GM built the first full-scale wind tunnel in North America, but that wasn't until 1980.
General Motors' wind tunnel turns 30, more important than ever

Now it runs almost constantly and modern cars get hundreds of hours in the wind tunnel.
Before that, they tested using scale models, but clearly they had a lot of room for improvement.
