BMW 5 Series vs BMW M5

Now a plug-in hybrid, the redesigned 2025 BMW M5 is a versatile, high-performance sedan that allows drivers to have their cake and eat it, too. It may put out 717 horsepower—and certainly feels like it—but the M5’s repertoire also includes a calming all-electric driving experience for up to 25 miles, which also makes this version the most efficient M5 ever.

Verdict: The new BMW M5 boasts impressive speed, agility, and daily usability. It's not perfect; the exhaust is too quiet for a performance vehicle and its ride is too harsh for a luxury car. But for the shopper who wants a sedan capable of doing a bit of everything, the M5 delivers in excess.

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.
