BMW M5 vs Audi S5

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.

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.
