Alfa Romeo has competed successfully in Grand Prix motor racing, Formula One, sportscar racing, touring car racing, and rallies. It has competed both as a constructor and an engine supplier, via works entries (usually under the name Alfa Corse or Autodelta), and private entries. The first racing car was made in 1913, three years after the foundation of the company, and Alfa Romeo won the inaugural world championship for Grand Prix cars in 1925.
