In 2010, the municipality decided to found a new company called Otobüs A.Ş. (Bus Inc.) in order to more quickly replace old vehicles. Otobüs A.Ş. had a fleet of 544 vehicles as of December 2012. The vehicles are fully low floor and certified to Euro 5 standards. In 2014, IETT carried 1.31 billion ticketed passengers, a record for a Turkish transport system. İETT is currently trialling outsourcing the drivers and maintenance into private bus company Akkurtlar. Outsourced drivers can be distinguished by their uniforms.
