A new special edition for the Suburban is available for 2018: the street-performance Rally Sport Truck, or RST. Suburban is the original SUV. Offered in LS, LT and Premier models, in 2WD and 4WD configurations. Suburban’s powerful V8 is the perfect combination of performance and fuel economy, offering efficiency without compromising power and towing capability. Suburban features an acoustic-laminated windshield, inlaid doors with triple seals, acoustic wheel house liners and exterior/interior dash insulation to help reduce noise in the SUV’s cabin. Available power-release second-row and power fold-flat third-row seats gives Suburban a versatile interior that’s ready for anything.
