BMW E39 M5 Features Secret Volkswagen W10 Engine

A highly unusual BMW E39 M5, originally manufactured with a V8 engine, has undergone a significant powertrain transformation, now featuring a naturally aspirated Volkswagen W10 engine. This unique vehicle is scheduled to go to auction, presenting a rare opportunity for collectors and automotive enthusiasts. The W10 engine, a complex configuration typically found in Volkswagen Group vehicles, has been integrated into the E39 M5 chassis, a model renowned for its performance and driving dynamics during its production run from 1998 to 2003. The E39 M5 was factory-equipped with a 4.9-liter S62 V8 engine, producing 394 horsepower and 369 lb-ft of torque, paired with a Getrag Type D six-speed manual transmission. The swap to a Volkswagen W10 engine represents a substantial engineering undertaking, requiring extensive modifications to the engine bay, drivetrain, and potentially the vehicle's electronics and suspension systems to accommodate the different engine architecture and power delivery. The specific W10 engine used in this build is a naturally aspirated variant, distinguishing it from turbocharged versions that have appeared in other Volkswagen Group models. The presence of a six-speed manual gearbox further enhances the driver-focused nature of this custom build, aligning with the enthusiast appeal of the original M5. Adding to the intrigue of this particular vehicle is a documented connection to Ferdinand Piëch, the influential former chairman of Volkswagen AG and a pivotal figure in the automotive industry. Piëch was known for his engineering prowess and his ambition to push automotive boundaries, often through complex and innovative engine designs. The paper trail linking this modified M5 to Piëch suggests a potential personal interest or involvement in the project, further elevating its historical and collectible value. The auction of this one-of-a-kind BMW E39 M5 is expected to attract significant attention from those who appreciate bespoke automotive creations and the legacy of automotive engineering giants. The E39 M5 itself is considered a modern classic, celebrated for its blend of everyday usability and track-capable performance, making any modification to its core components a subject of considerable interest. The integration of a W10 engine, a configuration not found in any BMW production vehicle, transforms this M5 into a truly singular machine, representing a fusion of German engineering from two distinct automotive powerhouses. The auction details and the specific provenance of the Piëch connection will be crucial factors in determining the final sale price of this extraordinary automobile.
