes with many heavy duty options that are not usually found on highway trucks.
- A raised cab and taller hood allows for larger radiators to cool the engine more quickly in the hot Australian climates.
- Heavy duty double and triple frame rails handle the high loads and stress of driving on unpaved dirt roads.
- Rear axles offered include tri-drive options and planetary hub reduction axles from Renault Trucks.
- Air brake system has high flow air compressor and large air tanks to provide air for 2 or more trailers and the air starter (if fitted).
- Integrated vertical air intake snorkels keep dust and dirt out of the filters prolonging their life.
- High power engines from Cummins (ISX & Signature) and Caterpillar (C-16) provide the necessary power. Up until 2000/2001, the Mack 16.4 litre E9 V8 was offered at 455 kW (610 hp) and 2780 Nm (2050 ft•lbf) of torque.
- The Mack 18 speed transmission is standard with an Eaton 18 speed option. Eaton two and four speed auxiliary transmissions are also available to provide extra gears and an optional Power Tower.
The first Mack, an AC model, arrived in Australia in 1919 and was used for bulk haulage by the Vacuum Oil Company in Sydney. The second arrived six weeks later. The ACs, although greatly admired, did not have much impact on transport trends and it would be another 30 years before Mack would change the course of heavy transport in Australia. However, Australia’s first purpose-built engine driven furniture removals van was also a Mack. The 1924 AB model was put into service in 1928 by Thos Mills and Sons of Rose Bay and having completed 30 years of continual service and travelled a million miles, it was finally retired in 1958.
The arrival of the American military in early 1942 brought the heavier trucks, the NR 6x4 Macks and the Diamond T tank transporters as well as the US Army truck of the day, a standard GMC 2l,2 powered by powerful GMC 270 cubic inch engines.
It was the arrival of the legendary B Model Mack that would finally establish the Mack name as a leader in reliability and good value for money in the toughest conditions Australia had to offer. The B Model was first released in 1953 and by the early 1960s it reigned supreme in the outback of Australia. They took on the bogs and the jump-ups with ease and survived the many hardships of the outback that the English models found difficult. They brought new dimensions of speed, strength, comfort and reliability to the industry.
In the Northern Territory roadtrain operators were able to double their speed from 27kph to around 55 kph and in the more populated areas in the southern and eastern states the B model could pick up 60 tonnes of freight and cross the nation in quicker time than ever before. The B Model also found success in heavier off-road applications such as livestock and ore haulage. The B6 1 was the backbone of Brambles coal haulage operation and today the company still operate a few on their low loaders. When the B Model went out of production in 1966, nearly 130,000 had been built. The classic B6 1 Model revolutionised the heavy transport sector in Australia and is regarded as one of the most revered of all heavy transport trucks in Australia, being remembered as a life-style, not a truck, and a rugged and tough lifestyle at that.
In 1966 Mack released its revolutionary Maxidyne engine and Maxitorque transmission. Instead of 10 or 15-speed gearboxes the Mack now only required five gears. The R Series and the later Superliners are also legends in the world of trucking. There is something about the squared up macho look of a Mack truck that other manufacturers have failed to find. While the new CLR 525hp models have been well accepted for their performance and reliability, many of the old school are sad to see the shape of the mighty Mack truck change. Mack, however, is one company that prides itself on its ability to respond to the changing needs of the road transport industry and the 1 990s have seen the release of many new Macks, including the classic CHR Select B-double primemover, the Elite Series and the long-wheelbased Mack Manager.
The 1995 release of the new Mack Super-liner Titan is likely to see Mack regain its position as leader of the pack in the heavy truck range. Fully Australian-designed and purpose-built to handle Australia’s harsh operating environment, the Super-liner Titan is the toughest and most powerful Mack yet. Fitted with the Mack E9 525 V8 engine and specced for up to 200 tonne GCM, the Titan is ready, willing and able to take on any application. For Mack loyalists around the country, it is the return of the traditional Mack Superliner strength, reliability and good looks that will return them to the fold.
Today, the Mack organisation is so large it churns out around 30,000 trucks every year, and it continues to hold the lion’s share of the Australian market when it comes to heavy duty and off-road applications in Australia. Usually a Mack truck is just that. It is Mack from one end to the other, including, engine gear box, diffs and suspension. Operators today can order a Mack with a different engine, usually a Cummins or Caterpillar. It is easy to tell if the Mack is a pedigree by the colour of the dog on the grill.
huge 6x4 NR Macks and determined looking EH Macks found their niche in off-road applications such as hauling timber, cattle and heavy machinery in the more remote areas of Australia that were not so staunchly controlled by government regulation and where the rail had not yet reached.
Bell Bros used Mack trucks and a variety of smaller operators found success in operating the big British trucks of the day, the Leylands.
