Volkswagen's MLB is derived from the German abbreviation 'Modularer Längsbaukasten,' which means Longitudinal Engine Standardization Platform. MLB, MQB, and MEB all belong to Volkswagen's modular systems. MLB helps achieve a balanced front-to-rear weight distribution in vehicles, enhancing driving stability and comfort. Below is additional information: Vehicle Module: The most significant feature of vehicle modules is their high compatibility. Whether it's independent suspension or beam axle, long or short wheelbase, A-segment or B-segment cars, they can all use the same module. The platform concept was first proposed and implemented by Volkswagen. Advantages: With modularization, Volkswagen's manufacturing costs are reduced. The commonality of parts across platforms also significantly lowers maintenance costs for car owners. Additionally, the price of commercial car insurance decreases accordingly. Therefore, modularization offers more benefits than drawbacks compared to traditional platform approaches.

I've been repairing cars for nearly 20 years and always hear colleagues talk about the MLB platform. It's essentially a high-end vehicle chassis architecture developed by the Volkswagen Group in Germany, known as the longitudinal engine platform at Audi. The most distinctive feature of this system is its longitudinally mounted engine with a driveshaft running through the center, enabling more balanced weight distribution between the front and rear axles. Nowadays, almost all Audi models above the A4 use this foundation, and even the Porsche Cayenne and Bentley Bentayga adopt it. When I last serviced a Lamborghini Urus and opened it up, I found it was actually a heavily modified version of the MLB platform too.

Friends who are into car modifications often talk about the MLB Evo platform, which is considered an upgraded version of MLB. Audi models like the A6L and Q7 built on this platform offer a noticeably stable and refined chassis feel. The key lies in the longitudinal layout, which frees up more space for complex suspension systems—such as the front five-link and rear trapezoidal arm setup—resulting in a smooth ride even over speed bumps. Last time I helped my cousin adjust the coilovers on his Q5, I noticed the high interchangeability of chassis components, thanks to its modular platform design.

The Touareg we bought last year is indeed built on the MLB platform, and the salesperson repeatedly emphasized it as a 'longitudinal engine luxury platform' during the purchase. In actual driving, it does handle turns more nimbly compared to transverse-platform vehicles, and the longitudinal arrangement of the engine and transmission prevents the front end from feeling too heavy. However, it's worth noting that repairs on this platform require removing more components—last time, the labor cost for replacing spark plugs was twice as expensive as my neighbor's transverse-engine car.
