2021 GMC Acadia Review: Not Perfect, But Pragmatic

Semi-premium offerings are always hit or miss; blending the dichotomous values of luxury and affordability is a difficult balance to achieve, and while the 2021 GMC Acadia has its strong points, we can't say that it's a compelling option within the immensely popular midsize crossover SUV classification. Nevertheless, with its audacious design, five trims, and selection of three very different engines, the 5-door Acadia SUV does offer a good amount of choice and value at a reasonable price. The turbocharged four-pot unit offers good pep and fuel-efficiency, too, while the more potent V6 delivers robust acceleration and accords the SUV with a decent 4,000-pound towing capacity. With more contemporary and value-rich cars such as the Kia Sorento, Volvo XC90, and the Mazda CX-9 also in the segment, there remains a lot to be desired from the Acadia.

2021 GMC Acadia Changes: 🚙What’s the difference vs 2020 GMC Acadia?

There has been some shuffling around of features for the 2021 GMC Acadia, along with a few alterations to the color palette and the available packages. The Pro Safety Package, which comprises blind-spot monitoring, rear cross-traffic alert, collision avoidance, front and rear parking sensors, and lane management assist, now comes standard on the SLT, all-wheel-drive SLE, AT4, and Denali. The SLE and SLT get access to the new Elevation Edition, which adds 20-inch wheels and all-season tires, along with blacked-out exterior accents. The Premium Package for the SLT and AT4 has been updated, and the same trims get access to the Technology Package. A pretty significant change for this year is that every model aside from the base SL now seats six with standard second-row captain's chairs. A more minor change is the deletion and addition of several exterior color choices. Finally, Apple CarPlay and Android Auto now offer wireless convenience.

Verdict: 🏁Is the 2021 GMC Acadia a good SUV?

The 2021 Acadia forms part of the second Acadia generation, which was introduced to the US market in 2017. While the Acadia is offered with a good selection of modern creature comforts, conveniences, and technology, it's still not quite as contemporary and rich in value as its newer competitors. The entry-spec engine is barely feasible in such a heavy SUV, delivering lackluster performance and middling fuel economy, but both the turbo-four and V6 are admirable with their bountiful power and torque outputs. One standout perk from the Acadia is its infotainment system, which is both user-friendly and all-inclusive of smartphone connectivity functions. The SUV is also presented with numerous convenience and safety features, and offers various seating configurations between its three rows. A superlative crashworthiness/safety review of the 2021 GMC Acadia from both the NHTSA and the IIHS is matched by high reliability expectations. In review, the Acadia is a pragmatic vehicle, especially for the families looking for a six- or seven-seater at a reasonable price.

🚗What GMC Acadia Model Should I Buy?

The entry-spec 2021 GMC Acadia SUV's price is really compelling at $29,800, but it's stuck with the weak powertrain and a base selection of standard features. The SLT is hence the model we'd recommend as it's presented with the optional turbo-four engine. It also comes with a bunch of inclusive advanced driver-assist systems, such as lane keep assist, lane departure warning, blind-spot monitoring, and rear cross-traffic alert. The SLT can't tow much, however, so if you're going to be hauling more than 1,500 lbs, you may want to consider going for a trim that's equipped with the V6 and AWD.
