BMW is reintroducing its formidable turbo-diesel inline-six engine to the 2025 X3 range, with the X3 40d xDrive set to join the European lineup from May. This electrified powerhouse marks a significant enhancement to the popular luxury SUV's powertrain offerings, combining impressive performance with modern efficiency technologies.
Power and Performance Specifications
The new X3 40d xDrive demonstrates BMW's expertise in diesel technology:
| Specification | Detail | Improvement |
|---|---|---|
| Engine Type | 3.0L turbo-diesel I6 | 48V mild-hybrid |
| Power Output | 223kW | +28kW |

Advanced Powertrain Technology
The integration of 48-volt mild-hybrid technology with the inline-six diesel engine represents BMW's sophisticated approach to meeting modern efficiency demands while maintaining performance expectations. The system provides additional electrical boost during acceleration while enabling smoother stop-start operation and enhanced energy recovery during deceleration.
Global Manufacturing Strategy
BMW's production strategy for the X3 reflects the complex nature of global market demands:
- European-market X3 40d xDrive models will be manufactured at BMW Group Plant Rosslyn in South Africa
- Australian-bound X3 variants continue production at the Spartanburg facility in the USA
- This split production approach allows BMW to optimize manufacturing efficiency and market-specific customization
Fourth-Generation Innovations
The latest X3 represents a comprehensive evolution of BMW's successful SUV formula:
- Exterior dimensions have grown strategically to enhance presence and interior space
- Interior technology takes a significant leap forward with the curved display setup
- 12.3-inch digital instrument cluster provides customizable information
- 14.9-inch central touchscreen running BMW's latest Android-based Operating System 9
- Enhanced connectivity and user interface features
Australian Market Context
While Australian buyers won't have access to the powerful diesel variant, the local X3 range maintains strong market positioning:
- Entry-level X3 20 xDrive starts at $84,500 (a $2,800 increase)
- Range-topping M50 xDrive priced at $126,900 (minimal $100 increase)
- Comprehensive standard equipment across the range
- Focus on petrol and electrified powertrains for local market
The return of the inline-six diesel to the X3 range demonstrates BMW's nuanced approach to different market demands. While many manufacturers are moving away from diesel technology, BMW recognizes that in certain markets, particularly Europe, modern diesel engines still offer an attractive combination of performance and efficiency.
The decision not to offer the 40d xDrive in Australia reflects the different market conditions and buyer preferences in our region. However, the broader X3 range continues to offer compelling options for luxury SUV buyers, with a mix of powertrains suited to local preferences and conditions.
The technical specifications of the X3 40d xDrive are particularly impressive, offering performance that would have been considered sports car territory not long ago, combined with reasonable fuel efficiency. The integration of mild-hybrid technology shows BMW's commitment to modernizing traditional powertrains while maintaining their core appeal.
For European buyers, the X3 40d xDrive represents an attractive proposition - combining luxury, performance, and efficiency in a practical package. While Australian buyers might miss out on this particular variant, the continued evolution of the X3 range ensures it remains a strong contender in the competitive luxury SUV segment.
