The most expensive BMW 3 Series you can build today rings in at €101,655. That is not a typo, and it is not an M3. It is the M350 xDrive sedan, the range-topping variant of the brand-new G50 generation, loaded with every option the German configurator currently offers.
BMW launched the build tool just hours after revealing the eighth-generation 3 Series earlier this week. With diesel variants eliminated and the plug-in hybrid delayed until next year, only three gasoline models are available: the 318, the 320, and the M350 xDrive. The M Performance model starts at €80,900 and climbs from there in a hurry.
Nearly €21,000 in extras will get you to that six-figure threshold. The single priciest tick box is the €4,300 M Technology Package II, which bundles 20-inch wheels, sport tires, upgraded engine cooling, and an Individual leather interior with M Sport seats. A separate set of 18-inch winter wheels and tires runs €3,000.
A five-year, 100,000-kilometer service plan adds €3,097. A roof box capable of swallowing 550 liters costs €1,099.
Then come the smaller charges that pile up fast. A heated steering wheel is €320. An electrically operated trunk is €450. Crystal-effect switchgear is another €320. Heated rear seats, €400. The Harman Kardon 16-speaker audio upgrade, €350.
A towbar runs €1,150. Ocean Wave Blue paint is €990. A Security Assistant package with online services tacks on €480.
Individual colors have not yet been embedded in the configurator. When they arrive, starting with Frozen Space Silver in March 2027, the ceiling will climb higher still.
The uncomfortable math here is simple. A fully loaded 3 Series now costs roughly the same as an M3 Competition before you start adding options to that car. The next-generation M3, codenamed G84, is not expected until 2028, and it will push deep into territory that used to belong to the 5 Series and above.
At the opposite end of the scale, the entry-level 318 starts at €49,900. That is less than half the loaded M350’s price, and the base car actually looks respectable in Alpine White with 18-inch wheels and a cloth interior. The gap between floor and ceiling in a single model line has never been this wide for a 3 Series.
Production of the G50 begins next month at BMW’s Dingolfing plant. One notable feature will be missing at launch: the M350 xDrive’s rear-wheel-drive mode, marketed as “Drift Moment,” will not be available until later next year. BMW says it will be added at the factory for new builds and offered as a retrofit through an over-the-air update.
A generation ago, a fully optioned 3 Series barely cracked €70,000. Two generations ago, the idea of a six-figure compact sedan would have been laughed out of the room. BMW’s option strategy has always been aggressive, but the G50 represents something different.
The 3 Series was built to be the accessible entry point to the brand’s sedan lineup. When the base model starts at nearly €50,000 and the top trim crosses €100,000, the definition of “accessible” has clearly shifted.
If the rumored G88 Touring wagon materializes, it will carry a premium over the sedan. And once Individual paint codes populate the configurator, even the current ceiling is not the real ceiling. The most expensive 3 Series has not actually been built yet.
