Like many other of his peers, Christian Vietoris began his racing career with karts, and was a force to reckon with in the field of kart racing right from a young age. He bagged second place in a championship, at the age of 11, in the German ADAC Kart championships, in the Bambini A category.
Clearly one of the stronger drivers in the A1 Team Germany, Vietoris has maintained a winning streak so far in his short career. Just 19 years old, Vietoris soon bagged the championship title in the Bambini A category in 2001, and along the way also bagged the West German ADAC Kart championship, and was in 1st place in the ADAC Kart championships in the Central Region.
In 2002, Vietoris once again clinched every single title that he had won the previous year, by bagging the titles in all the three categories. In 2003, Vietoris became eligible to participate in the Junior Kart championship and did not fail to impress. The very same year he won the German ADAC Junior Kart championships, and he also participated in the West German ADAC Kart championship, where he only came in second, which came as a big shock to the talented youngster.
In 2004, Vietoris could not keep up his top form, and only participated in the West German ADAC Kart championships, in which also he could only manage a second place finish. The next year he moved onto Formula BMW ADAC championships, and this jump up was too sudden for the young driver, and he had a disappointing season. He finished 17th in the series and was ranked 9th amongst the rookies participating that year.
Vietoris returned in 2006, and took the series by storm, he went on to win the Formula BMW Germany series, with a total of 9 race wins under his belt. After his successful stint with the Formula BMW series, Vietoris went on to race with A1 Team Germany, for whom he raced in the Mexico round. His qualifying session was quite impressive and Vietoris managed a second place in the starting grid. Even though he managed only a 21st place in the Sprint race, Vietoris came in 9th in the main race, once again proving his immense talent.
