Latest news suggests that USF1 has done some preliminary crash testing. From an interview with Jonathon Ingram on Motorsport.com
"On the road again: This week's Q &A comes from a visit with US F1 owner and designer Ken Anderson last week at the team's shops in Huntersville, N.C., where Anderson was in the middle of preparations for the US F1 debut at the Formula One season opener next March in Bahrain.
Among other things, Anderson said he does not expect to finish the remaining crash tests for the nosebox and rear of US F1's car until late December or early January, choosing instead to spend more time on design. (The lateral test is complete.)
Q: How concerned are you about passing the FIA's mandated crash tests?
Anderson: "It's actually quite easy to pass if you design the parts right. Whatever piece it is, if it weighs ten pounds it will easily pass. But if it weighs nine pounds, eight pounds... . Toyota had 800 people and they had entire departments trying to save an ounce here and an ounce there.
"If you try to save 10 ounces so you can put more tungsten in the bottom of the car, that's a good thing. We're not going to lose the world championship next year because our crash structures are four ounces more than Ferrari's. It doesn't behoove us to go to the last gram.
"We're not going to spend six months crashing 50 noses."
So, they must have a chassis done by now
