What's new for GM Racing? Well, apart from manufacturing auto parts like GM tail light guards for their race cars, GM also something new for the motorsports industry. The 2007 season of NASCAR Nextel Cup Series is an important event for GM racing team for them to reveal an entirely new racing engine and a completely new engine. GM will be the debut of NASCAR Chevrolet Impala SS "Car of Tomorrow" with R07 small-block V-8 racing engine. Along with the debut of the Chevrolet Impala SS, GM announced its latest developments in vehicle aerodynamics tests as Computational Fluid Dynamics (CFD), which in all GM cars.

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, predicts the aerodynamic forces acting on a vehicle using computer methods rather than physical measurements. CFD allows engineers and racing teams to the effects of aerodynamic changes quickly on a computer screen is not in a conventional wind tunnel.

The CFD software is a supercomputer because the number of calculations is immense. For example, our aerodynamic models usually have more than 10 million discrete points, the data used to calculate the forces. It really is rocket science. "

GM Racing will start the CFD aerodynamic simulation system for next-generation Chevrolet Impala SS to debut in the NASCAR Nextel Cup Series. GM said the CFD engineers use to look at the impact of the new body shape, front splitter and adjustable rear wing of the Impala SS However, although GM said CFD is a powerful engineering tool for the examination of vehicle aerodynamics, it is no substitute for the typical wind tunnel and track testing.

Bayless commented: "Although the Car of Tomorrow is highly regulated, it is not a spec race car. As a manufacturer, Chevrolet was able to many of the details that separate the Impala SS from our competitors' cars. The headlights, grille, and parts of the hood, and the tail were areas where GM Racing was able to Impala SS styling hints and brand identity. These areas are now fixed as part of the NASCAR Impala SS package. "

Just wait and see how the Chevrolet Impala SS "Car of Tomorrow" leads in the NASCAR Nextel Cup Series this season.
