This paper describes the performance attributes of the all-new front and rear SLA (short-long arm) suspensions, steering system, and tires of the 1997 Corvette. The process by which these subsystem attributes flowed down from vehicle-level requirements for ride and handling performance is briefly described. Additionally, where applicable, specific subsystem attributes are rationalized back to a corresponding vehicle-level performance requirement. Suspension kinematic and compliance characteristics are described and contrasted to those of the previous generation (1984 to 1996 Model Year) Corvette. Both synthesis/analysis activities as well as mule-level vehicle development work are cited for their roles in mapping out specific subsystem attributes and related vehicle performance.

This paper describes the hardware execution of the front and rear suspensions of the all new 1997 Chevrolet Corvette. Topics covered include: alternative design trade-off, mass optimization, alignment and trim, structural interfaces, shared components, component design and a review of the overall design of the front and rear suspensions. Two case studies are detailed for the front upper and rear lower control arms. The systems engineering process used for suspension design is described throughout the paper.

The process of gathering information, analysis, and selection of ride and handling goals for the 1997 Chevrolet Corvette is described. The goals consist of measurable objective metrics and standardized subjective evaluation. The input elements of the process are: the Voice of the Customer, Engineering Direction and Competitive Assessment. As values are developed for the each metric, synthesis and analysis methods are used to confirm the full set of metrics are consistent and non-exclusive. The targets selected guided the chassis design and development of the 1997 Chevrolet Corvette to insure outstanding customer satisfaction in handling and ride.
