730i (231 Hp) Steptronic Verdict:
Performance Verdict
The inline-six petrol offers adequate performance, but can feel a bit strained when pushed hard in such a heavy car.
Fuel Economy
Moderate fuel consumption, better than the V8s but not outstanding for its power output.
Pros and Cons:
Pros:
- • Luxurious and spacious interior with high-quality materials
- • Powerful and refined engine lineup, from efficient diesels to the potent V12
- • Exceptional ride comfort and stable highway cruising ability
- • Advanced technology for its time, including adaptive cruise control and active roll stabilization
- • Distinctive and commanding road presence
Cons:
- • Complex and often problematic iDrive infotainment system
- • Polarizing exterior design, especially the 'Bangle Butt' rear styling
- • High running costs, including fuel, maintenance, and potential electronic repairs
- • Significant depreciation, making early models a 'bargain' but with potential for expensive fixes
- • Some engine variants (e.g., N62 V8) are known for specific reliability issues like valve stem seals
