R10

R10 is a designation used in various domains to identify models, products, or codes. The most widely recognized reference is the Audi R10 TDI, a diesel-powered Le Mans prototype developed by Audi AG. The car debuted in endurance racing in 2006 and went on to win the 24 Hours of Le Mans in 2007 and 2008, contributing to Audi's dominance in the event during that era. The R10 TDI featured a mid-mounted turbocharged diesel V12 engine and advanced aerodynamics for LMP1 competition, helping to establish diesel-powered prototypes as a top category in sports car racing.

Beyond motorsport, R10 has been used as a general designation in other products and systems, including model numbers, part identifiers, or route labels, depending on the region and industry. Because it is a short alphanumeric code, its exact referent is context-dependent. In documentation and cataloging, R10 can therefore indicate different items or versions, and clarity typically requires additional context such as the manufacturer, sector, or accompanying specifications.
