Buick Creates 3D Versions of World's Toughest Roads to Virtually Test Vehicles

Buick has turned to a unique road scanning device that replicates the world's toughest roads in 3D form during its quest to create some of the world's most comfortable vehicles.

The Buick team has copied a choppy road leading to the Cerro del Cubilete shrine in Guanajuato, Mexico. The road surface is notorious for its rocks and numerous drivers have reported hearing excessive noise from their vehicles' steering racks. Recreating the road scenario allows Buick to search for ride and noise development issues early and the virtual procedure means early physical prototypes could potentially be better polished for the tuning process. Of course, the virtual Buick vehicles subjected to quality and reliability testing are duplicated as closely as possible.

Buick engineer Mine Tasci explains: "Just like a photo scanner, we can scan the surface of a road to create a three-dimensional digital representation. The scanner works with cameras and a laser to determine a 3D model of a road surface down to 1mm of fidelity. In the end, it leads to higher-quality, quieter and more comfortable Buick cars and crossovers."
