Meet the 2025 Buick SUV Lineup

Buick Encore GX
The Encore GX is Buick’s most compact SUV. It blends upscale materials and technology into a city-friendly footprint. With seating for five and a flexible cargo area, it’s ideal for solo drivers, couples, and small families looking for comfort and efficiency.
Buick Envista
The Envista is Buick’s newest and sportiest SUV. With a coupe-like silhouette and striking design, it’s geared toward style-conscious buyers. Despite its sloped roofline, the Envista makes clever use of space and seats five passengers.
Buick Envision
Positioned as a compact-to-midsize SUV, the Envision balances interior spaciousness with sleek design. It’s more accommodating than the Encore GX or Envista and delivers a more traditional SUV stance, perfect for families that require flexibility.

At the top of the lineup is the Enclave, a full-size SUV with three rows of seating and room for up to seven passengers. Designed for larger families or those needing maximum utility, the Enclave offers superior passenger volume and class-leading cargo capacity.

Which Buick SUV is Best for Your Needs?

Best for Maximum Space and Family Utility: 2025 Enclave
If you regularly transport six or seven passengers or often require three-row seating, the Enclave is the clear winner. With the highest front legroom, generous second-row dimensions, and a third row that can accommodate adults or teenagers, it’s built for growing families. It also leads in cargo space behind all rows, making it ideal for weekend getaways and gear-heavy activities.
Best for City Living and Compact Versatility: 2025 Encore GX
Urban dwellers who need a premium small SUV will appreciate the Encore GX. It offers good legroom for front passengers and flexible cargo options for a compact footprint. Rear space is a bit tighter than in the Envision or Enclave, but it's well-suited for short trips with multiple passengers or solo errands with folding seats to boost trunk space.
Best for Balance of Style and Comfort: 2025 Envision
The Envision hits the sweet spot for many buyers, especially those looking for a refined, comfortable ride without stepping up to the larger Enclave. It provides solid rear legroom and generous cargo capacity behind the second row. It's a smart pick for small families or professionals who want a premium feel with everyday practicality.
Best for Design-Driven Buyers: 2025 Envista
The Envista’s standout feature is its design. With its fastback silhouette and youthful appearance, it's made for drivers who prioritize aesthetic appeal and daily drivability. While headroom is slightly less generous due to the sloping roofline, legroom remains competitive. Its cargo area is the most compact, but still flexible enough for light travel or urban use.
Final Thoughts

Buick offers a versatile SUV lineup in 2025 with something for everyone. Whether you're prioritizing maximum passenger capacity, balanced utility, compact convenience, or standout design, there's a Buick that delivers. Here’s a quick takeaway:
- Choose the Enclave if you need three rows, maximum cargo space, and comfort for seven.
- Go with the Envision for a perfect middle ground of interior comfort and upscale features.
- Pick the Encore GX for nimble size and efficient versatility with a hint of luxury.
- Opt for the Envista if design, affordability, and day-to-day practicality top your list.
