Ilmor Engineering: 1.4 TCR = 25% of Engine block assemblies, automotive and truck gasoline, manufacturing BLS 5.4 · 3y Form 300A (see methodology below)

Ilmor Engineering safety composite

Ilmor Engineering scores strongest on total case rate (tcr) (safer than 81% of same-industry peers) and weakest on fatalities (safer than 50%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
