What good is 500 horsepower if it doesn't translate into
speed? Yet when it comes to determining how fast a car is, there's another
important factor in the equation: aerodynamics.
When comparing two cars of equal engine power and equal
weight, the body of each car can make all the difference: the lower its air
resistance or drag, the faster the car will be. As Porsche has proved time and
again in the 24 Hours of Le Mans and many other races, aerodynamic refinements
such as a streamlined underbody and wings help a race car reach high speeds
while still allowing the driver to maintain control of the vehicle.
