Clemson University and BMW Unveil Solar-Powered Prototype with 31 Extra Miles of Daily Range

en.Wedoany.com Reported - Clemson University and BMW have jointly unveiled the Deep Orange 17 electric vehicle prototype. This solar-integrated, energy-positive vehicle is designed to generate more energy than a typical urban commute consumes, combining solar technology, lightweight engineering, and intelligent vehicle controls to prove that energy-positive mobility is possible.

Deep Orange 17 is the latest concept vehicle from Clemson University's Deep Orange program, in which automotive engineering graduate students work alongside industry partners to design, engineer, and manufacture functional prototypes. In fall 2024, BMW challenged the students involved in the project: could a vehicle generate more energy than it consumes during daily driving?

Rather than optimizing solely for standardized driving cycles, the team started from real-world usage patterns. Since passenger vehicles spend most of their time parked, collecting solar energy throughout the day became possible; the students also designed the vehicle to capture solar energy while in motion, making sunlight a continuous energy source.

At the core of the vehicle is a fully integrated solar system—solar power is not an auxiliary feature but a central part of the vehicle's propulsion strategy. More than 1,700 photovoltaic cells are integrated directly into the exterior body surfaces, allowing the vehicle to collect energy both when parked and when driving. The solar panels were developed in collaboration with the Fraunhofer Institute for Solar Energy Systems (ISE), and they continue to generate power even when partially shaded, with an outer protective film that achieves its distinctive color through advanced laser manufacturing processes.

To evaluate real-world performance, the students simulated environmental conditions and solar availability in Greenville, South Carolina; Frankfurt, Germany; Madrid, Spain; and Mumbai, India. Assuming a daily commute of 12 miles (20 km), the vehicle generates sufficient surplus solar energy at all four locations, providing an average of 31 miles (50 km) of additional range.

Energy positivity cannot be achieved with solar panels alone. Deep Orange 17 weighs 1,212 pounds (550 kg)—roughly one-quarter the weight of many similarly sized production vehicles. The multi-material chassis combines structural steel for occupant safety, aluminum components, carbon fiber structural elements, and 3D-printed metal joints, reducing mass while maintaining strength. The exterior design draws inspiration from the aerodynamic properties of the boxfish, with a streamlined body that reduces drag while preserving interior volume. Regenerative braking, intelligent torque distribution, and optimized drive control systems work together to maximize energy recovery and enhance overall performance.

BMW challenged the team to prove that efficiency does not have to come at the expense of emotional design. The result is a two-door coupe named Luminetta, a name that reflects both its solar-powered capability and its retro-modern design heritage. The interior features a custom human-machine interface providing real-time vehicle telemetry, with support for Apple CarPlay and Android Auto, delivering a connected driving experience that balances innovation and practicality.

Stephan Augustin, BMW's Project Manager for Research and New Technologies, said this is a project they have wanted to do for years, and that the students overcame significant technical challenges and constraints over the past two years to make an energy-positive vehicle a reality. Harsh Manghnani, Deep Orange team member and solar integration lead, said the project not only produced a functioning energy-positive prototype but also demonstrated how vehicles can achieve greater energy independence through solar integration.

The Deep Orange project also embodies Clemson University's experiential engineering education model. Students complete market research, customer needs definition, concept development, major systems engineering design, component manufacturing, and performance validation, working side-by-side with industry engineers and managing real-world budgets, schedules, and technical constraints. The 16 students who participated in developing Deep Orange 17 will graduate on August 7 with a Master of Science in Automotive Engineering. Anshul Karn, Deep Orange Project Manager, noted that master's students rarely have the opportunity to experience the complete prototype development process, and few programs allow students to start from a vision, go through the entire development process, and ultimately deliver a fully functional prototype—an experience that makes Deep Orange unique. Dr. Greg Mocko, Program Director, believes that students graduate not only with a diploma but also with the growth they have experienced as engineers, as individuals, and as a team over the past two years.

Research on the prototype will continue at Clemson University International Center for Automotive Research (CU-ICAR) in Greenville, South Carolina, serving as a platform for continued innovation in sustainable mobility. Deep Orange 17 is also scheduled to be exhibited at the Consumer Electronics Show (CES) in Las Vegas in 2027.
