$43,995 · Sedan

$35,600 · Sedan

Comparison Overview

The 2025 Alfa Romeo Giulia ignites the senses with 280 hp surging through its rear-wheel-drive chassis, demanding attention with Italian flair. In contrast, the 2026 Cadillac CT4 offers accessible luxury, grounded by a slightly more conservative 237 hp output from its premium-recommended powertrain. The Giulia boasts superior performance metrics, delivering 43 more horsepower and 48 lb-ft more torque than the CT4. However, this excitement comes at a cost, evidenced by the Giulia's MSRP of $43,995 versus the CT4's starting price of $35,600, representing an $8,395 gap. While both sedans offer similar efficiency, achieving a combined 27 MPG (Giulia) versus 26 MPG (CT4), the Alfa commits you to required premium fuel, whereas Cadillac recommends it. The decision boils down to prioritizing raw, emotional power versus pragmatic, cost-conscious elegance in this dynamic duo of American and Italian rear-drive sport sedans.

The difference is substantial, with the Giulia producing 280 hp compared to the CT4's 237 hp—a 43 hp advantage for the Alfa. This results in noticeably sharper acceleration from the Giulia when pushing hard.

Is the higher price of the Alfa Romeo Giulia justified by better fuel economy?

Not significantly; the Giulia achieves 27 MPG combined, while the CT4 is right behind at 26 MPG combined. The $8,395 price increase does not translate into substantial fuel savings.

Which car is better suited for a driver focused on minimizing running costs?

The Cadillac CT4 is the winner here; its lower MSRP of $35,600 immediately saves money, and its fuel requirement is only recommended premium, unlike the Giulia's mandatory premium unleaded.

How do the physical dimensions impact daily usability?

The CT4 is nearly 5 inches longer overall (187.2 inches vs. 182.5 inches) but slightly narrower, offering 10.7 cu ft of trunk space. The Giulia's smaller size might translate to slightly better maneuverability in tight city parking scenarios.

Despite similar mechanical foundations, the Giulia’s 306 lb-ft of torque paired with its performance-tuned chassis offers a more immediate and tactile experience favored by enthusiasts, while the CT4's setup leans toward refined composure.
