Metrology is a branch of physics which, amongst other things, relates to the scientific study of measurement, the correct implementation of dimensions and the various measuring instruments and methods that are required to undertake full measurement. In Bugatti’s case, Gregoire Haller-Meyer uses classic manual tools as well as high-precision, state-of-the-art 3D scanners with an accuracy of up to 0.005 millimeters. With the aid of the latest and highly complex software, in part from the aerospace industry, he generates precise data for the analysis of the quality, grade, tolerances and dimensions of components.
“All components must be technically and optically perfect in every respect. But, above all, the overall appearance of a Bugatti must be one of perfect harmony. The exterior and interior of each creation must possess a perfect balance between aesthetics, comfort, and quality. For example, I have to find the reason why the gap between two components deviates from our specified tolerances by just one millimeter. After all, this could possibly lead to undesirable noises at the high speeds reached by our hyper sports cars,” Haller-Meyer explains.
After pinpointing the issue, he works with Bugatti’s engineers and craftsman in a closely knit partnership. A customized strategy is crafted for each individual case before being discussed by him to specialists from Molsheim's Atelier or external suppliers when necessary. At times, troubleshooting the issue may necessitate modifying certain components. Although, a replacement part might be necessary in some instances. After installing or fixing the component again, Haller-Meyer guarantees that the prerequisites are met and future problems won't arise.
