Summary
BMW has begun series production of the eighth-generation 3 Series Sedan at its Dingolfing plant. Combustion-engine versions are being made first, with plug-in hybrids planned from 2027.
BMW Group says series production of the eighth-generation BMW 3 Series Sedan began this week at its Dingolfing plant in Germany. The company announced the start on 3 November 2026. The first versions have combustion engines; plug-in hybrid powertrains are planned for the plant from 2027. The model’s market launch is scheduled to take place in stages from the first quarter of 2027.
The production plan pairs the combustion and plug-in hybrid sedan at Dingolfing with the all-electric BMW i3, which is being produced at BMW’s Munich plant. BMW says the new sedan incorporates technologies associated with its Neue Klasse vehicles, including BMW Panoramic iDrive, a new electrical and electronic architecture, and updated driver-assistance systems.
Production split between Dingolfing and Munich
Dingolfing will build the 3 Series Sedan alongside BMW 4 Series and 5 Series models on a shared assembly line. BMW says the line’s equipment can accommodate different powertrain variants, allowing vehicles with different propulsion systems to use common production structures. The company reports that around €1 billion has been invested in developing the Munich and Dingolfing vehicle plants for this production arrangement.
A vehicle’s electrical and electronic architecture is the arrangement of its onboard electronic systems and the way they are connected. BMW identifies a new architecture as one of the Neue Klasse technologies integrated into the sedan, but its announcement does not detail the system’s design or functions. Panoramic iDrive is another change that required adjustments to cockpit pre-assembly.
Some components will come from BMW Group Plant Landshut, including crankcases and cylinder heads for four- and six-cylinder engines, and the propeller shaft. Landshut also makes interior parts such as the instrument panel. BMW says a newly developed lighting system there uses an integrated light box to illuminate different cockpit surface materials.
Existing factory structures adapted for the new model
BMW says the sedan can be built largely on existing paint-shop and assembly lines using modular processes. The plant installed a new powertrain-neutral production line in its existing body-shop building. Around one third of the approximately 750 robots used in production, along with other equipment, were reused from existing facilities.
The company also describes automated adjustment of doors and closures, automated surface inspection, and more automated inbound logistics. About 250 Smart Transport Robots work with automated forklifts and Splitbots to move incoming goods and supply materials to production. These measures fit BMW’s iFACTORY approach, which the company says combines lean production with resource conservation and digitalisation.
The production start begins the series-production ramp-up; it is not the market launch. BMW plans to bring the new sedan to market in stages from the first quarter of 2027. Dingolfing has produced more than 1.15 million BMW 3 Series vehicles to date, according to the company, and previously built several sedan generations through 2004.
