The BMW 7 Series G11 (short wheelbase) and G12 (long wheelbase) represents the pinnacle of luxury and technology from the Bavarian manufacturer during this period. Introduced in 2015, it innovates with its 'Carbon Core' structure integrating carbon fiber reinforced plastic (CFRP) to reduce weight and increase rigidity. The 2019 facelift (LCI) generated much discussion with the adoption of an oversized grille, but brought major technological updates (iDrive 7.0) and revised powertrains. Although demand for petrol and plug-in hybrid has increased, diesel powertrains (B57 family) remain the preferred choice in Europe for high-mileage drivers thanks to immense torque and remarkable efficiency. It is a technological showcase, which implies maintenance and repair costs commensurate with its stat
The BMW 7 Series G11/G12 is a formidable touring machine, offering a rare comfort/dynamism compromise in this segment. For high-mileage drivers, the 730d is the master choice: its B57 engine is a masterpiece of efficiency, provided that the EGR valve recall has been performed and intake cleaning is planned. The 740d offers appreciable extra power but adds complexity. Avoid the 750d out of warranty. If you drive less, the 740i (B58) is the safest and most reliable choice in the entire range. Avoid V8s (750i) from before 2019. Buying such a used vehicle requires a substantial maintenance budget (air suspension, star-marked tires, electronics): negotiate firmly and prioritize a model with a clear service history within the BMW network.
