2018-2021 Chevrolet Silverado 1500 IV Crew Cab Short Box 2.7 Turbo (310 Hp) Automatic

The Chevrolet Silverado 1500 IV Crew Cab Short Box 2.7 Turbo, produced from 2018 to 2021, represented a significant entry point into the fourth generation of Chevrolet’s full-size pickup truck line. Positioned as a more fuel-efficient alternative to the larger V8 engines offered in the Silverado 1500 range, this variant aimed to attract buyers prioritizing everyday usability and towing capacity without the higher running costs. It was a key component of Chevrolet’s strategy to broaden the Silverado’s appeal in a competitive segment, offering a blend of capability and affordability. This model utilized the 1HX0 platform, shared with the GMC Sierra.

Technical Specifications

Powertrain & Engine Architecture

The heart of this Silverado variant is the GM L3B 2.7-liter turbocharged inline-four engine. This engine, introduced in 2018, represented a departure from the traditional V6 and V8 options typically found in full-size trucks. It utilizes direct injection and a twin-scroll turbocharger to deliver 310 horsepower and 473 lb-ft of torque. The engine features a cast aluminum block and cylinder head, contributing to weight savings. Variable valve timing (VVT) and direct injection optimize combustion efficiency and power delivery. The engine is paired with an eight-speed Hydra-Matic automatic transmission, chosen for its smooth shifting and wide gear ratio spread. This transmission is designed to maximize fuel efficiency while providing adequate power for towing and hauling. The L3B also incorporates Active Fuel Management (cylinder deactivation) to further improve fuel economy during light-load driving conditions.

Driving Characteristics

The 2.7-liter turbo engine provides a surprisingly capable driving experience for a full-size pickup. While not as immediately powerful as the larger V8 engines, the turbocharger provides a broad torque curve, making it well-suited for everyday driving and towing. The eight-speed automatic transmission helps keep the engine in its optimal power band, delivering responsive acceleration. Compared to the 5.3L V8, the 2.7T offers less outright power, but its lighter weight and efficient turbocharging contribute to better fuel economy. The gear ratios are tuned for both towing and highway cruising, providing a comfortable and controlled ride. The 2.7T Silverado doesn’t offer the same level of performance as its V8 siblings, but it provides a more refined and economical driving experience.

Equipment & Trim Levels

The 2.7 Turbo engine was available across several Silverado 1500 trim levels, including the LS, LT, RST, and Trail Boss. Standard equipment typically included air conditioning, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a rearview camera. Higher trim levels added features such as leather upholstery, heated and ventilated seats, a premium sound system, and advanced safety technologies like lane departure warning and automatic emergency braking. The Crew Cab configuration offered ample passenger space, making it a practical choice for families. Optional extras included a power sunroof, a navigation system, and a trailering package.

Chassis & Braking

The Silverado 1500 IV utilizes a fully boxed frame constructed from high-strength steel, providing a solid foundation for the vehicle. The front suspension features independent coil springs, while the rear suspension employs a traditional leaf spring setup. This configuration balances ride comfort with load-carrying capacity. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) is standard. The 2.7T models generally featured slightly softer suspension tuning compared to the heavier V8-powered trucks, prioritizing ride comfort. Stabilizer bars were included to reduce body roll during cornering.

Market Reception & Comparison

The 2.7-liter turbo Silverado received generally positive reviews, with critics praising its fuel efficiency and surprisingly strong performance. It was often seen as a compelling alternative for buyers who didn’t require the maximum towing capacity of the V8 models. Compared to the 5.3L V8, the 2.7T offered significantly better fuel economy, particularly in city driving. However, some reviewers noted that the engine could feel strained when towing heavy loads. Reliability reports have been mixed, with some owners reporting issues with the turbocharger and fuel system. Overall, the 2.7T Silverado offered a good balance of capability, comfort, and affordability.

Legacy

The 2.7-liter turbo engine has become a mainstay in the Chevrolet Silverado 1500 lineup, undergoing several revisions and improvements over the years. The initial L3B engine proved to be a capable and efficient powerplant, paving the way for future turbocharged engine options in Chevrolet trucks. On the used car market, the 2018-2021 Silverado 1500 2.7 Turbo represents a good value proposition, offering a well-equipped and capable pickup truck at a competitive price. While long-term reliability remains a consideration, the engine’s relatively simple design and readily available parts contribute to its maintainability. The 2.7T Silverado demonstrated Chevrolet’s commitment to offering a wider range of powertrain options to meet the diverse needs of truck buyers.
