The team was founded in 2007 at TU Budapest with the purpose of participating in the international Formula Student series. We are proud to be the pioneers of Hungary’s FS teams. Since 2011 we have been the first team in Hungary to race in the electric category and the only one building driverless cars. We are making a comeback to FSG after 2023 with a completely redesigned vehicle aiming for the podium once again. Our motto for the season: Keep gambling.

The team was founded in 2007 at TU Budapest with the purpose of participating in the international Formula Student series. We are proud to be the pioneers of Hungary’s FS teams. Since 2011 we have been the first and only team in Hungary to race in the more environmentally friendly electric category, being the leaders in constructing driverless FS cars as well. Last year we had one of our strongest season, finishing on the podium in FSG, with significant improvements to our driverless system.

BME Formula Racing Team is the pioneer of the hungarian FS teams. At the beginning, we made cars powered by gasoline, but in 2011 we were the first team in the country to switch to the more innovative electric category. The successful 2021 season - where we achieved our best overall score so far - built a great foundation for this year. This year we built an EV/DV car to compete fully under the FSG ruleset, to be able to race against the very bests and to collect throphies instead of cones.

The BME Formula Racing Team from TU Budapest was established in 2007 by several enthusiastic master and postgraduate students. This season though, the team operates with 95 active members. In 2014 the FRT enters the competition with its 9th car, the FREC-004, which is also the 4th electric racecar built by the team. BME FRT’s goal for this season is to be a mentionable competitor against the best teams of the world at FS Germany and aims to reach the top 10 in the World Ranking.
