Cadillac CT6

Where it stands out against its peers

• Power train: more complaints than 99% of 2017 cars — 65% of its 26 complaints, where an ordinary 2017 car has 14%.

Same model year only, at least 30 peer cars, zeros included. Every car has a worst part; this shows which, and how far from ordinary it is. A high share means more to check, not a verdict.

Crash test

Crash-tested by NHTSA, the American road safety agency.
