Developed in Mauá, SP, the FADIM K2, the prototype of the most economical vehicle in Brazil, overcomes technical challenges and points to innovations for sustainable mobility in the country
The city of Mauá, São Paulo, was the stage for the development of one of the most efficient vehicles ever registered in Brazil. In 2009, a group of engineers and academics led by Leone MaurÃcio Fragassi presented the FADIM K2, a project that won the title of the most economical vehicle prototype in Brazil, achieving the impressive mark of 113,4 km per liter of gasoline. The development stood out not only for its reduced consumption, but also for its innovative approach aimed at sustainable mobility.
Origin and development of the project
The most economical vehicle prototype in Brazil, the FADIM K2, was born from an academic and business initiative that aimed to encourage the creation of highly efficient vehicles. The development of the model was supported by the company Projeto de Comunicação, in addition to the participation of engineering professors and students. The objective was to facilitate a university competition inspired by the Shell Eco-Marathon, one of the most renowned energy efficiency tests in the world.
The vehicle was tested at GM Brazil's proving ground in Indaiatuba (SP), where the prototype faced rigorous technical challenges. The team had to deal with budget constraints and optimize the car's aerodynamics to maximize fuel efficiency. According to Fragassi, the project required meticulous planning and creative solutions to overcome the limitations imposed by the competition's regulations.

Technical specifications and performance
The FADIM K2, recognized as the most economical vehicle prototype in Brazil, was designed to be lightweight and aerodynamic, with a structure composed of aluminum, carbon steel, fiberglass, carbon fiber and acrylic. Its 70cc single-cylinder, air-cooled gasoline engine was optimized to reduce consumption to the minimum necessary.
During testing, the vehicle maintained an average speed 35 km/h, but its maximum recorded speed was 70 km/h. Consumption was measured precisely: each team received 200 ml of gasoline, and the vehicle traveled a 10 km route on a level, paved track. The remaining fuel was weighed to calculate actual consumption.
Impact and innovations in sustainable mobility
The success of Brazil's most economical vehicle prototype has spurred new research and investment in sustainable mobility. After the project, Leone Fragassi dedicated himself to the study and development of Velomobiles, highly efficient individual vehicles widely used in Europe. The engineer believes that this type of technology has the potential to revolutionize urban transportation in Brazil.
Fragassi highlights that the evolution of materials and technologies, such as nanotechnology and carbon fibers, is transforming the automotive sector. According to him, Velomobiles represent a viable solution to reduce the environmental impact of urban travel, following models already adopted in countries such as the Netherlands, France and Denmark.
