They can also use VDDV for crash testing.
"With physical crash evaluations, the amount of obtainable information is inherently limited due to the vehicle being destroyed with each trial," said Anderson. "With virtual testing however, we're able to acquire extensive new data on how the complex network of vehicle systems and components perform leading up to, during and after a crash."
GM doesn't just do one overlap crash test at 25% of the vehicles width at 40 mph. It can do a million, at any overlap, at any speed. "We're trying to get to 100 percent virtual, including the human being," Anderson said. "We have this global human body model and we know more about soft tissue injuries than we used to. We upload thousands of slices of MRIs from real people to get these models right, and all of the pieces talk to each other."
