The GMC Acadia Denali is poised to receive a few equipment-level adjustments for the 2021i (2021 interim) model year. One of the more critical changes will be new availability for the turbocharged 2.0L I4 LSY gas engine, GM Authority has learned.
The turbo 2.0L I4 LSY was added to the GMC Acadia lineup for the 2020 model year as an option on SLE trim levels, as well as standard equipment on SLT trim levels. Now, the engine will be a free-flow option (that is, unrestricted by any package) on the latest 2021i GMC Acadia Denali.
The turbo 2.0L engine will be available on both FWD and AWD powertrains for the 2021i GMC Acadia Denali, and will mate to the nine-speed automatic transmission. Order books for the 2021i GMC Acadia opened late last month, while orders for 2021i GMC Acadia Denali with the turbo 2.0L LSY are slated for late availability.
Meanwhile, the GMC Acadia Denali will continue to offer the naturally aspirated 3.6L V6 LGX gas engine as standard equipment.
For those who are confused as to why customers may want opt for the turbo 2.0L I4 LSY over the standard 3.6L V6 LGX gas engine, the reasoning comes down to two things – fuel economy, and low-end torque.
Compared to the LGX, the LSY offers better fuel returns, with 22 mpg in the city, 29 mpg on the highway, and 25 mpg combined, as compared to the 19 mpg in the city, 27 mpg on the highway, and 22 mpg combined ratings for the V6 engine. Note that the ratings listed in here are for models equipped with FWD.
What’s more, the turbo four-cylinder makes peak torque (258 pound-feet) between 1,500 and 4,000 rpm, whereas the V6 needs to spin to 5,000 rpm to make its peak torque figures (271 pound-feet).
