KARACHI:

In the corridors of Pakistan Navy Engineering College at National University of Sciences and Technology (PNEC-NUST), a spark of innovation ignited in 2009. A group of passionate students, fueled by the thrill of competition and the desire to make a difference, came together with a shared vision - to create something that would change the game. As Sadus Rizwan, a founding member of Team Envision, recounts, "We were driven by the opportunity to participate in the Shell Eco-Marathon for the very first time." The idea was simple yet ambitious, "to design and build an energy-efficient vehicle that could compete on an international stage."

In a small lab within the university, the team's journey began, marked by countless hours of brainstorming, designing, and building. Their initial goal was to create a vehicle that would not only represent Pakistan globally but also showcase the country's potential for innovation. And so, Team Envision was born. Over the next 15 years, the team would go on to build 17 cars, each one a testament to their growing expertise and innovative spirit.

Through their journey, Team Envision consistently represented Pakistan in global competitions, earning multiple awards for their innovative designs.
