GM is taking steps to improve its vehicle’s fuel consumptions by focusing on aerodynamics.

General Motors broke ground March 13 on a new $30 million reduced-scale wind tunnel to expand its aerodynamic testing facility on its Warren Technical Center campus.

The company stated this investment will improve test capabilities and support of aerodynamic development, critical to GM’s global CO2 compliance strategy.

GM said the new facility will add a 50 percent increase in reduced-scale testing capacity, a 25 percent increase in full-scale testing capacity and create up to five new jobs. In addition, the new wind tunnel will use a moving ground plane to simulate full driving conditions enabling higher fidelity aerodynamic testing.

A brief ceremony marking the official start of construction attended by GM and City of Warren officials was held at the site.
