Smaller than the previous model, the handsome 2018 GMC Acadia manages to maintain its niche among midsize, three-row SUVs. The available Acadia Denali grade supplies peak trim and amenities worthy of comparison to other premium models.

What's New for 2018

The most significant change for 2018 is an All Terrain Package offered on select SLE and SLT models. This package offers special trim, exclusive five-passenger seating (six- and seven-passenger seating is available), along with covered storage bins and a cargo management system in two-row models. Denali models gain an automatic heated steering wheel.

Choosing Your GMC Acadia

GMC offers the Acadia in four grades: SL, SLE, SLT and Denali. The SLE and SLT divide further into a pair of sub-trims — SLE-1, SLE-2, SLT-1, and SLT-2. Front-wheel drive is standard and all-wheel drive is available on all but the base trim, adding $2,000 to your price. Seating is for five to seven passengers. Cargo volume measures 12.8 cubic feet behind the third row, 41.7 cubic feet behind the second row, and 79 cubic feet behind the first row.

Aside from the SLT-2 and Denali, a 2.5-liter four-cylinder engine generating 193 horsepower and 188 pound-feet of torque is standard. As for the SLT-2 and Denali, these two get a 3.6-liter V6 making 310 horsepower and 271 pound-feet of torque – the V6 is a $1,095 option on the SLE-1 (where it requires all-wheel drive, making the effective price $3,095) and on the SLE-2 and SLT-1, where it's available with both front- and all-wheel drive. Both engines work alongside six-speed automatic transmissions.

Optional packages are available on all but the base Acadia, although the bulk of it is just dealer-installed protection equipment.

GMC Acadia


The base 2018 GMC Acadia SL costs $29,995 (Including a $975 destination fee). This model has projector beam headlights, daytime running lights, power-adjustable heated side mirrors, and 17-inch aluminum wheels. Full power accessories, cruise control, an audio package with a 7-inch screen, six speakers, Bluetooth connectivity, Apple CarPlay and Android Auto compatibility, OnStar 4G LTE WiFi hotspot, and a rearview camera round out the tech features.

The SL is only available in two exterior colors – a no-cost Summit White and Quicksilver Metallic, which demands $395. Black cloth is the only available upholstery.

As mentioned, there are no package options on this trim.

GMC Acadia


GMC prices the SLE-1 from $33,535. This model adds LED daytime running lights, satellite radio, carpet floor mats, and a spare tire. As is usually the case with General Motors' brands, the second trim level in the Acadia lineup will likely represent the real-world base trim, with the Acadia SL reserved largely for rental service and other fleet uses.

Moving to the SLE-1 opens up the color palette (although Summit White is the only no-cost paint option – aside from the $495 Crimson Red Tintcoat, all other shades add $395 to the Acadia's price) and offers contrasting light and dark Ash Gray cloth as an alternative to black.

You’ll also find five package options. A Cargo Package ($315) adds an integrated cargo liner, cargo net and cargo shade. Choose the Floor Liner Package ($260), adding floor liners across all three rows. The Interior Protection Package ($300) brings in all-weather floor mats across all three rows and in the cargo area. The Protection Package ($375) adds front and rear splash guards to the Interior Protection Package. A Black Accent Package ($1,195) embellishes this model with dark finish on the grille and surrounding the rear license plate and across the rear taillamp finish. Each of these packages is available across the Acadia line for the prices listed here. The sole exception is the Black Accent Package, which isn't available on the range-topping Acadia Denali.

Starting from $36,155, the SLE-2 brings in fog lamps, a power liftgate, heated front seats, and an eight-way power driver’s seat. Beginning with this trim, a pair of bucket seats substitute for the center bench seat. The SLE-2 is available with a Driver Alert Package I ($790) with rear park assist, blind-spot monitoring and rear cross-traffic alert. The SLE-2 adds White Frost Tintcoat paint for an additional $995.

The same packages offered on the SLE-1 carry forward here, along with an Exterior Convenience Package ($860) bringing in roof rack cross rails and molded assist steps.

GMC Acadia


Priced from $39,435, the SLT-1 adds leather seats, an 8-way power passenger seat with lumbar support, an auto dimming driver-side mirror and rear-view mirror, eight-inch touchscreen infotainment, an eight-speaker Bose audio system, and a 120-volt outlet. The Driver Alert Package from the SLE-2 is standard equipment from this point on. Cocoa leather upholstery replaces the Ash Gray option.

