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.
