30 MPH NHTSA Crash Tests

In addition to the 35 mph crash tests I posted in 2012-2014, I am now posting crash tests that NHTSA did in the same manner, but at 30 mph. "The same manner" means a belted driver and front passenger instrumented dummy and a full-frontal impact.
These 30 mph tests were not released as results to consumers "back in the day" like the 35 mph tests were; nevertheless, they are a type of crash test that NHTSA did on numerous different vehicles in the 1970s and 1980s. This is not an exhaustive list of 30 mph full frontal crash tests; some of these tests are so old (the cut-off is around 1978), they're not available on the NHTSA database. Where dummy measures are suspicious or unreliable, this will be noted.

These tests were done beginning in the 1977 model year. Some of these 30 mph tests were done on cars, some were done on trucks, SUVs and vans, and some on electric vehicles. Because NHTSA never did series crash testing on electric vehicles, didn't expand their crash test program to trucks, SUVs, and vans until 1983, and didn't start the 35 mph test until 1979, these are the only frontal crash tests available for many of these vehicles. 

No star rating was given for these vehicles. 

Keep in mind that the 35 mph test has 36% more crash force than the 30 mph test, and thus results aren't comparable. Vehicles could be expected to perform worse at 35, but the degree varied from vehicle-to-vehicle; while most saw a moderate increase, some didn't get much worse, and others saw their HICs and/or chest G's double or more!
