The percentage of mid-size luxury SUVs with four-cylinder gasoline turbo engines has doubled in the last five years in the U.S. automotive industry. That’s according to data shared by General Motors during a recent presentation to dealers, seen by GM Authority.
GM is no stranger to this development, as it has begun to offer its turbocharged 2.0L I4 LSY engine in more luxury SUVs (technically crossovers) than ever before.
The LSY became available as an alternative to the naturally aspirated 3.6L V6 LGX engine in the 2020 GMC Acadia Denali as part of that model’s refresh / mid cycle enhancement. At 310 horsepower and 271 pound-feet of torque as fitted to the Acadia, the LGX is more powerful, but versions fitted with the LSY have a slightly lower MSRP, as GM Authority exclusively reported earlier this month.
The LSY was also added to the 2020 Cadillac XT5, and is now the base engine in the Luxury and Premium Luxury trim levels. The LGX is an option only the Premium Luxury model, while being standard on the Sport trim level.
There is a similar story with the XT6, though the change took place a year later. In its first model year, the 2020 Cadillac XT6 was available only with the LGX engine, but the 2021 Cadillac XT6 acquired a new base trim level called Luxury, as per Cadillac’s Y trim level strategy. The Luxury trim is available exclusively with the LSY turbo engine, though the LGX remains the only engine fitted to models in the more expensive Premium Luxury and Sport trim levels.
|Vehicle/Engine||Peak Power (hp)||Peak Torque (lb-ft)|
|Cadillac XT5 2.0L LSY||235||258|
|Cadillac XT5 3.6L LGX||310||271|
|Cadillac XT6 2.0L LSY||235||258|
|Cadillac XT6 3.6L LGX||310||271|
|GMC Acadia 2.0L LSY||228||258|
|GMC Acadia 3.6L LGX||310||271|
It’s worth noting that the XT5 and XT6 situation applies only to North American markets. In China, the LSY engine is standard on both models through the trim range.
In addition to the vehicles mentioned above, the LSY is also standard or available in the Buick Envision, Cadillac XT4 and Chevy Blazer crossovers, and in the Cadillac CT4 and Cadillac CT5 luxury sedans. It made its debut in the 2019 Cadillac XT4 and has replaced the last-gen 2.0L I4 LTG in all models but two: the Chevy Malibu (where it serves as the up-level engine) and Camaro (where it serves as the base engine).
