BMW M3 vs Audi S5

For six generations, the BMW M3 sedan has long exemplified everyday-friendly high-performance, and for 2025, its current G80 generation possesses a handful of exterior and tech mid-cycle updates to keep the formula fresh. It’s what brand enthusiasts refer to as the LCI model, or, life-cycle impulse.

Since 2021, the M3 been offered in either standard or Competition trims, xDrive all-wheel drive (AWD) or rear-wheel drive (RWD), and with either a six-speed manual or eight-speed automatic transmission. The Bavarian brand maintains its inline-six engine layout—a cornerstone of its history—and there’s no hybrid assistance to be found; just two mono-scroll turbochargers to help produce thrilling acceleration all over the rev band.

Verdict: There are few purpose-built-yet-all-purpose vehicles on the road that offer the same thrills as BMW’s most iconic four-door performance badge.

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. Complimentary scheduled maintenance is a new ownership perk, too.

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.
