Reviews Summary

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.

Reviews Summary

The small, lumpy i3 hatchback may not look like a BMW underneath all of its badges and grilles, but it does have enough tech to make up for it. A carbon fiber and aluminum body, and lightweight materials inside, help a 22kWh battery power the i3 for 80 miles on electricity alone—when fitted with an optional "range extending" gas-powered generator, twice that. Its $42,400 entry price isn't for the squeamish, but the "gee-whiz" tech helps make up for that.
