$32,190 · Crossover

Comparison Overview

The 2025 GMC Terrain arrives with rugged, upscale styling and an emphasis on accessible efficiency, boasting 175 horsepower and an impressive 27 MPG combined for daily errands. Conversely, the 2026 Kia Sorento offers a more substantial presence, slightly edging out the Terrain with 191 horsepower, though its efficiency dips marginally to 26 MPG combined. While the Terrain is more compact at 181.0 inches long, the Sorento provides a greater highway cruising advantage with 31 MPG highway compared to the Terrain's 28 MPG highway. However, the Sorento’s smaller 12.6 cu ft of standard cargo space—significantly less than the Terrain's 29.8 cu ft—is a notable trade-off. Starting at $30,000, the Terrain presents a compelling entry point against the Sorento's $32,190 MSRP, creating a clear dynamic between straightforward utility and slightly stronger base power.

Frequently Asked Questions

Which crossover is better for long-distance highway cruising efficiency?

The 2026 Kia Sorento has a slight edge on the highway, achieving 31 MPG compared to the 2025 GMC Terrain's 28 MPG highway rating. However, the Terrain might feel slightly more compact to maneuver given its 181.0-inch length versus the Sorento's 189.6 inches.

How significant is the difference in standard cargo capacity?

The difference is dramatic; the 2025 GMC Terrain offers 29.8 cubic feet of cargo space, which is more than double the 2026 Kia Sorento’s standard 12.6 cubic feet. This makes the Terrain the clear victor for hauling gear.

Does the power difference between the two models feel substantial?

The 2026 Kia Sorento produces 191 horsepower, offering a noticeable 16 horsepower advantage over the 2025 GMC Terrain's 175 horsepower. Both utilize front-wheel drive, but the Sorento is engineered for slightly stronger acceleration.

Why does the 2025 GMC Terrain cost less than the 2026 Kia Sorento?

The Terrain starts at $30,000, undercutting the Sorento's $32,190 MSRP, making it a more budget-conscious choice upfront. This difference likely reflects variances in standard features or platform structure not detailed here.

How does the transmission choice affect the driving experience?

The Terrain uses a continuously variable-speed automatic (CVT), which generally favors smoother, consistent acceleration paired with efficiency. The Sorento uses a conventional 8-speed automatic, often preferred by drivers who enjoy distinct gear shifts and better control.

Are both vehicles comparable in overall size?
