Used 2019 GMC Acadia SUV Trims Comparison

Depending on trim, the midsize Acadia is offered in a two-row, five-passenger configuration or a three-row configuration with seating for six (with second-row captain's chairs) or seven (with a second-row bench). A 2.5-liter four-cylinder engine (193 horsepower, 188 pound-feet of torque) is standard on SL, SLE and SLT-1 models. A 3.6-liter V6 (310 hp, 271 lb-ft) is standard on SLT-2 and Denali models and optional on SLE-1 (with all-wheel drive), SLE-2 and SLT-1 trims. Both engines are paired to a six-speed automatic.

Technically, GMC sells an Acadia in the SL trim, with a seven-passenger seating configuration and front-wheel drive. White and silver exterior paint are the only options on this trim. Its features include 17-inch alloy wheels, heated mirrors, keyless ignition and entry, tri-zone automatic climate control, a height-adjustable driver's seat, a leather-wrapped steering wheel, GMC's Teen Driver system, Bluetooth, a 7-inch touchscreen, Apple CarPlay and Android Auto smartphone app integration, a rearview camera, OnStar with 4G LTE and a Wi-Fi hotspot, and a six-speaker audio system with a USB port and auxiliary input.

It's a built-to-order trim, however, so you're most likely going to see the next-level SLE-1 on dealer lots. The SLE-1 trim adds only LED running lights, satellite radio and rear floor mats, while the SLE-2 steps it up with 18-inch wheels, foglights, a power liftgate with programmable height stops, roof rails, remote engine start, an eight-way power-adjustable driver's seat and heated front seats. The SLE-2 and above trims come standard with middle-row captain's chairs that reduce passenger capacity to six, but the second-row bench is available.

The SLE-2's available Driver Alert I package adds blind-spot monitoring with rear cross-traffic alert and rear parking sensors.

Opting for the SLT-1 trim adds the Driver Alert I package, an auto-dimming driver-side and rearview mirror, an upgraded driver information display, a household-style power outlet, leather upholstery, power-adjustable front seats with lumbar adjustment, and an eight-speaker Bose audio system with a subwoofer.

The SLT-2 trim adds 20-inch wheels, the V6 engine, a trailering package (detailed below), driver-seat memory functions and heated outboard middle-row seats. Also included is the Driver Alert II package that has all of the supporting Driver Alert I features, plus lane departure warning and mitigation, forward collision warning (with pedestrian detection and automatic braking at low speeds), automatic high beams, front parking sensors, and a safety-alert driver's seat that buzzes when alerts are triggered.

An 8-inch touchscreen is available on SLE-2, SLT-1 and SLT-2 models. It is paired with the Bose audio system and upgraded driver info display on the SLE-2, and it can be equipped with navigation on the SLT trims.

The top-of-the-line Denali rounds out the lineup with polished wheels, xenon headlights, a unique grille, chrome roof rails, a hands-free liftgate, the 8-inch touchscreen with navigation, a configurable virtual gauge display, ventilated front seats, and a heated and power-adjustable steering wheel. The Denali is also eligible for the optional Technology package that adds a 360-degree parking camera and adaptive cruise control.

You can get all-wheel drive on all Acadias except the base SL. A two-panel sunroof is available on SLE-2 trims and above. An All Terrain package is also available on SLE-2 and SLT-1 trims and adds the V6 engine, distinct exterior treatments, hill descent control, a more advanced all-wheel-drive system and a cargo management system (SLT-1 only). If five-passenger seating is specified, tri-zone climate control is replaced by dual-zone control with rear air vents. A trailering package is standard on SLT-2 and Denali trims and optional on SLE-2 and SLT-1 trims with the V6 engine. It includes a trailer hitch, a seven-pin wiring harness, a heavy-duty alternator and cooling system, and a dotted line in the rearview camera to show the hitch location. Finally, a special suspension with adaptive dampers is optional for AWD SLT-2 and Denali trims.
