2025 Buick Enclave vs 2025 Mercedes-Benz GLA-Class
Comparison Overview
The 2025 Buick Enclave charges forward with a commanding presence, boasting 328 horsepower, making it the undisputed power player in this matchup, far outstripping the Mercedes-Benz GLA-Class's 221 horsepower. This nearly foot-and-a-half difference in length (207.6 inches vs. 173.6 inches) translates directly into massive utility, offering 22.9 cu ft of cargo space compared to the GLA’s tight 15.4 cu ft. However, the nimble GLA compensates with efficiency, achieving a phenomenal combined 29 MPG using regular unleaded fuel, while the Enclave settles for 23 MPG combined, even though both require FWD. While the GLA starts slightly cheaper at $43,000, the Enclave delivers 107 more horsepower and superior size, presenting a compelling trade-off between outright power/space and fuel thriftiness.
