The Volkswagen Group MQB (Modularer Querbaukasten) platform represents a paradigm shift in automotive manufacturing, offering unparalleled flexibility and efficiency. This innovative platform serves as the foundation for a vast range of vehicles across the Volkswagen Group’s diverse brand portfolio, from Volkswagen to Audi, Skoda, and SEAT. The MQB platform is engineered to accommodate a wide array of vehicle types and sizes, demonstrating its adaptability to market demands and customer preferences. Key parameters such as wheelbase, track width, and seating configurations can be customized, allowing each brand to maintain its unique identity while leveraging the shared benefits of the platform.
One of the core achievements of the MQB platform is significant weight reduction across vehicle models. By utilizing high-strength and ultra-high-strength steels in varying thicknesses for body components, vehicles built on the MQB platform are notably lighter than their predecessors. For instance, the introduction of MQB resulted in an average weight reduction of approximately 50 kilograms, with some models like the Golf VII experiencing reductions of up to 100 kilograms depending on specifications. This focus on lightweight construction contributes to improved fuel efficiency and enhanced vehicle dynamics.
Engine standardization is another cornerstone of the MQB platform’s design. Engines are mounted in a standardized transverse position, tilted rearwards by 12 degrees, with the intake side positioned at the front and the exhaust at the back. This standardized installation approach extends to both petrol (TSI) and diesel (TDI) engines, as well as alternative powertrains. For the TSI engines within the EA 211 series, which were developed alongside the MQB, engineers implemented a 180-degree rotation of the cylinder heads compared to the previous EA 111 engine series to align with the new platform standard.
The MQB platform’s forward-thinking design inherently supports a diverse range of powertrains. From its inception, the platform was conceived to accommodate petrol (TSI), diesel (TDI), and compressed natural gas (CNG) engines, as well as mild hybrid and plug-in hybrid systems. This versatility was clearly demonstrated with the Golf VII, which was offered as a fully electric e-Golf model from 2013 to 2020. Currently, MQB-based vehicles within the Volkswagen Group offer a power spectrum ranging from 48 kW (66 PS) to a robust 294 kW (400 PS), catering to a wide range of performance requirements.
Furthermore, the MQB platform has enabled a significant reduction in the number of component variants. By standardizing interfaces for power transmission in the new petrol and diesel engine families (EA 211 and EA 288 respectively), the Volkswagen Group streamlined compatibility with gearboxes and drive shafts. This standardization initiative led to an almost 50% decrease in engine and gearbox variants. The impact of standardization is even more pronounced in components like heater and air conditioning units, where the number of different versions plummeted from 102 to just 28.
The adoption of the MQB platform has revolutionized production efficiency within the Volkswagen Group. Its inherent flexibility allows Volkswagen and its brands to rapidly develop new models and variants. The platform has undergone continuous evolution and refinement over the years, with the current Golf representing the latest iteration. The standardized nature of MQB-based vehicles facilitates efficient manufacturing across the Group’s global production network. Model changeovers have also become significantly more streamlined; for example, when the Volkswagen plant in Wolfsburg transitioned to producing the new Golf in 2019, approximately 80% of existing body shop installations could still be utilized. The MQB platform’s adaptability extends to enabling the production of vehicles with varying wheelbases and track widths, as well as models from different brands, all on the same production line, showcasing its remarkable versatility and contributing to economies of scale.
