Petr Mráz is a rally driver from Nosálov in the Central Bohemian Region of the Czech Republic. He first competed in 2001 at the Rallysprint Blovice. In 2008 he switched to a Škoda Fabia A5 (ex Fabia Cup), and in the 2009 season he took part in the Czech Sprint Rally Championship. His best result is 3rd place in class A5 at Rally Krkonoše 2009.
The 2009 season showed how demanding motorsport is. Three of the four rallies ended with technical problems — the engine at Lužické hory and the electronic control unit at Kopná and Třebíč. After a complete overhaul of the car, Krkonoše brought a finished rally and a class podium, even though the crew was delayed by a puncture and a burst power-steering hose.
