GM Authority has learned GM is considering the introduction of a new GMC Acadia turbo with the arrival of the next-generation crossover, which is expected to go on sale as a 2024 model year product. This model could offer more performance than lesser GMC Acadia models with smaller engines, given the L3B engine’s relatively high power and torque outputs, and could even replace the 3.6L LGX V6.
The Acadia turbo’s arrival would be the first time the turbocharged 2.7L I4 L3B engine would be mounted transversely in a front-wheel-drive based product. This engine is already utilized in the Cadillac CT4 and Cadillac CT4-V, as well as the Chevy Silverado 1500 and GMC Sierra 1500, which are all rear-wheel-drive based vehicles with longitudinally-mounted engines.
The 2.7L L3B engine is sold in different states of tune, depending on which GM product it’s used in. For example, this engine produces 310 horsepower and 350 pound-feet of torque in the regular Cadillac CT4, but produces 325 horsepower and 380 pound-feet of torque in the performance-minded CT4-V. In the latest 2022 Chevy Silverado 1500 and GMC Sierra 1500, this engine is rated at 310 horsepower and 430 pound-feet of torque, with the higher torque figure aiding in hauling and towing performance for these two full-size trucks. It’s not clear how much power it would make in the rumored Acadia turbo.
The next-generation GMC Acadia is expected to grow in length, as GM Authority reported previously, with this future model set to be roughly the same size as the current Chevrolet Traverse and Buick Enclave. While front-wheel drive will be standard in this upcoming crossover, we expect all-wheel drive to be offered as an option.
GM Authority spies captured photos of a next-gen Acadia prototype testing on public roads this past winter, revealing the crossover’s larger stature and boxier apparent shape.
