Team Description

Pravega is the Sanskrit word for acceleration. Pravega Racing is a team of engineers from Vellore Institute of Technology, Vellore and we seek to enhance the learning experience of the students at the university through implementation of engineering fundamentals within the context of building a formula style Racecar. We strive to achieve this by focusing on world class engineering practices, institutionalising innovation and by creating a culture of open communication for cross pollination of ideas, while maintaining highest standards of integrity and honesty.

Pravega is the Sanskrit word for acceleration. The team was conceived in the year 2009, everything that followed has been an amalgamation of hard work, perseverance and eventually - glory. Year after year, the team has maintained a consistent growth rate which led to it being crowned the best team in India in the year 2017. PRV-23 is the 12th edition of our Formula Style Race-car which was designed and manufactured with an objective to achieve improved reliability while keeping it light.

Pravega Racing is one of the fastest growing formula student team in India.The word 'Pravega' originates from sanskrit meaning 'ACCELERATION'. With a hard working and dedicated team this year they have reduced their car weight by using smart engineering materials. They have optimized the dynamic performance of the car by tuning power train and vehicle dynamic using data acquisition.They have also used various efficient manufacturing to reduce lead time and improve performance.

Engineering Design Priorities:

Four years ago a group of students decided to lend their theoretical knowledge some leverage, by forming Pravega Racing which means "High Speed" in sanskrit and it augurs well with the team's rapid growth in the recent past as they were the 2nd fastest growing team in the world after FSAEI 2013 results. This year they have taken a step forward by integrating DAQ into our testing phase, using carbon fiber extensively to reduce weight, and pneumatic shifting to reduce shift time substantially.
