1/10 scale up to 40% scale models

GM's Reduced Scale Wind Tunnel latest testing facility and their 'Honey I've shrunk the kids' models are not just the exterior shells but also include 3D printed highly detailed engines, moving suspension hardware and detailed underbody contours to properly test functional performance on a rolling conveyor road/belt system. Aero-thermodynamic analysis of the component cooling and under body flow effects can also be tested. The downscaling allows to test the new model designs up to 155 mph. The old-school clay models have a limited test life as they eventually dry out, change shape and are destroyed. The new super-realistic and quicker prototyping with ABS, PC or ULTEM thermoplastics are more accurate, durable, repeatable and stable over time.
