The 1.5L I-4 LSD is a turbocharged gasoline-powered engine produced by General Motors for use in small vehicles. Displacing 1.5 liters in an inline-four configuration, the LSD is part of a family of small displacement modular engines with direct injection. It replaces the outgoing turbocharged 1.5L I-4 LYX engine.
The LSD made its debut as the base engine in the 2023 Chevrolet Equinox and 2018 GMC Terrain where it makes 175 horsepower and 203 pound-feet of torque. The engine features a DOHC design, runs on gasoline (petrol) fuel and is force-inducted via a turbo-charger.
It’s worth noting that GM does not consider the LSD a “new” engine, with the only difference between it and the turbocharged 1.5L I-4 LYX being tweaks to improve combustion and emissions.
Notable engine features include:
- Gasoline-powered
- Dual Overhead Cam (DOHC) design
- Inline four-cylinder (I-4) configuration
- Variable Valve Timing (VVT)
- Turbo-charged
- Direct injected
TBD.
