Info
Hello, we are Sofia University Racing, the first EV team from Bulgaria. We are brand new team and this is our first year trying to build a car. And this is the result! The name of the car is chosen based on Bulgarian emergency hotline (also the number of the car) and it also shows how we did pretty much everything on this car.
