Volkswagen Group MQB platform

The Volkswagen Group MQB platform is the company's strategy for shared modular construction of its transverse, front-engined, front-wheel drive (optional four-wheel drive) automobiles. Volkswagen spent roughly $60bn developing this new platform and cars built upon it. The platform underpins a wide range of cars from the supermini class to the full size SUV class. MQB allows Volkswagen to assemble any of its cars based on this platform across all of its MQB ready factories. This allows the Volkswagen group flexibility to shift production as needed between its different factories. Beginning in 2012, Volkswagen Group marketed the strategy under the code name MQB, which stands for Modularer Querbaukasten, translating from German to "Modular Transversal Toolkit" or "Modular Transverse Matrix". MQB is one strategy within VW's overall MB (Modularer Baukasten or modular matrix) program which also includes the similar MLB strategy for vehicles with longitudinal engine orientation.

MQB is not a platform as such, but, rather, a system for introducing rationality to different platforms that have transverse engines, regardless of model, vehicle size or brand. Thus MQB uses a core "matrix" of components across a wide variety of platforms — for example, sharing a common engine-mounting core for all drivetrains (e.g., gasoline, diesel, natural gas, hybrid and purely electric). As well as reducing weight, the concept allows different models to be manufactured at the same plant, further saving cost.

Ulrich Hackenberg, chief of Volkswagen’s Research and Development (Head of Audi Development until 2015), called MB a "strategic weapon."

British magazine Car said "the idea heralds a return to basic principles of mass production in an industry where over the last 100 years, complexity has spiralled out of control. By creating a standardised, interchangeable set of parts from which to build a variety of cars, (the company) plans to cut the time taken to build a car by 30%."

The car weblog Jalopnik said "The biggest feature is the uniform position of all motors and transmissions" and that "by fitting all motors into the same place (the company) hope(s) to cut down on engineering costs and weight/complexity when porting the car over to other models." Around 60% of the development costs occur between gas pedal and front wheels, including the engine.
