The Volkswagen Group MSB platform (Modularer Standardantriebsbaukasten, modular standard drivetrain matrix) is the company's strategy for shared modular design construction of its longitudinal, front-engine, rear-wheel-drive layout (optional front-engine, four-wheel-drive layout) automobiles. It was developed by Porsche for vehicles with longitudinally mounted engines and gearboxes and four-wheel or rear-wheel drive. It has been in use since 2016 and was introduced with the second generation Porsche Panamera.
The MSB architecture replaces the D1 platform and that used on the first generation 970 Porsche Panamera (G1).
