TheCarConnection.com gives the GMC Envoy for 2008 only average marks for safety, due to relatively poor front-impact crash performance.
The National Highway Traffic Safety Administration (NHTSA) awards the Envoy GMC excellent marks in side impact tests--which is good, since most injuries result from side impacts--but both this agency and the more stringent Insurance Institute for Highway Safety (IIHS) give the 2008 GMC Envoy much lower marks in frontal impacts. The NHTSA’s front-impact rating is only three stars for the driver, far off the mark for most new cars.
That score comes despite the Envoy’s extensive safety gear. Standard safety equipment in the GMC Envoy, according to Cars.com, includes "all-disc antilock brakes, electronic stability control and side curtain airbags and a tire pressure monitoring system; Edmunds reports that "the 2008 GMC Envoy gains head curtain airbags as standard equipment."
Visibility poses few problems aboard the Envoy. GMC’s design has "enough glass around the sides to give the driver a good 360-degree view," according to Kelley Blue Book. On the other hand, ConsumerGuide says that while "the driver has a good view to the front and sides" in the GMC Envoy, "headrests and roof pillars hamper lane changes and backing up."
