The Volkswagen Jetta (A7) is a compact car, the seventh generation of the Volkswagen Jetta and the successor to the Volkswagen Jetta (A6). The 2018 Jetta debuted at the 2018 North American International Auto Show in Detroit, Michigan, on 14 January 2018, after Volkswagen released an exterior design sketch in December 2017. The Jetta is based on Volkswagen's MQB platform, which underpins other Volkswagen vehicles including the Volkswagen Golf and the Volkswagen Atlas. The A7 Jetta marked the discontinuation of the nameplate in the European market and right-hand-drive markets.

The Volkswagen Group MQB platform is the company's strategy for shared modular design construction of its transverse, front-engine, front-wheel-drive layout automobiles. It was first introduced in the Volkswagen Golf Mk7 in late 2012. Volkswagen spent roughly $8bn developing this new platform and the cars employing it. The platform underpins a wide range of cars from the supermini class to the mid 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 program which also includes the similar MLB strategy for vehicles with longitudinal engine orientation.
