In the internationally renowned competition entitled "Engine of the Year Awards", engines from the Stuttgart region won in four out of twelve categories. Three awards went to Mercedes-Benz and AMG and one to Porsche. The engine awards are bestowed by a specialist British publishing company and are among the most important in the automotive industry. One of the most environment-friendly engines in the competition was the new four-cylinder diesel engine from Mercedes-Benz, which won in category 2 up to 2.5 litres.
