BMW is pursuing a dual-powertrain strategy for its next-generation 3 Series lineup, committing €2 billion to simultaneously develop an all-electric i3 saloon and an updated petrol-powered equivalent. While the automaker’s X1 SUV leads its sales volume, the 3 Series remains its cultural anchor, prompting Munich to cater to conservative buyers hesitant to make an immediate transition to electric vehicles.
Platform Sharing and Distinct Styling Choices
Both the upcoming all-electric i3 and the updated petrol 3 Series share the same sharp-suited exterior design language, featuring cleaner lines than outgoing models and a broad, slim front grille. However, structural differences emerge at the rear of the vehicles. The petrol 3 Series appears taller and bulkier to accommodate a traditional boot, fuel tank, and exhaust system, whereas the shrink-wrapped electric i3 optimizes its dedicated packaging. The initial petrol model showcased by BMW is the range-topping M350 variant, equipped with a turbocharged 3.0-litre straight-six engine producing 443 horsepower. This setup drives the saloon from zero to 100 km/h in 4.1 seconds. In comparison, the electric i3 M50 delivers a heavier 469 horsepower, reaching the same speed mark in 4.7 seconds.
Pricing and Running Costs Comparison
Fuel economy figures released by BMW list the M350 petrol model at 8.2 litres per 100km, putting a 230km trip from Dublin to Cork at roughly €37 in fuel costs at current pump prices. Conversely, home charging an electric i3 M50 for the same journey can cost as little as €14. Purchase pricing further differentiates the lineup across markets. BMW Ireland lists the entry-level petrol 320 starting at €71,935, with the M350 priced at €111,585. Meanwhile, the electric i3 M40—featuring a smaller battery and a 710km range—begins at €60,285, while the 900km-range i3 M50 costs €67,215.
Manufacturing Locations and Powertrain Diversity
To accommodate drivers lacking home-charging access and those demanding alternative configurations, BMW is expanding the 3 Series portfolio beyond pure electric and high-performance petrol options. The lineup includes a mild-hybrid petrol 320 model alongside an anticipated replacement for the long-range plug-in hybrid 330e, which targets up to 150km of electric-only driving range. Diesel variants will remain available in select global markets outside Ireland. Inside the cabin, both versions adopt a full-width ‘Panoramic View Display’ instrument panel stretching across the windscreen, paired with a driver-oriented, rhombus-shaped central touchscreen reminiscent of classic 1980s BMW interiors. Production is split between German facilities. The electric i3 will roll off the assembly line at BMW’s headquarters factory in Munich, while the petrol and plug-in hybrid models will be manufactured nearby in Dingolfing. “We are investing in value creation, competitive production and job security in Germany,” BMW stated regarding the dual-pathway rollout. The company is also establishing a high-voltage battery plant in Irlbach-Straßkirchen to internalize key electromobility components at its domestic manufacturing base.
