CarGurus Analysis: 2020 GMC Terrain
Summary
With 127 currently listed for sale near Houston, TX and an average price of $16,314.00, 24.4% of 2020 GMC Terrains for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2020 GMC Terrain 4.43 / 5 stars.
78.0% of 2020 Terrain models on CarGurus are accident free.
Why it stands out
The 2020 GMC Terrain stands out as a compact SUV that leans more toward comfort and premium touches than outright utility. For 2020, the Terrain lineup was updated and important safety technology such as automatic emergency braking, forward collision alert, lane-centering, lane-departure warning and front pedestrian braking became standard. That makes it appealing to buyers who want a small SUV with a strong safety feature set and a more upscale feel than many rivals.
It also offers a useful mix of powertrain choices for shoppers who care about efficiency or capability. The standard 1.5-liter turbocharged engine produces 170 horsepower, while the optional 252-horsepower 2.0-liter turbocharged four-cylinder is the choice for buyers who want more performance. The Terrain’s cabin benefits from GMC’s infotainment technology, with many models featuring an eight-inch touchscreen, and Apple CarPlay and Android Auto are standard. The 2020 Terrain Denali is especially notable because it pairs the more powerful 252-horsepower engine with the upgraded suspension package that Denali received that year.
There are trade-offs, though. The 1.5-liter engine’s highway acceleration isn’t very good, and cargo space trails that of some popular rivals. Buyers who prioritize maximum towing capacity or stronger performance will likely prefer the 2.0-liter engine, while those focused on value may appreciate that late-model Terrains generally cost less than some Japanese competitors.
