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 it’s still a compelling performance car.

The S5 is the performance version of the A5, a compact luxury car equipped with a handy Sportback design that offers more utility than a traditional three-box sedan. With the 2026 S5, Audi attempts to right some technological wrongs, returning familiar controls to the car while introducing an all-new Multi Media Interface (MMI) infotainment system with AI-enhanced voice controls.

Verdict: Dull design and distracting technology are the trade-offs for the 2026 Audi S5’s thrilling dynamics and daily driver practicality. Nevertheless, the stealthy anonymity draws from a classic German sports sedan recipe, and buyers can choose not to use certain features.
