Quatro Composites Validates Chassis Design for DiMora Natalia

11 August 2007

Quatro Composites 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 fibre technology - that they say 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 fibre 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.”
