There is no room for mistakes in the development of the 2017 BMW M4 DTM. Precision is the key to winning the race. Thus, BMW uses only the latest and the most precise 3D mapping technology in its development.
This is not the first time that BMW announced the use of such technology. In 2016, right before the new BMW G30 5 Series was launched, BMW also released a statement and some photos that showed 3D mapping technology being used in its development. This extremely futuristic technology is the same one used now to develop the BMW M4 DTM.
The system functions using a fully-automated, optical measurement cell. There is none like it in the world. It is able to ensure 100% quality control after the assembly of a race car. The 3D mapping process makes sure that the complex aerodynamics work as planned and tested but also adhere strictly to the specifications laid out in the regulations.
The sensors that are used for the system are accurate down to under 100 micrometers. The measuring cell features two robotic arms that move freely that allow the simultaneous use of two small, flexible robots, each equipped with two sensors, in a relatively small space.
The sensors begin by recording reference points and then scanning individual fields of about 80 x 80 cm in size. Using these measurements, the computer then automatically creates a 3D image of the entire car that is compared to the design plans. Any small difference can be determined and fixed.
