Aug. 10, 2007 (Orange City, IA) - Quatro Composites, a leader in carbon fiber
design and manufacturing, has become the latest Technology Partner to support DiMora
Motorcar’s development of the Natalia SLS 2 sport luxury sedan. Their design parameter
analysis enabled DiMora to refine the design of its radical chassis—based upon carbon
fiber technology—that will be far lighter and stronger than those used in other luxury
automobiles.

A series of Finite Element Analysis (FEA) tests were performed on the Natalia’s chassis
design at Quatro’s Technical Development Center in Poway, California. The proprietary
OptiPart™ methodology was used to develop an optimum product design for improved
performance characteristics for the world’s first hand-built, $2 million, 16-cylinder
production automobile.

“The primary goal of the analysis was to achieve optimal torsional and bending stiffness
of Natalia’s revolutionary chassis, while also minimizing weight,” explains Quatro’s
Development Engineering Manager. “Our OptiPart™ design process helps identify areas
where the stiffness, strength, vibration characteristics, and crash performance properties
can be improved.”

DiMora Motorcar Founder and CEO Alfred DiMora notes that “Quatro Composites has
an impressive understanding of the properties of carbon fiber technologies and the
innovations they facilitate. Their experience in aircraft design is directly applicable to the
Natalia SLS 2, as we integrate aerospace technology developments as much as
automotive innovations. Their analysis both validated our design and identified places
where a minor change would yield a major improvement in stiffness or other
characteristics. They are an important part of the DiMora design development team.”

Quatro’s OptiPart™ design service allows customers to optimize a products carbon fiber
design and composite manufacturability. Quatro designs and manufactures carbon fiber
composite components for a variety of industries. Corporate headquarters and
manufacturing facilities are located in Orange City, Iowa.
