Chevrolet Impala SS Ready for NASCAR 2007 Season

The 2007 season of the NASCAR Nextel Cup Series is an important event for GM Racing team for them to unveil a brand new racing machine and an all-new engine.Here is how Kevin Bayless, GM Racing oval track chassis/aero Program Manager explains how the CFD works: "The best way to describe CFD is a wind tunnel in a computer. CFD is a simulation that predicts the aerodynamic forces acting on a vehicle using computational methods rather than physical measurements. GM will make the NASCAR debut of the Chevrolet Impala SS "Car of Tomorrow" along with R07 small-block V-8 racing engine.CFD also allows us to test aerodynamics without a physical model,GM said engineers utilized the CFD to gain insight into the effects of the new body shape, front splitter, and adjustable rear wing of the Impala SS. However, GM said although CFD is a powerful engineering tool for testing vehicle aerodynamics, it is not a replacement for the typical wind tunnel and track testing. which can be helpful in the early stages of a design. We can analyze and compare various alternatives before actually building a prototype vehicle." he further explains.As a manufacturer, Chevrolet was able to define many of the details that separate the Impala SS from our competitors' cars. The headlights, grille, portions of the hood, and the tail were areas where GM Racing was able to incorporate Impala SS styling cues and brand identity. These areas are now fixed as part of the NASCAR Impala SS package."
