The GM turbocharged 2.0L inline four-cylinder LSY gasoline engine is currently in use in a variety of different GM vehicles and brands, and now, GM Authority has learned that a higher-output variant of the LSY engine could be in the works.
According to sources familiar with the matter, GM may develop a new variant of the turbocharged 2.0L I4 LSY gasoline engine producing not only more horsepower, but more torque as well, with twist topping out at around 290 pound-feet, as compared to the 258 pound-feet produced by the current engine variant. To note, the LSY currently produces 228 horsepower, 235 horsepower, or 237 horsepower, depending on the application.
In addition to producing more power and torque, this higher-output variant of the LSY engine may also produce slightly higher emissions.
For those readers who may be unaware, the GM turbocharged 2.0L inline four-cylinder LSY gasoline engine gradually replaced the turbocharged 2.0L I4 LTG engine previously used in various GM products. Compared to the LTG, the LSY is less powerful, but is more refined and runs cleaner (lower emissions). For example, under the hood of the Cadillac ATS, the LTG is rated at 272 horsepower and upwards of 295 pound-feet of torque, as compared to the LSY’s 237 horsepower and 258 pound-feet of torque.
Just a few applications for the turbocharged 2.0L inline four-cylinder LSY gasoline engine include the Cadillac XT4, GMC Acadia, Cadillac XT5, Cadillac XT6, Cadillac CT5, Cadillac CT4, and Chevy Blazer.
Although four-cylinder engines were at one time considered “underpowered” for certain applications, modern internal combustion technology has made the configuration appropriate for a wide range of segments. One good example of this is the GM 2.7L I4 L3B gasoline engine, which recently got a substantial torque boost to a peak of 430 pound-feet. Under the hood of light-duty pickups like the 2022 Chevy Silverado 1500 and 2022 GMC Sierra 1500, the L3B is more than up to the task when it comes to all the usual pickup truck activities.
