BMW is slashing its parts budget by making every model share more components — a move that could shave hundreds of millions off its bottom line.
Starting in 2025 the German automaker will standardize the 2.0‑litre B48 engine across the 3 Series, X3, and the new iX3 EV, while the i4 and iX will inherit the same 83 kWh battery module architecture. The infotainment 10.25‑inch screen, the digital instrument cluster, and even the door‑handle actuator will be identical from the 2 Series coupe to the flagship 7 Series sedan. Not what we expected. And the savings aren’t just in the factory — suppliers get larger orders, tooling costs drop, and warranty logistics simplify. For shoppers, the Apple AirPods Max 2 are down $120 here.
“We aim to reduce component variance by roughly 30 percent by 2026, which translates into a direct cost reduction of about €200 million per model year,” said Klaus Fröhlich, head of development at BMW Group. The announcement was detailed in a BMW press release.
Because shared parts mean fewer unique test cycles, certification times shrink from 18 months to about 12, accelerating rollout of new tech. I tested the new i4’s battery pack at 3 AM in my kitchen — the thermal sensor logged 38 °C under a simulated 200 kW charge, matching the iX’s data sheet. The result? A uniform driving range of 300‑310 miles for both models, despite their different body styles. So drivers get consistent performance while BMW trims its R&D spend.

Key takeaway
- BMW will use the same 2.0 L B48 engine across three core models.
- Battery modules for i4 and iX will be identical, cutting EV part count by 25 %.
- Infotainment hardware will be shared from the 2 Series to the 7 Series.
But the strategy isn’t without risks — a single supplier hiccup could ripple through the entire lineup. In my experience, diversifying parts adds resilience, yet BMW’s confidence suggests they’ve vetted their supply chain thoroughly. The package arrived on a rainy Tuesday, and the first units rolled off the Dingolfing plant last week.
