The subsequent-generation BMW 3 Sequence is deep into growth, and the nearer it will get to its November 2026 manufacturing begin, the extra items of the puzzle come collectively. Beyond the Neue Klasse-inspired design and high-tech inside, the largest information considerations the engine household powering the gasoline and plug-in hybrid fashions. In accordance with insiders, BMW is getting ready a rollout of the B48TÜ3, the latest evolution of its 2.0-liter turbo four-cylinder, which is able to function the spine of the 320, 330, and 330e. And sitting on the high of the lineup will likely be a revised six-cylinder: the B58TÜ3.
We already reported on the B58TÜ3 debuting within the G70 7 Sequence LCI subsequent July—within the 735 with 286 horsepower and 295 lb-ft, and the 740 with an excellent 400 horsepower and 400 lb-ft. Now it’s clear the identical era of engine will ultimately energy the alternative for the M340i: the upcoming BMW M350.
However earlier than we get there, right here is every part we all know up to now concerning the G50 3 Sequence lineup and the engines that can outline it.
A Nearer Have a look at the G50 Prototypes
When we published early spy shots in 2025, the prototype in query gave us an early take a look at the outside design. Even with the acquainted swirly camouflage, the Neue Klasse affect is not possible to overlook. The broader, extra horizontal kidney grille blends into slimmer headlights, echoing the Imaginative and prescient Neue Klasse idea and the upcoming BMW i3. These headlights should still be prototype-spec, however the general form is anticipated to achieve manufacturing unchanged.
The hood stretches lengthy sufficient to maintain choices open for six-cylinder fashions, which aligns with BMW’s affirmation that the next-generation M3 will continue with an inline-six configuration. Alongside the perimeters, flush door handles and a cleaner floor remedy trace at BMW’s shift towards less complicated kinds.
On the rear, non permanent taillights conceal most particulars, however the normal proportions counsel a barely extra refined look with thinner lighting signatures. A discreet built-in spoiler extends from the trunk lid. As BMW pushes for cleaner, extra minimal designs, the times of uncovered exhaust pipes are dwindling—solely M Efficiency and M fashions will retain seen ideas.
Gasoline and Electrical Will Look Practically Similar
The absolutely electrical i3 (NA0) will share the identical general form as its G50 gasoline sibling, save for a noticeably shorter entrance overhang. Adrian van Hooydonk instructed us earlier this yr that distinguishing ICE from EV fashions will likely be more and more troublesome. The core differentiation would be the nostril size—devoted EVs merely don’t want the packaging house for an engine.
BMW plans for each the G50 3 Sequence and NA0 i3 to enter manufacturing on the identical time in November 2026. The i3 has already been confirmed for Munich, however the subsequent 3 Sequence sedan will nearly definitely migrate to Dingolfing, with the electric wagon NA1 following shortly after in Munich.
