2021-2024 GMC Terrain II (facelift ) 1.5L turbo (173 Hp) AWD Automatic

The GMC Terrain II, specifically the facelifted version introduced in 2022 with the 1.5L turbocharged engine paired with an automatic transmission and all-wheel drive (AWD), represents a significant iteration in GMC’s compact SUV offerings. Production spanned from 2021 through August 2024, positioning this variant as a mainstream choice within the Terrain lineup. This model year saw updates to the exterior styling, interior technology, and refinement of the powertrain, aiming to enhance its appeal in the highly competitive North American SUV market. The 1.5L turbo AWD Automatic trim served as a popular, well-rounded option, balancing fuel efficiency, capability, and price point.

Technical Specifications

INTRODUCTION

The 2022-2024 GMC Terrain II, powered by the 1.5L LYX turbocharged engine and equipped with an automatic transmission and all-wheel drive, represents a mid-cycle refresh of the second-generation Terrain (introduced in 2018). This variant aimed to broaden the Terrain’s appeal by offering a balance of fuel economy, respectable performance, and all-weather capability. Positioned as a mainstream trim level, it sat between the base models and the more powerful, often more expensive, engine options. The Terrain II, built on the GM Theta platform, was designed to compete with popular compact SUVs like the Honda CR-V, Toyota RAV4, and Ford Escape.

Powertrain & Engine Architecture

At the heart of this Terrain variant lies the 1.5L LYX inline-four cylinder engine. This engine utilizes direct injection and a single turbocharger with an intercooler to boost power and efficiency. The engine’s design incorporates a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT) to optimize performance across the rev range. The 9-speed Hydra-Matic automatic transmission is a key component, offering a wide range of gear ratios to maximize fuel economy and provide smooth acceleration. This transmission is known for its relatively quick shifts and ability to keep the engine in its optimal power band. The engine produces 173 horsepower at 5600 rpm and 275 lb-ft of torque between 2000 and 4000 rpm. The Start & Stop system further contributes to fuel savings by automatically shutting off the engine when the vehicle is stationary.

Driving Characteristics

The 1.5L turbo engine, while not delivering the outright acceleration of larger displacement engines, provides adequate power for everyday driving situations. The 9-speed automatic transmission is well-tuned to work with the engine’s torque curve, offering responsive shifts and minimizing turbo lag. Compared to higher-output Terrain models, this variant feels less eager to accelerate, but it offers a more relaxed and fuel-efficient driving experience. The AWD system provides enhanced traction in inclement weather conditions, making it a practical choice for regions with snow or rain. The gear ratios are optimized for highway cruising, allowing for comfortable and quiet long-distance travel. While not a sporty SUV, the Terrain 1.5L Turbo AWD offers a composed and predictable ride.

Equipment & Trim Levels

The 1.5L Turbo AWD Automatic Terrain typically came standard with features such as a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, keyless entry, a rearview camera, and a suite of driver-assistance technologies including automatic emergency braking and lane departure warning. Interior upholstery was generally cloth, with available upgrades to leatherette or leather depending on the specific sub-trim level (SLE, SLT, AT4). Optional extras included a larger touchscreen display, a premium audio system, a panoramic sunroof, heated and ventilated front seats, and adaptive cruise control. The dashboard layout was functional and modern, with a focus on ease of use.

Chassis & Braking

The Terrain II utilizes an independent suspension system, with a McPherson strut setup at the front and a multi-link suspension at the rear. This configuration provides a comfortable ride quality and decent handling characteristics. Front brakes are ventilated discs measuring 300mm, while rear brakes are solid discs measuring 288mm. The standard braking system is equipped with ABS (Anti-lock Braking System) to enhance safety and control during emergency stops. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering. The Terrain’s chassis is designed to provide a balance between ride comfort and handling stability.

Market Reception & Comparison

Critics generally viewed the 1.5L Turbo AWD Terrain as a competent and practical SUV, praising its comfortable ride, spacious interior, and user-friendly technology. However, some reviewers noted that the engine could feel underpowered when fully loaded or when climbing steep hills. Compared to the more powerful 2.0L turbo engine option, the 1.5L offered better fuel economy but less exhilarating performance. The 1.5L also provided a more affordable entry point into the Terrain lineup. In terms of reliability, the LYX engine has generally proven to be dependable, although some owners have reported minor issues with the turbocharger and fuel injectors. Fuel economy is rated around 25 mpg city and 30 mpg highway, making it competitive within its class.

Legacy

The GMC Terrain II 1.5L Turbo AWD Automatic has established itself as a popular choice in the used car market, offering a good balance of features, fuel efficiency, and affordability. The LYX engine, while not known for exceptional performance, has demonstrated reasonable long-term reliability. As these vehicles age, routine maintenance such as oil changes, timing chain inspections, and turbocharger health checks are crucial to ensure continued dependability. The Terrain II’s comfortable ride and spacious interior continue to appeal to buyers seeking a practical and versatile compact SUV.
