Cadillac CT5 vs BMW 5 Series

The BMW 5 Series is one of three cars that prove the country known for Autobahns, the Nürburgring, and Oktoberfest builds the best luxury sedans on the planet. It competes with the Audi A6 and Mercedes-Benz E-Class, each taking a distinct approach to design but measuring up closely in other parameters. The 2026 5 Series is virtually unchanged, entering its third year following a 2024 redesign, and this review is about the 540i xDrive model.

Verdict: Putting BMW’s love-it-or-hate-it design aside, the 2026 540i xDrive is a sensational automobile offering the right blend of luxury, technology, and performance. Choose the M Sport setup for maximum driving enjoyment, or stick with the standard specification to emphasize luxury. Either way, the styling is the most controversial thing about the 5 Series.

A relative bargain in the premium midsize car segment, the 2025 CT5 sedan receives several changes to keep it appealing. Mostly, they pertain to technology, and the new 33-inch display containing digital instrumentation and a new infotainment system is the most obvious manifestation of that. In addition, the CT5 gets more standard and available safety features and driver assistance tech, AKG audio, new front-end styling, and a couple of new paint colors.

Verdict: Despite the updates for 2025, the Cadillac CT5 is starting to look and feel like an older car. Also, compared to its rivals, it lacks polish and refinement. However, it is a bargain when cross-shopping it with the Audi A6, BMW 5 Series, and Mercedes-Benz E-Class. Its tech is impressive, too.
