Confidence in results

I admit to being surprised by this marketing blurb for newly released Caterpillar road prime movers:-


"Computational Fluid Dynamics, a computerised application used to optimised design, was used in the early stages of the process; 1/8 scale wind tunnel testing was used for basic shape development; as well as full scale wind tunnel testing."


Is this typical in high tech engineering industries?
