Ford to invest $200 million in new wind tunnel

Ford said today it will invest $200 million to build a new wind tunnel in Dearborn, giving the automaker a new test facility that will help it design more fuel-efficient cars and trucks.

The Dearborn automaker already has several wind-tunnels around the world, including one in Allen Park, but hasn’t significantly upgraded them since the 1990s.

The new wind tunnel will enable the automaker to simulate wind speeds of up to 200 mph. It will also include a climate chamber with temperatures as low as minus 40 degrees Fahrenheit and as high as 140 degrees Fahrenheit.
