The Chevrolet LNP is a 1,349 cc, inline — three turbocharged gasoline engine produced between 2020 and 2024. It features direct injection, dual overhead camshafts (DOHC), and continuously variable valve timing (VVT). In standard tune it delivers 155 hp (115 kW) and 184 lb — ft (250 Nm) of torque, offering responsive low — end pulling power and strong fuel efficiency for compact and subcompact applications.
Fitted to models such as the Trax, Trailblazer, and Sonic, the LNP w…
Production years 2020–2021 meet U.S. Tier 3 Bin 30 and Euro 6c; 2022–2024 models comply with Euro 6d-FINAL and EPA GHG Phase 2 (EPA File #EPA-GHG-2022-LNP).
The Chevrolet LNP is a 1,349 cc inline-three turbocharged gasoline engine engineered for compact and subcompact platforms (2020–2024). It combines direct fuel injection with a low-inertia turbocharger to deliver responsive low-RPM torque and smooth power delivery. Designed to meet U.S. Tier 3 and Euro 6d emissions standards, it balances performance with real-world efficiency.

The Chevrolet LNP was used across Chevrolet's Subcompact & Compact platforms with transverse mounting and utilised in GMC variants under shared GM architecture. This engine received platform-specific calibrations-shorter intake runners in the Trax and revised exhaust tuning in the Trailblazer-and from 2022 the updated Trailblazer models adopted enhanced turbo actuator sealing, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The LNP's primary reliability risk is turbocharger wastegate actuator binding on early builds, with elevated incidence in towing and hot climates. GM internal field reports from 2023 noted a significant number of pre-2022 engines requiring actuator replacement before 100,000 miles, while US EPA durability records highlight EGR cooler clogging in high-idle fleet vehicles. Frequent short trips and infrequent oil changes increase wear, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The LNP provides strong performance and good efficiency in compact and subcompact applications, but early models (2020-2021) had turbo wastegate actuator concerns. Later revisions (post-2022) improved component durability, so well-maintained examples can exceed 150,000 miles. Regular servicing and using correct oil (0W-20 GM Dexos1 Gen 2) are essential for longevity.
The most documented issues are turbo wastegate actuator binding (especially under load), intake carbon buildup from EGR, coolant leaks at the water pump, and fuel pump relay failure. These are confirmed in GM service bulletins and field reports from fleet operators.
The LNP was used in Chevrolet Trax and Trailblazer (2020-2024), as well as the Sonic (2021-2024). It was also available in GMC Tracker models under GM's shared architecture. All meet U.S. Tier 3 Bin 30 and Euro 6d emissions standards.
Yes, but with limitations. ECU tuning can yield modest gains (~20-30 hp) by optimizing boost and timing maps. However, the stock turbo and fuel system limit high-RPM potential. Supporting mods like intercooler and exhaust help, but significant power increases require internal upgrades.
Excellent for a turbo-three. In a Trax, expect ~27 mpg (8.7 L/100km) city and ~34 mpg (6.9 L/100km) highway. Real-world mixed driving typically yields 30-32 mpg (7.8-7.3 L/100km). Fuel economy depends heavily on load, towing, and driving style.
Yes. The LNP is an interference engine. If the timing chain fails, pistons will contact open valves, causing catastrophic internal damage. Timing chain maintenance and using correct oil are critical to prevent failure.
GM specifies 0W-20 synthetic oil meeting GM Dexos1 Gen 2 specification. This oil is critical for turbo bearing and timing chain protection. Change intervals should not exceed 10,000 miles or one year, whichever comes first, especially in severe service conditions.
