Clemson University participates in the design of the $2 million Natalia SLS 2.

The designs they produced are excellent. We were already impressed by CU-ICAR's facilities, equipment, and staff; now we know that the grad students working here are outstanding as well. We look forward to a long and productive association with Clemson University.

What happens when you cross a world-class unique vehicle development company with a new and innovative automotive engineering graduate program? You come up with a suspension system that can handle speeds in excess of 240 mph, while maintaining all of the comforts of the ultimate luxury automobile.

Because the Clemson University International Center for Automotive Research (CU-ICAR) fills the gap between basic research and commercial application of automotive technologies, DiMora Motorcar challenged CU-ICAR to assess suspension technology options for the Natalia SLS 2 sport luxury sedan. A team of graduate students, under faculty supervision, accepted that challenge last semester.

"This kind of project provides our students invaluable real-world experience, and the quick turnaround time and results show they were up to the challenge," says Dr. Steve Hung, associate professor of mechanical engineering and team faculty leader.

Based in Palm Springs, Calif., DiMora Motorcar crafts automobiles designed to exceed expectations for safety, performance, technology, ecology, beauty, comfort and luxury. It reveals the design, production, and testing of its automobiles via the Internet so that people around the world can learn from and even participate in the process.

"DiMora Motorcar is about showcasing new technologies," says Carl Flesher, CU-ICAR director of Global Business Development. "CU-ICAR is about developing the methods and people to make showcase technologies ready for the automotive original equipment manufacturer market."

Road conditions vary greatly, so an automobile's suspension is crucial to a safe and smooth ride. An effective suspension system will maximize the mechanical grip between the tires and the road's surface, enhance steering stability, and provide a comfortable ride for the occupants. The Natalia sedan has to thrive in all passenger road vehicle environments, including bad weather, so the suspension must be compatible with all-wheel drive (AWD) and have the ability to clear common road obstacles. On the other hand, the vehicle also must be controllable at speeds above 240 mph, so body response to driver inputs and road excitations must be well controlled across a broad speed range. A unique design-driven requirement is the use of 275/40R24 tires.

Using numerous advanced digital design and verification processes, preliminary DiMora Motorcar vehicle parameters, and computer-aided-design (CAD) engineering data for the Natalia, the CU-ICAR graduate team generated a solution that includes short-long arm (SLA) architectures for both front and rear suspensions, titanium control arms and wheel carriers, and combination air spring and damper units.

The concept design satisfies the requirement for AWD, minimizes suspension weight, and allows for rear wheel steering to enhance directional stability at high speeds as well as maneuverability at low speeds. The concept design also will help DiMora Motorcar package other vehicle systems which yield the right levels of performance without significant changes to the suspension system.

"This was our first opportunity to test the ability of the International Center for Automotive Research to tackle a difficult engineering problem that is critical to meeting the performance parameters we have set for the Natalia," noted DiMora Motorcar Founder Alfred DiMora. "The designs they produced are excellent. We were already impressed by CU-ICAR's facilities, equipment, and staff; now we know that the grad students working here are outstanding as well. We look forward to a long and productive association with Clemson University."

Clemson University's International Center for Automotive Research (CU-ICAR) is a 250-acre advanced-technology research campus where university, industry and government organizations collaborate. Offering the nation's only PhD program in Automotive Engineering, the master's and doctoral programs are among the most exceptional in the country due to the world-class faculty, industry involvement in curriculum development and more than $40 million of research facilities/equipment.

Successful automotive technology application requires availability of methods that span design/development integration of technologies to parts, systems and vehicles; manufacturing and supply integration of processes from material sourcing through part creation, assembly and delivery; and concurrent engineering integration of design and development with manufacturing and supply. CU-ICAR conducts research that provides value by addressing the need for these integration methods.

CU-ICAR is a place for entrepreneurial collaboration and partnership between university, industry and government to quickly address market needs together in ways that facilitate economic growth. To learn more about CU-ICAR, please visit