GMC Acadia


Costing from $42,835, the SLT-2 adds the V6 engine as standard, 20-inch machined aluminum wheels, and heated second-row seats. The Acadia’s Driver Alert Package II (which, weirdly, doesn't appear to be available as an optional extra anywhere else) is standard at this trim level building on the basic package with low-speed automatic braking, lane keep assist, following distance indicator, forward collision alert and safety alert driver seat. All other package options carry forward.

GMC Acadia


The top-of-the-line Denali trim costs from $45,995. This model offers a Denali grille along with copious amounts of chrome, 20-inch polished aluminum wheels, bright roof rails, a power tilt-and-telescopic steering column, and forward-collision alert. The Denali trim offers a Technology Package ($1,395) bringing in adaptive cruise control, forward automatic braking, and a surround vision system. All other package options carry forward.

CarsDirect Tip

In the Acadia, GMC offers a dizzying array of trims, packages and upgrades. Our pick is the SLE-2 with the base engine with all-wheel drive recommended wherever wintry conditions are prevalent. Add in the Driver Alert and Exterior Convenience packages and your out-the-door price comes to $40,900.

Battling in a competitive segment, the 2018 GMC Acadia must perform a delicate balancing act, offering consumers good value and a competitive feature set. For the most part, the Acadia, now in its second year following a redesign, succeeds in its attempts at hitting the sweet spot in many areas, but its imperfect in others.

Best Value

Outside of its standard engine, the base GMC Acadia is a decent buy. Sure, its $29,995 price tag (including a $975 destination charge) may seem high, but the Acadia has a lot to offer, even in its base trim (push-button start, three-zone climate control, a seven-inch infotainment system with Apple CarPlay/Android Auto). That said, we recommend moving a little upstream to the $36,155 SLE-2 trim and opting for the 3.6-liter V6 engine, which adds another $1,095 to the bottom line. This engine delivers a more satisfying driving experience than the base four-cylinder with only a small drop in fuel economy.

We also suggest adding a few optional packages, like the Driver Alert Package and the Exterior Convenience Package. These include desirable features like rear park assist, rear cross-traffic alert, roof rack cross rails, and more with just another $1,650 investment.

GMC Acadia
  • Model: 2018 GMC Acadia FWD SLE-2
  • Engine: 3.6-liter V6
  • Output: 310 hp / 271 lb-ft
  • Transmission: Six-speed automatic
  • MPG: 18 City / 25 Hwy
  • Exterior color: Summit White
  • Interior color: Dark Ash Gray / Light Ash Gray
  • Options: Driver Alert Package ($790, rear park assist, rear cross-traffic alert, and lane-change alert), Exterior Convenience Package ($860, roof rack cross rails and molded steps), 3.6-liter V6 ($1,095).
  • Base Price: $36,155
  • As Tested: $38,900

Performance Pros

  • Delivers a polished and comfortable ride
  • Optional 310-hp V6 engine has plenty of power
  • Nicely weighted steering system

Performance Cons

  • 20-inch wheels result in a stiffer ride
  • Acadia All Terrain models are more about looks than actual off-road performance
  • Four-cylinder engine just doesn’t have enough punch

Interior Pros

GMC Acadia
  • Interior feels well put together and comfortable
  • Standard seating for up to seven
  • Even the base SL trim has a good number of features

Interior Cons

  • Downsized as part of its redesign, the Acadia starts feeling cramped with a full load of passengers
  • The range-topping Denali trim doesn’t feel luxurious enough for the price
  • Styling is average at best and derivative at worst

Our Favorite Thing

For a crossover, the Acadia does a nice job balancing a comfortable ride with decent handling. Add the optional V6 engine, and you can also include straight-line acceleration as a positive.

Our Least Favorite Thing

Prices skyrocket quickly, especially when you add safety tech. Buyers can only get the all-important automatic emergency braking in the SLE-2 and higher trims, pushing the starting price up to $42,835 ($975 destination fee included). Many of the Acadia's competitors now offer this safety technology as optional across their entire lineup or even as standard equipment (we're looking at you, Honda Pilot).

Right For

GMC Acadia

Established buyers willing to shell out a little more money to get away from the base engine will enjoy the 2018 Acadia. It’s also great for growing families, as its optional third row offers plenty of versatility.

Wrong For

Buyers looking to sneak into a larger model by buying the entry-level trim won't find a friend at GMC. While the Acadia’s features at the base level are plentiful, its pricing is a bit prohibitive in the lower trims, and its base engine leaves a lot to be desired.

The Bottom Line

In its middle to upper trim levels, the 2018 GMC Acadia is a great crossover that we’d highly recommend. That said, its lower trims are priced higher than many competitors, and the standard four-cylinder engine lacks the punch to move this midsize crossover, especially with a full load of passengers.
