BMW M5 vs BMW 5 Series

One of the most hallowed names in BMW lore, the M5 is a high-performance version of the midsize 5 Series with extensive powertrain upgrades to suit the racetrack and autobahn alike. The M5 underwent what is arguably its most extensive redesign ever for the 2025 model year, switching to the current-generation 5 Series body (known as the G60) and gaining a first-ever plug-in hybrid powertrain. As such, changes for 2026 are limited to a more powerful onboard charger and more paint options.

Verdict: Today’s M5 is unrecognizable from previous generations, but still a compelling performance car.

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.
