Diesel Audi Car Wins Le Mans for First Time, Beating Gasoline.
.
June 18 (Bloomberg) -- A diesel engine car won the Le Mans 24-hour race in France for the first time as advances in engine and fuel technology allowed German carmaker Audi to overcome rivals using gasoline engines.
.
The car, driven by Germans Frank Biela and Marco Werner, and Italy's Emanuele Pirro, completed a record 380 laps at speeds over 200 kilometers an hour (125 miles an hour). The second-place car was four laps adrift.
.
The R10 turbo diesel injection, 12-cylinder engine was developed by Audi AG, the luxury and sports car division of Volkswagen AG, Europe's largest carmaker, and ran on a fuel made by Royal Dutch Shell Plc that is cleaner and more efficient than regular diesel.
