Audi and Lamborghini Finalize Production of Hand-Built 5.2-Liter V10

In the Hungarian town of Győr, Audi finalized the production run of its 5.2-liter naturally aspirated V10 engine, an architectural marvel that required six hours of manual labor per unit to assemble. This process involved the precise integration of approximately 250 individual parts for every engine, a level of detail that allowed the facility to produce roughly 19 units per shift.

The 5.2-liter V10 served as a central power source for both the Audi R8 and the Lamborghini Huracan. Despite sharing roughly 75% of its internal components, Audi maintained distinct characteristics for the engine in each vehicle, positioning it as an exotic powerhouse for Lamborghini and a more restrained powerplant for Audi.

High Engine Speeds Strain Internal Components

The engine’s design was significantly more intricate than typical mass-produced powerplants, featuring 40 valves and four camshafts. Its naturally aspirated operation relied on high engine speeds to generate power, reaching a redline of 8,700 rpm. At this peak, the engine’s internal components—including the pistons, connecting rods, and crankshaft—were subjected to extreme strain, with pistons traveling at approximately 26.9 meters per second. The engine utilized a 3.65-inch piston stroke and a 3.33-inch bore to achieve these high revolutions, supported by specialized lubrication and cooling systems designed to handle the thermal load. Unlike turbocharged alternatives, this powerplant provided linear acceleration and immediate throttle response without lag, utilizing a distinct firing interval of 54 and 90 degrees.

While road-going versions underwent standard bench testing, racing-spec variants were subjected to more rigorous evaluations to ensure reliability under maximum performance conditions.

A Legacy of Joint Production

• The V10 originated from a 5.0-liter mill first introduced in the 2003 Lamborghini Gallardo.
• This engine marked the first collaborative project between Audi and Lamborghini following Volkswagen’s 1998 acquisition of the Italian brand.
• The 5.2-liter version entered the market in 2006, eventually reaching a factory-rated peak of approximately 630 horsepower.

While the production of this engine has now concluded, the specific details regarding the exact number of units produced throughout its entire lifecycle remain unaddressed by current records.
