2024 GMC Terrain SLT Engine, MPG, Specs

2024 GMC Terrain SLT Engine, MPG, SpecsFor the 2024 model year, GMC has updated the already excellent Terrain. Many things have changed, including the elimination of the SL basic trim and the addition of the AT4 off-road version. In addition, the 2024 Terrain has revised front and rear fascias, three new exterior paint colors, modified wheel designs for 18 and 19 inches, and fixed upholstery and trim materials within. A new head-up display has been installed inside the SUV, and the entertainment system now supports wireless Android Auto and Apple CarPlay. The new Terrain SLT trim will have the Tech Package by the end of 2023.

2024 GMC Terrain Interior

In terms of engines, the 2024 GMC Terrain retains the same 1.5-liter turbocharged inline-4 as its predecessor, which generates 170 horsepower and 203 pound-feet of torque. There is a modest cost for the smartly designed, roomy, and well-equipped interior. The exterior design, however, is what makes this vehicle stand out in the crowded market of compact sport utility vehicles. With a starting MSRP of $29,695, the 2024 GMC Terrain competes for head-on with the likes of the Toyota RAV4, Mazda CX-5, and Honda CR-V.

2024 GMC Terrain Redesign

The GMC Terrain’s hefty truck-like front appearance and large overhang are surprising features for a crossover with a 1.5-liter engine. In contrast, a long overhang negatively affects off-road, approach, and departure angles—the AT4 sports a front skid plate and all-new 17-inch wheels, among other visual distinctions. In 2024, the exterior will receive a facelift with a sleeker front and fascia and updated LED headlights and taillights. Marine Metallic, Cayenne Red Metallic, and a stylish new hue, Desert Sand Metallic, are the latest additions to the palette.

The remainder of the GMC Terrain remains unchanged, so expect the same features like black lower body trim, deep-tinted rear glass, heated power-adjustable mirrors, roof rails, and fog lights (halogen). Roof racks, a SkyScape motorized sunroof, side steps, and a few more external accouterments are available as extras. The GMC Terrain is the most significant, 182.3-inch length and a 107.3-inch wheelbase. The Toyota RAV4 towers above the competition with a height of 67 inches and 8.4 inches of ground clearance.

While the inside is roomy and comfortable, the poor construction and average selection of materials are significant drawbacks. Unfortunately, the tiny crossover Terrain’s interior is further harmed because its push-button shifter is awkward to use. Located on the center console, it is hardly the most user-friendly thing in the world. The controls resemble power window switches and are arranged in a confusing layout. We suppose owners will get used to the design eventually, but in the meantime, we had difficulty swiftly performing three-point turns or switching to manual mode because of the small buttons. This was especially true when fumbling for reverse. The Terrain is a reliable travel companion for hauling a heavy cargo of varying dimensions. The show and rear seats can be folded completely flat, and the back seats fold in a standard 60/40 configuration. The cargo capacity of the Terrain is comparable with the best in its class. The Terrain passed our test with 24 carry-on luggage cases, but customers who want the most cargo space should look at the CR-V instead.

Terrain’s infotainment system has intuitive visuals, menus, and the most up-to-date in-car connection technologies, making it simple to use and quick to respond to orders. It has wireless Apple CarPlay, Android Auto, and a Wi-Fi hotspot. The top-tier Denali has a standard navigation system, while other versions provide it as an optional extra. The Terrain’s head-up display comes standard on the Denali and can be added to the SLT and AT4 as an option. Unlike other GM cars, the information doesn’t appear on the windshield but in a pop-up panel at the top of the dashboard.


There is only one machine choice for the 2024 GMC Terrain: a 1.5-liter turbocharged inline-4 that generates 173 horsepower and 203 pound-feet of torque. For the 2024 model year, the 2.0L turbocharged inline-4 engine is no longer available. All of the power from the 1.5L turbocharged engine is sent to the front wheels through a 9-speed automated transmission. An all-wheel-drive system is also an option. Regarding driving and handling, the 1.5L holds its own; it pushes the crossover with relative ease and travels the highway at a fair clip. Additionally, a 0–60 MPH speed of 9.3 seconds is praised by regular motorists. All-wheel drive is a good idea since it improves handling on infrequent occasions when you need to travel through challenging Terrain while giving you more confidence when driving.

The Toyota RAV4 has the most incredible power, with 203 horsepower and 184 lb-ft of torque, which is 33 more than the GMC Terrain. The Mazda CX-5, which comes in second to the RAV4, is the quickest of the bunch due to its 187 horsepower and 8.1-second 0-60 mph time. The Honda CR-V finishes in second with its 190 horsepower and 7.7-second sprint pace. The GMC Terrain is the weakest in raw power and the 0-60 mph sprint. If reports are to be believed, GMC will not adjust the 2024 Terrain’s fuel efficiency from the 2021 model. The EPA estimates 25 city mpg, 30 highway mpg, and 27 combined mpg for the 2024 terrain. When the AWD system is used, the gas mileage goes down by two mpg on the highway and one mpg in the city.
