Simulation of race circuit performance had a significant impact on the design and development of the Dodge Stratus North American Touring Car Championship (NATCC) entry. The analysis involved utilization of the Milliken Research Associates, Inc. (MRA) Lap Time Simulation (LTS) program which predicts lap time based on data describing the vehicle, tires, and race track. Input data for the simulation was obtained from several sources. Chrysler Vehicle Engineering provided vehicle design information and engine power data. Tire characteristics were measured at Calspan Corporation. Aerodynamic coefficients were derived from scale model wind tunnel tests performed by Reynard Racing Cars Ltd. at the Houghton Wind Tunnel, Royal Military College of Science Shrivenham, Wiltshire, UK. X-Trac Ltd. provided transaxle specifications and race line data was derived from on-board measurements and circuit maps. Parametric studies of the vehicle variables were performed for various tracks.

The MRA Moment Method computer program automates an original approach to the analysis of race car handling. For a given speed and power/braking condition, the computer solution covers the full maneuvering envelope and presents the results graphically in one figure. The model is based on a comprehensive nonlinear vehicle representation utilizing tire, chassis, and aerodynamic input data as available to race car designers and developers. The paper will first explain and illustrate the Moment Method in general terms, with some graphical examples. The ability of the technique to model the behavior of an F.1 car traversing a small bump in mid-corner on a Grand Prix circuit is then reviewed. The results correlate well with the driver comments relative to changes in directional stability (plow/spin) as the car pitches over the bump. It also correlates well with the lateral acceleration/speed that the driver is willing to use in this corner.

Written for the engineer as well as the race car enthusiast, Race Car Vehicle Dynamics includes much information that is not available in any other vehicle dynamics text. Truly comprehensive in its coverage of the fundamental concepts of vehicle dynamics and their application in a racing environment, this book has become the definitive reference on this topic. Although the primary focus is on the race car, the engineering fundamentals detailed are also applicable to passenger car design and engineering. Authors Bill and Doug Milliken have developed many of the original vehicle dynamics theories and principles covered in this book, including the Moment Method, "g-g" Diagram, pair analysis, lap time simulation, and tire data normalization. The book also includes contributions from other experts in the field.
