$39,600 · Coupe

$35,600 · Sedan

Comparison Overview

Deciding between premium German handling and sharp American luxury often boils down to budget versus pure driving engagement. If you're looking at the 2025 BMW 2 Series ($39,600 MSRP) and the 2026 Cadillac CT4 ($35,600 MSRP), you are looking at two excellent rear-wheel-drive options, but they serve slightly different priorities. The BMW offers a tangible performance edge with 255 horsepower and 295 lb-ft of torque, feeling punchier than the CT4's 237 hp. However, the BMW demands a $4,000 higher initial outlay and requires premium fuel, while the Cadillac is content with recommended premium fuel. Surprisingly, the smaller BMW coupe (179.0 inches long) boasts better fuel economy at 30 combined MPG versus the longer CT4 sedan (187.2 inches) at 26 combined MPG. While the BMW is quicker and slightly more efficient, the CT4 offers a more practical sedan body and saves you cash upfront, making the final choice a classic trade-off between sporty dynamics and practicality.
