RAFI KADIR

STANISLAV VLADIMIROV

He was born on 26 April 1989 in the town of Provadia.

He started his non-professional racing career at the age of 17, and in his very first start he recorded a win in his category and a second place in the general classification.

After coming of age, he participated in numerous amateur competitions with VAZ 2101, winning more than 30 awards.

Luckily for him, Boyan Bezus and one of the legends of Bulgarian motor sport - Todor Slavov, noticed his talent. The two professional racers gave him a hand to make his first start in the national championship in mountain climbing, providing free of charge racing tires and a fully equipped car - Opel Astra, the same that Stanislav drives to this day.

The debut was in the summer of 2011, in Targovishte, where at that time a round of the mountain climbing championship was held. Stanislav won the second place in his class (X3), defeated by Lyuben Kamenov - one of the best Bulgarian competitors in this championship.

In 2013. Stanislav purchased the racing Opel Astra from B. Bezus and began his preparation for the national rally sprint championship.

In the first race of this type - "Rally Sprint Varna" (2014), due to a technical failure the car left the track and hit a curb. The damage is serious and does not allow the crew to continue with their participation. At the next edition, held in the town of Varna. Stanislav finished first in his class and third in the general classification for non-homologated cars.

One year later, again in the town of. Varna, debuted in the rally championship. The "royal" discipline of motor racing was an expected step in his development as a driver. The crew finished the stages near the sea capital in second place in the RC 3 class, being overtaken by the unbeatable Todor Slavov, who then won the general classification.

In the next round of the championship - "Rally Tvarditsa-Elena", the crew again reached the second place.

The race, unfortunately for all motorsport fans, was marked by a serious accident, in which Todor Slavov died.

In the fourth round - "Rally of the Old Capitals", events did not go in favour of the crew. In heavy rain, due to pilot error, the car fell into aquaplaning at a speed of 174 km/h. Fortunately everyone was unhurt and the material damage was minor.

The 2016 season has been extremely successful for Stanislav. He won the championship title in the RC 3 class and finished the year in second position in the 2WD class. It was also the competitor's only full rally season.

Episodic appearances in rally, rally sprint and mountain climbing competitions followed, crowned with more victories. Stanislav made two strong competitions in the 2019 season - Rally Bulgaria and Rally MONBAT Sliven, in which he won first and second place in the RC 3 class, respectively.

Due to lack of financial resources and the inability to complete a "full calendar", plans for the 2021 season include a move to the non-homologated autobike group - E1. This category allows for an increase in the power of the car as well as a drastic reduction in its weight. For this purpose, hard work is boiling on the familiar to all car fans - Opel Astra.

The decision to do so was also made taking into account Stanislav Vladimirov's desire to participate in the races solely for the adrenaline and pure pleasure they give him.
