CdA actually considers more factors, as it is Cd (drag coefficient) multiplied by A (the frontal area of the object in question). The value you found has to be Cd...it's far too small to be the CdA value of a vehicle that size unless it has a Cd value of <0.15 (which it doesn't )
For example: Car A has great aerodynamics (Cd=0.25), but a very tall roofline and, consequentially, a large frontal area of 3.0m^2. Car B is less slippery (Cd=0.35), but is smaller overall and has a frontal area of only 2.0m^2. At any speed, Car B will cause less aerodynamic drag and waste less energy overcoming it.
Just in case you're interested, the formula for aerodynamic drag is:
1/2 * rho * velocity^2 * Cd * A where rho is air density (which changes with temperature, altitude, etc)
Think of CdA as Cd times A. It's a coefficient times an area. If the car were doubled in size the coefficient would not change, but the area would.
A jet aircraft has a lower Cd than a motorcycle, but the much smaller area of the bike gives it lower total air drag or CdA.
