The next generation of the German sports sedan arrives in 2026 with radical design, new tech, and a split ICE and EV lineup
Update: A lot has happened since we last looked at the future G50 3 Series. Thanks to new renderings, fresh intel, and the latest spy shots, we now have the clearest picture yet of how Munich’s defining sports sedan is set to evolve in its next generation.
Sedans may no longer dominate sales charts in an SUV-driven world, but the3-Series still has plenty of road left ahead of it. This compact executive four-door has been a pillar of BMW’s lineup for fifty years, valued as much for its reputation as for the way it drives.

The next chapter begins in 2026, when a new generation arrives in two distinct forms: the all-electric i3, codenamed NA0, and the traditional internal-combustion 3 Series, codenamed G50. If that sounds familiar, it’s because BMW’s been work-shopping this approach with their bigger sedans, the i5/5-Series and i7/7-Series.
The 3 Series and its EV sibling are now set to follow the same playbook, giving customers a choice between conventional gasoline power and fully electric performance.
Spied And Rendered
Recent spy shots of prototypes have revealed both gas-powered and fully electric versions of the next-gen 3-Series. While both share the “Neue Klasse” design language, the differences in proportions are telling.
The ICE testers feature a slightly longer hood, a sharper dash-to-axle ratio, and a more upright windshield. These elements combined make it look less like a complete EV-inspired redesign and more like an extensively reworked version of the current G20-generation BMW 3-Series.
These sightings have inspired digital artists Theottle and Kelsonic from Kolesa to create their own renderings of the next 3 Series, each offering an early glimpse of how the sedan’s styling might evolve.

BMW’s signature shark-nose design returns with a sharper, more athletic edge, framed by a fresh take on the kidney grilles. Slimmer and wider than on today’s models, the grilles now stretch across the front and now double as housing for sensors and tech that support advanced driver-assistance features. A deeper front bumper and lightly flared fenders complete the look, adding some muscle without drifting into excess.
Flush door handles bring the styling in line with BMW’s latest clean-surfaced aesthetic, while the greenhouse and Hofmeister kink stay intact.
Out back, heavy camouflage forces a little guesswork. Theottle’s rendering draws from the 2023 Vision Neue Klasse concept, with a full-width light bar and crisp LED signatures, while Kelsonic’s interpretation borrows slimmer light units reminiscent of the production iX3. Lower down, both envision sportier bumpers inspired by BMW’s M division, in line with prototypes wearing large alloys, upgraded brakes, and quad tailpipes.
Tech Blueprint From The iX3
While we have yet to get a glimpse of the 3-Series prototype’s interior during development testing, we have a pretty good idea of what to expect, largely thanks to the new iX3 that serves as the blueprint for BMW’s next generation of models.
At the center is the new Panoramic iDrive system that replaces the traditional instrument cluster with a wide digital display stretching across the full width of the dashboard. It places essentials like speed and electric range directly in the driver’s line of sight while allowing the rest of the information to be tailored to both driver and passenger. The screen itself is divided into three flexible sections, each configurable to suit individual preferences.
BMW will also offer an optional head-up display with animated guidance that counts down to the next turn. The setup is joined by a large, asymmetrically shaped infotainment touchscreen on the center console and a handful of physical switches for everyday functions.
Two Platforms, Two Paths
Unlike the i5/5-Series and i7/7-Series, where BMW paired EVs and ICE models on the same platform, the i3 and 3-Series are believed to head down different paths.
The all-electric i3 sedan will ride on the Neue Klasse architecture, shared with the upcoming iX3 SUV, while the combustion-powered 3-Series will reportedly stick to the CLAR platform, which also underpins the forthcoming G45 X3. This would explain the differences in proportions and styling details we see in the i3 and ICE 3-Series prototypes here.

Based on what we’ve seen with the mechanically related X3, the next-gen 3-Series will likely offer mild-hybrid upgrades of BMW’s proven 2.0-liter four-cylinder and 3.0-liter inline-six, with the latter forming the heart of the next M350. Both should see gains in efficiency and power over today’s units.
A Mild-Hybrid M3 Is In The Cards
Interestingly, even the mighty M3 isn’t immune to electrification. However, as BMW officials told us in a recent trip, the next M3 will forego the heavy plug-in hybrid setup of the M5, instead opting for a lighter mild-hybrid system. This should provide outputs in excess of the current ratings of 473 hp, 503 hp, and 523 hp, depending on whether you’re looking at the standard car, the Competition, or the Competition xDrive, not to mention the inevitable special editions.

Meanwhile, for those following BMW’s EV push, a quad-motor all-electric counterpart to the M3, possibly called the iM3, is already under development. With over 700 horsepower and near instant torque, it promises tire-melting lunacy for the brave few. And there may be more to come, as BMW has hinted the setup could be pushed past 1,300 horsepower, though whether that kind of excess ever makes it to production in some form of a special edition is another story.
The downside is weight, and plenty of it, as spy shots suggest the electric M3 could be at least 465 kg (1,025 lbs) heavier than today’s car. Hardly surprising, then, if carbon-ceramic brakes show up on the options list, just as they do on the current M3 and M4.
When Will They Arrive?
The current G20-generation BMW 3-Series first graced the stage in 2018, with minor facelifts arriving in 2022 and 2024. BMW has already confirmed the electric i3 for next year, and while it hasn’t given a timeline for the ICE 3 Series, it will most likely be introduced in 2026 as a 2027 model year, with the actual market launch possibly slipping into 2027.
