The new 2015 Tahoe rates as well as or better than the previous generation of Tahoe, as GM has invested substantial effort in improving the rigidity of the passenger structure, as well as equipping more standard and available safety equipment.
Forward collision alert, park assistance sensors, lane departure warning, lane change assist, rear cross-traffic alert, and adaptive cruise control are among the standard and available options.
All Tahoes offer the segment's only front-seat center airbag (on bucket-seat models), which offers greater protection for front-seat passengers in side-impact crashes.
While the Insurance Institute for Highway Safety (IIHS) hasn't released crash tests for the Tahoe (it tends not to test large body-on-frame SUVs), the National Highway Traffic Safety Administration (NHTSA) has given the Tahoe top five-star ratings for frontal offset and side impact protection. But it achieves a four-star Overall rating due to its lower three-star rollover rating (mostly a factor, again, of the tall body-on-frame construction).
The feds later separately crash-tested a 2015 Chevy Suburban and found that it earned somewhat lower rating in a couple of key areas—four stars instead of five stars in both the Frontal Crash category and the Side Pole test. That still calculates out to the same four-star overall rating for the two models, but it points to the Tahoe as the pick of the two if safety is the top priority.
