Mack had 13.3% market share in 1999, and now 10 years after Volvo bought them, Mack has 7.5%. What happened here is simple - Volvo bought another competitor, then they "integrated" them with their poor data management systems and then they "synergized" their product for part cost savings on all models in purchasing of parts, this included commonizing many parts from the volvo models into the macks, the frames are now identical (with the exception of the LEU/MRU refuse models) as well as the engines, and many of the parts such as steps, deck plates, fuel tanks, etc. After that the final blow came which was "consolidation" of the Mack World Headquarters putting hundreds of people out of work, a very small percentage did re-locate to North Carolina where they have a far inferior presence and design validation facility vs Allentown PA. All the while more parts for the Mack are now made outside the USA than you can imagine but I guess thats the way it is for all OEMs nowadays since the Govt sold our jobs down the river with NAFTA and free trade with china etc., I.T. Support for volvo/mack is done from their site in BRAZIL and INDIA as well as many engineering fuctions with the exception of Customer Engineering based in Allentown PA (for now). However, on a positive note MACK is the ONLY CLASS 8 OEM still assembling trucks in the USA and let me tell you their Macungie Assembly plant is THE BEST truck plant in the world. They do it better, faster, and have very high quality people out there. With Volvo though, there is a pattern here,,, first they dismantled WHITE trucks, then they went thru AUTOCAR and what you see today as a VHD model is really an autocar/volvo combined truck, then they went after the big gun for construction market share in north america --- MACK.... who is next? very sad state of affairs in all this.
