MQB

MQB stands for Modularer Querbaukasten, a modular platform strategy developed by the Volkswagen Group to standardize the architecture of front-engine, front-wheel-drive or all-wheel-drive vehicles. Introduced in the early 2010s, MQB enables a wide range of models to share core components and production processes while varying wheelbase, track, and bodystyle as needed.

Under MQB, key modules such as engine mounts, transmissions, front and rear axles, electrical systems, cabins, and control electronics are designed to be interchangeable across models and brands within the group (VW, Audi, SEAT, Skoda). This allows developers to mix and match powertrains with minimal redesign, reducing development time and manufacturing costs while preserving performance and safety standards.

Powertrain options include turbocharged petrol and diesel engines, along with hybrid variants and, in some cases, plug-in hybrids. The platform also accommodates electrification strategies, with space for batteries and e-motors as needed. The system supports several body types and wheelbases by adjusting subframes and component placement, enabling compact cars to mid-size sedans using common parts.

MQB has been widely adopted by brands under the VW Group umbrella, including the Golf, A3, Leon, Octavia, and many others. It is part of a broader modular platform strategy that also includes longitudinal platforms such as MLB and MEB for electrified vehicles.
