When an automaker is in the third year of a product cycle, the updates are usually predictable: a few software tweaks, maybe a new wheel design, and a reshuffled color palette. The 2027 Buick Enclave fits this formula perfectly. It is a direct continuation of the third-generation platform that launched for the 2025 model year. It is not a new platform, and it is not a mid-cycle refresh—that is expected for 2028.
However, what the 2027 model lacks in mechanical novelty, it attempts to make up for in sheer curb appeal, courtesy of a striking new paint option: Blue Onyx.
The Blue Onyx Factor (Avenir Exclusive)
In the luxury and near-luxury SUV segments, color exclusivity is a common tactic to drive buyers toward higher trims. Buick is playing this card heavily for 2027.
Blue Onyx (paint code G46) is a deep, highly reflective metallic blue that looks almost black under overcast skies but pops with heavy metallic flake in direct sunlight. Crucially, Buick has locked this color exclusively to the top-tier Avenir trim. You cannot get a Preferred or Sport Touring (ST) Enclave in Blue Onyx.
By tying their most dynamic new color to the Avenir, Buick is deliberately reinforcing the trim’s flagship status. If you see a Blue Onyx Enclave on the road, you immediately know it is the most expensive version Buick sells. To complement the exterior, the 2027 Avenir also gains a new Cool Gray and Twilight Ash interior color scheme, along with trim-exclusive 22-inch wheels featuring a pearl nickel finish.
Powertrain and Performance: Adequate, Not Aggressive
Underneath the new paint, the mechanicals remain identical to the 2025 and 2026 models. The Enclave is powered by a 2.5-liter turbocharged four-cylinder engine producing 328 horsepower and 326 lb-ft of torque. This powertrain is shared across GM’s large crossover portfolio, including the Chevrolet Traverse and GMC Acadia.
- Transmission: 8-speed automatic
- Drivetrain: Front-wheel drive standard; All-wheel drive available
- 0-60 mph: Approximately 6.8 seconds
- Max Towing: 5,000 pounds (with available factory hitch)
On the road, the Enclave prioritizes isolation over engagement. The power delivery is smooth but unhurried, and the suspension (especially the Avenir’s premium setup with Continuous Damping Control) is tuned to erase potholes rather than carve corners. It is exceptionally quiet and comfortable, but it won’t raise your pulse.
Cabin Tech: Screens and Super Cruise
The centerpiece of the Enclave’s interior remains the massive 30-inch diagonal curved display that seamlessly houses both the digital gauge cluster and the infotainment system. The graphics are crisp, and the system runs on Google Built-in, which now includes Google Gemini AI integration as standard equipment for 2027.
The biggest tech upgrade for 2027 buyers is that GM’s highly regarded Super Cruise hands-free driving system is now standard equipment on the Avenir trim (it was previously an option). Furthermore, Buick has added two new camera features: a Surround Vision Recorder and a Cabin Glance interior camera for added security.
The Practicality Play
Where the Enclave truly excels is in raw footprint. It borders on full-size SUV dimensions, making it significantly larger than many of its mid-size luxury competitors.
- It features standard second-row captain’s chairs.
- The third row is genuinely usable for adults on shorter trips.
- With the third row folded flat, the cargo area is cavernous, easily rivaling the hauling capacity of much larger, truck-based SUVs like the Chevy Tahoe.
The Verdict: Buy Now or Wait?
The 2027 Buick Enclave Avenir in Blue Onyx is a deeply competent, highly comfortable highway cruiser. If you value a hushed cabin, massive cargo space, and the relaxation of Super Cruise, the Avenir trim is a compelling, if slightly understated, luxury offering.
However, buyers should be aware of the product cycle. Automotive industry sources widely expect a mid-cycle refresh for the 2028 model year. A 2028 update will likely bring revised front and rear styling, updated interior materials, and potentially new tech.
If you want the most refined, proven version of the current generation—and that exclusive Blue Onyx paint is calling your name—the 2027 is a safe bet. But if you prefer to have the latest exterior styling, you might want to hold off for another 12 to 18 months.
