By 2025, cumulative production exceeded 20 million units, underscoring the model's role as BMW's cornerstone product. In 2025, BMW celebrated the 50th anniversary of the 3 Series with special editions such as the M340i 50 Jahre, highlighting its enduring legacy. Sales of the BMW 3 Series have propelled it to become the brand's best-selling model, accounting for approximately 30% of BMW's annual global volume in recent years. Since 1975, over 20 million units have been sold worldwide, with the sedan variant alone reaching 10 million by 2015. The first generation (E21, 1975–1983) achieved around one million sales, establishing early momentum, while the third generation (E36, 1990–2000) exceeded 2.3 million units, benefiting from expanded body styles like the Touring wagon. The seventh generation (/G21, since 2018) has sold nearly three million units by 2024, contributing to the model's ongoing dominance. In 2024, the 3 Series represented approximately 30% of BMW's total global deliveries, rising to 25–35% in key markets such as and the .

Future developments

Eighth generation (G50; expected 2026)

The eighth generation of the 3 Series, codenamed G50 for the sedan variant and G51 for the Touring , represents a significant evolution in the model's lineup, with production slated to commence in November 2026 at BMW's plant in . This generation will introduce a refreshed inspired by the Neue Klasse , featuring a sharper "shark-nose" front fascia, slimmer and wider kidney grilles, flush door handles, and minimalist rear taillights divided by the BMW roundel. Unlike the all-electric i3 (NA0), which debuts earlier in 2026 on the dedicated Neue Klasse EV platform, the G50 maintains a combustion-engine focus while incorporating advanced mild-hybrid technology for improved efficiency and performance. The sedan is expected to hit markets as a 2027 , with the high-performance M3 (G84) following in 2028. Built on an updated version of BMW's Cluster Architecture (CLAR) platform, optimized for longitudinal inline engines and hybrid systems, the G50 emphasizes rear-wheel-drive dynamics with optional xDrive all-wheel drive. This architecture allows for a longer front overhang to accommodate inline-six powerplants, distinguishing it from the more compact EV counterpart. Interior updates are anticipated to include a panoramic iDrive interface with curved displays, sustainable materials, and enhanced digital assistant features, aligning with BMW's broader push toward connected vehicle technologies. Spy prototypes reveal quad exhaust tips on M-badged variants like the M350 and future M3, signaling retained performance heritage. Powertrain options for the G50 will center on mild-hybrid engines, starting with a 2.0-liter turbocharged four-cylinder producing approximately 255 horsepower in base models like the 330i, paired with an eight-speed . Higher trims, such as the M340i successor, will employ a 3.0-liter turbocharged inline-six (B58 family) delivering around 386 horsepower, also augmented by a 48-volt mild-hybrid system for smoother operation and reduced emissions. BMW has confirmed that the next-generation M3 will adopt a similar mild-hybrid setup rather than a configuration, prioritizing track-ready responsiveness. Diesel variants may return in select markets, but remains limited to mild-hybrid assistance in this ICE-focused lineup, complementing the parallel i3 EV. These developments underscore BMW's strategy to bridge traditional sports sedan appeal with modern efficiency demands amid tightening global emissions standards.

Electrification and sustainability initiatives

The BMW 3 Series has incorporated electrification primarily through electric (PHEV) variants, starting with the G20/G21 generation introduced in 2019. The lineup expanded in 2020 to include four PHEV models: the 330e Sedan, 330e Touring, 330e xDrive Sedan, and 330e xDrive Touring, each combining a 2.0-liter four-cylinder (135 kW/184 hp) with an (83 kW/113 hp) for a system output of 215 kW/292 hp via XtraBoost. These models feature a 12.0 kWh lithium-ion high-voltage battery enabling provisional electric ranges of 55–68 km (WLTP), with CO₂ emissions of 36–46 g/km, supporting local emission-free driving and eligibility for incentives under Germany's Electric Mobility Act. In 2024, the 330e received a battery upgrade to 19.5 kWh, increasing the electric range to approximately 63 km (WLTP) while maintaining CO₂ emissions under 50 g/km, continuing the strategy to reduce life-cycle CO₂ emissions by 40% per vehicle compared to 2019 levels, with production at the plant powered entirely by sources. Sustainability initiatives for the 3 Series emphasize principles and resource efficiency under the BMW Group's "Secondary First" strategy, which prioritizes recycled and secondary raw materials to minimize virgin resource use. In the current generation, cast aluminum components incorporate up to 50% secondary materials, while wheel rims use up to 70% recycled aluminum, contributing to an overall reduction in production-related CO₂ emissions. The BMW Group achieved 99.5 g/km fleet CO₂ emissions in 2024—exceeding targets by over 30 g/km—partly through electrified models like the 3 Series PHEVs, which emit under 50 g CO₂/km (WLTP). Broader efforts include 95% recyclability of end-of-life vehicles and partnerships to recover materials like , , and , with the 3 Series benefiting from these across its to support the group's net-zero CO₂e target by 2050. Looking ahead, the eighth-generation G50 will continue with mild-hybrid powertrains, while its all-electric counterpart, the i3 (NA0) on the Neue Klasse platform, will enter production in November 2026 at the and plants. This model will integrate sixth-generation eDrive technology for enhanced efficiency, targeting over 50% electrified vehicle share in BMW's portfolio by decade's end, with design-for-circularity features like increased secondary materials in batteries and components to further decarbonize the lifecycle. The Neue Klasse platform aims for up to 30% greater range and 20% faster charging compared to prior generations, aligning with BMW's goal of 40 million tonnes CO₂e reduction by 2030 through Scope 1, 2, and 3 emissions cuts.
