The Car Connection's Take
TCC Rating
6.8
6.6
TCC’s Bottom Line
The 2018 Chevrolet Suburban is the ultimate weekend road-trip vehicle ready to haul nine people, their luggage, and even an 8,300 pound trailer. Try that in a crossover. A nip and tuck for this year isn't enough to ignore the wrinkles in the aging 2018 Infiniti QX80.
