BMW’s next-generation 3 Series is inching ever closer to production, and with a November 2026 launch on the horizon, the puzzle pieces are starting to fall into place. While much of the hype centers on the Neue Klasse–inspired exterior and a high-tech interior brimming with digital wizardry, the real story lies under the hood.
Sources indicate that BMW is readying the B48TÜ3, the latest evolution of its venerable 2.0-liter turbocharged four-cylinder engine. This unit will form the backbone of the upcoming 320, 330, and 330e models, combining efficiency and performance for everyday drivers. At the top of the lineup, a revised six-cylinder—the B58TÜ3—will power the next M350, continuing BMW’s tradition of inline-six excellence. For context, the B58TÜ3 will make its debut in the G70 7 Series LCI next July, delivering 286 horsepower and 295 lb-ft in the 735, and a hefty 400 horsepower and 400 lb-ft in the 740. It’s clear this same engine will anchor the sportier M-badged 3 Series replacement.
Early spy shots from 2025 offer a tantalizing glimpse at the G50’s exterior. Even beneath heavy swirly camouflage, the Neue Klasse design language is unmistakable. The grille stretches wider, seamlessly merging with slimmer, laser-like headlights that echo the Vision Neue Klasse concept as well as the upcoming BMW i3. While these lights may still be prototype hardware, the overall shape is expected to carry over to production largely unchanged.
The hood remains long enough to accommodate the six-cylinder engine, which aligns with BMW’s confirmation that the next M3 will retain an inline-six layout. Along the sides, flush door handles and clean, minimalist surfaces signal BMW’s move toward more understated forms. At the rear, temporary taillights obscure many details, but subtle refinements and thinner lighting signatures are visible, complemented by a discreet integrated spoiler. Notably, visible exhaust tips will become increasingly rare outside of M Performance and M models, as BMW shifts toward cleaner aesthetics.
Electrification continues to shape the lineup, with the fully electric i3 (NA0) sharing the same overall silhouette as its gasoline counterpart, save for a shorter front overhang. As BMW design chief Adrian van Hooydonk noted earlier this year, distinguishing ICE from EV models will soon come down to subtle proportions rather than radical styling differences.
Production plans are already in motion: the G50 3 Series sedan is expected to be built in Dingolfing, while the NA0 i3 electric sedan and the NA1 electric wagon will roll out of Munich. Both ICE and EV variants are slated to begin production simultaneously in November 2026, marking a significant milestone in BMW’s dual-path strategy.
With a Neue Klasse aesthetic, high-tech cabin, and a refreshed engine lineup, the next-generation 3 Series promises to honor its legacy while embracing the future—sporty, efficient, and unmistakably BMW.
