Rate this article Choose 1-5 stars.

Introduction

The 2020 GMC Sierra 2WD is a full-size, rear-wheel-drive pickup from GMC’s “professional grade” lineup, aimed at buyers who want a standard (full-size) truck for work, towing, and everyday driving without paying the fuel and purchase-price penalty of 4WD. In 2020, the Sierra 1500 continues the modern, squared-off styling and feature-rich approach introduced with this generation, pairing a broad trim walk with strong trailering tech and a wide spread of comfort and convenience options.

Design and Exterior Features

The Sierra’s exterior design leans bold and upright, with a tall hood line, broad grille treatments that change by trim, and a long, planted stance that clearly communicates “standard pickup truck.” In 2WD form it keeps a clean, road-focused posture while still offering the bed utility and tailgate innovations that helped this generation stand out. Compared with earlier Sierra designs, the newer body style looks sharper and more sculpted, and it emphasizes functional upgrades such as more available camera views and a highly configurable tailgate on higher trims.

Large, trim-specific grille designs with a squared, modern front-end look
Multiple bed lengths and cab choices depending on configuration
Available MultiPro tailgate on higher trims for easier loading and worksite flexibility
Available trailering-focused camera systems (varies by trim/packages)

Interior and Comfort

Inside, the 2020 Sierra focuses on straightforward controls, practical storage, and a range of finishes from work-truck simple to near-luxury in upper trims. The cabin layout is built around daily usability: large knobs and buttons, clear sight lines, and comfortable seating for long drives. Materials and ambiance vary widely by trim; entry models prioritize durability, while trims like SLT, AT4, and Denali layer in upgraded surfaces, more sound insulation, and additional comfort features that can make the Sierra feel more premium than many traditional work-oriented pickups.

Spacious front seating and a wide, truck-appropriate driving position
Available heated and ventilated front seats on higher trims
Available dual-zone climate control (trim/package dependent)
Practical storage throughout the cabin for tools, devices, and small cargo

Performance and Handling

This 2020 GMC Sierra 2WD configuration uses a 4.3L EcoTec3 V6 gasoline engine with direct injection and Active Fuel Management, paired with a 6-speed automatic transmission and rear-wheel drive. Output for this V6 is rated at 285 hp and 305 lb-ft of torque. On the road, the Sierra’s size is always present, but steering and braking feel predictable for the class, and the 2WD setup can feel lighter and more responsive than comparable 4WD models in daily driving. Fuel economy for the 2WD regular-cab V6/6-speed configuration is EPA-rated at 17 mpg combined (16 city/21 highway), which is about 13.8 L/100 km combined (about 14.7 city / 11.2 highway). Acceleration varies significantly by cab/bed weight and axle ratio, so it’s best judged by configuration-specific tests rather than assuming one universal number.

Engine: 4.3L EcoTec3 V6 (direct injection) with Active Fuel Management
Power: 285 hp; torque: 305 lb-ft
Transmission: 6-speed automatic
Fuel economy (EPA, specific configuration): 17 mpg combined (about 13.8 L/100 km)

Technology and Connectivity

The 2020 Sierra’s tech offering ranges from basic but modern essentials to advanced trailering and luxury features. Even the base truck can be equipped with an infotainment touchscreen and modern smartphone integration, while upper trims expand to larger screens, premium audio, more USB coverage, wireless charging, and a broader suite of camera views that are especially useful when towing or maneuvering in tight spaces.

Bluetooth connectivity and available in-vehicle Wi-Fi hotspot
Available upgraded audio systems on higher trims

Safety Features

Safety equipment on the 2020 Sierra varies by trim and options, but common modern features like a rearview camera are widely available, and advanced driver-assistance systems can be added on many versions. In IIHS testing for the Sierra 1500, front crash prevention (vehicle-to-vehicle) is available as an optional system and earned a Superior rating, while headlight performance on tested configurations was rated Poor. NHTSA overall star ratings can vary by configuration; published summaries commonly report an overall 4-out-of-5-star result for the 2020 Sierra 1500 family, so shoppers should confirm ratings for their exact cab and drivetrain configuration.

Available forward collision alert and automatic emergency braking (availability depends on trim/packages)
Available blind-spot monitoring and lane-departure warning/lane-keep assist (availability depends on trim/packages)
IIHS: optional front crash prevention system rated Superior (vehicle-to-vehicle)
IIHS: headlight ratings on tested configurations rated Poor

Pricing and Variants

Pricing for the 2020 GMC Sierra 2WD depends heavily on cab, bed length, and trim. For example, a 2020 Sierra 1500 regular-cab long-box 2WD configuration is listed with a base MSRP around $29,195, while other body styles and higher trims climb quickly as equipment and capability increase. The Sierra is offered in multiple trims, commonly including Base (Sierra), SLE, Elevation, SLT, AT4, and Denali, each targeting a different mix of work, comfort, and off-road emphasis. In the standard full-size 2WD pickup category, key competitors include the Ford F-150, Ram 1500, and Chevrolet Silverado 1500; the Sierra differentiates itself with its upscale trim ladder, distinctive styling, and a strong menu of trailering and camera technology.

Summary

The 2020 GMC Sierra 2WD is best suited for drivers who want full-size pickup capability for hauling, towing, and daily usability, and who prefer a rear-wheel-drive setup for lower complexity and often lower cost than 4WD.

As a value proposition, it’s a compelling choice when matched carefully to the right cab/bed/trim and equipped with the safety and tech features you actually want, while keeping realistic expectations about big-truck operating costs and the importance of configuration-specific reliability history.
