BMW M5 vs Audi S5

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.

Updated and mostly upgraded, the redesigned Audi S5 is a multi-talented sportback with performance, comfort, utility, and the latest technology. Based on the redesigned Audi A5, it features a stealthy design, thrilling dynamics, and just enough room for a family of four. The new Audi Digital Stage technology impresses, but the driving assistance systems do not. The S5 could also use sharper styling with more prominent fender blisters and additional sound deadening for a quieter highway ride.

Verdict: Drive a new 2025 Audi S5 like a typical luxury sedan, and you’ll miss the point. We didn’t fall in love with it until we took it for a rousing run on a favorite back road. If that’s not your thing, consider the new A5 or the larger A6, which is getting redesigned for the 2026 model year.
