$44,400 · Sedan

$47,500 · Sedan

Comparison Overview

The 2025 Mercedes-Benz CLA-Class explodes onto the scene dripping with avant-garde style, aiming to capture hearts with its sleek, coupe-like silhouette and an accessible $44,400 MSRP. However, the 2026 BMW 3 Series brings raw, time-tested driving mastery, boasting a potent 255 hp and 295 lb-ft of torque compared to the CLA's 221 hp. The Bimmer offers superior utility with a generous 16.9 cu ft of cargo space versus the CLA’s snug 11.6 cu ft, making the Mercedes less practical for family hauling. While both demand premium unleaded fuel, the 3 Series nets a slight efficiency edge with 31 combined MPG versus the CLA’s 30. Furthermore, the BMW's fundamental Rear Wheel Drive platform promises a more engaging handling dynamic, distancing itself from the CLA's standard Front Wheel Drive setup, even with a $3,100 higher entry price.
