The auto industry continues to evolve. The 2025 GMC Terrain is an example of how companies are balancing performance with efficiency. With rising fuel costs playing a crucial role in purchasing decisions, fuel efficiency is more important than ever. In this article, we review the 2025 GMC Terrain’s fuel economy. This includes engine and performance, how it stacks up against previous model years, and practical tips for maximizing fuel economy.

Introduction to the 2025 GMC Terrain

The 2025 GMC Terrain marks the beginning of a new generation for this compact SUV. Sporting an all-new exterior with refreshed sheet metal and a redesigned headlamp that echoes the signature look of the larger Yukon, the Terrain confidently straddles the line between rugged capability and refined urban sophistication. A strikingly modern cabin awaits inside, with a vertically oriented 15-inch infotainment display as the centerpiece. This model, which shares its platform with the Chevrolet Equinox, is available in an elegant Elevation trim with features such as heated front seats, adaptive cruise control, and remote start.

Fuel economy is likely a significant consideration for you when buying an SUV, and the 2025 Terrain answers the call by integrating advanced engineering and design enhancements to reduce fuel consumption without compromising performance. If you are weighing up the potential cost savings on fuel and the environmental benefits of lower emissions, the 2025 Terrain positions itself as a smart choice in the increasingly competitive compact SUV market.

Engine Specs and Their Impact on Fuel Efficiency

Here’s more about how the Terrain’s engine specs impact fuel economy.

Engine Options

The 2025 GMC Terrain is powered exclusively by a turbocharged 1.5-liter four-cylinder engine that churns out 175 horsepower. This engine is designed to deliver quality performance and respectable fuel efficiency—a balance essential for urban driving and long highway roadtrips. Despite being compact, the engine’s design reflects modern engineering trends that focus on optimizing combustion, reducing friction, and improving thermal efficiency.

Transmission and Drivetrain

The Terrain offers two distinct transmission configurations based on your chosen drivetrain. Front-wheel-drive (FWD) models have a continuously variable automatic transmission for smooth acceleration and efficient power delivery. This setup contributes to better fuel economy in city driving and ensures that the engine’s power is utilized as efficiently as possible.

If you opt for all-wheel drive (AWD), the 2025 Terrain has a conventional eight-speed automatic transmission. Although the AWD variant sees a minor trade-off in city fuel efficiency due to the additional weight and drivetrain complexity, it benefits from enhanced traction and stability in adverse driving conditions. The AWD model’s eight-speed transmission is a shift from the previous generation’s nine-speed one. This shows GMC’s commitment to fine-tuning performance while keeping efficiency in focus.

Fuel Economy Ratings for the 2025 GMC Terrain

Fuel economy is often quantified through ratings that estimate how many miles a vehicle can travel on a gallon of fuel under various conditions. For the 2025 GMC Terrain’s gas mileage, early EPA data provides valuable insights into its efficiency. Here’s more about the fuel economy for the new Terrain.

For FWD models, the 2025 Terrain is estimated to achieve:

• City: 26 mpg
• Highway: 28 mpg
• Combined: 27 mpg

In contrast, the AWD versions offer:

• City: 24 mpg
• Highway: 28 mpg
• Combined: 25 mpg

Comparison With Previous Models

Compared with the 2024 GMC Terrain, the 2025 model shows some notable improvements in fuel economy, especially in the FWD variant. For instance, the FWD model sees an improvement of about two mpg in city driving. It went from 24 mpg in the 2024 version to 26 mpg in the 2025 iteration. Additionally, the combined mileage increases by roughly 1 mpg. The all-wheel-drive model has an improvement in fuel economy. It now shows an extra 1 mpg over its 2024 model year for city driving. However, highway and combined ratings remain largely unchanged.

Tips To Improve Fuel Economy

Even the most fuel-efficient vehicle can benefit from smart driving habits and regular maintenance. Here are some practical tips for maximizing the fuel economy of the 2025 GMC Terrain:

• Maintain your vehicle: Keep up with scheduled maintenance, such as oil changes, air filter replacements, and spark plug inspections. A well-maintained engine runs more efficiently and can help optimize fuel consumption.
• Check tire pressure: Underinflated tires increase rolling resistance, which can reduce fuel efficiency. Regularly check and maintain tire pressure at the recommended levels to ensure the vehicle is operating efficiently.
• Adopt eco-friendly driving habits: Avoid rapid acceleration and heavy braking, which wear out your vehicle’s components faster and lead to higher fuel consumption. Instead, try to accelerate smoothly and maintain a steady speed whenever possible.
• Reduce excess weight: Remove unnecessary items from the vehicle as extra weight forces the engine to work harder, thereby reducing fuel efficiency. Only carry what you need, and consider removing roof racks when not in use.
• Utilize eco modes: If your Terrain is equipped with an eco-driving mode, take advantage of it. These settings are designed to optimize engine performance and shift patterns, reducing fuel consumption in everyday driving conditions.
• Plan your routes: Whenever possible, plan your trips to avoid heavy traffic and steep inclines. Utilizing navigation tools to find the most fuel-efficient route can result in significant savings over time.
