Ford decided to spend lots of money on a high-tech wind tunnel facility. The automaker hopes on improving the fuel economy of its cars with the new technology. The facility will feature tunnels that can handle an array of situations including high speeds, extreme temperatures, and large vehicles. On the performance front, one of the tunnels will feature special fast-moving belts, also called rolling roads, that will direct air around the car at up to 200 mph depending on how the multi-belt system is configured. That faster belt system will be useful for Ford's sports cars and race cars. Ford also says the five-belt system will be useful for improving aerodynamics for fuel efficiency.
