Technical Specifications

Introduction

The 2018-2021 Chevrolet Silverado 1500 Crew Cab with the 2.7-liter turbocharged four-cylinder engine and four-wheel drive automatic transmission represented a strategic move by Chevrolet to offer a more fuel-efficient and accessible option within its popular full-size truck range. This configuration was positioned as the entry-level powertrain for the Crew Cab body style, appealing to buyers who prioritized everyday usability and lower running costs over outright towing capacity or high-performance acceleration. Built on the second iteration of the K2XX platform, the Silverado IV aimed to improve upon its predecessor with increased interior space, enhanced materials, and a suite of new technologies.

Powertrain & Engine Architecture

At the heart of this Silverado variant lies the GM L3B 2.7-liter turbocharged inline-four engine. This engine utilizes direct injection and variable valve timing (VVT) to optimize both power and efficiency. The L3B is a relatively compact engine, allowing for easier packaging within the Silverado’s engine bay. The turbocharger, coupled with an intercooler, provides a significant boost in power and torque compared to naturally aspirated engines of similar displacement. The engine is paired with an eight-speed Hydra-Matic automatic transmission, which is known for its smooth shifting and wide gear ratio spread. This transmission helps to keep the engine operating in its optimal power band, maximizing both performance and fuel economy. The engine also features Active Fuel Management (cylinder deactivation) to further improve fuel efficiency during light-load driving conditions.

Driving Characteristics

The 2.7-liter turbo engine delivers a respectable 310 horsepower and 473 lb-ft of torque, providing adequate power for most everyday driving situations. While not as quick as the V8-powered Silverado models, the 2.7T offers a surprisingly responsive driving experience, with the turbocharger providing a noticeable surge of power. The eight-speed automatic transmission contributes to smooth and efficient gear changes. Compared to the larger 5.3L or 6.2L V8 engines, the 2.7T Silverado feels less powerful during acceleration and towing. However, the lower weight of the engine contributes to improved handling and a more comfortable ride. The 4WD system provides enhanced traction in inclement weather and off-road conditions, making it a versatile vehicle for a variety of uses.

Equipment & Trim Levels

The 2.7 Turbo 4WD Automatic was typically offered in lower to mid-range Silverado trim levels, such as the LS, LT, and RST. Standard features generally included air conditioning, a basic infotainment system with a touchscreen display, Bluetooth connectivity, and a rearview camera. Higher trim levels added features such as leather upholstery, heated seats, a premium sound system, and advanced safety technologies like lane departure warning and automatic emergency braking. Optional extras included a larger touchscreen display, navigation, a sunroof, and various appearance packages.

Chassis & Braking

The Silverado 1500 IV utilizes a fully boxed frame for increased rigidity and strength. The front suspension features independent coil springs, while the rear suspension employs a traditional leaf spring setup. This configuration provides a good balance between ride comfort and load-carrying capacity. Braking duties are handled by ventilated disc brakes on all four wheels. ABS (Anti-lock Braking System) is standard. The rear axle ratio varies depending on the specific configuration, impacting both fuel economy and towing capacity.

Market Reception & Comparison

The 2.7-liter turbo Silverado received mixed reviews from automotive critics. While praised for its fuel efficiency and smooth ride, some reviewers found its power output to be lacking compared to the V8 options. Compared to the 5.3L V8, the 2.7T offered significantly better fuel economy, but less towing capacity. The 2.7T was often seen as a good choice for buyers who primarily used their trucks for commuting and light-duty tasks, while the V8 models were preferred by those who needed to tow heavy loads or engage in more demanding work. Reliability reports have generally been positive, with the L3B engine proving to be a relatively durable and dependable powerplant.

Legacy

The 2.7-liter turbocharged four-cylinder engine has become a mainstay in the Chevrolet Silverado lineup, demonstrating its viability as a fuel-efficient and capable option for full-size truck buyers. The 2018-2021 Silverado 1500 2.7T 4WD Automatic remains a popular choice in the used car market, offering a compelling combination of value, practicality, and modern features. Its relatively simple engine design and readily available parts contribute to its long-term reliability and affordability, making it a sensible option for those seeking a dependable and versatile pickup truck.
